[RE-wrenches] FullRiver battery question

[Sindelar Solar]

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
