Hello wrenches,

We have a battery back-up / interconnected system utilizing PVX-2580L
Sealed
AGM SunXtender batteries. The battery bank will be located inside a
utility
room which is part of a large 2000 sqft underground garage.
The room has mechanical venting out into the garage. The garage has
8-10'
ceilings and a large double garage door that goes up to ground level.
It
also has a couple of doors to finish portions of the basement (wine
cellar,
maid quarters, Rec. room) and 2 stairways up to the first floor living
area.


Standard practice for us is to have venting but in this case the
basement
walls are ~16" solid concrete walls with no available openings for a fan
to
push air outside. We contacted the battery manufacture and they gave us
a
reality scenario where the chances of enough hydrogen to accumulate in
this
large of area to reach an explosive level is impossible BUT, they are
not
fire experts and we should consult with our local fire department for
guidance. 

If we have to we will core a hole into the foundation install a fart fan
and
ducting but, I wanted to get your thoughts before that fun job.

Thank you!
