It's time to replace the 12Kw (never really was) FLA system in my RV that I built 5 years ago. All I'm getting is 2Kw before the voltage is 12.1V. I used to be able to go 2-3 days using 1kw/day when there was no sun but now the system needs to be charged everyday with a generator.
I build the system with 8-6V that are spit into 4 sets of 2-6V with a disconnect, 200A fuse and 4/0 identical length cables to each bank.
Componets are:
1.3Kw (panels in parallel) roof top solar Victron 250/100
1.3Kw portable solar Victron 150/100
Midnight Solar breakers/disconnect for roof top solar
3000W Victron Multiplus (110V pass thru) Inverter
600W Xantrex Inverter
Victron BMV-712
Victron Color Control GX
Pronautic 50A programmable (back up) charger
Honda 2000w Generator
The RV is used in temperatures down to 0F. At that temperature the battery box will be +/-15F. Probably get warmer since venting will not longer be needed and there's room for insulation.
Easiest route would be to buy 4 - heated 100Ah Lithium. I'm thinking BB for the warranty and heating when there is no charging.
What are the options (cells and BMS) if I build a 5kw lithium bank(s) myself? One of Two banks or split it into four banks?
