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

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
Jason,
It seems to me that two of the exceptions in 240.24 may apply to your
situation. Most significantly (4) For overcurrent devices adjacent to
utilization equipment that they supply, access shall be permitted to be
by portable means. Thus using a latter to access the ac combiner on the
Yeah, normally it would have been our practice to use a j-box and bring
down three strings. In this case it made more sense to combine strings on
the roof and just bring down a single circuit in a single conduit. Long
story... long wire run... probably bad planning in hindsight.
The MNPV6-AC is a
While I haven't completely convinced the latest inspector about PV not
being mechanical equipment, I'm running into another issue.
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
I'm with your inspector on this.

I assume you mean pitched roofs, or not readily accessible flat roofs. This
particular project happens to be a flat commercial roof, but with no
permanent ladder or hatch. I really didn't have to use the MNPV6-AC's, but
it made sense in this case (excluding the access issue).
Looks like my
Might be a good application for the Midnite Disconnecting Combiners, with
the control unit on the ground.

Hi Jason,
Is it possible to install them on the side of a building?
And Dan's suggestion for the remote midnite might be perfect.
