Thanks! Ok so the MPPT is "not functional" but the "controller" still picks panel voltages as demand requires.
The MorningStar one has the MPPT "on" all the time playing with voltages to do this.
Is this just wording? As in--- the MPPT is "on" in Abs and Float but its "Tracking" is "not functional" and it is using its voltage fiddling circuitry it can do while tracking to find Vmp to get MPP for a different task now--ie keep the power "enough" to meet demand?
Somewhere off to the side is that if battery voltage drops to some set-point like 13.2, the MPPT tracking part comes back on and the controller is now in Bulk (even if the battery is not in Bulk I guess)
Not sure if that is the same thing as saying the controller goes back into Bulk if the power demand goes up to a certain amount at the output end of the buck converter. ("Power" is such a wishy-washy thing! :( )
