For your application, that battery seems like a great idea. I had a rep
from Michigan Energy Works drive all the way out to my off grid place in
New Mexico back in 90s to demo that inverter. Seemed like a good idea,
they just didn't have a good charge controller worked out for solar at
144 vdc at that time. I was actually considering their inverter to
provide onboard job site power on a 144 vdc electric vehicle we had built.

Thanks, Ray. In this case I established availability (albeit in SoCal)
and a good written price quote before posting my request here.

I don't see why it wouldn't have similar performance to other
Fullriver products. The problem I've had in the past, when I found
that "perfect" battery model on the spec sheet, is that the
distributor usually doesn't stock it, and then it either is too
pricey, or too long a lead time to be practical.

Esteemed Wrenches:
Short form, just my question: FullRiver makes a DC215-12 AGM
battery, which is in the J185 profile, more akin to an L16 at
15"x7"x15" tall. I haven't used this particular battery model and
it's not commonly used in solar applications. Is there any reason I
should avoid it, because of shape or intended application or
anything else?
Background story: I'm rebuilding/upgrading one of a handful of
late-1990s off grid systems that use the Michigan Energy Works
transformerless inverter/charge controller on a 144V DC voltage
standard. It's a rather unique product, difficult to make fully
Code-compliant today given the lack of an isolation transformer
between the DC and the AC. However, Code compliance isn't the issue
here. The existing system uses 24 6V L16 FLAs wired in series, with
a 900W array (10 BP590s from 1996) feeding them (at 5A max). I'm
adding 1,560W and reducing the battery capacity using FullRiver
AGMs. My question is simple: the most familiar large 12V AGMs are
the 8D profile with about 260 AH (C/20 rate) and sometimes the 4D
profile with about 210 AH. Both of these batteries are short, with a
larger footprint, and 12 of them won't fit in the space of the 24
L16s unless they're mounted on their sides. I can do that but would
prefer not to. FullRiver also makes DC215-12, which is in the J185
profile, more akin to an L16 at 15"x7"x15" tall. It fits the space.
Thanks, Allan
