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 event of a fault or surge in the system.

What is effective grounding in photovoltaic (PV) systems?

Effective grounding in photovoltaic (PV) systems is the creation of a low-impedance reference to ground at the AC side of the inverter—or group of inverters—that is designed to be compatible with the distribution network’s requirements and existing grounding scheme.

How do you ground a battery inverter?

A grounding wire of 6 AWG must be connected to the grounding terminal on the inverter and connected to a single-point grounding connection wire. If there is no suitable grounding connection point, then the grounding wire from the inverter must be connected to the negative terminal of the battery bank for off-grid systems.
