How much converter/charger is really needed?
I have a pair of NAPA 9824M Marine/RV batteries with a 20 hr rating of 79AH each, wired in parallel. Is there, really, any advantage in going from a 45 amp (PD4645V) converter/charger to a 55 amp (...

From the OP's recent posts, it looks like he has a 2000w gen so can go to max of 75 amp converter/charger.
He also wants more solar as though going off grid more, which also means more gen recharging when not enough sunshine. He is also getting new batteries, since he said he can't get through one night on his exiting two older batts with the furnace up high enough to not freeze to death.
He is also a big PD fan, despite the existence of PowerMax! (Weird :) )
So, since the PD 70 amper can be run on a 2000w gen (just) and that is the right charging amps for about 225AH of bank, which he needs to run that furnace, and he will be off grid more---then it is clear:
-Get two Trojan 225 AH 6v T-105s ( or equivalent at Sam' or Costco)
-Get a PD 70 amper to replace the 45
-Get the extra solar
-Get a 300w or so inverter if not already in hand, so now you can run it off grid with the bigger battery bank and watch more TV/DVDs or whatever.
Too easy! :)
