The inverter leakage current detection module detected excessive leakage current. Solution: Disconnect the PV input, restart the machine, and observe whether the machine can return to normal. . 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. . 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). You'll learn what causes this fault, how it impacts your system, and the steps you can take to resolve it effectively. Thus, depending on the device type, a portion of the alternating voltage amplitude arrives at the PV module.
