Power cuts could prove detrimental to your machinery if they are not properly maintained. Depending upon the reason for the power cut, it has a different effect on the home. If an overload is causing abrupt spikes in electricity, the central power grid may get severely damaged and cause overheating of the appliances. If the power cut is due to undue power failure from the mains, it is usually less detrimental. Still, if it often occurs, in the long run, it may reduce the efficiency of your machinery as it pushes itself to function against the low voltage. Some machines require more energy to start rather than run for long durations. A higher electricity bill is consumed in regular power cuts, and a higher electricity bill is generated.

Power cuts could also be due to faulty wiring and structural weakness in the electricity grid at home. That endangers the lives of the inhabitants of the house and may even damage society's central grid. Faulty wiring is one of the lead causes of electricity-related fires globally and is highly prevalent in Chennai's developing areas like suburbs or rural areas surrounding Chennai. Not to mention; the gross inconvenience caused to the households. Computers may stop working, which may lead to loss of data or inadequate job productivity.

Refrigerators and microwaves might stop functioning, and if this goes on for long, a lot of food might get wasted. If the aqua-guards do not function, potable water might not be available. This problem is severe for Chennaites because of the severe water shortage already existing in the city. So, several issues can arise from power cuts. In June 2019, there was a power cut almost daily, affecting the health of lakhs of Chennaites amid summer!

So, let us take a look at some of the solutions:

• Monitor your equipment:

Buy and use quality products and maintain them. Faulty wiring or low quality of semiconductors in the machinery itself may cause damage to both the machinery and the home's wiring. Make sure that all wires should be insulated, and the machine should not cause a shock.

• Monitor the power quality:

If you notice that the current is facing fluctuations, it could be due to harmonic wave interference caused by low lights or switched-mode devices. It is advised by Nantech to install an active Harmonic filter or a servo stabilizer to prevent any power quality-related complications.

• Get to the root of the power problem:

Ask your neighbours if they face a similar situation to determine if it is a problem in your house or a defect in the central electricity supply. If there seems to be a central problem, promptly inform the authorities. If it's a problem at home, check using a tester if there is any problem with the machine you are having trouble with. If you suspect some other cause, call a technician immediately.

• Use good quality circuit breakers:

This will ensure that you will not be a victim of power surges, and most of all, you will be protected from electrocution or fires that may prove to be fatal.

What is a Servo stabilizer?

It is an automated electronic system built to attain constant voltage levels. They protect the appliances by forming a closed loop of an absolutely controlled system. Even if there is a fluctuation in the input voltage or load, the resulting output voltage will remain invariable. It is also commonly called Servo Controlled Voltage Stabilizer. It works on the principle of servomechanism or feedback. They are used for maintaining the accuracy of high voltages with an output correction of about +_ 1%. They are installed at various institutions like hospitals and clinics, food processing units, hotels, Flour mills, etc.

Chennai is currently the largest electronics hardware exporter in India. It contributes a major chunk of Indian exports. One such company based in Chennai is Nantech Power SystemsPvt Ltd. It is one of the most promising manufacturers and suppliers in the field of building powering equipment. A few specifications of its servo stabilizers are as follows:

