Abstract
A photovoltaic (PV) ac-module grounding system includes a plurality of PV dc-voltage modules. Each PV dc-voltage module is integrated with a corresponding dc-ac micro-inverter to provide a corresponding PV ac-voltage module. Each PV ac-voltage module includes an ac-voltage plug and play connector that includes a dc ground conductor. Each dc-ac micro-inverter is internally electrically connected to its own chassis ground or metal enclosure which in turn is electrically connected to a corresponding dc ground conductor. A dc ground path is carried through an ac power bus from ac-voltage module to ac-voltage module through the plug and play connectors via the dc ground conductors.
