Uninterruptible Power Supply Systems (UPS Systems) perform backup and conditioning roles for the systems they are connected to. They are very important in situations where primary power supplies fail or other power supply problems, such as spikes, brownouts, electrical noise, sags, or surges. UPS systems protect small business applications used for communication, entertainment, or security from electrical surges or sags and prevent business disruption, data loss, or even injuries and fatalities.
In this article, we’ll tell you all about UPS Systems and have you choose the best UPS type suited to your business.
The UPS is a battery backup system that can perform many important functions in a set-up that depends on a primary power supply. Its main role is to act as a secondary power supply that will run long enough to shut systems down properly and back up data sufficiently when an unexpected power outage occurs. The UPS also performs an important surge-protector function to keep devices safe from the harmful effects of abnormal voltages and surges, including reduced performance or lifespan of the device. So it saves the company a world of pain when it prevents data loss and device stress or damage by preventing forced shutdown during an unforeseen power outage.
An acid or lead battery inside the UPS system provides the backup power required when its sensors detect that the main power supply has suddenly shut down. This backup power will not be available for an extended period, but it allows operators to save or back up any critical data and shut the system down gradually or function until the power supply is back on.
UPS Systems are of three main types - the line interactive system, the standby system, and the online system. Other types exist, but they are usually hybrid combinations of two or multiple main UPS system types.
Let’s discuss these system types in more detail:
1. The Line Interactive UPS System
This system serves a dual purpose as a backup power source and a power conditioner. It is the optimum system type if your devices function in an environment with rare power outages but frequent fluctuations. The system can adeptly handle several ranges of fluctuation episodes before switching on its battery power backup. This benefit of handling wide ranges of fluctuations and the circuitry for voltage boosting is a critical one. In fact, wider ranges of accepted fluctuation in the system will give you more overall protection for your devices.
2. The Standby UPS System
The Standby system earned its name from its basic function of acting as a standby when there is a sudden power outage. It performs conditioning for minor surges and usually draws power from the main AC source during normal functioning. The system is also provided with an AC/DC inverter that kicks in when sensors detect trouble in the main power source. But this system has a small transfer time drawback that users should be aware of.
3. The Online UPS System
The online UPS system, also called the double conversion system, performs by isolating the device load from the main power grid. It achieves this by following an AC/DC DC/AC double switch. The online UPS system converts the incoming supply of main power to DC and then back to AC, effectively isolating the load from the rest of the grid.
This switching function is possible because of the rectifier device in the system, which receives incoming power, converts it to DC, and feeds it into the inbuilt battery and onto the connected device through an inverter. This system nullifies the need for power transfer switches. In a power outage, the rectifier drops its connection with the main grid and uses the battery energy to power the connected device until the main power is restored.
Four main factors should determine your choice of UPS systems for your devices. These are discussed at length below:
1. Determine common power problems.
Power blackouts are the most common power problems people are aware of. But when electronic devices and critical equipment are involved, you will need to be aware of the following:
If your business is operating in an area that faces blackouts, brownouts and surges but none of the other power anomalies, a standby UPS system could work well for you. An online UPS system may be required if you face a combination of all the above power problems.
2. Select the right size.
The optimal UPS system for your business will have to be sized correctly in terms of capacity. Depending on how much equipment will need the supported power supply and the combined load or amount of power they will use, you can choose a UPS with a comparable load capacity. You can find information about capacity and load in the corresponding user manuals of your devices and the UPS system you are considering. Manufacturers or other professionals could also help you make the right connections to match device load to UPS capacity.
3. Determine optimum run time.
Runtime is the next important consideration for choosing the right UPS system. Runtime is the amount of performance time your system requires to provide alternate power when there is a power outage or other trouble in the main supply. Calculate how much time you will need to perform a safe system shutdown and data backup, and this can be used as runtime. System load or the amount of power load your system needs to back up has an effect on runtime. A larger load will mean less runtime or battery life, and vice versa.
Think in ranges when determining optimum runtime. Work from the least amount of time you will need to optimise your devices and work up from there. A broader range of runtime will give you more choice in UPS systems.
4. Choosing an appropriate form factor.
There are three main form factors or size and shape of the device housing. These are:
In short, form factor choice is usually determined by where you want to place your system.
Conclusion
UPS systems are not everyday buys. They are high-priced investments that must be carefully considered and matched to your needs. At the same time, they are necessary in most cases and are invaluable for protecting your devices and company data. If you are looking for professional, experienced UPS dealers in Chennai, our Nantech services will be just the right fit for you!
All businesses have one main goal- Providing the best customer experience. This is true even if you want to set up an EV charging station. Wondering what an EV charging station has to do with customer experience? Well, here's a fact: Charging EVs takes time. We are talking about a minimum of thirty minutes to get at least 80% charge.
Longer charging times mean longer dwell times for customers. To make their charging experience worth the time and money, you need to spruce up your charging station with adequate amenities and services.
EV charging is unlike refuelling your car or bike, where you fill it, shut it, and forget it. And let's not forget that even fuel stations nowadays sport coffee shops and mini stores for their customer's benefit. No one's complaining about having a quick cuppa or a packet of chips after filling their gas tanks, are they?
