Here are some key grounding-related requirements from the NEC that apply to solar inverters: NEC 690. 41 – Requires that the PV array frame and any exposed metal equipment like inverters must be properly grounded. This prevents shock and fire hazards. This document does not replace any regional, state, provincial, federal or national laws, regulations or standards that apply to the installation, electrical safety. . Nearly all solar inverter manufacturers require proper grounding to maintain their equipment warranties. Without it, any problems resulting from surges or malfunctions would not be covered. Not grounding your solar inverter puts your entire solar. . Grounding a solar inverter is referred to as connecting the metal casing of the inverter to the earth, creating a path for extra electrical current to be safely discharged. An ungrounded inverter will contain live points, which, when touched, will send a current through your body to the earth. Your body has completed the loop to earth.
