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.

Why is proper grounding of a photovoltaic power system important?

Proper grounding of a photovoltaic (PV) power system is critical to ensuring the safety of the public during the installation’s decades-long life. Although all components of a PV system may not be fully functional for this period of time, the basic PV module can produce potentially dangerous currents and voltages for the life of the system.

Can a solar PV system be grounded?

Solar PV systems are still permitted to be grounded, per 690.41 (A) (1) and (5), and, for those PV systems that are, the dc grounded conductor is directly coupled (or coupled through electronic circuitry) to the ac grounded conductor, which is then brought to ground potential by being terminated to the neutral bus bar at the main service panel.