The reason for having amenities in a charging station is more profound with EVs. An EV's charging capacity depends on:
Sometimes, even the weather determines how an EV's battery remains charged. Besides, once a battery is 80% charged, the charging speed slows down to prevent the battery from being damaged. However, an EV with 80% charge is good to go for hundreds of miles.
So, let's say a customer drives into your EV station to charge their car. Their dwell time will range from at least 15 to 60 minutes, even if you have an ultra-modern charging facility. What will your customers do while waiting for their vehicles to charge? Having all the potential services, amenities, and merchandise within their reach will improve their charging experience and give them a reason to return to your station.
This is also a great strategy to improve business and encourage people to opt for EVs.
So, let's check out the various amenities your EV charging station can have.
1. Restrooms
A restroom is the most basic convenience businesses must provide for their customers. Once their vehicles are plugged in, the next thing they may want to do is answer nature's call. A restroom is a must, especially if your station is located on a remote highway or away from the city or town.
2. Lounge area
Having high-volume charging traffic is the key to justifying lounges. From a business perspective, a well-equipped lounge with ample conveniences such as clean bathrooms, WiFi, workstations and a coffee bar could be a valuable money-making factor. Moreover, these lounges would be useful for drivers of ride-sharing services at airports and other high-traffic areas.
3. Food service
Remember that at least 70% of the travellers who stop to charge their EVs wouldn't mind grabbing a quick bite to eat. It would not be a problem for customers to order a sandwich, burger, or burrito for the same amount of time it would take for the car to charge. And let's not forget the number of customers a coffee shop would attract just by having EV charging points in their parking lot.
However, this concept would only make sense if your station has at least a hundred charging stations.
Another ideal scenario that may work for you (especially if you are short-staffed) is to install vending machines. You can also opt for third-party vending machine services for refilling and maintenance.
4. Shops
There's a high possibility for EV owners to make a purchase while refuelling their cars. Think of it- There's no better way to kill time than to browse the aisle of a well-stocked convenience store, grab a few knick-knacks or stock up on the potato chips for kids. This incredible business strategy works both ways: You can install EV charging points at your convenience store or vice versa.
5. Entertainment
Install a wide-screen LED TV and set up a dozen comfy-looking chairs, and you will have a room full of EV owners catching up on the news or watching a cricket match while waiting for their vehicles to charge. A TV will also give weary children some respite from a long day's travel.
6. Air for tyres
Today, almost every fuel pumps have air-filling stations because it has become more of a necessity than a luxury. Besides, most stations offer this amenity completely free of cost. Hence, installing an air-filling station along with the charging outlets only makes sense.
7. Maintenance services
Generally, EVs require very little maintenance. However, you could think about investing in a small maintenance workshop, especially when business picks up and your centre starts attracting more vehicles. You can offer quick or emergency services like:
Other services like car wash or self-service vacuum options can also be considered.
8. WiFi connection
Providing WiFi networks to incoming customers is a fast-catching trend. Not everyone will want to watch TV or spend time at your convenience store. You will have customers who would rather spend their time being productive at work. A strong WiFi connection in your lounge could prove immensely useful for customers willing to pay for the service.
A long charging time is an excellent opportunity to provide facilities that add value to your customer's experience at your charging station.

Have you ever considered the wiring and internal components when buying a voltage stabiliser to safeguard your home appliances? Likely not. Most of us overlook these important details.
In the case of a voltage stabiliser, the winding material is the most important component that plays a major role in how the device works. The winding material comes in two choices- Aluminium and Copper. Now comes the million-dollar question: "Which material is better- Aluminium or Copper?"
This blog analyses the differences and the functionalities of both materials to make it easier to pick the right choice. But first things first...
Most appliances in your home or office function with the solid support rendered by the voltage stabiliser. It is an appliance that keeps the flow of voltage-current stable and protects your devices from voltage fluctuations and erratic power supply.
Let's say there is a sudden, unexpected drop in the incoming voltage. Your stabiliser jumps into action, activating the electromagnetic relays. These relays, in turn, add extra electricity to the secondary winding and compensate for the voltage drop. Similarly, if there is a sudden increase in voltage, less electricity is relayed to the secondary winding to stabilise the output voltage.
So, essentially, the winding material is the "heart of the stabiliser," without which the device cannot work. Industry experts say that copper has the upper hand compared to aluminium, although manufacturers widely use both materials. What makes copper superior to aluminium? Why is it the preferred choice? Let's find the answers in the following discussion.
1. Thermal Connectivity
Copper has the upper hand in thermal conductivity, especially when it comes to reducing the hot-spot temperature rise in transformer windings. However, this superiority is achievable only when both windings are similar in size, geometry, and design.
It is also possible for aluminium to achieve the same thermal conductivity characteristics by making the aluminium coil 66% larger in its cross-sectional area. However, whatever the winding material, stabiliser manufacturers conduct several tests to produce acceptable hot-spot gradients. They:
2. Current distribution
Copper's higher metallurgical properties make it a better distributor of electricity when compared to aluminium. Copper winding enables an even, reliable, and stable current distribution than aluminium winding.
3. Terminations
One problem with aluminium stabilisers is the formation of oxide, which does not enable easy detachment from terminations. Here again, copper reigns supreme because they are soft and easily detachable. This makes copper stabilisers more durable than their aluminium counterparts.
