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...

I too got in another quick test using the 12v 130w panel and Eco-Worthy. Objective was to:
--compare panel Isc with the amps showing on the Eco-Worthy display and
-- compare the Eco-W's amps with the Trimetric amps as a check on the accuracy of the Eco W's read-out.
The amps display checked out (as did the voltage display on the earlier test)
Panel Isc (or better with MPPT) should have been showing on the Trimetric and also on the Eco-W display. The amps showing was higher than the panel Isc when panel disconnected. (Proving that MPPT was happening as advertised)
This last was important because with a 24v panel there is no simple way to compare what you should be getting with what you are getting. This test with the 12v panel showed that there is some higher amps effect for sure.
Another thing was the watts read out on the Eco W. No idea where they get the numbers from. Was getting some cloud effect (panel rated 8.2a Isc) and saw over 10a on the amps display and also on the Trimetric. Watts (it is a 130w panel) showed as many as 134w Other times when cloud reduced amps to 4.5ish watts were way down (didn't note number)
Anyway, I am not sure what to make of the watts display wrt the amps and battery voltage (or panel voltage if that can be derived from the watts and amps?) Anyway I don't really care about watts. :)
So that's it till April on that from me. The thing does work, it is real MPPT not fake, and it is up to the individual whether it would work in his set-up. I like it! :)
Thanks again, Jim.
