6 FAQs about [Measurement method of photovoltaic panel grounding]

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.

What is a ground fault in a solar PV system?

This Solis seminar will share with you the causes and troubleshooting methods of PV system ground faults. In a solar photovoltaic system, if a ground fault occurs, the inverter will display a “GROUND-FAULT” alarm when it starts running, and the alarm code is 1033H.

What is a grounded PV system?

A PV system is defined as a grounded system when one of the DC conductors (either positive or negative) is connected to the grounding system, which in turn is connected to the earth. The conductor that is grounded usually depends on the PV module technology.

What is electrical & PV grounding?

Before discussing the subject of grounding, the term “grounding” requires definition. There are two types of grounding in electrical and PV systems—equipment grounding and system grounding. Equipment grounding is known in the ROW as safety grounding or protective earthing.

Do I need a grounding electrode for a PV array?

While a separate grounding electrode system is still permitted to be installed for a PV array, per 690.47 (B), it is no longer required to be bonded to the premises grounding electrode system. In PV systems with string inverters, the equipment grounding conductor from the array terminates to the inverter’s grounding bus bar.

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.
