Quick Test of Eco-Worthy MPPT Controller
Ordered it on 3 Oct arrived at the door 23 Oct free shipping. Controller rated to 42V so watch that. EG I have it on one 230w panel, Voc 37v at 25C, so would be more Voc at cold temps. Not ab...

It is all about whether, at "normal" temps, the MPPT advantage over PWM is lost. Seems it could be, but my incomplete results are encouraging that it won't be entirely lost, leaving some sort of MPPT "gain" to justify the controller's higher cost.
I'll bet money the MPPT still outperforms the PWM as long as higher voltage panels are used...
Don't compare the MPPT to PWM with low voltage panels since it is not designed to have an advantage there...