4. Galvanic action
Galvanic action occurs between two electromagnetically different metals in contact to create a conductive path for ions and electrons to move from one metal to another. Galvanic actions sometimes result in complete loss or partial loosening of contacts. In this scenario, aluminium stabilisers lose more material through galvanic action than copper stabilisers.
5. Creep Level
Under extreme loads or high temperatures, aluminium stabilisers are more susceptible to failure than copper stabilisers because the creep rate of aluminium can reach 25 times.
6. Connectivity & Performance
Due to lower energy losses, copper stabilisers perform better and are more efficient than aluminium stabilisers. Moreover, copper is more conductive than aluminium due to oxides, chlorides, and sulfides. Aluminium connections are susceptible to corrosion, so it is more important to clean and protect their joints. Also, the connections between aluminium transformers and copper building wire are not very dependable.
7. Strength and flexibility
Without a doubt, aluminium is a strong and flexible metal. But here again, copper is far superior in both aspects. Therefore, stabilisers with copper winding require fewer inspections and maintenance procedures when compared to those with aluminium winding.
8. Manufacturing expenses
Although copper is expensive, copper stabilisers require less material and cross-sections of the conductor. Therefore, it costs less to manufacture copper stabilisers than an aluminium ones. Furthermore, copper stabilisers are more viable because they require:
These are some of the reasons why stabiliser manufacturers prefer copper over aluminium.
The winner is copper all the way! Aluminium is good, but copper is the best because it has:
Other reasons why copper is highly recommended:
An aluminium wound coil requires approximately 1.8 times as much cross-section to carry the same current as copper. More cross-section means more manufacturing costs.
Compared to copper, aluminium has a potential threat, which is its reaction with oxygen in the air, causing it to overheat and burst into flames.
Transformers with a higher copper content typically have higher energy performance and lower lifecycle costs.
We have stated enough reasons to justify why copper-wounded stabilisers are far better than aluminium-wounded stabilisers. However, in reality, aluminium stabilisers quickly gain acceptance because of the cost advantage.
Yes, copper is expensive, and that is one of the reasons why manufacturers prefer aluminium. However, awareness of copper stabilisers and their benefits will enable consumers to see beyond the price point and make the right choice.

Solar panels are gaining popularity among the masses for their sustainability and eco-friendliness. As efforts to reduce the environmental damage continue to increase, solar panels and other sustainable forms of energy are gaining a wider consumer base as a cheaper and more efficient fuel than coal and other fossil fuels. In this article, we take a closer look at solar panels and ways to use and maintain them efficiently.
Solar panels and solar power gain over other non-sustainable forms of energy in three important ways. They are:
It is now common knowledge that energy consumption methods commonly practised in homes and businesses generate large amounts of hazardous waste. This affects the environment at many levels. The use of solar panels eliminates this pollution by storing and using the sun's energy to power common household appliances like lights and heaters. Here's how the use of solar panels can be beneficial to the environment.
Using solar panels reduces:
Using solar panels can help reduce our dependence on energy sources that produce hazardous chemical wastes like oil sludge and coal ash which increases the presence of metal compounds in the environment to dangerous levels.
It is now commonly known that traditional methods of electricity production have had devastating effects on the environment. Power plants that generate electricity release dangerous toxins like carbon dioxide, nitrogen dioxide, mercury and particulate dust. This has led to phenomena like global warming and climate change, contaminated fisheries, acid rains and smog.
The use of solar panels can reduce our dependence on such toxic power sources. Even limited use of power panels energised by the sun can significantly impact total energy production and consumption.
Water bodies have also suffered tremendously from pollution because of our dependence on coal-based power plants. They release toxins like arsenic, boron, selenium, mercury and cadmium into water bodies, effectively poisoning them. Release of large amounts of warm, low-oxygenated water into water sources has only added to the damage. The adoption of solar energy can reduce our dependence on these dangerous, unsustainable sources of energy, and also give the environment a chance to recover from the damage.
Coal-based power plants raise the need for surface mining, bringing profound environmental challenges to the forefront, even before coal-based energy is produced. The energy produced by solar panels can eliminate the need for coal-based energy, thus cutting down on the impact on the environment.
Solar panels are fundamentally durable and sustainable sources of energy. They can withstand adverse weather conditions. But we can take a few steps to maximise their life and protect them from unnecessary damage. Here are seven simple ways to protect your solar panels:
Periodic cleaning is necessary to maintain the optimal functioning of solar panels. Washing down with a hose pipe needs to be supplemented with a thorough scrubbing with a soft rag or sponge. Experts recommend using the rag or sponge attached to a pole from the ground level.
Falling trees are not the only things that can damage solar cells. Branches, leaves and twigs that fall continuously can scratch the surface of the cells and reduce their efficiency. This will lead to a need to replace the cells, which can be expensive.
The sealants on the solar panels can wear with time. This will affect their functioning since water and dust can seep through the gaps into the PV mechanism and cause short-circuiting. Faded sealants can be repaired, preferably with a silicon-based sealant that is effective and easy to use. Regular inspection will help you identify areas that need repair. Major wear and tear in significant places like the area between the roof and panels will have to be replaced.
