Never laid on my stomach, I just have kneel pad I use for lots of stuff
but it works good here too. I never get my face that close to the
battery any way. Usually 2 to 3 ft is good.

Article 110.26 covering clearances in front of electrical equipment
applies. I worked on a couple like that, and I didn't like it. Very
hard to move the batteries, and Combined with H2S, you are in what
OSHA considers a confined hazardous space.
Another way to use that crawl space is to build a trap door access
from the floor above. This can work really nicely, and put the
batteries right under the inverter without violating article 110.26.
I think I saw a system that either Allan Sindelar or Windy Dankoff did
like that. I've tried it a few times, and everyone (customers and
inspectors) was happy. Here's a pic of some HUPs in a floor vault just
below the inverter:

Safe working clearance is 6’-8”.
I have been confronted with this issue in the past taking over
other’s systems care. This is a head banger & a major safety issue
if something goes bad. If the batteries are 18-20” tall that only
leaves anther 28-30” between bottom side of the floor joist & the
top of the battery. Your face is way too close to a battery esp.
if there is an issue to address.
The installation is bent over back-heavy move situation. I am
assuming you have a dirt or gravel floor to move across?
It seems like a good use of space up front but the reality of the
install plagues you down the road.
If it is WLA batteries it is the worst of situations.
Even if this is not inspected, please avoid this situation.

*Subject:* [RE-wrenches] Batteries in 4' tall crawl space
Wrenches,
I have a customer who wants to have batteries installed in a 4'
tall crawl space / short basement. Are there any accessibility
code issues with installing batteries in a crawl space? Does the
NEC address this?
Thanks,
Jerry Caldwell
