Hello,
I am looking at installing an 11 panel PV array using 250W Power One microinverters.
As an electrical design reference I have Enphase's sample wiring diagrams.
As far as I know, Enphase requires a GEC (Grounding Electrode Conductor) to run from the microinverters to a grounding electrode.
I am not sure about Power One Microinverters' requirements. Will an EGC (Equipment Grounding Conductor) that runs from inverter to inverter (and also to the panels) be sufficient? This conductor would run back to the main service panel's grounding terminal bar.
I cannot find any documentation that clearly shows what the requirements are. In Power One's manual it only makes mention of a EGC, which would indicate that no direct run to a grounding electrode is required.
Thanks!
