Best Inverter In India in 2019 | Reviews & Buyer Guide

Are you planning to buy a new inverter or upgrade your old one? Whatever may be the reason, it is very important to understand which are the Best Inverter In India and Out of them which one is Best for your home or office. The power requirement at your home can be different from you neighbor’s home. So do not just blindly install the same inverter (in terms of power) in your home. Before buying an inverter for your home do a little homework and understand the basics.

An inverter can be used for various purpose and at a different place, you must first understand your power requirement.

How Much Power You Need For Your Home Or Office

You first need to understand the power requirements of your home or office dictate the size of the inverter you want to use. This is the total load you want to run on your inverter as a backup. This is the most essential factor to take into account because an inverter is a pure power backup solution for your space. So any misstep in terms of calculating power can lead to a power failure.

What kind of electrical appliances are you planning on running at the time of power failure? This is the addition of all electrical appliances you want to support. According to studies, here is the general power requirement of the most basic appliances.

  • Fan – 75 watts
  • Coffee maker – 1400 watts
  • Desktop computer – 450 watts
  • Dishwasher – 1500 watts
  • Electric heater fan – 3000 watts
  • Fridge – 400 watts
  • Internet router – 15 watts
  • Microwave – 1700 watts
  • Television – 100 watts
  • LED light bulb – 10 watts
  • Standard light bulb – 100 watts

Say you have 5 ceiling fans, a couple of standard light bulbs, one computer, a television, and a fridge. These are all the electrical appliances you want to support during a power failure. This amounts to a total of around 1,600 watts of power requirement.

Find the VA rating of the inverter you need

It stands for the Volt ampere rating. It is the voltage and current supplied by the inverter to the equipments. If an inverter operates with 100% efficiency, then the power requirement of the electrical items and power supplied by inverter is same. But we all know that 100% or ideal conditions don’t exist in real.  Most  inverters have the efficiency range from 60 % to 80%. This efficiency is also called power factor of an inverter and is simply  the ratio of power required by the appliances to power supplied by an inverter. Power factor of most inverters ranges from 0.6 to 0.8.

Hence Power supplied (or VA rating of inverter) = Power requirement ( power consumed by equipments in watts) / Power factor( efficiency).

Here average value of power factor or efficiency  is considered i.e. 0.7

Power of inverter (VA) = 535/0.7 = 765 VA

In the market 800 VA inverters are available. So an inverter with 800 VA will be the right choice for your home.

Be aware of the inverter battery size that you require

It is highly recommended for you to know the size of the battery that you require. A size, which is not compatible with your invertor, will never be able to deliver the desired results.

Consider the bigger appliances

Appliances like air conditioners and refrigerators have motors in their compressors that need a huge amount of current to start. If you want these bigger appliances to run in case of a power cut, you need to increase the VA and size requirement of the inverter and hence the battery.

 

Types Of Inverter

These days, they are being used extensively in applications where there is a frequent power cut off, because in case of power failures, inverters are a very good and efficient power remedies. For every classification, we form some basis first, depending upon which we can further categorize our results for easier understanding and a better approach. This is done in order to promote better understanding and a more extensive classification of different things.

In the same way, we primarily classify inverters on the basis of their output characteristics. So there are three different types of outputs we get from inverters, and hence we classify inverters into three primary classes, which are:

  1. The Square Wave inverter
  2. The Modified Sine wave inverter or quasi sine wave inverter
  3. A Pure sine wave inverter

The Square Wave inverter

A square wave inverter is one of the simplest inverter types, which convert a straight DC signal to a phase shifting AC signal. But the output is not pure AC, i.e. in the form of a pure sine wave, but it is a square wave.

At the same time they are cheaper as well. The simplest construction of a square wave inverter can be achieved by using an on-off switch, before a typical voltage amplifying circuitry like that of a transformer. This is shown below:

The output of this type of a circuit is a square wave.

The modified Sine wave inverter or quasi sine wave inverter

The construction of this type of inverter is a bit more complex than a simple square wave inverter, but still it is a lot simpler than a pure sine wave inverter.

A Modified sine wave shows some pauses before the phase shifting of the wave, i.e. unlike a square it does not shift its phase abruptly from positive to negative, or unlike a sine wave, does not make a smooth transition from positive to negative, but takes brief pauses and then shifts its phase.

The output waveform of a modified sine wave inverter is shown below:

A Pure Sine Wave Inverter

A Pure Sine Wave Inverter

The electrical circuit of a pure sine wave inverter is far more complex than a square wave or modified sine wave inverter. Another way to obtain a sine output is to obtain a square wave output from a square wave inverter and then modify this output to achieve a pure sine wave. A pure sine wave inverter has several advantages over its previous two forms:

  • More efficiency, hence consumes less power.
  • They can be adjusted according to your personal power requirements, since several types are available with different power outputs.
  • The output of a pure sine wave inverter is very reliable, but at the same time, there is a tradeoff between the price and reliability.
  • Due to this reason they are the best option for sensitive equipment.

