Re: [RE-wrenches] Huge battery bank recommendation

[Allan Sindelar]

Kirpal, I reviewed the link; thank you for this referral. I was surprised by the specified charge settings: while there's no bulk/absorption setting given, equalize is 2.33 - 2.40 vpc, or 53.5 - 57.6 v on a 48 v bank. This is what I would expect with VRLA batteries, not flooded, as it's barely skirting the edge of the gassing range. Is this something specific to lead-selenium technology? Is it unique to the tubular positive plates? Is it specified for industrial (regular recharge from grid) as opposed to "opportunity charging" typical with PV? Please help us understand from your experience with them.

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! Daryl DeJoy NABCEP Certified PV installer Penobscot Solar Design Good point Jason.  To clarify this is a 48V system.
