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...

Too complicated. I already know if I use PWM on 230w worth of 12v panels in parallel I will get 14.5a as expected max amps. Fact, BTDT etc etc.
So all I want to see is more amps than that from my 24v 230w single panel and MPPT controller, or else I wasted my money. Simple!
To make it an even, fair fight, I compare what I am getting with MPPT when I know the panel is getting full Isc (as required for full PWM)in steady conditions of blue sky-- no clouds going by every minute screwing up the readings.
Don't care about battery SOC either, since I can just run some lights and fans and note the diff in amps on the Trimetric with and without solar..
Same jumper cable(s) out to the array but different array and different controller. Same battery bank but the connections are a little different as required
Ken's money is probably safe, since I already saw 14.99a (which is above 14.50) in my initial test when panel had less than rated Isc.
I have hopes of getting 16.5amps or so when panel is getting full Isc and temp is not so high that it kills the voltage the MPPT needs to feed itself.
