Inverter Buying Guide

A inverter is a electronic device that converts direct current (DC) to alternating current (AC). The inverter with battery stores electricity and during a power outage the inverter converts the stored DC power from the battery into AC and gives the power to your home.

Inverter Buying Guide 2021 – How to choose the best inverter

Calculate your Power Requirement:

First you need to calculate your power requirement that how much backup you want or how many appliances you want to support. Bigger appliances require high power requirement.

Appliance	Power Consumption in Watts
Television	130
Fan	90
Tube light	40
CFL	20
LED bulb	7
PC Computers	150-250
Mixer	400

Now calculate. For example if you want 2 fans, 1 tv, 3 tube lights, 3 led, 3 cfl and one computer to run, then (2*90+130+3*40+3*20+3*7+250 =761). So you need a inverter which can support 761 watts. These above values are approximate. If you want the correct value then check with your appliances.

Inverter capacity calculator:

The inverter capacity is measured in VA (Volt Ampere).

Total Load / Power Factor = The inverter capacity

For example: 761/0.8 = 951.25 VA
Here Power Factor is 0.8

So you need to better consider more than 951.25 VA inverter to support your power requirement.

Types of inverters

3 types of inverters are available in market. Pure sine wave, Modified Sine Wave and Square Wave Inverter.

Pure Sine Wave Inverter
Most of our electrical appliances are compatible for operation on sine waves. Safety of appliances is high and little noise. Cost of this type of inverter is little high.

Modified Sine Wave Inverter
Between pure sine wave and square wave. It can reduce the efficiency of the device but modified sine wave inverters are affordable.

Square Wave Inverter
Not all electrical appliances work with these and cheapest. Safety of appliances is less and noise level is high.

It is better to select a sine wave inverter for your home.
