Understanding Harmonics and Their Impact on Power Systems

Harmonics in electrical power systems refer to currents or voltages with frequencies that are whole multiples of the fundamental power frequency. For example, if the base frequency is 60 Hz, the second harmonic would be at 120 Hz, and the third at 180 Hz. The electricity supplied to a property may not always be 'clean', and properties can experience harmonics. These harmonics come from non-linear loads, such as electronic devices that draw current in pulses rather than a smooth wave.

This sudden change in current flow injects harmonic currents into your power system, which can cause various power quality issues. These issues can appear as voltage dips and swells, imbalances in voltage or current across electrical phases, and flicker effects caused by repetitive switching of electrical loads. You can notice these problems through signs like flickering lights, overheating transformers, and breakers that trip frequently.

The state of harmonics in your system is represented by Total Harmonic Distortion (THD), a measure of all harmonic effects. It's typically measured up to the 50th multiple of the base frequency of the power system, which is 3kHz or, per some guidelines, the 40th multiple (2.4kHz).

Poor power quality due to harmonics can cause several problems, such as:

  • Increased power consumption leading to higher installation and utility bills.
  • Overheating of equipment.
  • Decreased profitability.
  • Potential damage to your equipment.
  • Overheating in neutral conductors and distribution transformers.
  • Decreased equipment reliability and lifespan.
  • Increased maintenance requests and downtime.
  • Higher electricity costs.

These additional frequencies distort the AC sine wave in an electrical circuit and can have serious consequences, including reducing the life of your equipment. Now that we've discussed the effects of harmonics on your power systems let's discuss how harmonic filters can help tackle these issues.

Introduction to Harmonic Filters

In understanding harmonic filters, you will explore the basic principles of active and passive harmonic filters. You will gain insight into their unique features and how they function. Let's start this informative journey.

Active Harmonic Filter Basics

Active Harmonic Filters (AHFs) present a modern answer to the issue of harmonic distortions in power systems. They employ cutting-edge technology to detect and study the harmonics in the network. A Central Processing Unit (CPU) then generates a harmonic current that opposes the measured spectrum. It introduces this counteractive current into the system in real time, effectively neutralising all existing harmonics.

We can categorise active filters into three types, each with its unique benefits:

  • Shunt active filters: These connect parallel to the load and estimate the harmonic current from the load. They generate a compensating current that neutralises the harmonic component.
  • Series active filters: These connect in series to the power system and inject voltage that cancels out the harmonic voltage in the system. This ensures that the load receives a stable voltage.

The primary benefits of active filters lie in their ability to enhance the power factor. They supply both capacitive and inductive reactive power, making them a sophisticated solution for harmonic filtering. Active filters can adapt to changing harmonic influences and filter out multiple harmonic frequencies simultaneously. They employ sophisticated power electronics and control algorithms to dynamically decrease harmonic distortion, injecting compensating currents into the power system. This results in a cleaner, more stable power supply.

Active filters hold several advantages over passive filters:

  • They can eradicate multiple harmonics simultaneously.
  • They adapt to changes in the power system frequency and the harmonic spectrum.
  • They don't create resonance problems in the power system, unlike passive filters.
  • They actively generate a reverse compensation current that cancels out various harmonic components, thereby improving power quality parameters such as voltage regulation and unbalance.

AHFs, also known as Active Power Filters (APFs), represent a new breed of power electronic equipment. They employ high-speed DSP devices and modern power electronics technology. They actively suppress harmonics and compensate for reactive power. AHFs are adaptive and can respond to a wide range of harmonic frequencies, making them a versatile solution for various power system configurations. Voltage fluctuations and harmonics can trigger grid disturbances and result in overheating and escalated energy bills. An AHF can mitigate these problems, producing a result better than 5% Total Harmonic Distortion (THD) across the load range, improving the power factor and balancing the load on all three phases if required.

With their adaptive nature and superior technology, Active Harmonic Filters provide an effective solution to the challenges posed by harmonic distortions in power systems. We will now look into the basics of Passive Harmonic Filters and their comparison with Active Harmonic Filters.

Passive Harmonic Filter Basics

Passive Harmonic Filters (PHFs) work on the principles of basic electrical circuit theory. They use resistors, inductors, and capacitors to eliminate unwanted frequencies. These components work together in different ways to create a specific filtering effect.

The success of a PHF in removing harmonics heavily depends on its design and position within the power system. Designing involves choosing the right values of resistance, inductance, and capacitance to create the desired filtering effect. For the best harmonic elimination, you should place the filter near the harmonic source.

A PHF's job is to allow certain frequencies and block others. It accomplishes this by using the unique responses of capacitors and inductors to different frequencies. In power systems, PHFs are designed to 'trap' harmonic frequencies, letting only the base frequency pass. This is achieved by making the filter's impedance high at the harmonic frequencies and low at the base frequency.

There are various types of PHFs, each with its unique response to frequency and circuit setups. These include:

  • Single-tuned filters
  • Double-tuned filters
  • High-pass filters

Although PHFs are relatively simple and cost-effective, they don't offer the flexibility of Active Harmonic Filters (AHFs). Changes in system operation can also affect their performance.

PHFs use passive components like reactors and capacitors, which are tuned to a specific frequency to filter out a particular harmonic part and reduce the resulting harmonics. They also compensate for reactive power, improving the power factor. Let's now compare these to their active counterparts.

