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...

Thanks for doing the fuse.
If your Bulk setting is 14.5 and the controller output is at 14.6, doesn't that mean it is finished Bulk and is now controlling with a PWM duty cycle??
It would be good to get the input voltage when the output voltage is still around 13v in the morning on a sunny day before the controller starts controlling.
I suppose with the higher than battery voltage at output, you need to allow something when setting Bulk and Float. Do you add a bit more for Bulk (high amps) and not much for Float (low amps)? I don't know what would work best, something to learn! I know you discussed before about the controller location and your choice about that, so what is the work-around for voltage settings?