• It is a three-phase stabilizer that protects the appliance against the under-voltage condition or sag, over-voltage condition or surge, and other such imbalanced voltages.
• Its design type includes an O/P sensing feedback system with a feedback mechanism where the feedback voltage controls the servo motor rotation. Its rotation adjusts the brushes' position on the autotransformer, creating a voltage difference. This voltage difference is then fed to the buck-boost transformer, a series transformer that stabilizes the output voltage and gives a stabilized and regulated output.
• It has an Opto Coupler based Triac motor drive.
• The type of motor is an A.C synchronous stepper motor, which when in the state of equilibrium, manages to bring the rotation of the shaft and the frequency of the supply current in a synchronous manner such that the rotation period and the integral number of AC cycles are equivalent to each other.
• The output voltage can be adjusted to 415 V or 380 V, or 400 V.
• True RMS is used for sensing and correction of voltage as it has more accuracy.
• The overvoltage cut off has an upper limit of +5%, meaning that if there is an increase in voltage by 5%, there'll be a total cut off. The under-voltage cut off has a lower limit of -10%, which suggests that if there is a decrease in voltage by 10%, it will result in total cut off until the voltage comes back within the range. This will help in maintaining the safety of the appliance.
• HRC fuse or MCB or MCCB are fitted at the input to prevent the appliance from getting damaged if there is a short circuit.
• In case of overload, it will sustain a current greater than 10% of the maximum rated output current.
• If one wishes to reset, the restart option is manual and automatic, depending on what the user wants. This makes it user friendly.
• The servo stabilizer's efficiency is more than or equal to 98% with an inbuilt phase reversal protection.
• With an ambient temperature of 0° to 50° C, it works with great efficiency.

Servo controlled voltage stabilizers are preferred over the other relay and static type of voltage stabilizers because they come with the exact system, react quickly to any variation in voltage, manufactured in a user-friendly manner with an overall well-equipped circuit ability to sustain a high voltage surge. There is absolutely no compromise on the security of the user. Furthermore, it acts like an amour for the appliance as well.

Solar Energy is now taking the world by storm. We can see this in the many advancements in technology by our Indian scientists and by the Indian Government's proactive legislatures. In 2018, the Chennai Civic Body had launched a Rs. 140 Crore venture project which plans on changing 70000 streetlights in over 15 zones, out of which 8 zones – Thiruvottiyur, Manali, Madhavaram, Ambattur, Valasaravakkam, Alandur, Perungudi, and Sholinganallur are all going have 17000 redone post lamps with streetlights introduced. Estimates are that this project could bring a 45% lessening in electricity consumption.

The focus is now on more greener and efficient technologies like solar streetlights, which use solar panels and LEDs. But why must you change over to Solar Street Lights? We shall present you with 5 compelling arguments to switch over to Solar Streetlights in Chennai!.

Solar Power is the conversion of energy from sunlight to electricity. It is one of the essential sources of renewable energy. It uses radiant light and heat from the sun that is harnessed using technology devices such as solar heating and cooling systems, solar thermal, photovoltaics, concentrating solar power, and converts it into electricity. Solar power is one of the cleanest and reliable forms of renewable energy. The devices used to collect the energy are explained in simple terms below.

Photovoltaics

This is a process of converting light into electricity using semiconductors that exhibit the photovoltaic effect. This effect is used commercially for electricity generation and as photosensors.

Concentrating Solar Power

These generate power by using mirrors or lenses to gather the sun's energy onto a receiver and further drive them to traditional steam turbines or engines to create electricity.

Solar Heating And Cooling Systems

Collect thermal energy from the sun to provide hot water, air conditioning, pool heating for resident or commercial usage.

Solar Inverters are a type of electrical converter which converts direct current (DC) output of a photovoltaic panel into a utility frequency alternating current (AC) that can be used for electrical grids, which can be used by local, private networks. Solar Inverters use MPPT (Maximum Power Point Tracking) to get to the maximum possible power from the photovoltaic array. The purpose of MPPT is to sample the cells' output and determine a resistance/load to obtain maximum capacity. Inverters are also referred to as the brains of the entire solar power system. One of the components includes the battery storage system. Stored batteries can be used in the times when the sun goes down during evening and night time.

Solar Inverters are divided into three different types.

• String Inverter
• Micro-Inverter
• Power/ Central Inverter

Stay tuned till the end for some detailed guidance on solar inverters and their types on Nantech.

String Inverter
A string inverter is one of the popular devices used among households. It works well with All Home appliances. It converts Direct Current from solar panels to Alternating current electricity/power. Multiple strings are connected to produce electricity.
String Inverters are also known as Sine Wave Inverters. These can be paired with power optimizers.

