43 specifies the minimum size based on your inverter output circuit current. Bond the grounding conductor to suitable grounding electrodes like ground rods, a concrete-encased electrode, or a ground ring. Use corrosion-resistant clamps. . 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. This concept is an important safety measure that can help you prevent electrical shock and reduce the risk of fire in the. . An inverter can operate without being grounded and will thus be a potential hazard to users as it can cause a nasty, even fatal shock. 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. It will never be connected to AC input and is currently grounded to a copper coated grounding rod (excuse the red wire, it will be replaced with yellow-green).
