<div>While I haven't completely convinced the latest inspector about PV not being mechanical equipment, I'm running into another issue. <div><br></div><div>I decided to try out the new Midnite MNPV6-AC combiner for Enphase circuits. 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. </div>