Solar Micro Inverter
Solar Inverters used to operate with a single PhotoVoltaic model is known as Solar micro-inverters. These micro converters convert Direct Current(DC) output to alternating currents(AC). It is used for parallel connection of various units (multiple, Independent) because of its design. Micro Inverters are small in size and are plug-in and play a kind of device. These are connected in parallel to each other and then to grids while producing grid-matching Alternate Current(AC) directly at each solar panel bank.

Central Inverter
Just as the name suggests, Central Inverters are connected to form a standard combined inverter that converts the power to an Alternating current (AC). These are usually bigger and than String Converters. Thus, they are only suitable for covering large areas and not for primary household usage. Central Inverter can handle up to 500KW per enclosure.

Solar Inverter gives the benefit of using solar energy without hefty bills of electricity from our power supply. Solar Energy is the most acceptable renewable energy solution for this world full of electronic devices that needs to be charged before use. Thus, using electricity from solar panels and solar inverters might be the best renewable solution one can ever think of.

Let's start with the fact that Solar inverters are among the most efficient machines built by man, giving up to 97% efficiency in the best inverter and under ideal weather conditions. When we say efficiency we mean, the solar inverter's capacity to convert all the energy it receives from the sunlight into the alternating current it supplies to the devices it is connected to. The amount lost is mainly due to converting the direct current received from the solar panel into the alternating current supplied.

The solar inverter can be referred to as the system's brain as it has 'Maximum power point tracking ability,' which is a feature of genius. It is basically a sensory system that can detect when the battery is connected. The inverter itself is full storage capacity and then breaks the circuit stopping any more from the photovoltaic solar panel. This is an essential protective feature of the solar inverter because it helps prevent an acute decrease in efficiency and protects from any physical mishap.

Grid-connected solar inverters are large scale solar systems where All the panels supply DC to the grid where the main inverter structure would convert all the DC into AC and supply residential and office buildings. Though a little pricey to install, this system will give huge returns in the long term due to its high efficiency and eco-friendly nature. These solar power plants can last for more than 40 years, after which some machinery might need to be replaced. This becomes important when you know that 'One hour of total sunlight hitting the earth is equivalent to one year's worth of energy for the planet.' It is the cheapest energy source as there are no costs to obtain the raw material. For example, you need coal mines to dig up coal.

Many people are under the impression that Solar energy is not a viable source because it is weather dependent, i.e., it will be useless on cloudy days or winter. As a matter of fact, 'Solar energy does not need direct sunlight but only the warm temperature generated by sunlight.' You do not particularly feel cold on cloudy days, you can take cloudy days in the summer as well, but the solar inverter will work just as well.

For you enthusiastic and nature-loving homeowners, here are a few facts helping the cause of solar energy:

• According to surveys done in the USA, most homeowners have found positive returns on investment within 10 years of installation.
• Solar panels are fast and easy to set up.
• In 30 years, your home's typical isolated solar system can reduce CO2 levels by 100 tons.
• The average solar panel has a 25- year warranty, and the attached solar inverter has at least 2 years of warranty.
• Solar energy is cheaper than fossil fuels.

So, what are you waiting for? Go ahead and buy a solar inverter to save both your money and the environment!
Happy shopping!

Today, fossil fuels and their by-products are being scrutinized by the world, and the focus is more on greener and environmentally friendly sources of energy. Solar Energy, mainly the use of Solar panels, has gained much traction in this field, It uses Solar Photovoltaic (PV) Cells to capture sunlight and convert that to electricity.

However one must remember that solar panels usually provide Direct Current (DC) energy. Most of our household electrical appliances use Alternating Current (AC) energy. Thus, we need to convert DC to AC, and this is where we use a solar inverter. This device converts the output current from the solar panels to AC energy, which can be used in your house.

