Six Basic steps to solar panel fault finding. Check the solar system performance data on the app and website, if available. Check the solar panels for dirt, leaves, mould, or shade issues. Check the solar inverter for any warnings or faults. Check that the isolators are all on and that the circuit breakers have not tripped off.

DC ground faults are the most common type of fault in PV systems and half go undetected. A DC ground fault is the undesirable condition of current flowing through the equipment grounding conductor in the circuits carrying DC power (before the inverter). Ground faults can lead to significant safety issues, such as arc faults and, in the case of .

If the PV and DC wiring is only rated at 600V, use the 500V setting to test. If the system uses panels and cable rated at 1000V, even if it is residential, it is suggested to test at 1000V. The reasoning is simple; a fault may only occur at voltages higher than 500V on cold bright days in a 600V system.

Troubleshoot an isolation fault. The next sections describe how to identify the source of an isolation fault if Error 2x19 or 8x58 is displayed. You can troubleshoot the isolation fault using the Inverter diagnostics screen in the LCD display, the Status screen in SetApp, or using a Megger tester.
