Microinverter:A microinverter is a type of inverter that converts direct current (DC) into alternating current (AC). It is typically used in photovoltaic (PV) systems to maximize power output from PV modules. A microinverter consists of a DC-to-AC converter and an AC coupling circuit. The DC input voltage is converted to AC output voltage by the DC-to-AC converter. The AC coupling circuit then couples the AC output voltage to the PV module.
