ANOTHER D*** Solar Question!!!!
Just upgraded trailer to a new, much larger trailer (Timber Ridge 280RKS) which has a "huge" 10W Zamp solar panel. The panel is wired directly to the battery through a master switch and 30A breaker. ...

I was not thinking of PWM on/off but just the "low frequency PWM" action. I don't know anything about the way high frequency PWM works for on/off.
I think of lower voltage as battery voltage on the IV curve when that would mean a higher I. To me, line loss would just make the controller think the battery voltage is higher than it is, so it would start controlling (reducing the amps to maintain the voltage) at its set Vabs when the battery was not that high in voltage yet. This could lead to undercharging the battery because there is only so much daylight left, and the battery might need the higher voltage to gas properly.
