The inverter is indeed a magic device and converts the direct current into the alternating current. It also provides you access to an enhanced performance so that you can continue using your electrical and electronic components even when there is a power outage. In fact, it assumes even more important when you consider a country like India, where the power outage has been a common issue. The term UPS is used throughout the article not just in terms of a computer but other domestic home appliances too.
However, choosing an inverter for keeping the fans, tube lights, water heaters on during power outage may not be an easy task given the fact that there are several options available in the market, and the huge list of technologies can make the task even more difficult. We thought of assisting you in this venture in finding the best inverters for the home in India. Along with that info, we will also attempt learning a bit about the inverter as a device as well.

How to Buy an Inverter – A Complete Buying Guide
Before you actually buy an inverter, it would be essential to check out a few important factors so that the inverter you buy would be able to provide you with a complete power backup solution. A sort of checklist, the list of the best features would help you arrive at the best features.
The above are the few factors which assure you the best buy of the inverters in India. Not just that, we have further shortlisted a few products to ease your task.
List of Best Inverters for Home in India
Having checked out the best features that you should look for in your inverter, here are a few best inverters in India that you can check out. We have made it a point to list out the inverters with the best possible features and the ones that meet most of your requirements. We have also taken into account the different needs you may have.
Luminous Zelio – Best Inverter and Battery Combination for Home
Luminous Hkva – Best Whole House Power Inverter
V-Guard Prime – Best UPS with Battery Backup of 24 Hours
Sukam Falcon+ – Best Inverter for Home in India
Microtek – Best Inverter Under Rs.10000
Now that you have a list of 5 best inverters in India, you simply have to select one among them. However, you shall further read certain information which shall be of utmost importance to you before buying the inverter or a UPS.
Inverter Size Calculator
How can you calculate the actual size of the inverter you would want to opt for? This would need you to go through a series of calculations before you can arrive at the actual size and load requirements.
Go through the following steps and get the best possible calculations.
Calculate the total load
Make a list of the equipment that you want your inverter to provide backup for. Note down the wattage of each of these wattage readings and add them up. As an example, let us calculate a theoretical wattage compilation –
One Fan – approximately 90 watts
One tube light – Approximately 40 Watts
One LED TV – approximately 100 watts maximum
An induction cook top – approximately 1500 watts
The total load here would be 1730 Watts. This constitutes the total load on your inverter.
Calculate the Hours of backup required
Once you have access to the wattage, calculating the wattage hour should not be an issue. Let us say in our example; we need a backup of 6 hours, the total load would be 1730 x 6 = 10380 Watt-Hours. Or 10 kW-Hr.
Do note that the calculations above assume that each of these devices is switched on all the time. This should give you enough room to arrive at the best size of the inverter. You can, however, arrive a the more realistic scenario by multiplying the total watt-hours by 0.8 or 0.6 – if the calculations are for a single room or three rooms.
Find the VA rating of the Inverter
The inverter VA rating should ideally be equivalent to the Watt-hours. However, since the inverters or any similar devices have a power factor, and generally, the Power factor is assumed to be between 0.7 to 0.8 in many cases.
Calculate the VA rating by dividing the watt-hour by power factor. Assuming the power factor as 0.8, in our case, the VA would be 1730/0.8 = 2162 VA. Now that it would not be easy to get an inverter with the exact 2162 VA, you can check out the next right option in terms of VA rating.
Calculate the battery size
If you are looking to go find the right battery size for your new inverter, just in case you need to improve your conditions, calculating it isn’t a difficult task as such. You have a simple calculator to arrive at the right results.
Now that we have calculated the VA rating multiply it by the 6 hours of backup that we are looking for. You will get access to the Vah value for your inverter.
In our example, the Vah rating is 2162 x 6 = 12972 VA. Assuming that the normal voltage of the battery at 12V, the Ah rating of the battery for your inverter should ideally be 1081 Ah. You can now arrive at the right option through that calculation. Choose your battery and the number of batteries you would want to opt for.
If you are wary of calculating all those details yourself, it may be a good idea to go with an online calculator that does the work for you and offers you the right option.
One of the best options in this direction would be opting for the online inverter size calculator offered by Luminous.
You just need to enter the details of the equipments you want to power up and enter their wattage. Do note that the calculator makes use of the theoretical wattage and you may not be able to enter the exact values.
Another efficient option would be to use a calculator designed by V-Guard.
With these calculators, you can easily find out the size and power of the inverter you need for your home requirements.
Different Types of Inverters
The major types of inverters can be classified into two types. Of course, there are a few other types as well, though not much frequently used.
Sinewave Inverters
These inverters will offer you a pure alternating current to your devices. It can be an excellent option if you are using any sensitive devices. They can be the right choice for desktop computers, laptops, camera battery chargers, cell phone chargers, mixer grinders, and small household water pump motors. You will have access to an excellent option for battery backup.
Given the fact that the sinewave inverter supplies the power in the same manner as your equipments receive from a utility supply, you can be assured of really perfect functionality. It will ensure that you can get access to the perfect power supply.
Square Wave Inverters
The wavelength of the current supplied by the square wave is square if you plot it on a graph paper. This has been considered to be the least efficient of the inverter types. Your devices may emit a buzzing sound when used with the square wave inverters.
The devices that we use are designed for use with the sinewave. Using them with the square wave can be quite risky enough. Your devices are likely to get damaged if used with the square wave inverters. Of course, they may not pose any issues with the lights, tube lights, and fans, but if you have heavy-duty equipment, it may not be the right choice for your needs.
There is also an option in the form of a Modified Sine Wave inverter. The inverter output will neither be pure sinewave, nor a square wave.
The Passing Remarks on Best Inverters in India
That was all about the best inverters you can opt for. In addition to the best inverters you can find in India for varied requirements, we have also covered a little information about the multiple inverters as well.
