The main function of the
string solar inverter is to convert the direct current generated by the solar panel into the alternating current used by the home appliances. Through the full-bridge circuit, the SPWM processor is generally used to modulate, filter, boost, etc., to obtain a sinusoidal AC power that matches the lighting load frequency, rated voltage, etc. for the end user of the system. With an inverter, a DC battery can be used to supply AC power to the appliance.
