Bucking and MPPT?
Question here is whether I saw where the effect of MPPT was seen or not---was the amount of change about right? Situation was controller (Eco-Worthy 20amper) was showing 14.4v (as set by me for Flo...

It was previously established in other threads that MPPT controllers have bucking and MPPT as separate functions. Many( most? all?) only do MPPT in Bulk. In Float they still buck to get the amps up to meet the demand.
In this case, where panel Isc is 8.3, there was 12.4 amps developed. That was from bucking. Then the controller went into Bulk so MPPT was engaged and amps jumped. That made the watts show higher too with the voltage the same.
I just wondered if that jump in amps was "about right" for MPPT "effect" from whatever power point it might have been on in Float without the MPPT engaged. Might be a way to tell if the controller is acting properly if the observed effect (if that was all MPPT effect) is about right.
