6 FAQs about [Photovoltaic panel assembly grounding detection]
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.
Where should a grounded PV system conductor be grounded?
The location where grounded PV system conductors must be grounded is covered in 690.42. It states that a grounded PV array must be grounded at the ground-fault protection device—and at no other location.
Are model-based fault detection methods effective in PV systems?
Additionally, the review emphasizes the significance of data acquisition and monitoring in PV systems for successful fault detection. The application of model-based fault detection methods in PV systems, while demonstrating efficacy, is not without its limitations.
Can a PV system use a fuse as a ground detector?
In general, PV systems that use a fuse as a ground detector have a very low impedance path to ground at the inverter, making the problem observed in Europe extremely unlikely for PV systems with a fuse as a ground detector. Figure 8. Monitor in external enclosure Figure 9. PV output circuit combiner equipped with residual current monitor
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.
