Leakage current of photovoltaic combiner box

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 ways this common fault can be prevented. Failure Occurrence and Cause. 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. .