Natural disasters and similar occurrences cannot be prevented. But there are measures one can take to control the damage. Many businesses and homeowners install lightning rods to protect solar cells from lightning strikes. Even indirect strikes can cause a power surge that can harm the panels and people.
Installing solar panels requires proper grounding for protection and proper functioning. Anchoring is also an important step in proper solar panel installation. As the name suggests, anchors are tools that hold the solar panels in place, even in the roughest weather. Panels that are mounted in the ground require proper earth-anchors to withstand any weather.
Natural disturbances to the smooth functioning of the solar panels can come in many forms:
It is recommended that you instal mesh wiring and other protective measures to prevent such damage.
Retaining walls are supporting structures made of pre-cast concrete, which can form an impenetrable support against weather and climatic conditions like rains and storms. These can last for decades and work to strengthen the foundation on which the panels rest. They will be a good investment if you live in places that receive large amounts of rainfall or experience other adverse weather conditions.
Solar panels are considered permanent fixtures when installed on the roof. They can be insured against damage due to fire or water and theft or vandalism. Many companies also provide insurance for accidental damage.
There are many advantages to investing in solar energy. It is one of the most beneficial sources of power - it is endlessly sustainable, cost-effective, and energy-efficient. There are long-term benefits to the environment and ultimately to your health and well-being as well.
For all these reasons, it will be wise to invest in solar panels for energy production in your home. For maximum benefit, follow the tips discussed above to enjoy the benefits of solar panels for many years to come. Professional UPS manufacturers like Nantech Power Systems in Chennai can be of great help for best-fit recommendations and installation.
Every individual in the entire world today is connected through the internet. Continuous technological innovations are bringing the world closer and closer. Power is the basis to keep this technological development working. Therefore, it is important to address the power failure issue with a suitable inverter. We have consolidated all the information that one should know before reaching out to a professional inverter battery manufacturer like Nantech power systems in Chennai. Keep reading about the various types of inverters, how they work, and aftercare procedures.
Inverters turn on various electrical devices even when the main supply is switched off. During power failure, they are emergency backups and convert direct current (DC) to alternating current (AC). The DC or direct current is created from either a solar panel or battery, which is converted into a 110/220 V alternating current and supplied to electrical appliances. DC is converted to AC because direct current can't travel for long distances. Every electrical equipment in a building will run on an AC current from the main power supply. Another advantage of AC is that it can experience both rise and fall and change its direction periodically, whereas DC can flow only in one direction. The voltage also reverses periodically in an AC circuit whenever the current changes direction.
How do Inverters Work?
Inverters store electricity in the form of DC in their batteries. When the power fails, the inverter starts to convert the DC to AC by passing it through a transformer. The change in voltage output instantly happens to resume the supply of electricity. Thus, as the direct current passes in an inverter, a series of switches turn on and off continuously and start stepping up with the help of a transformer. Then the switches alternate the DC signal's direction to create a sustainable AC voltage. Eventually, the electrical appliances gain a power supply even when the main power is shutdown.
Types of Inverters
Type of Load
Inverters are classified based on the output waveform and the load. Based on the type of load, the two main types of inverters are:
Type of Output Waveform
Depending on the output waveform, there are three classifications in inverters. They are:
The battery is the workhouse and backbone of an inverter. The life, performance, and efficiency of an inverter solely depend on the quality of the battery. The battery is the heart of the entire inverter system to determine the backup time. A good quality battery will offer the best solution during power failure and ensure low maintenance along with high reliability. There are three types of batteries used in an inverter, and they differ based on the technology to store the current. By knowing them in detail, you will be able to choose the right one for your usage.
Flat Plate Battery
Flat plate batteries have two electrodes and are commonly referred to as lead-acid batteries. The electrodes are immersed in water and sulphuric acid, an electrolytic solution. The positive electrode contains a lead oxide, whereas the negative electrode is made of porous lead. Flat plate batteries are lightweight and cost between nine to fifteen thousand Indian rupees. These batteries need regular maintenance, which is a major disadvantage. Therefore, tubular batteries have replaced flat plate batteries in recent times.
Tubular Battery
Tubular batteries are seen to last for a longer duration than flat plate batteries. They have a life of five years and are very efficient with less maintenance. The deep charging cycles enable these batteries to perform with greater efficiency. Tubular batteries need fewer water top -ups and are more reliable compared to the flat plate battery. However, tubular batteries cost more than flat plate batteries and are available between nine to twenty-five thousand Indian rupees.
Sealed Maintenance-Free Battery
A sealed maintenance-free battery is also known as valve regulated lead acid battery or VRLA. The reason why many prefer a VRLA battery is that it requires no maintenance. There is no need to replenish the electrodes with distilled water, and they are very safe for usage as they do not give out obnoxious gases. But the sealed maintenance-free battery is very expensive compared to tubular and flat plate batteries. The disadvantage of these batteries is that they have a shorter life.
If you are confused about choosing the right inverter, the points mentioned below will help.
The Bottom-line
With the above details, you would have understood all that you need to know about inverters. Now you can easily purchase the right one that suits your requirements and demands. However, make an effort to identify the inverter that will be perfect for daily usage and carefully look into its maintenance criteria before purchasing. Reach out to Nantech Power Systems, the pioneers in manufacturing inverters for commercial and domestic usage. We are the only inverter battery manufacturer in Chennai to deliver products with extended maintenance-free services.
