Integral AC module grounding system

A photovoltaic (PV) ac-module grounding system includes a plurality of PV dc-voltage modules (34). Each PV dc-voltage module (34) is integrated with a corresponding dc-ac micro-inverter (32) to provide a corresponding PV ac-voltage module (38). Each PV ac-voltage module (38) includes an ac-voltage p...

Zusammenfassung:	A photovoltaic (PV) ac-module grounding system includes a plurality of PV dc-voltage modules (34). Each PV dc-voltage module (34) is integrated with a corresponding dc-ac micro-inverter (32) to provide a corresponding PV ac-voltage module (38). Each PV ac-voltage module (38) includes an ac-voltage plug and play connector (42) (43) that includes a dc ground conductor. Each dc-ac micro-inverter (32) is internally electrically connected to its own chassis ground or metal enclosure (36) which in turn is electrically connected to a corresponding dc ground conductor (60). A dc ground path (60) is carried through an ac power bus from ac-voltage module (38) to ac-voltage module (38) through the plug and play connectors (42) (43) via the dc ground conductors (60).
