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...

Sure, once it gasses at 16V, it's probably zero percent. However in absorption, AH will be close to 100%, while WH is much lower. The surface charge voltage, battery and cable resistance all eat up watts, resulting in WH errors.
Barre says "gassing voltage" starts around 14.2v. Your curves on voltage where it take a jump are related to that AFAIK.
There are AH errors too, so I don't agree (at this stage anyway.) Check out the blurb in the Trimetic manual eg.

Page 10 of 16. Ref to "charge efficiency" factor P10. Also para 6.2 and 6.22 part 4
