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...

Just part of an amp mostly on the low amps I was getting. I didn't write down any numbers, just a couple of spot checks back and forth between Isc and the amps on the Eco-W (which I had confirmed were same as Trimetric) and the solar was a touch higher. Be about the same as Salvo got with his 130w if I did a full test on a proper sunny day.
With amps that low between 4 and 8 say, who cares if you get 5 or 9 instead? It's the old, "Percentage of what?" again. You can double your amps. From 1 to 2. So you get one more amp. Party time! :)
OTOH with a higher expected amps with PWM, you get more actual amps as the gain with MPPT. Still might not change your life having a couple more amps, but now you can get the advantages wrt wiring, fewer (but bigger) panels, series vs parallel if series happens to be an advantage in your case, etc.
For me it is about having one panel for the portable contraption instead of two (which I found awkward) and not much else. (Except the entertainment of playing with the MPPT and finding out how that works compared with what I am used to.)
