PWM input voltage, Xantrex C40 test video
here is the Video link, the fluke is plugged directly into the Solar panel drop wiring before it enters the controller right above the panel input protection fuse, that i use for a disconnect just c...

The video shows as load increases the fluke reading decreases, it also shows as sun increases, the fluke reading increases.
As load increases the duty cycle increases (less time at Voc, more time at Vbatt+), there is available panel power not being used
As sun increases, the panel has even more available power not needed so the duty cycle decreases (more time at Voc, less time a Vbatt+)
Fluke Voc only when NO load.
