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. Unlike hard, or active, faults, intermittent faults often only appear under specific conditions—wet weather, thermal expansion, or even tracking array movement. This report provides field procedures for testing PV arrays for ground faults, and for implementing. . Now all of a sudden the panel starts tripping. Not only is it annoying but it also indicates something wrong is going on in your system. Circuit breakers can trip mostly due to high current flow, bad quality circuit. .