Active Harmonic Filter vs Passive: A Scientific Analysis

The world of harmonic filters presents two primary types: active and passive. Each carries unique strengths and weaknesses, and your selection hinges on multiple factors. You need to evaluate their effectiveness in diminishing harmonics, their cost-efficiency, the upkeep they demand, and their flexibility and adaptability under varying power system conditions. Now, let's commence this comparative exploration.

Efficiency Comparison

Several factors can influence the efficiency of both Active Harmonic Filters (AHFs) and Passive Harmonic Filters (PHFs), including the specific harmonic frequencies in the system, the load conditions, and the design and location of the filters. Both AHFs and PHFs play a crucial role in reducing harmonics in power systems, but they function differently and offer varying levels of efficiency. Let's explore how these differences affect their efficiency.

Here are some key differences between AHFs and PHFs:

  • AHFs can reduce multiple frequencies simultaneously.
  • PHFs typically filter individual harmonics.
  • AHFs can actively adjust to changes in the power grid's harmonic current within a certain range.
  • PHFs can only reduce the harmonics of fixed orders (3,5,7) within a certain frequency range.

When it comes to safety, AHFs avoid overloading when the active filter limit is reached, unlike PHFs. Moreover, if an AHF becomes incapacitated, it won't affect the motors it optimises power for. This brings us to an important consideration when comparing the two.

Thus, while both AHFs and PHFs play their roles and offer benefits, it's clear that AHFs offer superior efficiency and safety in managing power system distortions.

Cost Comparison

Deciding between Active Harmonic Filters (AHFs) and Passive Harmonic Filters (PHFs) is vital for your business because they come with different cost implications. Let's examine their costs.

At first look, AHFs might seem pricier for a single-drive application. However, their cost-effectiveness grows as the number of non-linear loads increases. This happens because one AHF can correct multiple loads, thus making it a more budget-friendly choice in the long term.

Conversely, PHFs are typically more cost-effective for applications with a large, single, non-linear load. The capital expenditure for one AHF is usually higher than that of a PHF. But, if constant output holds the utmost importance, AHFs are the suggested solution. Despite the higher initial cost, AHFs can significantly reduce energy expenses and ensure consistent output, enhancing your business's net income.

You should consider factors like the specific harmonic frequencies in your system, the load conditions, and the design and placement of the filters when deciding between AHFs and PHFs.

While you must consider the initial investment and future maintenance costs, it's also crucial to take into account the specific needs of your power system when deciding between AHFs and PHFs. Let's shift our focus to the maintenance aspect of these filters.


Both active and passive harmonic filters present unique advantages and disadvantages regarding maintenance. External harmonics can affect Passive Harmonic Filters (PHFs), causing overheating and posing challenges in sizing due to the unpredictability of their impact.

Some modern PHFs, which technicians install on the cold side of wye-connected electrical sub-panels and ground applications, are passive and inductive. These devices do not require any third-party electrical components, eliminating the need for maintenance.

Active Harmonic Filters (AHFs), also known as harmonic correction units (HCUs), offer a more sophisticated solution for managing power system distortions. Unlike passive filters, AHFs can adapt and react to a broad spectrum of harmonic frequencies. This adaptability makes them a flexible solution for various power system configurations.

An active harmonic filter system consists of three main parts:

  • A module that detects harmonic
  • A control module
  • An inverter bridge module

However, maintaining AHFs is not as simple. While AHFs are generally more sophisticated and adaptable than PHFs, their complexity and the incorporation of power electronics might require more frequent maintenance. The specific frequency of this maintenance largely depends on the AHF model and the manufacturer's instructions.

On the other hand, passive filters employ a slower method known as contactor switching. Any changes in the frequency of the passive filters can alter the resonance point, diminishing the harmonic filtering effect.

In terms of operating costs:

  • Active harmonic filters might incur higher costs due to the necessity for constant monitoring and maintenance. Regular checks and adjustments are crucial to ensure the filter continues to operate optimally as the conditions of the power system change over time.
  • Installing a Passive Harmonic Filter on each drive can be a less intrusive compensation method as it does not require any ongoing maintenance.

After discussing the maintenance aspects, the next consideration is the adaptability and flexibility of these filters.

Flexibility and Adaptability

Active Harmonic Filters (AHFs) and Passive Harmonic Filters (PHFs) both have a role in reducing harmonic distortion in power systems. However, their flexibility and adaptability vary greatly. AHFs use power electronics and control algorithms to dynamically fight against harmonic distortion. They inject opposing currents into your power system, neutralising unwanted harmonics. The result? A cleaner, more stable power supply.

Conversely, Passive Harmonic Filters (PHFs) usually comprise reactive components like inductors, capacitors, and resistors. External harmonics from the mains can influence these components, potentially causing them to overheat. This unpredictable interference of external harmonics can make the task of sizing these passive harmonic filters quite challenging.

Active Harmonic Filters come with the following advantages:

  • They can adapt to a broad spectrum of harmonic frequencies, making them a flexible solution for different power system configurations.
  • Across the load range, Active Harmonic Filters can bring down Total Harmonic Distortion (THD) to less than 5%.
  • If needed, they also have the potential to enhance the power factor and evenly distribute the load across all three phases.

Therefore, given the adaptability of AHFs versus the specificity of PHFs, AHFs offer more flexibility. The choice between the two will hinge on the specific needs of your power system.

Choosing the Right Harmonic Filter: Factors to Consider

The process of selecting the appropriate harmonic filter for your power system isn't a minor task. It demands a comprehensive understanding of the specific requirements of your system and consultation with experts in the field. So, let's begin discovering the ideal harmonic filter for your needs.

