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. For lightning protection associated with grounding systems, refer to NFPA 780 and NEC 250. Why do I need a. . Grounding (also known as earthing) is the process of physically connecting the metallic and exposed parts of a device to the earth. It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. Are lightning protection and grounding a non-negotiable safety measure for C&I PV power plants?. Without adequate lightning protection and grounding, a single lightning strike can disrupt power production, damage expensive solar equipment, and lead to costly repairs and downtime. This is especially concerning for large-scale C&I PV plants, where system interruptions can result in significant. . For grid-scale battery energy storage systems (BESS), grounding and bonding is essential for safety and performance.
