The grounding of photovoltaic system is one of the most easily neglected problems of photovoltaic construction personnel, especially small capacity photovoltaic system, people do not attach great importance to the grounding and lightning protection.
But without grounding, it will be wrong because the equipment insulation resistance is too low or the leakage current is large, which will affect the power generation, and even endanger personal safety. Secondly, the metal body without shelter or high position is more vulnerable to lightning stroke, and the grounding equipment may be struck by lightning, resulting in loss of personal property.
Normally, We sunforson take this problem into consideration during design the solar mounting system. As below picture, earth washer and earth lug group solve this problem perfectly.
1. SFS-GC-02(Earthing Washer)
SFS-GC-02----Grounding Clip Application on the Mid Clamp Group----The installation of rail and mid clamp groups
1. SFS-ELG-01(Earth Lug Group)
Earth Lug Groups----The earth lug group fixed on the one end of each pv array
