It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. This article covers grounding in PV systems, which differs slightly from standard grounding 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.
Modern grounded inverters and PV arrays are not isolated from the grounded output circuit of the inverter. In this scenario, the equipment grounding conductor (EGC) of the PV circuit can be connected to the grounding terminal of the inverter, which is eventually connected to the AC grounding system and electrode within the premises.
If there are multiple inverters used in a PV plant, only one grounding bank is required at the PCC to achieve effective grounding for the whole plant.
