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...

Where it gets sticky is all this stuff about voltage levels. My morning voltage these days is usually 12.6ish and soon gets into the 13s. It has no value for me to know what the comparable amps would be at 12v. I would just like to know what diff it would make if I had MPPT instead of PWM in my "operating range" (say 12.6 to 14.6v)
If I can, I will try for a test of each kind (12 and 24) around 13 and another around 14.3ish.
Well that's a good test for your real world conditions under these I suspect that battery acceptance rate will start to have a major influence in the results
I will bet you a cold one that you see little to no difference between the two since the battery will become the limiting factor. And any difference you do see will certainly not be worth the cost in the difference in the controllers
