Because there are overcurrent devices inside, the inspector now insists that NEC 240.24(A) applies and that the enclosure must be readily accessible, meaning you have to reach it without a ladder. That would seem to make the MNPV6-AC as a roof mounted solution, or Soladeck combiner boxes, or any other combiner box incorporating overcurrent protection, pretty much useless on a pitched roof or flat roof without a permanent access ladder or hatch.
