Battery Charging Problem ***UPDATE***
While dry camping in freezing weather, the charging system died for the dual type 24 house batteries (2002 Winnebago Mini). It appears to be a solenoid system. It failed two years ago and the RV s...

Log,
I covered that earlier in the thread. When demand from the bank reaches 0.5 amps per 100 amp-hours of capacity, many AGM batteries are full. It my case that works out to approximately 2.9 amps.
I recently stopped being full time. So the solar system (blue sky MPPT controller with temperature compensation) will show 0.0 amps of charging after a week or so.
My choice of device would probably be a "smart gauge", which is the only charging system I'm aware of that adapts to the real capacity of the battery bank.
As I've only had 3 sets of batteries since I started RV'ing, I'm not likely to get more technology.
But in 2009 dc to DC charging devices were an arm and a leg and your first born child as far as cost goes. So I stayed "old school" with low and slow charging.
I love the Solar and it has paid for itself many times over.
