Best Inverters in India for Home (2020) – Buyer’s Guide & Reviews

If you want to buy the best inverters in India for Home, then you have to look at a few special things. These are discussed below.

What is an Inverter?

An inverter is an electrical device that converts direct current (DC) to direct current AC.

Normally all the electrical things in our house run on AC but when the main power is off this inverter helps to convert DC to AC with its battery backup so that the home appliances can work without any interruption.

Inverters come with a battery where electricity is stored. These inverters are charged with solar energy or electricity so that they can run the electrical appliances in the house when the current goes out.

You can take small inverters if you want to run things that consume a few lights or low current consumption in the house but if you want to run things like big appliances like fridge, AC then you have to buy big inverters.You have to look at which will be the best inverters in India for you as per your need and usage.

There are many types of inverters on the market based on the size of the switching wave from. They all have different circuit configurations, advantages, disadvantages and uses.

How does an inverter work?

An inverter typically produces 220V AC or 110V AC power to the device connected to its output socket when the main current is turned off.As long as the AC does not supply power from the main power supply, the inverter continuously supplies power to the AC voltage output.

Types Of Inverters:-

Inverters are of 3 types in terms of their power supply capacity and usage, such as –

• pure sine wave inverters
• modified sine wave inverters
• square wave inverters

Pure Sine Wave Inverters

pure sine wave inverters is an output wave form of voltage, it gives a very similar output to our utility supply. The biggest advantage of this inverter is that all the appliances we use are designed in Cine Wave pattern.

So it is understood that these appliances will work perfectly in this inverter.This inverter is ideal for those who want to use this type of appliance like AC, microwave oven, washing machine. They work very well and consume very little energy.

Although these inverters are expensive, they can run heavy appliances and consume less energy. These inverters are generally among the best inverters in India.

Modified Sine Wave Inverters

A modified cine wave inverter has one more waveform like a square wave.This inverter works fine with most appliances, but in some cases it gets efficiency and power.

Modified Sine Wave Inverters work a lot like square wave inverters but slightly more complex than square wave inverters but much easier than pure sine wave inverters.

A kind of humming sound can be heard in these inverters. These inverters are much less expensive than sine wave inverters.

The modified inverters are not like the Cine Wave inverters but they look very similar in size. Some of these inverter models are among the best inverters in India.

Square Wave Inverters

A Square Wave Inverters is a type of inverter that helps convert solar DC power to AC power.

This inverter has 4 switches, the switches are a kind of power conductor. These switches are capable of carrying large sized currents and can withstand high voltage ratings.

These switches turn on and off at the exact time at a specified frequency. This square inverter is the simplest and least expensive inverter. But this inverter produces the lowest quality power.These inverters are not among the best inverters in India.

How to Choose an Inverter for Home?

When it comes to buying an inverter, we all have a question in our mind, how to choose an inverter for Home? and Which inverters are the best inverters in India.

Now the problem of load shedding is everywhere. So we should all buy inverters so that we do not face any problem when the current goes out.

When buying an inverter we should note the last few features of the technology. Power requirements, capacity, and battery size are the 3 features we should note.

We have discussed below these features that will help you choose the best inverters in India.

1.Power requirements

The first thing we need to consider when choosing an inverter is getting the amount of Power requirements. Depending on how many appliances you usually want to run.

The “thumb rule” is the guide used to estimate the amount of DC amps required to convert from DC to AC.

Suppose you want to run 3 fans, 3 tube lights, 1 CFL and 1 television after your current goes out. Then you should decide how much power required.

1 Fan                  –          70 Watts

1 tube light        –          60 watts

1 CFL                  –          25 watts

1 Television       –          120 watts

so, your total power requirements is ( 3*70 +3*60 + 25 + 120) = 535 watts

2. Inverter Capacity

In order to select the best inverters in India, we must also look at its capacity. Inverter capacity is usually measured with a volt amp.

If an inverter operates at 100% efficiency then the power requirements of the electrical appliance and the inverter are the same. But we all know that 100% or ideal conditions are not really right.In most cases the efficiency of inverters is 60% – 70%.This efficiency is what is called the power factor of the inverter and is simply the ratio of power required by the appliances to power supplied by an inverter.

The formula for calculating VA is: –

VA = Power Requirement / Power Factor or Efficiency

Power factors are measured based on how efficiently the energy sent to electrical equipment is used.

In India, the power efficiency of an inverter varies from 0.6 – 0.8.

3. Battery Size 

If you choose a mismatched size battery for your inverter, it may not give you good results. So for best results you should take a battery that works well with your inverter.

