1 kVA inverter with 220Ah battery is the most popular inverter set which is designed for a home where power cuts are frequent and for long hours, 4- 6 hours. 1 kVA inverter is good enough for a 2- 3 bhk home for running 5-8 led bulbs, 3-4 fans, 1 television, 1 mixer, and a small 160-liter refrigerator during power cuts. It is a solar-ready inverter on which solar panels up to 600 watts can be connected in the future to run all home appliances from solar during the day.