Understanding Your Power System

Comprehending the specific requirements of your power system is an essential part of choosing a harmonic filter. This process involves determining the extent of harmonic distortion that needs addressing. For instance, when your power system includes a variety of load types, such as UPS, VFD, and DC drives, active filters often emerge as the best option.

Harmonic filters work by redirecting specific harmonic currents. Interestingly, engineers design some filters specifically to redirect harmonics of certain frequencies.

In this scenario, it's worthwhile to mention the IEEE 519-2022 standard. This guideline aids in designing electrical systems containing linear and nonlinear loads. It describes the voltage and current waveforms across the system, establishes waveform distortion goals for system designers, and explains the connection between sources and loads.

Considering the variety of power systems, understanding the differences between active and passive harmonic filters is crucial:

  • Active Harmonic Filters: These filters are mainly used in situations where the harmonic component and size change frequently and the harmonic composition is complex.
  • Passive Harmonic Filters: These filters are more appropriate for scenarios where the harmonic components and size remain relatively stable and the harmonic components are less complex.

Is an active harmonic filter better than a line reactor?

Active Harmonic Filters and Line Reactors have roles in managing harmonics in power systems, yet their methods differ. Active Harmonic Filters balance out harmonic distortion by generating currents that counteract it. They can function without Line Reactors, but issues might occur if the filter and the load lack sufficient impedance. In contrast, Line Reactors protect Variable Frequency Drives from power spikes and manage the inrush current flowing into the drive's rectifier. Whether you choose an Active Harmonic Filter or a Line Reactor depends on your power system's unique requirements.

What are the key differences between active and passive harmonic filters?

Active Harmonic Filters and Passive Harmonic Filters both control harmonics, yet their methods differ. Active Harmonic Filters eliminate harmonic components using power electronics. They add active power, matching the harmonic frequency but in the opposite phase, thereby neutralising the harmonic. Conversely, Passive Harmonic Filters employ passive elements such as resistors, capacitors, and inductors. These filters adjust to a particular frequency. Choosing between an Active Harmonic Filter or a Passive Harmonic Filter hinges on your power system's specific requirements.

What are the advantages of using an active harmonic filter instead of a passive filter?

Active Harmonic Filters (AHFs) outperform Passive Harmonic Filters in many ways. AHFs adapt more and perform better. They manage to keep the Total Harmonic Distortion (THD) under 5%, even with a load as low as 10%. In contrast, not every Passive Filter can meet the 8% or 5% THD IEEE-519 specification, even at maximum load. Unlike passive filters, AHFs do not lead to a power factor without load. You can put AHFs anywhere in the lineup, while passive filters require installation at each Variable Frequency Drive (VFD). When handling multiple VFD loads, AHFs are more cost-effective and save more space than passive filters. Want to delve deeper into the advantages of active over passive harmonic filters? Head over to our blog “Why Choose Active Harmonic Filters Over Passive Harmonic Filters?

How can an active harmonic filter improve power quality?

Active Harmonic Filters, or AHF, enhance power quality by eliminating harmonics. These harmonics can trigger protective devices, interfere with delicate equipment, and distort voltage. AHFs counteract these unwanted harmonics by releasing counteractive currents, purifying and stabilising the power supply. This action not only protects delicate electronic equipment but also improves energy efficiency and minimises the risk of costly downtime. Moreover, AHFs contribute to the power factor of the electrical system. They lessen both thermal and electrical stress on the electrical infrastructure, paving the way for long-term energy efficiency and cost savings.

What maintenance is required for active harmonic filters?

Maintaining Active Harmonic Filters (AHFs) regularly is key to their optimal performance. This involves a few critical steps.

  • Inspect the AHF's physical condition regularly to identify any damage, loose parts, or signs of wear and tear.
  • Stay alert for software updates from the manufacturer. These updates enhance the AHF's performance and rectify any issues or bugs.
  • Verify the AHF's calibration to ensure its accurate reading and response to electrical conditions.
  • Monitoring the operational temperature of the AHF is also crucial. Overheating can impair its performance and potentially cause damage.

Following these steps, you can ensure your AHF remains current and accurate, offering dependable power quality management.

How can you quantify the return on investment from installing an active harmonic filter?

An Active Harmonic Filter (AHF) investment can offer several benefits.

  • Energy Savings: AHFs boost power quality, which translates to significant energy savings over time.
  • Reduced Equipment Downtime: AHFs prevent equipment failure and cut downtime, resulting in cost savings.
  • Longer Equipment Lifespan: AHFs extend your equipment's lifespan by reducing the heat and electrical stress from harmonics.
  • No Penalties: AHFs help you comply with power quality standards, saving you from utility company fines.

Remember, the exact return on investment will vary based on your unique situation and power system.

What factors should be considered when selecting an active harmonic filter supplier?

When you need to choose a supplier for an Active Harmonic Filter (AHF), remember these key factors:

  • Inverter Topology: Many current AHFs build on a 3-level NPC inverter topology. It's a step up from the older 2-level topology and brings numerous benefits.
  • Losses: The losses an AHF might have can swing wildly. It hinges on both the design and the topology of the AHF.
  • Response Time: Some power quality problems can crop up in a flash. That's why the AHF's response time needs to beat that speed.
  • Harmonic Compensation Capacity: How well an AHF can balance a specific harmonic order matters a lot. It can heavily influence the whole system's performance.
  • Electromagnetic Compatibility (EMC): A few countries enforce stringent rules about EMC. It's crucial to remember this when you're picking an AHF.

