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...

apparently, with the C40, you can regulate battery voltage to hold at your chosen set points (it still does the three-stages) using the "diversion" method even with solar as your "source"
In that case you would pick that mode, set your set points as usual, but now voltage is regulated by the "shunt" method where any excess voltage is diverted to real or dummy loads (if you have the dummy loads)
so in that case you would not have "series regulated PWM" to control the solar array source on the batteries, but the shunt method where the source Is not switched on and off.

Is it possible that Mr Wiz might have his controller in this diversion mode controlling his solar (if it has the dummy loads fitted), and that would explain how the input is higher than the output?
