High leakage current isn't just an efficiency killer; it's the silent budget drainer that keeps solar technicians awake at night. But before we dive into solutions, let's break down why this sneaky issue occur. 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. In the former case, this causes the inverter to temporarily disconnect from the utility grid, after which. . 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). Some recommend completely ignoring the matter, while others do recommend monitoring the phenomenon and executing a systemic solution once every few years. . 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. broken busbar within a PV module).
