It is a part of the solar power generation system. The solar inverter is the key to transmitting the electric energy generated by the solar energy to the power grid. Generally, the process of converting the alternating current electric energy into the direct current electric energy is called rectification, and the circuit that completes the rectification function is called a rectification circuit. The device that implements the rectification process is called a rectifying device or a rectifier.

Correspondingly, the process of converting DC power into AC power is called inverter, and the circuit that completes the inverter function is called an inverter circuit, and the device that implements the inverter process is called an inverter device or an inverter.

The solar cell emits direct current that cannot be used directly. The function of the inverter is to convert the direct current into alternating current.
