I've just added my third bank to my project and better document it for the cell counter list!
My system started over 12 months ago with the intent to replace my inefficient SLA battery bank.
The build was based on the You Tube videos by UK DIY Powerwall - one of the first to start this idea going.
It is a 24v (7s160p) bank that is tended by a SMA Sunny Island 3324 ac coupled power converter controlling a SMA SB-2500 solar inverter connected to 2kw solar panels on my shed roof.
My battery box was surplus SLA battery backup cabinent which determined the size of the build as 7s160p using a 8 by 20 grid.
I have been a bit unconventional as I didn't adopt the "wall' approach and have used heavy busbars with the sub-bars being 6mm cable and not copper strip. I also have mini voltmeters on each cell as well as the excellent Batrium BMS.
Cheers !
