I saw that also. Is it 7" or 12" minimum clearance? The way it is worded. 7" meets fire code. But you need 12" for normal operation. So it sounds like 12" minimum. ???
Thank you both, timseletric and wpns, for your response. I think I understand both of your responses. And I agree that there is no motivation for a battery builder to make the certification test more difficult. It's sounds like a nail biting process as it is. I will plan accordingly.
As far as...
The shed is 72" square for the out side dimensions. I figure, by the time I insulate it. I will loose 6 more inches. Which brings me down to 66" wall width. It's actually one of those aluminum sheds that the railroad uses at crossings for their electrical equipment. All aluminum and critter...
With the lack of response. I will assume that in my circumstance that I need to have a minimum of 36" of clearance in front of the unit. So no back to back install. 🙁
Is there a requirement of minimum open distance in front of the batteries?
I live in Minnesota so NEC 2023 code. My potential power shead is 6' X 6'. I am hoping to place them back to back. (I see now that they require 7" spacing. )
Would something like this work. I just did a quick search and this is what showed up.

I do like the way fromport has separated the positive/negative from each other. Also, that they are on the "outside" of the pack. This can reduce the chance of shorting out the batteries when installing the cables.
It can also be slightly modified if you want the posts closer for running cables.
A couple more points to think about,
1)A 100w panel doesn't usually output @ 100%. I'd figure 80% (80w) at best.
2)Did you figure anything for ac?
3)Electronics don't run at 100% efficiency. Various efficiencies for various types.
It sounds like you are on the right path, and have a...
You could use something like this also. A little pricier, but would only need one panel, and could be under battery voltage. They do make one for lithium...
