How to find and repair ground faults in solar PV systems
Not all systems will require insulation resistance testing to identify the array segment with a ground fault. For example, utility-scale systems with string inverters rarely have combiner boxes. Their DC PV circuit strings are run individually directly to the inverter. For these systems, you can skip insulation resistance testing.
