Just witnessed MPPT voltage drop below 14V
Well this is interesting. Half sunny half cloudy day, 92 degrees out. Collected this data looking at the turnigy for the maximum panel output (not max amps to battery which was fun but not any real ob...

FOUND THIS article on an electronic load.
This circuit is useful for characterizing photovoltaic modules, which have two source modes.. . . . . At voltages below VMPP, the photovoltaic modules look like a current source. It is normally difficult to characterize this flat region of the curve with a simple current-mode electronic load, because the voltage output is sensitive to small variations in current, and thus a constant-voltage mode load is a better choice.
