Re: [RE-wrenches] 5 battery strings

Hello, I was called to repair a system. 24 volt 8 strings of Group 31 AGM batteries. I had not self-destructed yet. For the repair, I insisted on the strings being on individual breakers of 20 amps on equal length #12 wire to balance the charging. This is a battery backup system. I recommende

Re: [RE-wrenches] 5 battery strings

Separate out the individual series strings and run each string to a buss bar setup. Remember it isn't just resistance differences between batteries but resistance difference between cells as well. In a setup like the existing one the resistance differences can really add up and if one battery

Re: [RE-wrenches] 5 battery strings

I don't think its worth all that rewiring now to preserve an imperfect battery design that's probably only going to last a few more years anyway.  Just use those batteries up, and come in with a new single or double string of larger batteries. I know all of us wrenches would like to see amp ci

Re: [RE-wrenches] 5 battery strings

There will be troubleshooting with this design. Probably easier to use it up and redesign. If my name was on the inheritance, I would do it now or at the minimum fuse the strings. On Mon, 23 Jul 2018 12:26:32 -0400, Chris Schaefer wrote: And it's not a bad idea to add a shunt in each strin

And it's not a bad idea to add a shunt in each string for trouble shooting down the road. Christopher On Mon, Jul 23, 2018 at 11:24 AM, Steve Higgins wrote: > I would at least rewire them like this... > > [image: image.png] > Remember all the parallel strings take offs must be the same size/len

Re: [RE-wrenches] 5 battery strings

I would at least rewire them like this... [image: image.png] Remember all the parallel strings take offs must be the same size/length, otherwise you are going to exacerbate imbalance issues.

Re: [RE-wrenches] 5 battery strings

Dave Its a good idea to think of batteries the same way you do PV Modules. Any time you have more then two strings they get individual fuse protection, this is also good for diagnoses purpuses too. The current installation has no protection, safety and l would change it. As far as operation goes i
