Earthing/Grounding Equipment
Grounding provides a path for fault current or lightning surges to flow through to protect people and equipments from electric shock hazards. PV modules mounted to metal racks should be effectively grounded using conductor rod, plate or electrical wire buried into the ground to provide a low resistance connection to earth. Most PV systems involve both DC and AC system, and they are considered two different systems. So DC grounding and AC grounding should be maintained separately.
