A home inverter is a device that converts direct current (DC) from a battery or a solar panel into alternating current (AC) that can be used to run your electrical appliances. A home inverter is required for solar power backup if you want to store the excess solar energy in batteries and use it when there is no sunlight or grid power available.
There are different types of solar inverters, such as grid-tie inverters, off-grid inverters, and hybrid inverters. A grid-tie inverter feeds the solar power directly to the grid and does not require a battery backup. An off-grid inverter works independently of the grid and requires a battery backup to store the solar power. A hybrid inverter can work both with the grid and with a battery backup and can intelligently switch between them depending on the availability of solar power and grid power.
