In this article, we'll address the issue of “leakage current protection” errors in inverters, a common concern for solar PV systems. You'll learn what causes this fault, how it impacts your system, and the steps you can take to resolve it effectively. Understanding. . Leakage current failure: faults and possible causes as well as ways to prevent the issue. 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. . The issue of leakage in photovoltaic energy systems is controversial and you will find a large number of professional opinions on the subject. Some recommend completely ignoring the matter, while others do recommend monitoring the phenomenon and executing a systemic solution once every few years. . 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. Contact a qualified professional to diagnose the extent of. .