Analyzing the Key Differences Between SMF and Tubular Batteries for UPS Systems

Batteries seem to be everywhere, don't they? They power your car, your phone, and even your wristwatch. But when it comes to understanding the difference between SMF and Tubular batteries, you might find it a bit complex. Looking for the most reliable and efficient option? This article aims to clear up any confusion. Here is a comprehensive analysis comparing these two types of batteries, delving into key aspects, including efficiency, life-cycle assessment, and environmental implications. So, sit back and get ready to make an informed choice.

Understanding SMF and Tubular Batteries

In your journey to comprehend batteries, you've likely encountered SMF and Tubular batteries. But what do they represent, and how do they function? We need to scrutinise these two categories of batteries, their architecture, and their fundamental operating principles. This scrutiny provides a robust base to grasp the DIFFERENCE BETWEEN SMF AND TUBULAR BATTERY.

What is an SMF Battery?

An SMF, or Sealed Maintenance-Free battery, falls under the category of lead-acid battery. It's sealed and requires no maintenance or topping up of the electrolyte, making it an ideal choice for places with certain restrictions.

SMF batteries come in various designs to meet diverse needs. Here are the common types:

  • Small 6V versions: These are suitable for emergency lights and telecom instruments.
  • 12V versions: These are ideal for vehicles and offline deep-cycle UPS systems.
  • Larger deep cycle SMF batteries: These have capacities up to 100 Ah and are perfect for online UPS systems and car starter technologies.

A standout feature of SMF batteries is their maintenance-free nature. They don't require water or acid top-ups due to their sealed design. This sealing ensures they are leak-proof in the right conditions, eliminating worries about battery acid leakage or water loss during the charge-discharge cycle.

SMF batteries don't emit lead fumes, which adds to their versatility. You can place them near electric equipment or in enclosed rooms without any concerns. Having understood the basics of SMF batteries, it is essential to explore how they stack up against another popular choice - tubular batteries.

What is a Tubular Battery?

Tubular batteries, a larger version of the lead-acid battery, serve frequently in UPS and inverter systems. The name "tubular" springs from the battery's unique design, which flaunts vertically arranged tubes. This clever arrangement not only enhances current flow but also decelerates the corrosion process. Let's look closer at its structure.

The positive plate of a tubular battery resides within a cloth-wrapped tube, which contains the power of the battery's electrodes. This creative design element enhances the battery's performance and extends its lifespan.

Tubular batteries earn acclaim for their durability and ability to provide power for long periods. They also offer more convenience because they need fewer water refills compared to flat plate batteries. Here are some notable benefits of tubular batteries:

  • Warranty: They typically include a longer warranty period, providing up to 6 years of assurance.
  • Temperature Tolerance: They can endure extreme temperature changes and easily convert a major power surge into a minor voltage shift.
  • Charging Cycles: They offer a higher number of charging life cycles and superior thermal management compared to flat-plate batteries.

In terms of size, tubular batteries come in two versions: short and tall. Short tubular batteries, wider and more compact, are easier to transport. Conversely, tall tubular batteries provide a longer standby period and are ideal for homes with ample storage space.

In the lead-acid battery world, tubular batteries, with their innovative design and robust performance, are clearly in the lead. This is a significant difference between SMF and tubular batteries. In the next section, we'll examine the efficiency of these batteries.

Efficiency of SMF vs Tubular Batteries

As you investigate batteries, understanding the efficiency of various types becomes essential. Two common types you're likely to come across are SMF and tubular batteries. Each holds unique strengths and weaknesses, especially in terms of energy output, charge retention, and operational conditions. So, we're ready to begin understanding the complexities of these battery types.

Efficiency of SMF Batteries

The AGM variant of the SMF battery stands out for its efficient power delivery and adaptability to various climate conditions. These batteries charge more rapidly and require less time to recharge than their flooded counterparts, thanks to their effective power delivery.

SMF batteries earn praise for their durability and consistent performance. They are available in different designs, some with a flooded acid cell layout for starter engines or a gel electrolyte for deep-cycle applications. The industry currently prefers options that are specific to particular applications. These come with improved recharge and discharge capabilities, which increase their appeal.

SMF batteries can function in a temperature range from -20 degrees C to 60 degrees C. This gives them a wider adaptability range to different climate conditions compared to flooded lead-acid batteries.

Although SMF batteries might have a higher initial cost, their longer cyclic life and lack of maintenance needs result in cost-effectiveness over time. After discussing the efficiency of SMF batteries, we will focus on another type of battery - Tubular batteries.

Efficiency of Tubular Batteries

Tubular batteries are crucial in renewable energy systems, off-grid energy solutions, critical power configurations, and backup systems. Their reputation for outstanding energy efficiency sets them apart, even outperforming flat plate batteries. The unique design of these batteries, with a larger surface area, enhances this superior efficiency. Let's explore some of the key features and benefits of tubular batteries:

  • Tubular batteries store more energy and deliver a higher efficiency due to their expansive, positive plate surface area.
  • Less positive plate shedding prolongs their lifespan, making them last up to 30% longer than flat plate batteries.
  • The Tubular Plate Battery Technology gives tubular batteries the longest battery life and the most configuration options.
  • They offer the highest efficiency per discharge-charge cycle and have a proven reputation for reliability in remote, high-temperature, or unstable power installations.

