Test Method PWM vs MPPT ?
I might get a chance to compare MPPT with my PWM on the set of two 100w panels. I get 12.6 (Isc) now with PWM so that is the "standard" I was thinking of a quick connect set-up to swap controllers...

All I have to test with is two 100w panels although I do have the single 130w, which Salvo has already tested that amount.
Not long after the solar starts to work in the morning, battery voltage is 13.x. After that it gets to 14.5ish, holds that for two hours and drops to 13.7ish.
Fair test of MPPT would have to be between 13 and 14.5v the way I see it. If it gets higher amps then you should get more AH in the same time
I am told that factories do not produce all panels the same. What they do is ship a container full of panels where each panel is listed by serial number and each is up and down from nominal and the average in that container meets the spec.
It is luck of the draw what you end up with up or down from nominal from a dealer who got that container.
