Your inverter does not appear to supply it (smaller inverter-only units often don't). You will probably measure significant AC voltage between G and N at the inverter. . A ground fault in a solar PV system is one of the more common array issues to come across, especially in string inverter and commercial systems. Assuming I have to ground the breaker box--how can I do that? It's the safety. . A solar inverter doesn't “see” a ground fault the way a human does. 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. . My inverter has DC inputs and a ground connection (currently bonded to my ground busbar which connects to a ground rod). For outputs, it has 2 AC outlets as well as a terminal AC block (with Live, Neutral, and Ground outputs). The electrical insulation from the PV system to ground is defective or insufficient.
