Re: [RE-wrenches] GEC sizing for a high amp, low voltage PV system with microinverters

I think Gary may be overthinking this. If the micro-inverters have a GEC lug then you'll need to run a GEC. If you run your GEC to a ground rod, then you don't need to use one larger than #6 per 250.166(C). (note also (D) and (E) but they're less useful to you here) / Commentary:/ It makes
