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). . Inverter leakage testing is essential to ensure the reliability and optimal performance of PV systems in the industry. An undetected leakage can lead to system malfunction, decreased energy production and possible damage to other grid-connected equipment. Thus, depending on the device type, a portion of the alternating voltage amplitude arrives at the PV module. Such a fault is also called. . In this article, we'll show you how to locate a ground fault in a solar PV string using only a multimixer, a basic understanding of voltage behaviour, and a method proven in real-world installations. This test should only be performed by qualified personnel.
