Panel to Solar Controller Wire Size
As some of you already know, I'm piecing together a solar system. Controller is a Morningstar 45A PWM. Panels will be two 12V 150W wired in parallel. I'm going to be using a combiner box on the roof, ...

Yes, a 3% reduction in cable voltage drop is equivalent to increasing the battery tapering voltage by that amount.
If you're seeing tapering around 13.5V, then a 3% better cable will increase the point where tapering begins to 13.9V. That's fairly significant!
It doesn't matter if you're talking about a converter or a charge controller, tapering means a loss in voltage headroom.

Are you saying I can affect the tapering point by changing the wire gauges? How does wire gauge relate to the panel's IV curves?
