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...

i won't debate it any more, but wattHrs is more accurate
the meter i use shows me everything, amps, ampHrs, watt hrs, even the Lowest voltage the batteries got to overnight, when the fridge kicked on and the inverter surged
ampHrs at 11.5v is not the same power at 12.6v
wattHrs is absolute A*v, 120whrs ..1amp 120v for 1hr or 10a at 12v for 1 hr, or 1 amp at 12v for 10hrs
its all 120wHrs,
many people use ampHrs and many use 12.0v constant, but panels are rated in watts and different voltage and amps, and voltages much higher than use for 12v charging
when comparing many different items across a "system"
wattHrs eliminates much of the conversion needed , if everything is stated in wattHrs
