I know the NEC( dont have code book in front of me) required a DC grounding electrode and conductor to be landed on the designated DC grounding electrode terminal inside of the inverter. I've seen most larger 3-phase inverers have a designated grounding electrode on the DC side of the inverter.
What about a single phase inverter that only has one ground terminal? Do we use this ground terminal to land the DC grounding electrode? Do we use the same terminal to land the EGC from the upstream main panel as well?
Also if I have (3) inverters side by side, can I installe one grounding electrode in the ground and then have a grounding electrode that runs to all 3 inverter by means of tapping a main grounding electrode? I guess this would have to comply with the rules of article 250 for tapping a GEC?