In the next part, we have listed the top available inverters in the Indian market. All these inverters come from good brands and enjoy reasonable popularity, this list will help you in making the right choice.

Why use distilled water for inverter battery?

Water from faucets, wells and other natural resources usually has dissolved minerals, salts and impurities. These minerals and salts fill the pores and form a layer on the plates, affecting the normal electro-chemical reaction that generates power in the battery. Presence of such chemical ions may drastically reduce the lifespan of the battery. Filtering tap water merely removes the suspended matter but not the dissolved minerals and non-ionic compounds. Advanced filters like ion-exchange or activated carbon filters remove most of the ionic and larger non-ionic compounds leaving smaller molecules in solution.

Distilled water contains no dissolved minerals, salts, organic and in-organic compounds that may harm the battery. Therefore battery manufacturers recommend distilled water for better performance and longer battery life.

Do You Need Inverter Protection?

Overload protection is also known as lightning protection from overvoltage strikes during bad weather. Opting for extra lightning protection for your inverter is important if you live in areas where storms and bad weather is expected. Inverter protection is important because it also reduces overheating, overvoltage, and overload shutdown during emergency situations. (8)

What this kind of protection does is it creates a durable layer between the metal installations and wiring of the inverter. This prevents water from entering inside the inverter’s components and avoids any risk of a lightning strike.

Some of you may have read about “surge protection devices” which are designed to keep such generators safe and efficient, even during a storm. The whole point of buying surge protection for your inverter is for maximum security and power backup during a power cut. Such devices offer just that, and much more. (9)

Broad protection (SPD Type I)

This type of protection offers the highest value and feedback for current resistance. They can handle direct lightning strikes. The costs of using such type of surge protection is low, however you can easily find models of higher value based on the type of inverter you buy.

Some manufacturers offer SPD protection along with an inverter, at a relatively higher price.

Medium protection (SPD Type II)

This type of protection offers a moderate level of current resistance from lightning strike. But the difference is that it is only to protect against indirect lightning strike, unlike broad protection. Inverters protected with SPD Type II are often safe from high overvoltage strikes. They’re comparatively cheaper in price, but are as long-lasting and efficient to use.

Fine protection (SPD Type III)

This type of protection offers the least possible current resistance against lightning strikes. These protect inverters against lightning strikes that occurs a distance away from your home. While they protect highly-sensitive electrical devices, they protect against residual overvoltage even during bad weather.

Looking After Your Inverter

It’s important that you understand the various safety features of an inverter before using it to backup other appliances. While most inverters come with surge protection and overvoltage protection, knowing how safe and efficient inverters are, based on these features, can reduce risk of shutdown or any damage. 

Low battery voltage alarm

To ensure your inverter doesn’t unexpectedly run out of battery, it’s good to opt for a low battery voltage alarm. Such an alarm system will help you keep track of your battery capacity before it discharges completely. Certain alarm systems come with programmable reminders that let you know how long before the battery dies completely.

Low battery voltage shutdown

As opposed to a low battery voltage alarm, a shutdown is when an inverter automatically stops working when it reaches a certain voltage. For example, if the inverter discharges down to 15V, it automatically shuts down. And you can only use the battery again when you connect it to another battery with a higher than 15V current.

Overheating protection

Just like any other powerful battery, inverters produce heat when in use. For this reason, protecting the inverter from heat build-up is very important. The first thing to do to protect against overheating is to place the inverter in a spacious area. Keeping the inverter cramped will increase heat production which can lead to many kinds of damages.

The second thing to look for is overheating protection that is built in an inverter, as a reliable feature. Many brands offer overheating protection features that turn the inverter off as soon as there’s an increase in heat capacity or temperature.

Overvoltage protection

As mentioned in the previous factor, overvoltage protection is important for all kinds of inverters. This is during unexpected weather conditions, especially during storms or lightning. Another kind of overvoltage protection is when the inverter shuts down automatically when the battery life exceeds a certain voltage in order to protect the electrical appliances that are supported by it.

AC output overload protection

A short circuit is a common phenomenon which can potentially harm your inverter and other appliances. The AC output overload feature shuts down an inverter as soon as it produces too much AC electricity. It first stops backing the electrical appliances and later it shuts down the inverter to prevent a short circuit.

Moving forward, here are some ways to increase battery life of an inverter.

  • Some inverters come with distilled water support which needs to be replenished once every 3 months. You can set a reminder on your phone or on your kitchen calendar to check the inverter once every 3 months.
  • The surge connections on an inverter keep the battery and other wiring from rust or debris build-up. The best way to maintain the connectors on the inverter is to coat them with grease. In case there is corrosion on the socket of the connectors, combine warm water with baking soda and brush out the difficult rust spots.
  • For short-lived inverters, re-charging the battery once a month to maintain its inner electrolyte condition is also important.
  • Overloading your inverter with high-powered appliances is a complete no-no; even if you have a maximum surge inverter. Staying energy efficient during a power failure can positively impact the battery life of an inverter.
