One time we built the wall out to bring the equipment in to compliance
with the front of the battery enclosure.

This isn't just a Li+ issue, this has been a problem going all the way back to the 90s. Basically many AHJs don't catch it, but its still a violation. We either keep the battery cabinet shallow, or we put the battery cabinet to the side. Just use some common sense, if you are having to lean awkwardly over or around something to get to the breakers, its probably a violation.

I'm reading that the working space must be down to the floor/grade with the exception of other equipment extending up to 6 inches deeper than the enclosure for which the working space applies.
For example, technically you can't put a 32 inch deep base cabinet and countertop below a load center. I see it all the time, but inspectors around here in some jurisdictions will not allow it.
I seriously doubt I would be flagged for a 24 inch deep battery enclosure below a 12 inch deep inverter with integrated disconnects, but by the book it seems like a violation.

l dont know that this NEC code applies in the way you are reading or understanding it, I do see where foreign components are restricted with in the space. We have systems with two or three outback radians above blueplanet batteries and have not seen an issue. The BPE's are in an enclosed cabinet fire approved and protected from shock, putting batteries further away will create space issues. Since all of these components are required for the "system" to operate they are necessary.

I'm seeing a lot of pictures of LiPO battery systems and people are mounting equipment above them like load centers, inverters with disconnects, and other serviceable enclosures. Some of these battery systems are 24 inches deep or more. This seems to violate NEC 110.26 requirements for the other serviceable equipment, but the pictures are proudly displayed as models of success. Even slender Tesla Powerwalls stick out significantly when stacked 2 or 3 deep and would be more than 6 inches deeper than a standard load center. Sure, the battery cabinets make great places to rest tools while working, but does anyone else see this as problematic?
