Suntree Surge Protective Device for PV Solar System DC 1000V 20KA/3P Surge Arrester for PV System II Classified Test UP 3.8KV 10mm Stripping Length

Description

Lightning and surge protection for PV systems installed on buildings Please take the following measures to protect the PV system from damage of lightning impulse or surge voltage : All metal parts (such as framework,support,etc) of PV system must be connected to the main equipotential bus to ensure reliable equipotenftial connection of the whole system. Must keep a safe distance (S) between all parts of PV systems and the extermal lightning protection system.The external lightning protection system can be connected to the main equipotential bus fundamental earth screen or ground ring only.
