High leakage currents from the PV array: This is a common issue that can be caused by damaged or worn-out DC cables, poor insulation, or an improperly grounded system. If the insulation resistance decreases, leakage current can increase, potentially leading to the inverter . . In wet weather, "leakage current faults" are more likely to occur than "PV insulation faults", and leakage current protection equipment is more commonly triggered which will cause the inverter to shut down. A likely cause is that the inverter is disconnected from the grid, entering the protection. . If transformerless inverters are used, so-called displacement currents can occur which are capable of tripping the residual current monitoring of the inverter or even that of the feed-in line. You'll learn what causes this fault, how it impacts your system, and the steps you can take to resolve it effectively. 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. .
