Surge Protection for Solar Power / PV System

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 invertor. Surge protection devices (SPDs) are needed at the DC input end and AC output end of the invertor. They are also needed at the two ends of long distance signal cable.

Prosurge has a lot of surge protection projects for solar / PV installation. Please check our surge protection projects around the world here:
