Bus Bar sizing for 12 new Lithium Batteries?
I've got 12 new 100Ah Lithium batts being installed in an coffin style batt box and just figuring out bus bar or cabling size to parallel all 12 batts. Each battery has the potential for 100 A max charge or discharge.
I have used a serve rack WITH 600A rated bus bars to install 6 of the same batts in the past. I would just use two server racks but would like to utilize the existing batt box and all 12 of the new batts fit into the old box nicely.
I am debating on using two lugs/ cable on each batt terminal and using cable for the bus bar or finding a long 10 feet plus tinned copper bus bar?
I am using one 100A 600V Schneider Controller with the XWpro.
Do I really need to have the bus bar/ cabling be able to handle 1200A (12 batts) and 100 A (max charge amp from controller) and another 100A coming from the XW when the gen is running. Total 1400A of max possible current........
If the 12 batts are running through one 250ADC breaker would that really be all that the bus bar/ cable would ever actually see?
Just hoping for some dialogue on the subject...........
