Hi Kirpal,
With regards to your question about what size solar system will be feeding
this large battery bank, we are still trying to optimize the design a bit.
However, the the preliminary design was at about a 25 kW. During peak
production, we expect about 500A(!) to be heading into the batter

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 batterie
Hi Kirpal;
I see that the SBS batteries are rated to 1200 cycles to 80% DOD, but I
can't find the warranty on their website. Do you have a link to that?

Is this for an off grid system? We're doing our first project with a Deka
Unigy II battery system but they are AGM and I believe only good for grid

Consider the HUP Solar One battery, the 125-33. It has 2490 AH at the
20 hr rate. The warranty is for 2100 cycles to 80% DOD. Also most of
the jumpers are included (bus bars within each 12 v group)
We've had nothing but happy customers since we started using the HUPs.

Good point Jason. To clarify this is a 48V system.
Thanks

We've used these batteries in a couple
of high end off-grid jobs and they work great.
Yes, they are around 280 pounds..but by afternoon, they're
more like 325 ;-)
The last system we installed had 48 of these. And as Tump said,

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, Surret

Hi wrenches,
I am consulting on a job that requires an 8000 Ahr battery bank. This is
quite a bit beyond my normal battery bank realm. What would you recommend
for this?
Thanks in advance
