How to Select Inverter for Home?

As power cuts are becoming more and more frequent, these days, it has become very important to have an inverter at home. I have suffered a lot because of power cuts, and because of that, I planned to get an inverter for my house. So, how to select inverter for home? I looked up the process online and came to know there are three basic steps that I mentioned below. 

How to Select the Inverter for Home?

The process of selecting an inverter for your home is easy and here are the steps that you need to take. 

Understand the Power Required

To know the power requirement, make a list of the appliances in the house and add them together. For example, if you have two fans of 70 watts each, 1 tube light of 40 watts, 1 TV of 70 Watts and 1 refrigerator of 140 Watt, then the power consumption would be.

= (2x70) + (1x40) + (1x70) + (1x140) = 390 Watts

Calculate the Inverter Capacity

To calculate the amount of power required, you need to divide the total power in watts by the power factor of the house. The power of a house is 0.7. So, we can take the power requirements from the first step and divide it by 0.7. 

Inverter capacity = 390/0.7 =557 VA. 

Calculate Battery Capacity

To calculate that, you need to multiply the inverter capacity with the required backup and divide that by the voltage of the battery. So, if we take a battery voltage of 12 volts and a backup time of 3 hours, then it becomes (557x3) / 12= 139 Ah.

And that’s it. I hope you find this helpful.

Power cuts are a major problem in India, especially during the summer and monsoon seasons. During work from the home era, I found this issue a lot. I would work or join a meeting and suddenly I would realize that there is a power cut in my area. This situation hampered my day and my work. I had to resolve this issue finally, so I decided to purchase an inverter for my home. Let me share with you my experience on how to select inverter for home.

How to choose inverter for home?

• Identify your power requirements:

The main thing we should decide while purchasing an inverter is what appliances need to run when there is a power cut in the home. When I purchased my inverter I wanted to connect 2 lights, 1 fan and 2 CFLs with the inverter. After calculating I found that I need a total of 170 Watts to run all these appliances. So, when I was looking online I checked out an inverter that can provide 170 Watts when there is a power cut in the home.

• Check the VA of the inverter:

To buy an inverter, we need to realise how many Volt Amperes can the inverter supply to the appliances. Calculating the VA is fairly simple. By dividing the power requirement by power factor, we can get the VA easily. Let me illustrate with an example:

The average power factor of VA is 0.7 or 0.8

VA= 170/0.7

VA= 242.85 Approx.

Hence, in this situation, we need an inverter with 250 VA.

• Buy inverter with appropriate battery

To decide how to decide inverter capacity for home, we should focus on buying an inverter with an appropriate battery. That means how many hours an inverter can run your appliances. Let's just say you need 6 hours back-up when there is a power cut. 

• Ratings

Before purchasing an inverter you should also check out the price, ratings, and reviews and then buy an inverter. You should always buy an inverter that you can utilize for a long period of time.

This is the process on how to select inverter for home. I hope you find this informative.