Facing a power quality issue? Get yourself an Active Harmonic Filter and reduce harmonic pollution during electrical installation. Using an active harmonic filter ensures that the current is "clean". An active harmonic filter requires a stable external power source to inject phase opposite current harmonics to downstream loads. Depending on the stability of the connected external power source, its efficiency will vary.
In this blog, we analyze the pros and cons of harmonics. But first, let's see what leads to harmonics in the power system.
Technically speaking, when the current waveform deviates from the sinewave shape, it is said to contain "harmonics." Is that a good or bad sign? Apparently, harmonics is a bad sign because harmonic frequencies in the power grid cause power quality issues. Why do harmonics occur? Leading inverter battery manufacturers and suppliers from Nantech Power Systems Pvt Ltd, Chennai, point out two things:
Blame 1: Non-linear loads
Power distribution circuits use non-linear devices that create non-linear currents and cause voltage distortions. Some common examples are:
"Harmonic current" is a term commonly used to describe these non-linear currents and voltages. A high load on the power distribution network leads to harmonic currents, which are multiples of the fundamental frequencies.
Blame 2: Electronic switching devices
The excessive use of electronic switching devices in modern equipment has significantly increased the harmonic pollution in the electrical distribution system. Some of the common examples are:
To rectify these power issues, we need one main aspect: Harmonic filters to harmonics coming from the power distribution network. These filters use "frequency conversion technology" to control harmonics and improve power quality in two ways:
With the availability of passive filters, why do experts lean towards active harmonic filters to rectify harmonics in power generation? The reasons are obvious. These filters come equipped with an additional amplifier that changes their action and improves stability. An active filter also:
However, these above-mentioned factors are just the tip of the iceberg. In our next section, we have explained more remarkable advantages in great detail.
Also Read: Why Choose Active Harmonic Filters Over Passive Harmonic Filters?
1. Prevent equipment failure and breakdowns.
When many small harmonic-producing devices are collectively causing large amounts of harmonic pollution, filtering the main power supply is a very useful solution. Active harmonic filters effectively prevent failures and breakdowns of devices since they help correct non-linear loads. The filters also provide energy efficiency, which helps extend the durability of the device.
2. Help in maximum use of installed capacity.
An ideal example of active harmonic filters maximizing installation capacity is their use in the AC lines parallel to the loads that produce offending harmonics. The active harmonic filters inject inverted current into the AC lines and cancel harmonics, improving electrical stability.
3. Improve energy efficiency.
One of the best aspects of active harmonic filters is that they are scalable and sized to the harmonic current for multiple loads. You can also install additional units if the total harmonic current exceeds the rating of the single harmonic filter. They also decrease the emission of carbon dioxide.
4. Reliable and provide continuity.
Active Harmonic Filters are handy for areas with significant non-linear loads and many DC drives because they reduce production disruptions. Therefore, these filters also extend the device's life, enabling them to perform consistently well.
5. Curb service and maintenance costs.
Any electrical device that operates at maximum efficiency is bound to work without issues. This theory is applicable for devices with active harmonic filters. Unless the capacitors and resistors are required, the active harmonic filter does not require custom fabrication because it is largely impedance-independent. According to the manufacturers, active harmonic filters can handle wideband harmonic frequencies to minimize service costs.
6. Prevent and reduce energy loss.
Harmonic pollution is synonymous with energy loss because it affects electrical installations' reliability, safety, and efficiency. An active harmonic filter installed on the main power supply can counteract all harmonic currents before reaching the transformer. They also reduce the absorption of reactive power and reduce wear and tear, thereby preventing energy loss.
7. Reduce fire risks.
Harmonic frequencies can increase heating in equipment and conductors. However, with active harmonic filters, you can:
Active harmonic filters are a sure-fire way to reduce fire risks due to overheating.
If you decide to use active harmonic filters, you should also know their shortcomings. Experts say these filters:
The Takeaway
The demand for active harmonic filters is at an all-time high, thanks to the widespread proliferation of non-linear loads. They have become almost indispensable for large power installations, with electric arc furnaces, induction equipment, and electric furnaces. Yes, the active harmonic filter is here to stay!

The wind, water, and sun are the three big players of Green Energy. Of the three, solar energy has grabbed global attention as an effective solution to reduce energy consumption and environmental damage.
The global shift is driven by government initiatives and a massive adoption of solar lighting systems like solar street lights. Why solar street lights? The answer is obvious. The entire world is focussing on sustainable power sources to curtail greenhouse emissions. The relentless pursuit of green power drives the need and the market growth for solar street lights. Here's the proof: Global experts say that the market for solar street lighting will reach $14billion by 2027, with a post-Covid CAGR of 14.7%.
In India, solar street lights are a common sight. Thousands of them dot the highways that criss-cross the length and breadth of the country. As dawn turns to dusk, these solar street lights come alive and flood the highways with clean, sustainable power.
