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 (...

Bobbo,
There is a lot that has been posted here and I am going to throw out another piece.
If you do not have a real battery monitor, don't do anything expensive. Now matter what you have available and far a charging, if the system won't handle it, it is a waste. So, look them up and install a Bogart or Victronic or other that can really tell you what is going on. These pretty much are essential to maintain a solar system anyway.
Very many times (too numerous to identify) I have found systems that did not have the cable to support the charging current that an owner had installed. Then, they call me because it does not do what they had hoped.
So, before you install more line charging capability, install a real monitor and see what it is capable of right now. You may need to add copper just to make what you have work as intended.
I did a whole lot of this stuff for sailors with performance cruisers (read retired race boats). Now that they wanted to be comfortable, the first thing that they wanted were better electrics.
