<div dir="ltr">Oh, yes - that is a great application for the MNPV-AC. I didn't mean to imply there isn't a good use for them. In this particular instance the three MVPV-AC's are really subcombiners that get all get tied together in another subpanel at ground level. They really were not necessary, but made it more convenient and cost effective.<div>
<br></div><div>It's just interesting how Midnite advertises that they can be mounted as flat as a 3:12 pitch. What application would allow this mounting angle where it is still readily accessible? The spec/advertising seems to imply that these can be roof mounted in an AC string combining application.<div>
<br></div><div>The Soladeck combiner with fuses would appear to be non-code compliant in any situation. I would love for someone to refute that in a convincing way given the access requirements in 240.24(A).</div><div><br>

<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>