The efficiency and energy storage differences between SMF and tubular batteries make the latter a popular choice in many applications. Now that we've discussed the efficiency of tubular batteries, let's compare their life cycle with SMF batteries.

Life-cycle Comparison of SMF and Tubular Batteries

In your journey to understanding the life-cycle of SMF and Tubular batteries, considering various factors becomes crucial. You'll learn about the lifespan, maintenance needs, and degradation of both types of batteries. Comparing these two commonly used batteries provides insights into their performance and longevity. Let's proceed to examine these aspects.

Life-cycle of SMF Batteries

With the right care, your SMF battery can typically last three to five years, sometimes even longer. However, you must understand that several factors can influence the lifespan of your battery:

  • Usage patterns
  • Charging habits
  • Environmental conditions
  • Operating temperature
  • Depth of discharge
  • Cut-off voltage set in the equipment

The SMF batteries have a long life cycle because of their maintenance-free design. You don't need to stress about adding water or acid to them. This feature marks a significant difference between SMF and Tubular batteries, adding to their extended life cycle.

The oxygen recombination principle in SMF batteries ensures no water loss during the charge-discharge cycle. This clever feature helps in extending their lifespan.

An SMF battery can handle around 200 charge/discharge cycles at a temperature of 25 degrees Celsius with a 100% depth of discharge.

For example, in inverter systems with high current batteries like 150Ah, a cut-off voltage of less than 10.5 volts can shorten the battery life. But, if you set the cut-off voltage at 11.5 volts, it stops the battery from entering a deep discharge state, thus extending its life.

SMF batteries have a longer cyclic life, which makes up for their initial higher cost. Their efficient operation and extended life cycle make SMF batteries a wise investment. Now, let's move on to the life cycle of tubular batteries that could be of interest to you.

Life-cycle of Tubular Batteries

Tubular batteries, praised for their outstanding lifespan, owe their durability to a unique design. This design includes vertical spines that enhance current transport and reduce voltage loss in the positive plate, slowing the corrosion process.

The active material of the tubular battery's positive plate resides in a non-woven polyester gauntlet. This deliberate design choice helps to prevent plate shedding, significantly extending the lifespan of these batteries, especially during operations when the battery doesn't reach full charge.

Lead-acid tall tubular batteries typically claim a life cycle of around 1500 cycles. However, usage, charging patterns, and environmental conditions can influence this lifespan.

After serving stationary and renewable applications for 4 - 5 years, lead-acid batteries often face a problem: positive plate grid growth. But, the design of tubular batteries cleverly counteracts this issue. Their sliding design absorbs terminal movement due to positive plate expansion, reducing cracks in the case lid and preventing acid leakage.

Considering the design elements, the difference between SMF and tubular batteries becomes clear. Tubular batteries, with their unique design and ability to withstand various conditions, represent endurance in battery technology. As we discuss further about battery options, it's essential to consider their environmental footprint, a topic we will discuss in the following section.

Environmental Impact of SMF and Tubular Batteries

Grasping the environmental consequences of SMF and Tubular batteries is vital. The creation, disposal, and reprocessing stages of these batteries could inflict substantial impacts on our environment. We must examine how these two kinds of batteries influence the environment.

Environmental Impact of SMF Batteries

SMF batteries earn recognition for their efficiency and maintenance-free nature. But have you ever pondered over their ecological footprint? These batteries, thanks to their leak-proof design, shield the environment from possible harm due to water or acid leakage.

Remember, SMF batteries, like other batteries, emit CO2 during their manufacturing process. The growing need for battery materials such as lithium, mined from hard rock mines or underground brine reservoirs, is worth mentioning. They demand more materials for their production compared to traditional combustion engines. A significant chunk of the energy for this extraction and processing comes from fossil fuels, releasing 15 tonnes of CO2 for every tonne of lithium mined. The production process also requires heat within the range of 800 to 1,000 degrees Celsius, most efficiently achieved by burning fossil fuels, contributing to CO2 emissions.

Despite these issues, lithium-ion battery technology, like SMF batteries, turns out to be more climate-friendly when compared to other alternatives. While considering your battery options, consider not only performance and cost-effectiveness but also the broader environmental consequences. Let's delve deeper into this in the context of Tubular batteries.

Environmental Impact of Tubular Batteries

Tubular batteries, compared to numerous other battery technologies, leave a smaller environmental footprint. Their longer lifespan and lower maintenance needs contribute to less waste and a decreased environmental impact. However, Tubular batteries are not without their downsides.

The creation of these batteries leads to CO2 emissions. As the demand for batteries escalates, so does the production of spent batteries.

Now, let's focus on the environmental consequences of disposing of these batteries. The disposal methods for these spent batteries range widely from landfilling to incineration or even complete or partial recycling. The chosen method depends on the quantity of discarded batteries, existing legislation, and accessible infrastructure.

If not disposed of or processed properly, these batteries can lead to severe environmental problems such as:

  • Contamination of soil, water, and air
  • A threat to organisms and human health through leaching, disintegration, and degradation
  • Potential for violent incidents, such as fires and explosions

When weighing the environmental impact of SMF and Tubular batteries, Tubular batteries, despite their impact, provide a longer lifespan and demand less maintenance.

They provide a pure, renewable energy source that needs minimal maintenance and emits no carbon dioxide. Keep reading as we unravel the fascinating world of solar power and shed light on its unique paths in homes and businesses.

