My question regards setting the charge current on the inverters.
EG. Axpert 5kva inverter has 4 x 12 volt 105 amp hour deep cycle batteries in series. charging should be 10 % of the amp/hour rating. so the inverter should be set to charge at 10 amps as the 4 batteries are in series.
add a 2nd bank in parallel ,so there are 8 batteries. so charging should be 20 amps. is that correct?
