Powmr 5kw all in one controller/inverter settings help

[ChrisB1234]

Looks like I need another 48v 100ah battery then and add that to my current 48v (4*100ah) bank, Man those things are so expensive, might be cheaper to just buy another 4 100ah and a battery balancer

I guess 2.2kw of solar should be enough to charge that lot in full sun
