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...

Very true
Another point to consider is "time of day"
MPPT will give you more on the morning fringe
But this also means that the batteries SOC and voltage rise faster
So later in the day when the PWM showed xx amps..The MPPT shows yy amps, But Not because it's losing power, but because the batteries Need less power, voltage is up and they are accepting less power,
At the same time of day as previous PWM readings
There are many things to consider that most people don't think about
BTW
Took a look at some of the solar controller videos posted
One guy in particular is on a Grid Tie system
So the utility grid Is going to happily absorb everything that can possibly be generated, which has nothing to do with our situation of charging batteries,
Except to show the possible abilities or liabilities of a particular controller
