Hi Steve S
I'm new to this forum. Comfortable with sorting electrics but LiFe technology is new to me.
Retired aboard my Catamaran and currently hiding from hurricanes in Chesapeake Bay
Based on your write-up I just placed my order for 24 x 280Ah Xuba cells to replace my gel bank (24V 800Ah) - thanks.
Did not think about buying bussbars
- will try get them to add to order.
Quick background on inputs;
2 x Victron 5000 24V multis + 1 x Mastervolt 24V charger - each 100A charging capacity with LiFe settings.
5 x solar arrays via Victron MPPT's - 3400W total
2 x 120A 24V auxiliary alternators with MasterVolt controllers
2 x Eclectic D400 24v wind chargers
"normal" power draw is 20A /24V - 14kW per day
Maximum power draw is 500A for max 1 minute (bow thruster)
Questions / advice / comments please
Does it make sense to set up 3 banks of 8 cells each so that each charger will work independently? Given that they will all connect to the same output busbar anyway, not sure how to achieve this or whether its even necessary. Further complicated by solar/wind/alternator inputs.
Any recommendations on BMS? Presume 3 x 8s 150 Amp in parallel? Would be nice if the BMS units communicated with each other too - so that all 24 cells stay balanced. Not sure what the BMS Amp rating refers to (input, output or both?)
It has been suggested to me that I use a Victron Cyrix Li-ct 24V 230 A on my alternator inputs - alternatively Victron Battery Protect 220A?
Can you think of any other protection "gadgets" I should add?
Any input will be welcome
Thanks
