How to troubleshoot photovoltaic panel grounding fault
If a ground fault is present, determine the location of the ground fault via the ratio of the two measured voltages and eliminate the ground fault. . A ground fault in a solar PV system is one of the more common array issues to come across, especially in string inverter and commercial systems. This test should only be performed by qualified personnel. DC systems can carry lethal voltages. The exact procedure is described in the following sections. If the voltage measurement was not successful, check the PV system. . According to the Photovoltaic Systems textbook (published by NJATC), a solar PV ground fault occurs when current unintentionally flows through the grounding conductor. It can often be challenging to determine which test will provide the fastest and most accurate results.Read More Download PDF
