Measure ground resistance of photovoltaic panels

This report provides field procedures for testing PV arrays for ground faults, and for implementing high-resolution ground fault and arc fault detectors in existing and new PV system designs.
Checking the PV System for Ground Faults

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. If a definite ground fault cannot be measured and the
