For a couple days been noticing higher than the 14.6 voltage,.....going to 15, and even 15.5,....I knew something was not right. The next day it was showing 16, then quickly went to 17+.......I quickl...

"But a buck converter has a setting for output voltage, so if you have that, why would you need any PWM to monkey with the panel input to the controller?"
hmmm, that's a good question. I guess I need to read up on how, exactly, pwm operates, in comparison to a basic buck converter. And it comes right back to your gizmo experiment.
The way I'm looking at this, I should have a back-up controller on hand, anyway, so why not go with a reasonably priced mppt like the eco-worthy? And as a bonus, I can compare the performance of the two.
And I was thinking I could even run both at the same time, one off each panel. But that would probably just confuse the controllers? Or, at least, make one the master and the other the slave?