Standalone solar street lights are fast gaining power for some good reasons. They are:
Rather than relying upon on-grid power supply, solar street lights rely on batteries or photovoltaic cells for solar energy storage. This aspect makes solar street lights a feasible option to power highways and roads in remote places without any power grid source. These systems can also use the stored energy by converting it into electricity as per the requirement. For your solar street lights to function well, they must be exposed to direct sunlight, allowing them to soak up the solar energy for at least eight hours. Once charged, they are good to go for the rest of the night.
If you are looking to invest in solar street lights, it is undoubtedly a wise decision because these solar-powered solutions are fast gaining traction. The popularity of these street lights is driving the market and vice versa. The solar lighting market is flooded with dozens of options that could be overwhelming for inexperienced investors. If you are not well-informed, you may buy low-quality solar street lamps manufactured with sub-par materials.
However, our blog is packed with all the information you need to consider when investing in solar street lights. Let's read on.
When make enquiries about solar street light dealers in Chennai for solar-powered lamp sources, they come up with several options like:
Of these choices, the best option that's a close replica of the sun's spectrum is the LED light. Nowadays, smart solar-powered LED lights are powered by higher lumens that use less energy. Furthermore, LED lights make solar power integration simple and easy. So, they could be the better choice.
All solar lights are powered by batteries, which are available in two types:
Of the two, lithium batteries are better because they have:
It is important to note that the battery capacity should meet the lighting efficiency requirement. If not, the street lamp will not provide adequate lighting during the rainy season.
When you are at a latitude greater than 15 degrees, the sun's inclination angle with the ground is greater than 15 degrees. Therefore, you must consider solar street lights with adjustable solar panels. Also, the panels of solar street lights installed on both sides of the road should not face away from the sun.
The heat dissipation is another important factor determining the LED lamp's quality. Basically, heat dissipation is nothing more than the transfer of heat. However, dissipation also refers to heat loss driven by undesirable effects. Therefore, every time the heat dissipation is inadequate, the lifespan of the semiconductor device in the street lamp is shortened. It is better to choose anti-ultraviolet and fireproof LED lights to ensure adequate heat dissipation.
When considering solar street lights, look for details about the footcandles as they determine the illumination on the floor. Ideally, the bright/dark ratio should be 4:1, but a minimum ratio of 3:1 is also good. You should also consider the colour temperature, measured in degrees Kelvin.
It is better to opt for light coloured lamps since black coloured lamps are highly heat absorbing. If the lamp is black, the temperature of the metal shell can reach up to 90 degrees Celsius underexposure. The high temperature will destroy the battery and the LED light source. Therefore, choose a silver shell that will not absorb heat or fade when placed outdoors.
Charging and discharging controllers are also known as solar controllers, and they coordinate the work of solar panels, storage batteries, and loads. An effective heat dissipation function is crucial for selecting a controller. Another essential feature is temperature compensation. A smart controller has been added to prevent overcharging and undercharging of solar batteries. You would be better off investing in a smart solar controller with built-in communication that allows real-time monitoring and control of the system. The controller would offer maximum performance and longevity.
The sensors are of two types:
The PIR or the Passive Infrared Sensor is included in many solar street lights to help conserve energy. The sensors work by measuring infrared light allowing the sensor to detect movement.
The solar controller coordinates the work of the panels, loads, and batteries. Hence it is essential to pick a controller which gives you the following benefits:
The solar panel is the main component of the solar street lighting system. To determine the quality of the solar panels, you should:
Solar street lamps are certainly a big investment. Hence you need to ensure the manufacturer offers an extended warranty period of 20 to 25 years. Also, look for reputable solar street light dealers that offer good after-sales services.
In this model, the solar panels are attached to the poles. This panel positioning is slightly disadvantageous because the sunlight effect is minimal, and the absorption effect is only one-fifth of the ordinary solar lights. Moreover, the absorption rate is almost nil when the sun is directly above.
The conversion equipment is different in this model because the conversion mechanisms are different. If wind energy is used to charge the battery, it will cause decay and affect the battery life. Hence, this model may not be the right choice if you are looking for solar lights that will last a long time.
Nantech Power Systems Pvt Ltd are one of the most recognized solar street light dealers in Chennai. We have years of experience dealing with off-grid and on-grid solar power plants and street light installations. Want to power up your locality? Call us today.
The recent Union Budget 2022 rolled out the blueprint for India's 100th year. And the main focus was economic development. To do that, one of the notable suggestions was to give emphasis on creating infrastructure for the mass adoption of electric vehicles. Our Finance Minister, Nirmala Sitharaman, announced the Battery Swapping Policy. This policy is aimed at making EV's more accessible to the public by making them more affordable.
Any discussion about EV is never complete without discussing EV charging solutions. These vehicles will need charging plug points in all public places so that they can be charged easily and quickly. These charging stations are usually designed to dispatch DC or AC power (Direct Current, Alternating Current). The DC charging infrastructure is approximately 5X times quicker than the AC charging infrastructure. And, that makes the cost difference 100X times.
This disparity clearly indicates that DC charging stations will scale much slower than the AC charging stations. And that further turns our attention to the fact that India needs a more reliable alternate method to charge their electric vehicles.
