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...

Not sure what "operating space" means. When I am on solar, morning voltage is say 12.5 but very quickly gets to 13 after sunrise. The battery voltage is mostly in the 13s during the day. Once it gets into the 14s, it shoots up very quickly to the mid 14s set point
So really, 13v to 14v is the "operating space" that matters.
It did hurt, but I used watts despite the pain in the interests of science.
Yes, I ignored the controller loss for MPPT that would have put PWM ahead. That saves Ken from counter-claiming MPPT works better on every foggy Friday the 13th in November.
Also ignored was the assumption that if the 130w panel was at 46.5C, then so would be the 230w panel. NOCT for the 130 is 47.5 but NOCT for the 230 is 45 plus or minus 2. But that may have nothing to do with their relative actual temps under the same sun.
