I have been thinking about installing a DC to DC charger to properly charge my coach batteries from my alternator while driving. I have a dual-output alternator that delivers a constant voltage of about 14.4 V to the coach batteries. The DC to DC chargers I see are pretty expensive. I had the idea, why not just install a properly-sized solar controller, maybe about 30 amps, for the job. Is there something that I don't understand about this or will a solar controller work? Thanks for your advice.
You're thinking is backwards - invest in a DC > DC charger, the CTEK 250S Dual being one example, and take advantage of the fact it can also serve perfectly as a solar controller.
