What does a solar inverter do?

Inverters are a critical component of photovoltaic (PV) systems, acting as the intermediary between the solar modules and the electrical grid or the load. Their primary function is to convert the direct current (DC) produced by solar modules into alternating current (AC), which is the form of electricity used by most appliances and the power grid.
