The recommended approach is to use a separate DC grounding electrode for PV arrays and frames, as this enhances protection against lightning and transient voltage. . Grounding is the act of connecting an electrical system to the earth to provide a reference and help limit voltage from lightning or system transients; bonding is the process of connecting normally non-current-carrying metallic parts together to create an effective fault-current path. This article covers grounding. . An SMA product (PV, hybrid, battery or Sunny Island inverter) is part of a PV system in which each component, if connected incorrectly, can affect the system in an undesirable way. For lightning protection associated with grounding systems, refer to NFPA 780 and NEC 250. Solar ABCs, with support from the U.
