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...

Between the low temp and the high temp there was only a half a volt difference in IMP, and less than a amp in MPPT. In the real world it isn't enough to make or break a system. Either you have enough solar or you don't.
Is MPPT worth it? Hard to tell with the prices like they are. The cost comparison was close until I saw a 200w kit selling for $300 shipped. I can't build a 24v system for that, it's at least $400. The extra $100 would get you a extra 30w if it was needed.
In a case where you had two 100w panels the money would be better spent on a third panel rather than a Eco-worthy controller. you would get more out of the investment.
Have a roof maxed out with panels and need a few extra amps, then a MPPT makes sense.
For a person setting up a mounted system, find the panels that fit the best and then figure out what controller to use.