Battery capacity or battery size is usually measured using Amp-Hour (Ah).This Amp-Hour measures how much current the battery can supply for how long.

The formula for measuring battery size is: –

Inverter’s VA rating X usage time (in hours) / input voltage = Battery size

Let’s understand this with an example :- If you want to use 400 VA inverter for 8 hours backup, then your battery size will be 

400 VA X 8 Hours = 3200 VAh

The capacity of a battery size is represented by AH.This value indicates how much energy a battery can store.A basic inverter battery offers an input of 12 volts. Thus, the Ah value can be calculated as:

3000VAh/12V = 250 Ah

What are the different type of batteries?

You must consider the type of battery when choosing a battery.There are usually 3 types of batteries –

• Flat Plate Battery
• Tubular batteries
• Maintenance-free batteries

1. Flat Plate Battery

These flat plate batteries are first generation batteries. These are also called lead acid batteries.These batteries can be seen in almost all inverters.

The battery consists of two electrodes immersed in an electrolytic solution of sulfuric acid and water.

These can be recharged naturally and generate a lot of current.

These batteries usually cost from Rs 9,000 to Rs 15,000.These inverter batteries are very light.These batteries usually last for 3-4 years but they need proper maintenance.

This battery needs to be replaced with distilled water every 3 or 6 months.Delaying this top up can damage the battery or damage the battery.

In addition, these batteries emit a kind of harmful gas, so these batteries have to be placed in a place where there is very good ventilation.

Nowadays these batteries are getting old so tubular batteries are being used instead.

2. Tubular batteries

Tubular batteries are much more advanced than flat plate batteries.These batteries are very popular and efficient.

These Tubular batteries come with a battery life of 5 years.These last much longer than flat plate batteries.

These batteries are very efficient because they have a deep charging cycle and require relatively little maintenance.These batteries have tubes protected by a cloth in place of positive lead oxide plates.

These batteries are usually expensive. They cost around Rs 9,000 to Rs 25,000.

3. Maintenance-free batteries

Maintenance free batteries do not require any maintenance. These are the batteries that need to be forgotten once inserted.

These batteries are sealed lead acid batteries. These batteries do not require electrolyte level checking and topping.These batteries do not emit any harmful gases so these batteries are very safe.

But these batteries are much more expensive than flat plate batteries and they last much less.

How to Maintain an Inverter Battery

These batteries are usually considered as the main part of storing power. Luminous batteries are better than all other brands of batteries and maintenance of these inverter batteries is also very less required.

Below are some tips on How to Maintain an Inverter Battery –

1. All the time the inverter battery has to be placed in an open place where air is always circulating. And keep an eye on whether the battery is getting hot or not. Never keep the inverter battery in a hot place.

2. Tubular batteries and flat batteries should always be replaced with distilled water regularly. The period for replacing this distilled water is usually between 1 to 3 months and depends on the use of the inverter and the type of battery.

3.These inverter batteries should be kept away from any fuel and in a safe place. In order to prevent fire in the battery.

4. This battery should be checked regularly. If something goes wrong, you have to change it immediately.

5. Thoroughly clean the battery at least once a month and then charge it. This causes the electrolyte solution to regenerate.

Source of the Inverter:

There are two types of inverters depending on the source:-

• Voltage Source Inverter (VSI)
• Current Source Inverter (CSI)

Voltage Source Inverter (VSI)

When the DC voltage is constant it is called voltage source inverter (VSI). The output of the voltage source inverter does not depend on its load.

The wavelength of the load current in this inverter as well as its width depends on the nature of the load resistance.

Current Source Inverter (CSI)

When the input current is maintained constant, it is called current source inverter (CSI). The amplitude of the output current of the current source inverter differs from the load.

The length of the output voltage in this inverter and its waveform depend on the nature of the load impedance.

Difference between an inverter and the UPS

Both the UPS and the inverter work the same. Their job is to provide backups to the electrical system. Yet there are some differences between the two.

The biggest difference between a UPS and an inverter is that the UPS turns into battery power within 3 – 8 milliseconds as the current goes out, while the inverter turns into battery power within 500 milliseconds after the current goes out.

Usually UPS has inbuilt battery so it runs very smoothly and does not take time to turn on and on the other hand inverter does not have inbuilt battery so they run on power with the help of an external battery. So these take a little while to turn on.

UPS does not require battery maintenance but inverter battery maintenance is required.

UPS batteries do not emit any harmful gas but inverter batteries emit one type of harmful gas.

The UPS supplies backup power so that the equipment runs smoothly but the inverter stores power from DC to AC on a converter.

UPSs are usually more expensive but inverters are much less expensive.
