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...

Just to clarify, all voltages get doubled when in series, or when in series/parallel? Thanks!
The reason I ask, is there was a concern that two 12v panels in series would max out the eco-worthy, but if it's the Vmp that gets doubled in series, then that would not max out the controller. OTOH, doubling the Voc would.
In my case Vmp is 17.7v, and Voc is 22.4v, so 2x 17.7 is only 35.4, whereas 2x 22.4 is 44.8v (the controllers limit).
