You just gave some very important information that solves the main mystery. In Vidoe 1 you are turning off the inverter load while voltage is at 14.4V. Battery voltage then surges to 14.8V. The inverter then shuts off.
Looks to me the inverter is fine. It does what it's supposed to do. The charge controller on the other hand does not maintain regulation at 14.4V. It looses regulation and allows battery voltage to rise to 14.8V.

I think you are under the impression that the voltage rise/spike is occurring at random. It is not, it occurs only when I remove a load from the inverter and I think this fits your definition of a "spike." The case of the video clips, I am unplugging my laptop AC charging cord while I'm using to power the laptop.
