<div class="moz-cite-prefix">Hi Jesse;<br>
<br>
Midnite's breaker boxes would solve your disconnect issue, but I
wouldn't use the baby box or Quad box, they're small and tight.
I'd actually consider their 6 position combiner box, even though
its outdoor rated. Another option would be the Mini DC box. <br>
<br>
Here's my quick, real man's guide to many of Midnite's DC boxes:<br>
<br>
<u>Baby Box</u> Good for a couple of circuits, don't go over #10
wire. <span class="moz-smiley-s1"><span> :-) </span></span><br>
<br>
<u>BIg Baby Box</u> Good for a couple of PV inputs, and up to #6
for one Controller output.<span class="moz-smiley-s1"><span> :-) </span></span><span
class="moz-smiley-s1"><span> :-) </span></span><br>
<br>
<u>QUAD Box</u>, same size, only uses panel mount breakers. Don't
be fooled into trying #4 with this. It works, but you'll never do
it again. Keep it to smaller wires, and/or less than 4 circuits,
and you'll be happy.<span class="moz-smiley-s1"><span> :-) </span></span><br>
<br>
<u>MNPV -3</u> Outdoor Combiner box, good for up to 3 PV
circuits. a bit more room than the QUAD box, so it can actually
handle #4 more readily.<span class="moz-smiley-s1"><span> :-) </span></span><br>
<br>
<u>MNPV-6</u> outdoor combiner box. This one is a real
workhorse, and can be used with bigger wire, and separate
controller circuits.<span class="moz-smiley-s1"><span> :-) </span></span><span
class="moz-smiley-s1"><span> :-) </span></span><span
class="moz-smiley-s1"><span> :-) </span></span><br>
<br>
<u>MNDC-15</u> An overpriced POS. It can't take full size
bussbars, it can't mount a shunt, it has cumbersome breaker
mounting brackets that prevent you from being able to tighten the
breaker connections..... Sorry Midnite, but this one needs to be
totally redesigned and have a serious price reduction too.<span
class="moz-smiley-s2"><span> :-( </span></span><span
class="moz-smiley-s2"><span> :-( </span></span><span
class="moz-smiley-s2"><span> :-( </span></span>an absolute
black mark in an otherwise stellar line up.<br>
<br>
<u>MNDC</u> this box is awesome for all sorts of projects from
small inverter disconnects, to multiple controller and DC
disconnects. I've used this one for many years, and prefer it
over the E panel in certain budget cases.<span
class="moz-smiley-s1"><span> :-) </span></span><span
class="moz-smiley-s1"><span> :-) </span></span><span
class="moz-smiley-s1"><span> :-) </span></span>(its under
$200!)<br>
<br>
<u>E Panel</u> probably the best single inverter solution
available. No other box takes less wall space. Combines AC and
DC all under the form of the inverter. Can be a bit confusing
because of the side mounted breakers, so I move away from this, if
I have a lot of weird stuff like multiple inverters, multiple
controllers, DC loads, etc. However, Its actually better than any
of the inverter manufacturers' own equipment for single inverter
systems, and really comes with everything you need (breakers, AC
and DC adapter covers, prewired AC and DC cables, shunt, AC/DC
bussbars, etc.)<span class="moz-smiley-s1"><span> :-) </span></span><span
class="moz-smiley-s1"><span> :-) </span></span><span
class="moz-smiley-s1"><span> :-) </span></span>I've
happily used this for Magnum, Outback, and Xantrex/ Sheitdner.<br>
<br>
Good Luck,<br>

<div dir="ltr">Hello,
<div><br>
</div>
<div>Looked at a system today that consisted of the following:</div>
<div><br>
</div>
<div>15 - Kyocera 158W modules</div>
<div>3 - Kyocera 185W modules</div>
<div>1 - Outback MX60</div>
<div>
8 - New Trojan L16RE (48V system)</div>
<div>1 - Xantrex SW Plus </div>
<div><br>
</div>
<div>
<div>6 months ago he swapped out his old charge controller to
the new MX60 and purchased the new batteries at that time.
The array wiring did not change and is wired in 6 strings
of 3. (confusing to the MX60?)</div>
</div>
<div><br>
</div>
<div>He is now adding 4 Kyocera 240W modules. He also purchased
another MX60 for this array.</div>
<div><br>
</div>
<div>From my perspective, removing the 3 185W modules and
getting them on their own controller would be a better use of
the modules. The system currently does not have any
disconnects on the PV side. There are fuses in the combiner
boxes on the array, but no disconnects inside at the charge
controller. So adding 3 charge controllers, and now needing
to add GFDI, means a box of some kind needs to be added to
house these breakers. </div>
<div><br>
</div>
<div>Outbacks GFPs and panel mount breakers will work, but what
is the best mounting solution for these? One DC Flexware
enclosure? It will of course allow for all the DC OCPD and
allow for the landing of the output of the charge controllers.
Or is there another enclosure/OCPD solution I should look at?