Now, battery swapping makes a grand entry here. The concept of battery swapping is simple- any user can quickly replace a discharged battery with a new, fully-charged battery within a matter of minutes. It will be far easier than a trip to the nearest petrol bunk. IoT (Internet of Things) will check the battery's charge and offer the right guidance as to which battery to select at the swapping station. Thus you can ensure that the battery is completely charged and not just partially charged. Now that you know what battery swapping is, let us now take a look at the battery swapping policy announced by our Finance Minister!
During the Budget speech of Nirmala Sitharaman, she mentioned that "considering the constraint space in urban areas for setting up (electric vehicles) charging stations, a battery swapping policy will be brought out and interoperability standards will be formulated."
So, what are the key points we can derive from it?
India lacks the presence of easy to access EV charging stations in public places. We do not have the infrastructure to support it. This makes EV's an unattractive option for people who are looking for convenient solutions. In such a situation, battery swapping stations are a great alternative. It requires less space and can be easily incorporated into our existing infrastructure. EV owners can quickly swap the drained batteries of their EV and swap them with fully charged batteries.
The Battery Swapping Policy has also made it clear about establishing standards of interoperability. This will further make battery swapping easier for EV owners as any EV battery can be used in any EV brand. It simply means that the battery used in brand A can also be used in brand B and vice versa.
As a direct after-effect of the policy, there will be an increased investment by both new and existing EV manufacturers. Manufacturers will now focus more on improving the efficiency level of batteries and introducing embedded technologies. The set standards will be equally beneficial for EV owners as well. They will now get to choose between various competitive EV brands.
If you analyse the costs involved in an electric vehicle, the battery cost is a major contributor. The cost of materials involved in developing the battery and technologies administered to make it efficient makes the overall cost of EV go higher and higher. Now, with the introduction of battery swapping, we can remove the battery part from EV as a separate purchase. This will make the cost of EV drop significantly. Though you will still have to buy a battery for your EV, the reduced upfront cost will make EV's more affordable for one and all. Interested to know more about EV?

With unreliable grid power supply being the norm of the day, most businesses and industries have equipped themselves with generators or UPS. Some of them are clever enough to invest in both to ensure a reliable chain of power 24/7.
The world stands divided over which power solution is better- the Uninterrupted Power Supply (UPS) or the generator. As one of the leading UPS manufacturers, we at Nantech, Chennai, suggest combining the best of both worlds. UPS and generators are both essential parts of any power infrastructure. When integrated, they provide you with a seamless, highly-effective, and safe power solution for your business.
In this blog, we've explained everything you need to do to gain the combined power of your UPS and generator. But here's a small intro about both power sources before we venture into the details.
Popularly called the UPS, the Uninterruptible Power Supply is an electrical apparatus that provides backup power when the main power supply is compromised. From powering a small household to running your entire computer system, the UPS is the top choice for many people.
The device contains batteries that automatically detect any loss of power and kick in to fill the gap within seconds or minutes. This results in assured continuity and functionality of your electric devices. Additionally, the UPS also safeguards your devices from unexpected power surges.
The backup generator can come in sizes as small as a suitcase or as large as a house. This self-powered device can generate electricity by converting mechanical power into electrical power. As per their capacity, generators can provide power for a longer period and effortlessly run heavy appliances.
Despite their differences in design and function, UPSs and generators are the most reliable solutions for uninterrupted power supply. Technology has simplified the way businesses operate and ease our reliance on electricity. Hence, it is easy to understand the outcome if these devices are used as a combination rather than stand-alone solutions.
If you plan to invest in both the UPS and generator, you need to know what to do to optimise these solutions and gain the most from them. Here are our guidelines.
The concept behind the UPS-generator combo is to use the UPS running as long as possible and then switch to the generator power. The generator will supply the power until the main supply is restored or until the system is properly shut down. Generators and UPS can work in perfect harmony as long as you implement these best practices.
Always assess your generator frequency when using the UPS-generator combo. Here's why:
If the UPS' input voltage and frequency exceed the set level, the UPS will slip into the battery mode. When connected to the generator, the UPS may consider a generator an unstable power source if its frequency range is too wide. As a result, the UPS will run permanently on the battery, resulting in the battery failing and dropping your load.
List the electrical devices you want your generator to power. This list includes the AC, lighting, computer systems, and other vital services. Now, assess if your generator can power these devices. If your generator isn't large enough, it will not be able to hold voltage and frequency within input tolerances.
Therefore, if you aim for potential growth with a generator-friendly UPS, it is wise to size up your generator whenever your budget allows it.
There are three fuel options to get your generator up and running:
Assess their pros and cons and choose the option that works best. For example, natural gas may slow down your generator and not deliver the desired outcome. Besides, you may have to invest in a larger generator in due course of time. On the other hand, propane is a better choice. However, it is diesel that takes the cake. It is the most preferred solution for generators with 50kW or more. On the downside, diesel costs are skyrocketing, and the fuel also has a short storage life.
Generally, there is an increase in temperature by 10 degrees Celsius when the generator operates. If the ambient temperature is around 40 degrees Celsius, the additional heat will damage your generator. You need to provision and scale your generator for more power to prevent this. You can:
People often overlook the need for strong electrical grounding, which could be a serious mistake when the UPS and generators are concerned. Electrical currents normally use the UPS to dissipate to the ground. Without proper grounding, they will bypass the UPS and use your cables and other devices to get to the ground. This sudden surge of electricity can cause equipment damage, shock hazards, and data loss.
