PV systems are set up outdoors and are prone to lightning damage. Lightning and surge protections are essential to their efficient operation. After the external lightning protection, the most crucial work is to protect the inverter. SPDs are needed at the DC input end and AC output end of the Inverter. They are also needed at the two ends of long distance signal cable.
