I'm not sure about the price, but what about using the DC enclosure from an
Outback Flexware system? Lots of space for branch circuit breakers, plus a
big DC disconnect.

I like the Midnite MNDC series.low
cost, with lots of room for future expansion.
List price around $225
I like Maverick's suggestion of using a combiner box, even lower
cost.

On the cheap side, Square D QO. They are indeed rated to 48VDC, which means
you can use them with a 24v system (but NOT a 48v system). If there is an
inverter too, the Midnite mini-panel ($160 with main breaker) and DIN-rail
DC breakers.

Happy Friday, all~
Allan Todd were discussing the issue where a reset type amp hour
battery monitor (such as TriMetric) never gets to reset to full when
operating on a GTWBB grid tie with battery backup system...because the
battery stays in float and the monitor never sees a bulk charge voltage.
Great ideas. I think for this job I will use the combiner box idea. I do have
an old trace disconnect box as mentioned laying around that would work as well.
Since I'm only putting in a couple DC lights, the combiner method should work
great. I get a lot of fish house and hunting shack
Thermal wrenches,
I have a series of upcoming projects involving large (up to 10,000 gallon)
water storage. They are closed (air-tight) but unpressurized (oversized
expansion capability) systems, basically just a mass of water. We move heat in
(solar, masonry heater) and out (DHW, space
We just finished installing a system on SolarMount and the client is
unhappy with how the ends of the SolarMount rail look. She says it looks
unfinished and is concerned about bees nesting in them. I know there are
other rail products with more finished looking ends but this system is

actually this is not the problem i have with amp hour meters on grid tie with
battery systems.
a floated battery does not need an occasional bulk charge. it is being float
charged which compensates for any internal self discharge. the only thing
needed is an occasional eq to stir the
The problem with many of the suggestions, is that these Micro 12 v systems
generally have budgets under $1000 parts. 20% of the budget allocated to
breakers and discos isn't reasonable, same with a Trimetric.
The ATC fuses are used for literally billions of 12 v circuits that all of you
use
I second using QO load centers. You will want to put a fuse, like an
FRN-R, between the battery and the load center, as the QO breakers
don't have a high AIC rating. 12 V systems can be wired as easily as
a regular AC system.

The QO breaker has an AIC of 5000 amps. The usual golf cart batteries have a
short circuit current of about 2000 amps, so you could do a set of 4 golf cart
batteries at 12v, without worrying about the extra fuse.
Once again, if the system gets any bigger, they should just go to an inverter
The code compliance part has been my worry. The small DC system seems to be
full of code problems. I do see the benefit of the DC only for the fish houses,
but the hunting shacks make me always think code. I have used the morningstar
