<div dir="ltr">Ray.....i do not have the link to the warranty....our salesman presented us with a variety of options ranging from 5 years upto 20 years.....just like other manufacturers they had prorating levels with each option.....If asked i am sure they will provide you with any information you want in regards to the warranty....<div>
<br></div><div>Allan.....yes in fact we were also surprised with the low voltage settings that they specify....In one system we installed a 3200Ah battery bank and trying to coordinate the settings they specify with the programmable settings offered in the Sunny Islands was an exercise in it self....They have different terminology than is common in most RE system charging parameters....making sure we were all talking about the same parameters was the hardest factor....If i remember correctly the absorb and equalize settings were almost the same per the manufacturer. </div>
<div>I could not tell you much about the lead -selenium technology or the tubular positive plates with any expertise.....</div><div>The large system we installed these batteries on was specified to use the longest possible life span batteries coupled with high cycling capability....At the time they were the only company we could find willing to put the 20 year warranty in writing apart from some sealed Unigy batteries which were far more expensive..This was a AC coupled grid interactive system and so the batteries are in standby 95%+ of the time....We have a contract to do routine maintenance on the system and have only had to add water once per year....even then it was not necessary but to set it on course till the next time we are scheduled to inspect, 1 year later. </div>
<div>The customer has had very few power outages but did have one for 4 days last winter and the battery bank worked flawlessly....We really like the clear cases for quick electrolyte level monitoring. The cells have flip tops for easy access. </div>
<div>My overall take on these batteries is that they are primarily designed for standby systems. We haven't used them in an off grid configuration. They have been in for 3 years with no sign of aging...I think they are a company that is only beginning to realize the possibility of the RE market and havent focused much effort in that direction in the past....</div>
<div>SBS was easy to work with, and provided good support for the seismic racking and spill containment system....with more documentation than i am used to receiving from our main suppliers...</div><div>Hope that helps...</div>

<div>Hi Kirpal;<br>
<br>
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?<br>

<div dir="ltr">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. </div>

<div>Additionally they offer hydrogen gas alarms for battery

<div>I am curious - is this a solar integrated system, if so,
what size array would be charging the batteries? </div>

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)<br>
We've had nothing but happy customers since we started using
the HUPs.<br>

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

Good point Jason. To clarify this is a 48V system.<br>

Not that I have an answer for you, but I'm

specify voltage to get a good answer.<br>

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