i like the 'rocker switch' voltage selection for battery top off 'absorption'
the thing is he is limiting the charge output
15 amp controller, 14.4 amps xx volts less than 200w from a 360watt power supply
he needs a bigger size controller
I can explain it to you.
But I Can Not understand it for you !
