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.
Earthing in Solar PV Systems is crucial for their safety and performance. It provides a low-resistance path for fault currents, preventing electrical shocks and equipment damage. Grounding also enhances system longevity by protecting against lightning strikes and surges.
In general, effective grounding can be achieved with a grounding transformer as shown in Figure 1 (a). If the PV inverter has an internal transformer with the grounded wye to delta configuration, a grounding reactor can be used instead by accessing the neutral point of the inverter transformer.
Grounding helps prevent damage to electrical equipment, including solar inverters, in the event of a fault or electrical surge. It’s one of the most important reason of grounding a solar inverter. Proper grounding can help reduce interference and noise in the electrical system, leading to improved performance and reliability.
