Wire Gauge Required Question
For some reason I just can't understand the various wire gauge tables, and I have tried to, so I am hoping somebody will take pity and do all the work! :) One table that I can follow says that for...

Under normal operating conditions (not cold or battery voltage held low), mppt gain over pwm is in the range 5% to 10%. Other estimates are plain hype!

So, during the course of a full day of use, the A-Hr benefit is typically quite a bit higher for the MPPT controller vs. the PWM controller.
again, depends on your use case I agree with Ken. I went from 8.5A to 11+ and since I seldom get battery charge high enough to taper the current, I'll take my extra 3A x 8 hrs =24AH, lot more than 10%
However, not paying attention to wiring losses could easily get you to the point where the MPPT controller isn't giving you much improvement over PWM, or at least not the full benefit.
