Dick, Thanks for your take on this. The problem I see with using the existing AC/DC system GE for the PV GE is that the EGC will run in parallel with it, separate, but connected at each end (at the array and at the GE). This could set up a ground loop and still leaves the electronic imperiled.
I think that, if the dedicated, PV GE is required it should NOT be bonded to the other system GE's. If it is not required, the PV GEC should NOT be used. What are you Wrenches being required to do? I"m wondering how other AHJ's are seeing this. This is the first AHJ in our area to bring this up. -Kelly Kelly Keilwitz, P.E.
