Hi jason, 3 questions, I can't find the MNPV-AC in midnites price list, is this something custom or just new? And if you don't need breakers why not just do a junction box on the roof. and the inspectors I've had have requested a disconnecting means on the roof or visible from the roof. So I've done the enphase suggested switches on the roof, but no overcurrent. It doesn't appear that is a requirement from your inspector?
