i dont have a boat or rv and i ve tried a controller that charges 2 battery with no success. so, im thinking the victron PWM duo would be the same since its meant to be for boats/rvs.
my problem atm is the power runs short by a couple of hrs to my requirements. the easiest solution is to buy bigger batteries but i have these FREE BATTERIES. i also have no problem on the panel/charging side.
my question is possible/safe to install these manual selectors remembering to isolate panels before any switch?
thanks for any input...
