I have a job with Enphase microinverters on a detached garage. The IQ Combiner panel, which requires a neutral, is on the house. The solar panels are on the detached garage where they land into a combiner panel. The micros do not require a neutral to function so I never pull one in these situations. I've been given the OK to do so by the state of MN (2020 cycle) but this job is in WI (2017 cycle) and the inspector says I have to pull a neutral to the garage. She's citing 250.20(B)(1) and I tell her that the combiner does have a neutral but I don't need one at the garage as it will have no purpose, it just floats.
How is this any differetn than electric heat or EV chargers that don't use a neutral? I'm looking for more ammunition to fight back, any help would be greatly appreciated.
