In this episode, we will discuss “leakage current failure” faults and cover possible causes as well as ways to prevent the issue. We will look at a real-life installation example to demonstrate

The occurrence of leakage current that can occur in photovoltaic (PV) system depends strongly on the value of parasitic capacitance between PV panel and the ground.

The system voltage of solar panels drives a leakage current between the solar cells and the grounded metal frames. This results in many different forms of potential induced degradation, including

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

The problem here is that, the DC leakage current in the cables flows through its insulating material through ground, and this is often known as DC leakage. The faults in the DC side as well as
