power converters, and beyond.....

First thing noted is that you have group 24 batteries and one is failing/failed. I wouldn't bother replacing with the same. Group 24, especially a Marine Hybrid. It is way down the pecking order in capacity for anyone going off-grid. The best bang-for-the-buck I've found is 2 X 6V GC2's from Sam's Club or Costco. I bought a pair two years ago for $190 out the door with tax and core charge included. Pricing remains similar. That will give you 205-240 amp hours of capacity, a good amount for an RV'er with typical power needs. If you invert the 12 V to 120 V (very useful) and have a wife that needs to use hair dryers, curling irons, and brews coffee through a Keurig, you will need even more capacity.

I use solar for 99% of my battery charging. I also invert to 120V for running a 120 V fridge and entertainment devices (TV, stereo, disc players). Solar does a better job of charging my batteries then I can, manually. I believe it's also better than any converter/charger.

I still have the original Progressive Dynamics PD-708 30 amp converter in the rig. The adder circuit board charger-modification tells me that the 708 is at least 44 yrs. old. If I was buying another, it would be from Progressive.
