Proper grounding of a photovoltaic (PV) power system is critical to helping ensure electrical safety during its lifetime. PV equipment needs to be properly bonded, in addition to code-compliant grounding, so that the low current flows on metal parts can facilitate the operation of over current and ground-fault protection. .
UL 3703, the Standard for Solar Trackers, involves rigorous inspection and evaluation of a tracker platform and also references UL 2703 for electrical requirements related to the mounting, bonding and grounding. .
The following standards apply to electrical and electronic equipment in select industrial locations: 1. IEC 61000-6-2: Electromagnetic compatibility (EMC) - Part 6-2: Generic standards - Immunity standard for industrial. [pdf]
