Hi Kirk, See 2008 NEC 225.30 thru 225.40. As I understand it, separate disconnects, up to six for each array, located on the main building, are required and appropriate.
Dick Ratico Solarwind Electric --- You wrote: Hello, I'm working on a system which will have 5 kw on an outbuilding and 20kw on the main building, all Enphase inverters, I plan to put an AC disco for the 5kw on the outside of its building and another on the outside of the main building for the 20 kw array. Both arrays feed into the main panel in the main building. But now I'm wondering if I might have to combine the 5kw and 20 kw outputs so the outdoor disco on the main building shuts both arrays off. Any ideas here? I don't think the code addresses this clearly.