Unveiling the Unique Traits of Commercial and Residential Solar Systems

To make an informed decision about renewable energy for your home or business, it is essential to understand several key distinctions. This will help you fully comprehend the differences between commercial and residential solar panels. These distinctions include efficiency, installation, size, and colour. If you are considering installing solar panels on the roof of your commercial structure, consider the following differences:


Commercial solar panels are intended to generate more electricity than residential solar panels. This is accomplished by incorporating a greater number of PV cells in commercial panels. This can be approximately 70 cells or more, whereas only 60-65 cells are found in residential panels. Due to the greater number of cells, the physical dimensions of commercial panels are also greater. This makes it unsuitable for residential use but optimal for commercial applications owing to the ample roof space.


Residential solar panel systems are available in both black and white hues, while commercial systems are predominantly white. Although white solar panels are employed in residential and commercial settings, people installing them for their homes prefer black panels with black backing. In contrast, commercial clients prefer black panels with a white backdrop.

Design considerations for commercial solar energy systems are more complex than those for residential systems. This is because commercial systems are larger in space and have a lot of equipment that operates with higher electrical ratings. These contribute to the technical complexities. In addition, local electrical lines must be evaluated carefully to ensure they can manage the solar input from the commercial solar panel system.


Cost represents a significant distinction between residential and commercial solar systems. The cost of solar panels is determined by the power output rather than the system type. Generally, commercial solar systems have higher initial costs but less expense per watt. Commercial systems are likely more costly per panel than residential systems because of their larger dimensions and greater storage capacity. However, the energy production cost per watt is identical for residential and commercial panels.


Powered by a greater number of cells and larger dimensions, commercial solar panels outperform their residential counterparts in terms of energy output. In addition, commercial solar panels are typically more efficient than residential panels, with approximately 18.6% efficiency.

Broadening the Spectrum of Commercial Solar Alternatives

Businesses investigating solar panel systems possess more options when attempting to go off the grid. Commercial properties may mount solar panel systems on their roof, but they also have the option to explore more innovative solutions, such as solar-panelled parking lots and ground installations. In contrast, residential solar systems frequently have fewer installation options due to limitations caused by home size and neighbourhood restrictions. This restricts their installation only to the roof.

Power fluctuations can pose significant dangers to your electronic devices and computer in the modern world. To protect against these fluctuations and avoid potential damage, backup power supplies, also known as UPSs, are constructed to stabilise the power supply. Different UPS designs offer varying degrees of protection against disturbances such as power surges, noise interference, overvoltage, undervoltage, power decline, and power outages.

Manufacturers have devised a variety of UPS systems, including line-interactive, double/online conversion, and offline/standby configurations, to address these issues. This discussion will concentrate on online and line-interactive UPS layouts, comparing and contrasting them to assist you in selecting the optimal solution for your specific requirements. First, we'll discuss online and line-interactive UPS here.

Line-interactive UPS

A line-interactive UPS maintains the inverter's connection to the electrical grid. In the event of a power disruption, it switches the DC route from the battery through its normal charging mode to its emergency power supply mode. This ingenious setup permanently links the UPS's output to the battery-powered AC inverter. The UPS inverter goes into battery charging mode when the source of input for AC power is stable. When the mains supply goes out, the UPS's transfer switch opens, allowing the battery to provide the device's output. Since an inverter is always wired to the output, it provides additional filtering and results in fewer switching transients.

Pros of a line-interactive UPS include:

  • High dependability
  • Reasonable voltage conditioning
  • Fewer parts
  • Sturdy build
  • High efficiency
  • Less power usage

Negative features are:

  • Unreliable above 5KVA
  • No safety against kinds of power fluctuations
  • Reliance on batteries is necessary for high-voltage distortion zones
  • No frequency regulation or power factor correction

Double/online conversion UPS 

A double-conversion UPS, as the name suggests, does two power conversions: The primary source's Alternating Current (AC) is converted into Direct Current (DC) and stabilized before being supplied into an inverter, which turns the DC back into Alternating Current (AC). In the event of a mains power failure, the UPS will switch to battery power without human intervention. Since the inverter has already been activated, power is transferred to the battery instantly. The double-conversion process reduces power disturbances from the mains, such as harmonics and waveform distortions. Thus, online UPSs offer the highest level of safety for IT hardware.

The advantages of a double/online UPS are:

  • More precise voltage management
  • No interruptions in service
  • Time required to convert direct current to alternating current is minimal
  • Voltage quality is stable if there are no spikes or dips
  • Distortion-free load voltage
  • Highest possible safety from power fluctuations
  • Near-perfect electrical output

The cons include:

  • A huge heat sink for complex designs
  • More power dissipation
  • Reduced UPS efficiency as the inverter is constantly running
  • Increased wattage of the rectifier as it has to power the inverter and the battery charger
  • More expensive than similar UPS options

Comparing Line-Interactive & Double/Online UPSs for Power Backup 

All varieties of UPS systems were created to safeguard hardware and electronic devices in the event of an unanticipated power outage. However, their true potential varies because of differences in their underlying operating principles. Online and line-interactive UPS, provide the same level of protection but in different ways:

Noise/surge filtering

To protect electronics from being harmed by lightning, electromagnetic (EMI/RFI) line noise, and power surges, all UPS systems have surge suppression and line noise filtering features. In particular, the double-conversion functioning of the online UPS unit provides enhanced protection by isolating equipment from facing issues with the alternating current.

