In the lifecycle of a Photovoltaic (PV) plant, "Low Insulation Resistance" (ISO Fault) is one of the most common inverter error codes. With global PV capacity hitting 1.
[pdf] Connect the L (line) side of the tester to the photovoltaic cell string's P (positive) side. Measure the insulation resistance at the P-side terminal and check for any signs of degradation. The exact procedure is described in the following sections. It usually signifies damaged cable sheathing, moisture ingress in junction boxes, or a compromised module backsheet. In case your inverter displays an earth fault (E34 Insulation), be aware that an isolation error is a severe risk which can result in fire or electric shock.
