[RE-wrenches] Huge battery bank recommendation

[penobscotsolar at midmaine.com]

Mac, for this type of large system we typically use Surrette/Rolls
2YS31.They are 2430 ah. When we get into battery banks this large we
typically only run two cells deep (front to back) for ease of maintenance.
I hope your customer has some free time on their hands for maintenance.
Remember, Surrette deep cycle batteries demand a higher than most charge
rate or you will find the life of the cell will be significantly shorter
than with proper charging. I'm sure your local battery distributor or
Jamie Surrette can send you the tech stuff on these batteries. Any way it
goes, this is a very big battery bank. Good luck!
