The inverter, also known as Power regulator and power conditioner, is an essential part of PV system. The main function of PV inverter is to convert the direct current of the solar panel into the AC power used by the home appliance, and the power of the solar panel is all to be processed by the inverter.  Through the full bridge circuit, the general use of SPWM processor modulation, filtering, step-up, etc., the lighting load frequency, rated voltage and other matching sinusoidal AC power for the system end users. With the inverter, the DC battery can be used to provide AC power for electrical appliances.