Voltage regulation 

Line-interactive UPS can automatically regulate voltage if it falls outside of predetermined ranges. An online UPS achieves greater precision in voltage regulation due to its double-conversion process.

Time required for battery transfer

To ensure the uninterrupted operation of even the most power-sensitive devices, line-interactive UPS systems make the transition to battery power in 2 to 4 milliseconds. Since the inverter will already be powering the linked equipment load in the event of a power failure, there is no transfer time with an online UPS system.

All About the Application of Line-interactive & Double/Online UPS 

Departmental servers, households, SMBs, and MSMEs can all benefit from a line-interactive UPS that provides the high-power reliability they require. These devices use a unique set of operating principles and can be widely used in set-ups ranging from private residences to massive data centers. They require charging the battery either once or twice a day. But, they may require frequent charging in places with poor infrastructure where the alternating current line is unstable, varies dramatically, or is greatly distorted.

The best online UPS system isn't just useful in industries like computing, transportation, securities, banking, medicine, and communications where continuous power is required; it's also the go-to option for providing backup power to essential equipment and servers in data centers. They are particularly used in intensive care units that have very important life-saving medical equipment.

The bottomline

Different types of UPS solutions offer varying degrees of security, so knowing which one you're using is crucial.

Precision Air Conditioning & its IT Applications

The rising temperature in the peak of an Indian summer sets the perfect tone for our blog topic- Precision Air Conditioning for IT applications.

Until recently, data centre managers purchased precision air conditioning systems primarily driven by the need to maintain precise temperature and humidity control in IT spaces. However, ASHRAE (the American Society of Heating, Refrigerating, and Air-Conditioning Engineers) revised and expanded the acceptable temperature and humidity range for sensitive IT environments.

With thermal management for IT systems remaining a critical priority, the requirement for precision air conditioning is a must. What is precision air conditioning all about?Also known as data centre-grade cooling systems, Precision ACs (PAC) like Emerson precision air cooling systems are a special kind of air conditioning equipment that maintain precise temperature and humidity conditions for critical applications such as:

  • Industrial controllers
  • Servers
  • Computer systems
  • Data centre equipment

These exclusive air conditioners are built to maintain temperature and RH in sensitive environments like data centres and IT spaces. Even if precise temperatures and humidity set points are no longer mandatory, the PAC plays a vital role in ensuring data-sensitive devices remain operable even with sophisticated servers' high heat.

What Is The Need for Precision Air Cooling in IT Spaces?

IT is an ever-evolving industry. With automation and digitalisation becoming the norm of the day, enterprises and organisations are making more room to house bigger and more powerful equipment to run their IT network environments. The more powerful the equipment, the more work efficiency it creates. But, this high-end equipment has a big risk: They generate a lot of heat.

Now, imagine an IT network room with these powerful servers connected to more than a dozen computer systems. The equipment-generated heat gets trapped in the space, and without adequate ventilation, the temperature can escalate to dangerous levels that shorten the lifespan of other devices.

Here’s where PACs come into play. These devices allow sensitive IT equipment to remain running and operable and prevent any downtime. Now, you may wonder if commercial air conditioners aren’t good enough to serve the same purpose. Of course, many buildings and industrial facilities rely on conventional AC systems. They are, without a doubt, very effective in controlling room temperature and humidity. Commercial air conditioners and Precision air conditioners serve different purposes. They are also designed differently.
Let’s break down the functional specifications of a precision AC.

4 Specific Functions of Precision Air Conditioners in the IT Environments

1. Manage IT equipment's concentrated heat load

Most IT office spaces are not originally designed to house high heat-generating equipment but have no other option but to do so. High-performance equipment makes conventional cooling solutions ineffective and creates an unsuitable working environment.
Precision air conditioners, however, are specifically designed to handle high heat trapped in small, congested areas and expel it in whatever method the system uses.

2. Operate non-stop, round-the-clock.

Even if the outside temperature is cool and comfortable, IT spaces require air conditioning to remove the trapped heat. Even in such scenarios, you cannot use commercial air conditioning for IT applications because they are designed to operate when the outside temperature is roughly 55 degrees Fahrenheit.

The additional challenge with data grade centre cooling systems is that they will automatically shut down after hours. In such cases, the computer equipment will remain vulnerable to electrical or other issues.

Such problems are uncommon with precision air conditioners, mainly because they are designed to work non-stop, irrespective of the outside temperature. With this feature, you won't have to worry about your computer networks overheating.

3. Air filtration and volume

Compared to a less dense "comfort" application, a high-density heat load in a small space requires more air exchanges. Ordinary air conditioning cannot provide the volume of air needed by IT equipment. Normal office spaces require only two air changes per hour, but an IT room requires multiple changes per hour. This air volume is compulsory to handle temperature fluctuations, hot spots, and ideal heat ratios within the IT environment.

4. Control room temperature to the best of their ability

A conventional AC system’s capacity is split between cooling the space and eliminating moisture from the air. This combination creates a comfortable, optimal temperature when the temperature rises. About 40% of the system’s capacity regulates the humidity in this case. The rest of the capacity, which is 60%, is dedicated to regulating the air temperature and keeping the place cool.

This problem can result in a great deal of waste in IT spaces because IT equipment generates dry, intense heat. This means it doesn't require nearly as much capacity for humidification.

Think about it: What’s the point in buying a 100kW commercial air conditioner to cool an IT load of the same capacity? The system will most definitely fail because system can generate only about 60% of the cooling capacity.

