It is all about generator time to recharge the batts. You need lots of amps. 25% charging rate is about right. ie 100a on 400AH capacity bank starting at 50% SOC to 90% in under 2.5 hours. 55amps would be ok with a pair of batts, but is not enough for four batts for fast charging.

OTOH if you only use the converter on shore power then time is not a factor, so a slow charge is ok. But then you don't need much battery either!
