Cheap China Solar Controller Failure
For a couple days been noticing higher than the 14.6 voltage,.....going to 15, and even 15.5,....I knew something was not right. The next day it was showing 16, then quickly went to 17+.......I quickl...

But only while there is a significant load, correct? (Otherwise, you would just see what the battery will accept at the time)
Correct. I use my panels as a power source in the day time. The only loads that could out draw the 30a+ that I could get from the twin 245's was the larger inverter loads. Turn everything on in the trailer at once and even the 230w could provide enough to keep the battery in float.
I'll be interested in the comparison between PWM and MPPT with the Eco-W. I'd do it but I don't have the 12v panels. At least I'll be able to compare what a respectable Chinese made controller with a American name plate will do against the Eco-W but I suspect the difference in output if any will not be worth the expense. The additional features on the other hand.....
