Hi all, something to consider is charging those suckers back up once they are drained. Drawing down 440 ah to 1/2 way is roughly 200 amps of charge to have to gain back.
I am experiencing this now as we run 2 CPAP machines among other small loads while boondocking. I have 4 6v 240 ah batteries. I figured a 20 amp Xantrex charger would suffice. Well 200 amps equates to 10 hours to recharge the batts to full on the gennie. That is unacceptable. I am now looking at at least a 40 amp charger. Unless my napkin math is off.
