APC Symmetra 12KVA Power Array

APC Symmetra 12KVA Power Array

Hello All,  I just recently purchased APC Symmetra 12KVA Power Array.  The problem is I purchased it from Ebay, this system came in with out batteries.  Does anyone know what type of batteries go in the APC SYMBATT Pack?  PLEASE HELP!!!!! Greatly appreciated!

I have an older Symmetra 8Kva, with a 2nd cabinet.
In this, the battery modules are white, not stainless steel.
Inside the modules (I have 6 total) are 10 each 12v 7Ah SLA batteries, wired up as 120V DC. So now all I have to do is find a cheap deal on 60 standard SLA's.

I don't know if the newer LX or PX use the same construction inside the battery module, but it is very likely. Certainly the Symmetra RM documentation states the modules are also 120v DC.

Yes, you should be careful with all that stored power. In my experience, though, the battery modules are well built and intended to be refurbished. With care you can remove and reassemble with new SLA's.

One practical note I can pass on. Make detailed diagrams of the wiring as you take it apart. All I can say is, it's a good thing I had six of these to practice with.

Good luck.

It sounds like you had alot of experiance reverse engineering your System. Do you have the wire diagram and the Batt SLA number. I may have a good source that can help you get the batteries cheap!

Make sure you wire the battery modules properly.  Not just polarity but there is a battery connection midway through the string that must done properly otherwise you will get an alarm and it will trip your system to bypass.  

Good luck
