[RE-wrenches] Request for Enphase inverter comments

[Geoff Greenfield]

Thanks Marv (and thanks Michael W. for clarification).  

Marv - could you comment on the grounding requirements?  Am I correct that I can't just daisy chain inverter chassis grounds and land at a sub-panel AC ground bar? (and that this inverter chasis ground is in addition to the DC module frame/rack grounding we are used to?).



For a brighter energy future,
