[RE-wrenches] Huge battery bank recommendation

[Kirpal Khalsa]

Mac...good morning....that is a big battery bank!....We have used the SBS
Batteries for large battery banks....They offer multiple warranty options
including upto 20 years.  They are tubular plates with clear outer cases
which make the electrolyte levels really easy to monitor and fill....They
come with insulated cell interconnects with testing ports, they offer
seismic racking custom designed to fit your battery bank, as well as spill
containment trays and acid neutralizer kits for the spill containment
trays.  We have been very happy with their performance.  They offer a 2V
FLA cell at 4000Ah @ the 20 hr rate.  They are a high quality product made
in the USA and worth looking at.
Here is the link to their website.

Additionally they offer hydrogen gas alarms for battery rooms.

I am curious - is this a solar integrated system, if so, what size array
would be charging the batteries?
Good luck!
