PWM vs MPPT Test Results
Today (blue sky, not quite to STC at this date at this latitude 49.3N but almost according to the calculator on that) I was able to run a test on my 230w panel and Eco-Worthy 20a MPPT controller. ...

I did a test last month with the EcoW on the 12v 130w panel. I got 9a MPPT vs 8a PWM. There is no doubt that the MPPT gets slightly higher amps, similar to what Salvo got on his test.
It is true that you can change the results more in favour of MPPT by comparing them at low battery SOC. In real life, by the time the sun gets up high enough you are already climbing in batt v so may never see max amps even at high noon. Another "situational" thing, "depending"
You can't fine tune your solar. You will have too much or too little each day but at least you can calculate what your set up could do and then after that you can see if it is still working about right.
