Cable size for 160W portable solar panel
Have 2 trailers. Trailer #1 has an existing 30A PWM charge controller being fed by a single 160W roof mounted panel. The controller is about 2' from the 2 6v batteries with a shunt between them for th...

OP-
The secret of good solar PWM charging performance is conserving voltage. Once that is done, amps will take care of themselves. You need at least 16.5 volts at the controller for it to work and usually 14.8 volts at the batts. Your winter RV will probably need more solar watts and battery voltage due to low temps.
