PWM vs MPPT Test Results
Today (blue sky, not quite to STC at this date at this latitude 49.3N but almost according to the calculator on that) I was able to run a test on my 230w panel and Eco-Worthy 20a MPPT controller. ...

The "mainstream " MorningStar 15L ($300 here) gets 15a with a 230w panel but of course it cuts off amps at 15a. As reported by several forum members who have that combo.
You guys want a test with a 20a "mainstream" controller but don't expect more percentage gain than the ($102) Eco-Worthy got here, so what's the issue really? You guys are not being logical.
There is nothing wrong with the Eco-Worthy except you can get one for one third what a "mainstream" controller costs. Get over it. :)
X2!
yup, your results are plenty close enough to the tests I did back last fall in testing my Morningstar MPPT and then comparing to Morningstar PWM controller.
In bang for the buck, looks like you can't beat the Eco-worthy and like you point out, the Morningstar limits at 15A, about 5A less than I'd like.
And the Eco worthy vs. a Morningstar PWM, the win clearly goes to the Eco worthy, since both are about the same price.