Here’s where PCAs make a difference because they are designed with a heat ratio of 0.90%, which is the optimal cooling capacity required to cool IT devices. The remaining 10% capacity removes humidity entering the room whenever the doors open and close. Nowadays, thermal management systems offer a better heat ratio of 0.95%.

Bringing It All Together

Cooling equipment works best only when they align with the purpose, equipment type and room size. A simple ceiling fan will suffice if you use a single PC or laptop. However, to run an industrial or business server network, you need higher-density equipment requiring a dedicated cooling system like precision ACs.

Industries and corporations have also invested in renewable technologies including wind, biomass, solar, and more out of a need for alternate energy options.

Direct Current power is produced by solar panels by absorbing solar radiation. Direct Current (DC) produced by the solar panels must be changed to Alternating Current (AC) before being utilized by conventional household appliances. That's why there are devices like solar inverters.

Solar Inverters: What is It?

The electricity supplied by solar panels is in the form of direct current (DC), and solar inverters convert this into alternating current (AC) at the proper voltage and frequency. The energy produced by solar inverters may be used either locally in residential infrastructures or sent straight into the commercial power grid for distribution. Selecting the right type of solar inverter is important for optimizing the utility of the produced solar energy.

Types of Solar Inverters Listed Down by Top Inverter Battery Dealers in Chennai

With the rise in popularity of solar systems over the years, it's crucial to understand how they operate and what characteristics set them apart from one another.

The following are the varieties of solar inverters that are most often seen on the market today:

  • On-grid solar inverters
  • Off-grid inverters
  • Micro solar inverters
  • Hybrid solar inverters

It is essential to have a knowledge of the function of an inverter in order to fully understand the distinctions between the four. The primary purpose of an inverter is to convert Direct Current (DC) into Alternating Current (AC). With regards to solar power systems, an inverter is crucial because it controls the flow of electricity to the household appliances. Now that we understand what an inverter does, we can dive into the specifics of the various solar inverter options available.

On-grid or Grid-tied Inverter

In solar power systems, on-grid or grid-tied inverters allow for the extra energy to be sent back into the mains power supply. These arrangements are by far the most common in both households and workplaces. When the electricity goes out, they are expected in a way to immediately switch over to the power backup system and disconnect themselves from the grid. With a maximum conversion efficiency of 98% and low minimum starter voltage, they are ideal for use in a wide variety of applications.

One of the most significant benefits of using an inverter that is connected to the grid is the avoidance of the need for batteries. As an alternative, these setups rely on micro or solar inverters to transform the DC power generated by the panels into AC power. The utility grid is used to store any extra power that is created throughout the process, and the customers are given a credit equal to the quantity of energy that is exported. This method is also called "net metering." Having an on-grid connection has several financial benefits, including net metering, higher efficiency rates, and reduced installation equipment expenses.

On-grid solar inverters also have the benefit of being upgradable. You can simply choose the ideal solar inverter for your requirements from the wide variety of options available. However, if the power goes down, a grid-tied system won't work without a battery backup.

Off-grid Inverter

An off-grid system, although being linked to the utility grid, uses solar power to recharge the battery and power the load. It only draws electricity from the grid when the power generated by the solar panels is insufficient to meet the demands of the load or to charge the battery. An off-grid system relies on two things to function properly: a well-thought-out design and an excellent battery system which can supply energy needs even when there's comparatively less sunlight.

There would be no power on dark or cloudy days if there were no battery or other way to store solar energy. The majority of solar energy storage systems for homes not connected to the power grid are designed to charge during the day and discharge at night. These systems may be customized to generate enough electricity throughout the day to meet the demands of a household.

One major drawback of using an off-grid solar inverter is that, if there's gloomy weather for many days, solar power alone may not be enough to meet electrical needs. They are adaptable and may be utilized in any situation. Nevertheless, a battery is required for an off-grid solar inverter to operate.

Micro Solar Inverters/High-Efficiency Dual MPPT Inverter

When it comes to solar inverters, micro inverters are among the most well-liked. This Solar Power System's solar inverters are hardwired to each individual solar panel. They provide a simple plug and play setup and eliminate the need for complicated wiring, making installation a breeze.

Installing solar panels requires a connection to your home's electrical grid, just like any other source of electricity. The drawback of a typical string inverter is that it limits the amount of power that the solar system may generate to that of the least efficient panel. As one panel fails, the others follow suit. Nevertheless, a tiny inverter is set up between each solar panel and the roof. Each solar panel may generate up to its maximum output since each panel comes with its own micro inverter. This means that a micro inverter is more efficient and effective than the traditional string inverters.

Every panel gets the most power possible since there is no weak link in the microinverter system. Also, it makes you safer. As they prevent high-voltage DC from being sent onto the roof, solar panel micro inverters are a more secure option.

Hybrid solar systems

Hybrid solar systems are grid-connected setups that use battery backup. These solar systems may be put together in a variety of different combinations. This solar system collects sunlight throughout the day to use power after the sun goes down. The solar system draws power from the grid and has the capacity to store surplus energy. Batteries may be charged in hybrid systems utilizing less expensive off-peak power. The cost of hybrid systems is much higher than that of standalone or off-grid systems.

Despite their high initial cost, hybrid systems provide users the benefits of both net metering and energy storage in the event of a grid outage. Customers benefit greatly from a constant flow of electricity from a hybrid solar system. Moreover, hybrid systems need significantly less upkeep than traditional diesel-fueled generators.
