Interest in mismatched panel test?
Ever since I got my first set of mismatched panels, seeing then react to different conditions convinced me they would interfere with a MPPT controllers ability to track. With the TS-MPPT-60 I could lo...

With the three 250w polys the controller has no issues adapting to changing light. It did eventually adjust in the first 4 panels series test but I had gone to change the leads around so I didn't see it until I was studying the graphs last night.
Today I started out with a series test on the 230w poly and 220w mono.
This is a full chart with the watts
This without the watts for a better look at the numbers.
For a basis I ran the panels separately to see what they did on their own. First the 220w mono, then the 230w poly.

Then I did a parallel test. No branch connector, I simple crammed both sets of leads into the controller terminals. It's not perfect as one set of leads is longer than the other but you get the idea.
After that I brought out one of the 250w and did a parallel test with first the 230w and then the 220w. Then I finish it with all three in series.
These were all in bright sun. I'm hoping for some over cast so that I can record the effect of the mono taking a dive on the rest of the array.