There are many advantages to using a solar inverter:

• It reduces Greenhouse impacts since solar energy is being used.
• It is very financially practical and reduces electricity bills to a great extent.
• They are easier to set up and operate as compared to traditional generators and inverters.
• Ease of maintenance and repairing
• A reliable source of conversion from DC to AC
• Helps reduce the energy needs of households and businesses to a great extent
• Many gadgets can make effective use of the inverter's current, for example – solar cookers, solar heaters, etc.
• It also allows for better control for homeowners and businesses in monitoring their energy usage.
• Usually, these systems have a long life (up to 25 years)

Today, there are three types of Solar Inverter technologies that one can choose from:

String Inverters (a centralized inverters)

In a PV system with a string inverter, the panels are wired together with 'strings,' Each panel's output can be sent back to the central inverter via this 'string.' This allows for a low-cost inverter operation and is durable and easy to maintain. These are best suited for houses with simple roofs that get sun throughout the day and for people looking for an economical and low-cost PV system.

Microinverters (individual panel inverters)

These are different from the string inverter system, and here, the solar panels each have a small inverter installed. Therefore, the conversion from DC to AC occurs right on the roof. The advantage of this system is that for systems that experience shading or have more complex designs, one can use this instead of a string system to mitigate the problems. Furthermore, it allows for panel-level monitoring since each microinverter is connected to the solar panels. These are usually high-cost, high-performance inverters, and hence one must use them for complicated roof constructions.

Power Optimizers

These fall in between microinverters and string inverters. These are interfaces located near (or on) the solar panels, which 'condition' the DC output and send it back to a centralized inverter. The advantage is that it helps monitor individual panels, mitigate the impact of shading, optimize the efficiency of inverters, and cost less than microinverters. These are best suited for houses or buildings with less ideal solar panel locations and whose owners are willing to pay a little extra for a better system but don't want microinverters.

Nantech Power Systems Pvt. Ltd provides the best inverters to buy in India, with its excellent product line-up, efficient services, and timely after-sales support. Check it out!

What better time than now to invest in environmentally conscious and economically sound power supply machinery? So, an inverter's basic function is to save electricity when power is available and, on the occasion of a power cut, supply power to run at least the basic machinery and appliances like fans and lights to help the user. Solar inverters like the ones made by Nantech are created using solar power as the inverter's primary power supply.

Solar inverters for residential use are of the following types:

Off-Grid stand-alone inverters: These are isolated inverter systems usually supplying only a single home or office building.

Grid-connected inverters without battery back-up: Here, all the converted solar energy is stored in a central grid system supplying multiple buildings and acts as a back-up for all these buildings when there is a power- cut. There are no batteries, and these inverters have PowerPoint tracker systems for systemic power generation.

Grid type inverters with battery back-up: An amalgamation of the above two types of inverters.

Offred grid inverters are mostly used for residential users and are capable of supplying enough power for essential needs. However, it is of paramount importance that a customer knows what he is buying to avoid any kind of mishap, whether financial or physical. So here is a list of few things you should keep in mind while buying a solar inverter:

Battery Voltage range: The voltage that can be fed into the battery from sunlight.

DC current: Maximum current which it can handle.

Voltage range: The voltage that can be fed into the inverter by sunlight.

Continuous power output: The maximum time the inverter can produce continuous power at said temperature.

Output voltage: So that it is compatible with your household requirement, which is generally 210-220V.

Frequency: For India is 50 Hz.

Efficiency: The amount of actual solar energy received by the panels converted to electrical energy supplied to our homes. No Machine 100% efficient. We recommend solar inverters with galvanic insolation having an efficiency of 94% and 97% for without galvanic isolation.

No-load power consumption: The amount of energy that the inverter itself uses up without supplying to a load. It is important to determine efficiency.

Surge Power: some machines, like motors, require more power to start than the rest of its run time. We recommend surge value between 3- 6.

Output waveform: We recommend a pure sine wave property for high efficiency.

Maximum power point tracking ability: This system prevents overcharging and under-charging of the inverter.

Output voltage: So that it is compatible with your household requirement, which is generally 210-220V.

Ambient weather conditions: To preferably include your room temperature range and average humidity.

Grid frequency synchronization range: 3 Hz

Ingress protection rating: It is a protection rating, and its minimum value should be IP65.

Power factor: Greater than 0.9.

