6 FAQs about [Neutral line of photovoltaic panel]

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.

Does a photovoltaic system have a DC grounding system?

Photovoltaic systems having dc circuits and ac circuits with no direct connection between the dc grounded conductor and ac grounded conductor shall have a dc grounding system. The dc grounding system shall be bonded to the ac grounding system by one of the methods in (1), (2), or (3).

Can ungrounded PV systems be used with isolated inverters?

Most PV systems in the United States use isolated inverters with internal transformers (isolated inverters in the ROW) as of 2012, but non-isolated inverters and ungrounded PV systems are being certified/listed and are making market inroads. Note that ungrounded arrays can also be used with isolated inverters.

Are photovoltaic power systems safe?

Photovoltaic (PV) power systems are capable of producing hazardous voltages and currents for decades. To ensure the safety of the public for these extended periods of time, PV systems must be properly designed and installed using the highest standards of workmanship.

How does a utility verify a photovoltaic system?

The utility will only permit the photovoltaic system to interact with the power grid after issuing a formal approval. The process through which a utility verifies a solar system's compliance with its technical and administrative requirements is commonly referred to as the interconnection process.

Does a PV array need a grounding conductor?

Since the PV array and other electrical equipment in PV system, e.g., inverters, are often located remotely from one another, 690.43 (B) requires that an equipment grounding conductor (EGC) be run from the array to other associated equipment.
