OK I have had the original charger inverter power supply working and the AGM battery is charging just fine. The problem I am having now is that the if I am running my A/C and my Microwave on shore power sometimes either or will trip the breaker. I just think the whole power supply unit is old and needs replacing. It is a Parallx 7300 Series power supply. I am thinking is it possible to change to a 50 amp supply instead of the 30?
One other question. Do these new supplies come with a fan for cooling the unit? The current one to my knowledge does not.
The 7300 will chronically undercharge the AGM batteries.
Get a Progressive Dynamics replacement converter. If going 50 amp... may as well get the full 50 amp Progressive Dynamics load center. Only hard part might be pulling new 50a NMB cable from the entrance to the new panel. If access is easy it will be a slam dunk.