Data logging software: For user information and convenience.

Inverter warranties: Should have at least a 1-year warranty.

Servo Voltage Stabilizers are important electrical components for the electrical wiring of the complex. It protects electrical equipment and machines by stabilizing the voltage input and protecting it from voltage fluctuations (both over and under supplies) and other voltage floods. Hence, this is also known as an Automatic Voltage Regulator(AVR). These work with many electromechanical transfers to give a suitable yield voltage, which is usually in an ideal range.
These come either in single-phase or three-phase units, depending on the use and the connection to limit the Kilovolt-Ampere (KVA) necessary. Three-phase units further come in two different types: Balanced Loadand Unbalanced Load models.
Furthermore, they are either for a piece of particular equipment or a spot or a major stabilizer unit for a group of apparatuses (E.g., an entire house). Also, they come in computerized or as simple stabilizer units.

There Are 3 Main Types Of Servo Voltage Stabilizers

Relay type Voltage Stabilizers

Apart from the transformer circuits, a rectifier circuit, controller unit, and other parts are used for bucking operations. These are relatively easy to use and have less weight, and are commonplace in households and businesses.

Instabilities are ±15% with yield exactness between ±5-10%.

Advantages:

• Economical
• Easy to use

Disadvantages:

• Relatively poor construction
• Less dependable
• Poor reaction to voltage vacillation

Servo Controlled Voltage Stabilizers

They use servo engines to control voltage influx and hence are also called Servo Stabilizers. These have closed-circle frameworks and are basically used for high-precision voltage returns (typically around ±1%). These come in 3 types:

• Single Phase Servo Based Voltage Stabilizers
• Three Phase Balanced Type Servo Based Voltage Stabilizers
• Three Phase Unbalanced Type Servo Based Voltage Stabilizers

Advantages:

• Quickly reacts to changes in voltage.
• High Precision in voltage stabilization
• Firm construction and circuital housing
• Ability to withstand high voltage floods

Disadvantages:

• These stabilizers need intermittent upkeep and maintenance because of the moving parts.
• The servo engine must be pre-validated to avoid problems, and the plan of servo motors needs a skilled worker.

Static Voltage Stabilizers

These stabilizers have static parts and hence no moving parts as compared to a servo voltage stabilizer. These stabilizers are extremely accurate and have an exactness of voltage adjustment range of just ±1%. These static voltage stabilizers contain 'Buck & Boost' Transformers, Microcontrollers, Microprocessors, and other important components.

Advantages:

• Small Size
• Rapid reaction to voltage vacillations
• Remarkably high exactness of voltage adjustments
• Breakneck correction speeds of 20kHz
• Auto Bypass
• Silent operation
• No moving parts; hence, it is nearly upkeep free.
• Very dependable units
• High productivity

Have you ever wondered, when someone by mistake inserts their finger into an electric socket, they get electrocuted, and the finger burns? But when the same finger touches the net of those electric rackets for mosquito killing, you feel nothing more than a small shock wave with no physical effect? So it is quite evident that, based on the current, more accurately, the voltage flowing through a conductor, damage, or magnitude of use of the machine is proportionate. Just like us, even devices have a specific limit of voltage that they can handle without damaging themselves.

Generally, power lines from the power plant operate at super high voltages ranging from 155,00V to 765,000V. If that amount of voltage were to directly reach our homes and factories, all our machinery would burn down. Therefore, along the way, with the help of step- down transformers, voltage is reduced to about 120-220V till it reaches our homes. Unfortunately, this system is not properly developed in all parts of our country. There is usually an undesirable fluctuation of voltage and sound production due to interference and spikes in current, which may damage sensitive machinery in homes and factories. To guarantee the machinery's safety, 'The ultra- isolation transformer’ was created and manufactured on a large scale by various companies, including Nantech. The Ultra isolation transformer works on the basic principle that makes strong insulation amongst its primary and secondary coil, capable of withstanding surges in voltage. This essentially creates a barrier between the source of power and the machine or load, ensuring the machine's safety and any hazards that might arise from the unstable power supply.

