It is often notated as R iso (Resistance of Isolation). It can be thought of as a measure of how well the electrical components are insulated from each other and from the ground. . What are Ground, Isolation (ISO), RISO Low and Insulation Faults? These faults are often identified by solar inverters which will refuse to startup when they find them; sometimes they clear themselves only to reappear again at a later date, this can sometimes be weeks or even months later; other. . PV ISO PRO means the resistance in DC side (solar) is too low on one or more strings. The ground fault will need to be resolved before the system can be energized. or the inverter will be damaged by it. PV ISO-PRO01 - Negative wire is connected to ground PV ISO-PRO02 - Positive wire is connected to. . In photovoltaic systems with a transformer-less inverter, the DC is isolated from ground. Modules with defective module isolation, unshielded wires, defective Power Optimizers, or an inverter internal fault can cause DC current leakage to ground (PE - protective earth). Such a fault is also called. . Inverters constantly measure the value of the 'insulation resistance' between the solar panels and the earth. What exactly does this message mean? Error message on the inverter display or in the monitoring with a text such as. . This happens when a current-carrying conductor in the PV array makes an unintended electrical connection with the equipment grounding conductor (see Figure 1 below). When a ground fault occurs, the electric current that should flow to the inverter or combiner box is instead diverted to the ground. . In this article, we discuss what low isolation resistance means, why inverters monitor it, and how to resolve a low isolation condition if one occurs. Isolation resistance refers to the resistance between the PV array circuits (DC side) relative to other circuits, particularly the protective earth. .
