Inverters

Purpose and Function. Inverters are used to turn the direct current (DC) output of the solar modules into alternating current (AC). This current then flows in the breaker box to be either used in the house or transferred to the electrical grid.. Most appliances and loads within a home use AC current operating at 60 Hz in North America and 50 Hz in most of the rest of the world.
