I'm rethinking the 12 volt system on Stella and still new to all this.
Currently we have three battery banks and a Xantrex Truecharge2 40. There are two 8D AGMs in both of the main banks. Each of these banks independently starts one of the mains and also serves house loads. The third "bank" is a single 8D AGM for the genset exclusively (which seems like overkill). The 4 engine/house batteries--which are dead--have (had) 980 amp hours combined, which seemed ample, and tons of cranking amps. The genset AGM still has some life left.
Each of the three banks appears to be independently charged by the Xantrex.
I'm not completely comfortable with the Xantrex, both from things I've read and due to swelling of the AGM cases that may be due to overcharging. So I'm thinking of replacing it with a Magnum MS 2812 inverter charger.
It appears that the Magnum only charges a single bank. (True?)
I'm virtually certain I'll stick with AGMs but might go with easier to handle 6-volt AGM golf cart batts for engines and house. The two main banks, in their original Defever configuration, are outboard of each engine and I prefer to keep them there (except when it's time to move them).
Assuming the banks stay where they are physically, what would be the optimal configuration electrically? Am I looking at a new Magnum plus a separate charger or battery combiner or something else? All ideas much appreciated.
