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. . It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. DER units with AC nameplate capacities from 100kW to 10MW are. . Conventional generators are considered to be voltage sources as they provide constant ac voltages controlled by excitation systems. In contrast, a grid-tied inverter-based PV plant is modeled as a current source whereby the plant's terminal voltage is dependent on the feeder. In most cases, the GFPD is a fuse ated at 0. Figure 1: Example of a grounding arrangement on the AC side. Utility companies often require. .