To prevent this, you should:
There's a good reason why we offer this suggestion:
In standby and line-interactive UPSs, battery power prevents frequency variations from affecting the protected load. In contrast, a double-conversion, online UPS recreates the sine wave and filters frequency variations during normal operation. Therefore your battery life remains as good as gold.
Moreover, the online UPS corrects voltage and frequency deviations since it constantly rectifies AC to DC and then inverts it back to AC. Therefore, if you are looking for seamless generator integration, double-conversion UPS is the right choice.
Here are some more pointers to keep in mind to optimise your UPS-generator integration:

The sun is our biggest source of energy. It is clean, uncompromised, unadulterated, sustainable, and renewable. With at least 300 cloudless, sunny days in a year, India is a prime location for capitalising on solar energy. Moreover, the location and demographic of India makes it conducive for deploying solar energy systems. Therefore, signing a contract with your solar panel manufacturer could be a brilliant way to save money and electricity.
Solar panel installation could mean a world of difference for your business overheads. But do they work for everyone? Apparently so. Statistics say India added 8,811 Mega Watts of solar power capacity within January to September 2021. This number is about 280% higher than the previous year's numbers.
According to the Ministry of New and Renewable Energy (MNRE), solar energy contributes 46% share in the total Renewable Energy segment. This makes solar energy the major contributor of renewable energy, followed by wind energy and bio-power.
If these statistics are not enough to convince you about investing in solar panels, we have the reasons to help you understand why it is a worthwhile investment.
Solar panel installation is a long-term investment, and it may take a while before you start generating a decent ROI. Therefore, you should consider a few factors before giving the green signal. You need to:
Coming back to our topic of discussion, here are some of the top reasons to capitalise on solar power installation:
1. Tax benefits galore
The biggest advantage of investing in solar energy is the tax benefits offered by the state and central governments. The government offers tax incentives and financial programs to show their support and consider the high upfront costs of solar panel installation. The top five support systems offered by the Indian government to promote solar energy are:
2. Reduced operational expenses
Solar energy opens the gateway to operating a business almost free of electricity charges. Therefore, no matter how large and profitable your organisation is, a solution with the potential to eliminate such a large expense should be ignored.
A well-designed solar panel system can curb your power bill upto 75%. For example, let's assume you pay Rs.10,000 a month for electricity consumption. Once you've installed solar panels, this number could drop to Rs.2500 per month. You can use the saved money to expand your business or automate your workflow. You could even invest it in a monitoring software that tracks your solar system's energy generation.
The possibilities are endless! So, why miss it?
3. Increased property value
Will your solar panels increase your property taxes? Not likely. Will it increase your property value? Not many people will say no to clean, renewable energy that comes loaded with tax benefits.
Houses and commercial buildings with rooftop solar panel installations have a higher market value than those without them. Moreover, total ownership of the installation allows you to transfer it to the new owner without any hassles.
4. Longevity and sustainability
Solar power is the largest untapped renewable power source with indefinite longevity and sustainability. Every other power source has its limitations.
Hydroelectric power, for example, is clean power but is highly dependent on monsoonal rains. Besides, the need for additional hydroelectric power adds to the risk of flooding premium lands and the destruction of ecosystems. On the other hand, nuclear power is also highly susceptible to accidents and nuclear waste problems. Fossil fuels like coal and petroleum are already facing a bleak future.
Solar power is the clear winner here, harvested as long as the sun blazes on.
5. Low maintenance costs
Commercial solar panels require little maintenance and are virtually silent. The solar cells are encased in a non-corrosive aluminium frame surrounded by tempered, protective glass. As a result, they are built specifically to stand up to the elements, enduring rain, hail, wind, and snow - just about any weather-related threat. Moreover, they are usually located on the roof of commercial buildings, so they are easily accessible for maintenance activities.
6. Low carbon footprint
If you want to be an environmentally responsible business, switching to solar energy would be the best option. Even a small rooftop solar panel can significantly reduce carbon dioxide emissions. Studies suggest that an average 3kW solar system has the potential to power an entire household. Therefore, the carbon emissions produced from one household equals the amount that can be avoided by installing just one solar panel.

7. Elimination of power outages
Unexpected power outages are like a plague for the Indian industrial sector. A single power outage can cause serious problems such as:
However, the situation is entirely different with solar energy. The chances of facing power outages are almost nil as there is consistent energy input to keep your operations running to full capacity.
8. Generates great ROI
When switching to solar power, you are making an investment rather than an expense. This is an investment that generates better ROI than many of your other investments. Many businesses are wary about taking the plunge with solar power installation because of the initial expenses. However, it doesn't take long to harvest your initial investment once your ROI starts rolling in.
9. Complete energy independence
When you welcome solar energy, you assert your independence from being dependant on commercial energy sources. Being completely energy independent also means that you:
10. Support for the local economy
When you opt for solar panel installation, you are simultaneously providing job opportunities for job installation experts in your locality. You are, thereby, boosting the local economy by increasing the job availability for experienced and deserving candidates. Don't forget that these very workers could end up being your future customers!