Another important use of the isolation transformer is that it reduces electrical noise and enables good electromechanical compatibility. Suppose we pay attention to its internal structure. In that case, we observe that the number of windings in both the primary and secondary coils is the same and is often used to protect other connected circuits and individuals from shock. There is a capacitive coupling between the two coils with a faraday shield to enable the transfer of energy but reduce common-mode noise.

PROS OF ULTRA ISOLATION TRANSFORMERS:

• Enable safety
• Reduce noise interference- both standard mode and differential mode.
• Increase efficiency by blocking DC currents
• Used in various sectors like Power industry, Aviation industry (Austin Transformer), Pulse circuits, and general appliances like computers, medical devices, factory machinery.
• A significant part of electronic testing

Cons of Ultra Isolation Transformers:

• Cost is the only significant issue as it is advisable to have an ultra- isolation transformer, but customers may not buy it or underestimate its use.

Nowadays, due to its wide range of applications, Ultra isolation transformers come built-in with high-risk devices and are indeed a marvel of human innovation. Working on a simple principle helps entire humanity avoid harm from the lifeline of society that is electricity.

The type of electrical converter that can convert the variable direct current output of a photovoltaic solar panel into a utility frequency alternating current fed into a commercial electrical grid is known as Solar Inverters. Unlike the regular invertors, the solar panel charges the battery using solar power along with the electricity. For supreme efficiency of these solar inverters, systematic and consistent maintenance ensuring their efficacy is required for the long run of the machine.

Utilities of Solar Inverters

• • Eco-friendly approach

Solar power installation provides for the benefit of the environment as this process requires no fuel burning and no radiation from energy production. Since it is pollution-free, most of the population will tend to purchase it as protecting the environment is considered the main motto of all individuals who are very well aware of the haphazardness of filthy surroundings.

• Solar Heating for home appliances

The electricity generated from the solar panel can be used for smooth functioning of all electronic appliances in the home. The exorbitant current bill, which is unaffordable to middle-class people, has become more conducive to a solar heating panel. Sudden reduction in electricity bill makes everyone purchase this solar inverter as it reduces the cost of living and provides enough money for savings. It is the main heating mechanism of all homes, especially in foreign countries. Most housewives find cooking in solar energy less tiresome and an enjoyable pastime making the work less monotonous. Solar power cars are already in the market, which invariably reduces the fuel cost.

Advantages of Solar Inverters

• • Solar energies are a renewable source of energy

Since the sun is visible throughout the year, solar energy is a continuous process, and we cannot be in shortage of it at any point of time.

• Solar power reduces electricity bills

The electricity bill of houses reduces to a considerable extent after installing solar panels, which makes it more reliable and to gain more future buyers.

• • Solar energy is pollution-free

Greenhouse gases like carbon dioxide and methane, which cause pollution, are not caused by solar energy, making it eco-friendly.

• It’s capacity to store power

We can store solar energy by increasing the number of batteries, which can be later used on a cloudy or a rainy day.

• It reduces maintenance cost

Once the solar power installation is done, it easily lasts for more than twenty-five years, reducing the maintenance cost.

Disadvantages of Solar Inverters

• • Solar energy is dependent on weather

It is extremely difficult to collect solar energy on a rainy or cloudy day as its efficiency decreases to such a low level during these days even though the energy can be stored through batteries.

• Installing a Solar panel requires a lot of space

To fit many solar panels, ample space is required in the roof area of the house. The place where the solar panel is kept should be accessible to exposure to direct sunlight. Hence solar inverters should be fixed only in places congenial for this.

• Maximum efficiency is unattainable

Since solar inverters can't convert all their available energy into power, 100% efficiency is not arrived at by the constant use of these solar panels.

To put it in a nutshell, solar energy, which is gaining popularity through its technological development, will take some more years to reach the peak of its utility and to improve the quality of our life. By 2050, we can expect every single house to have a solar panel installed on its roof, which makes it an essential set up not an option.
