Use a solar controller as a DC to DC charger?
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 abo...

all solar controllers 'buck' the voltage that is reduce the input from somewhere above 15+ even 12v panels have an open circuit voltage 21+
no solar controller i have read the specs on will increase voltage on the output side
MPPT will take higher voltage and make more amps at battery charging voltage
but that is still less voltage than what is on the input side
you need DC to DC voltage BOOST, output volts higher than input volts
that doesnt come cheap
