I have two Duracell 6v golf cart batteries from Sam's Club wired in series, and the old converter worked fine for my needs. How much better will a new converter be? I also plan on adding either one or two 24v solar panels with an MPPT charge controller, as well as a pure sine inverter.. How much will I benefit from a new unit? I see a deal on a Progressive Dynamics PD4635V.
The PD will charge at least 10x faster if you run a generator. PD will give a better maintenance charge and will better fully charge your batteries to avoid sulfation and perform better for more years. You can go bigger but if you do you need to review the wire size on the charging circuit and possibly pull new wire. 35 amps is plenty and allows use of a smaller 1000w generator if needed.
Solar will also get the batteries properly charged when the sun is shining. I assume you will have 400/500 watts and that is excellent for off-grid camping.
I recommend a smaller inverter of 150 to 350 watts. I like GoPower and Victron.
