Eco-Worthy MPPT and Solar30 PWM Test
Did a quick backyard test of my two solar controllers using the actual trailer wiring etc as intended for camping with solar later this month. Got some blue sky, no clouds. The Eco-W on the 230w p...

PT thanks, now I remember something about the frequency for staying at MPPT where it keeps re-finding it and while it is searching after losing MPPT the controller is not doing much or something like that, so you can have better ones than others.
I don't know if the time it spends searching and not actually doing much affects the amount of amps it does when on target. I suppose it could affect the AH haul if 'average amps' is less. I don't know if that is the same thing as rated "efficiency" either. Could be two different things. Way too complicated.
If anything like that, then you should be able to quantify how much better one MPPT controller is than another by running a timed AH haul contest. Then you could look at their prices to see if the winner is 'worth' the extra AH.
If one costs $102 like the Eco-W and the other costs $302 but gets 2 AH/day more for having faster MPPTing, then you could decide if you want to pay $100 per AH for those extra two AH :)
I have no idea where Eco-W fits on that scale, but I am happy that it is doing more than PWM by that 9a vs 8a amount I got. I doubt if I strapped one of those $600 MPPT controllers onto the panel instead, that it would get more than that 9 vs 8 I get now. No way to know unless somebody who has a $600 controller tries it and reports back.
