Ans. Inverter is an electronic device that is used for the conversion of Direct current (DC) into alternating current (AC). It is used to power electronic appliances that are based on AC power supply when grid is not there and just DC power sources are available. 

An inverter uses electronic circuit systems for converting DC power from sources to AC power. This process includes the techniques of switching and modulation that are used for creating an AC Waveform from DC input. For efficient management of the conversion process, these circuits can include transformers, transistors and control systems. 

To know the right inverter capacity for your needs, you need to calculate the total wattage of the appliances that you want to run in case of power cut. On the basis of this total load, you can select the inverter with suitable VA rating. 

An inverter is a specific device that stores energy and is used in the power backup system. The stored energy in batteries (DC power) could be converted into energy to run electronic appliances (AC power) in the case of power failure. 

The best battery for home or office usage is the one that offers high performance coupled with low maintenance, affordable price and longer lifespan. You should go for trusted inverter battery brands like Genus to get high-performing batteries that offer reliable operation even during frequent and long power cuts.
