Solar inverter converts direct current (DC) energy (from batteries or accumulators) into alternating current (AC) (typically 220V 50Hz sine or square wave). Simply put, an inverter is a device that converts direct current (DC) to alternating current (AC). It consists of an inverter bridge, control logic, and filter circuitry.

In short, an inverter is an electronic device that converts low-voltage (12, 24, or 48 volts) DC power into 220V AC power. It gets its name from the fact that 220V AC power is usually rectified back into DC for use, while the inverter performs the opposite function. In a mobile era, with mobile work, mobile communication, and mobile leisure and entertainment, not only is low-voltage DC power supplied by batteries or accumulators needed, but also the indispensable 220V AC power required in daily life. Inverters can meet these needs.
