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...

Keep it simple to test the theory. My suggestion and assumes starting with a battery bank discharged to approximately 60% SOC so that amps aren't limited by absortion any more than necessary
Start with PWM and put a load on the battery approximately equal to the expected solar amps (so that Solar is putting out maximum available between load and charging). Take your data for 30 minutes or so
Turn off load and turn off/disconnect solar.
Swap controllers onto same battery bank and same panels. Turn load back on. Now take same measures as before. In theory if the MPPT is good one you should see maybe 10-15% increase in amps supplied by solar to battery.
