Just marking the territory in case anyone else discovers how not straight forward finding an answer actually is. I've searched this forum and found not much in regard to going from 12v to 24v.
The question (in question) is how does one charge a 24v batt bank from a 12v system.
The answer is RedArc's BCDC2420 charger.
E-trailer.com, RedArc's US distro, does not carry them. But I have a call in and they should have them on their website in a week or two. Their initial answer to the question was, "You need two BCDC12xx chargers, one for each battery, then arrange a disconnect method between the two batteries." Wholly or in part, this is not acceptable.
It is surprising how little there is out there in the way of addressing this seemingly simple need to charge a 24v bank of 2-12v batts in series from a 12v alternator/aux batt source.
No one else, best I can tell, has a device that does just this very thing - and also integrates a solar MPPT controller.
Admittedly, my realization of this could seem completely elementary to the 24v folks here. And for that I apologize. It's just that going out and searching for such a solution sent me down weeks of rabbit holes and half-solutions when I thought it would be pretty straight forward to find what I needed.
Cheers and happy trails!
