We are building a system with (4) inverters on a roof with an AC combiner at ground level. The inverters have integrated AC disconnects, but the inspector is telling us that he requires an external AC disco at each inverter. The language in the 2014 NEC 690.15(A) specifically says that the integrated disco in an inverter satisfies this requirement, but it is not there in 2017 or 2020. Did it get moved somewhere or just deleted?
