6 FAQs about [Ground wire test for photovoltaic panel construction]

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.

What are the bonding and grounding requirements for PV systems?

The specific bonding and grounding requirements for PV systems in Article 690 are in Part V. Section 690.41 covers system grounding, allowing both grounded and ungrounded PV array conductors.

Does a grounded PV array need a ground-fault detector?

It states that a grounded PV array must be grounded at the ground-fault protection device—and at no other location. Since nearly all PV systems have ground-fault detectors in or at the inverter, the requirement is actually in the exception, which can be confusing.

How do you fix a ground fault in a PV system?

Replace all impacted equipment and conductors. Ground faults can be a persistent issue for any PV system. They take a toll on system health and productivity. A clear, consistent approach to finding and diagnosing such faults can help you repair them reliably and efficiently whenever they occur.

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.

What happens if a PV system has a ground fault?

In some cases, a ground fault will be easy to spot. High resistance generates heat, which may cause a fire and potentially extensive damage. Replace all impacted equipment and conductors. Ground faults can be a persistent issue for any PV system. They take a toll on system health and productivity.
