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...

Confusion of the issues
#1 the diode has nothing to do with the Xantrex on the house system
The diode was the original install on the chassis / starting battery trickle maintenance charge solar
#2 yesterday was cloudy before the rain started
It was impossible to have a steady reading, also anything going on off inside the RV ..water pump, light, fridge etc would create
Fluctuations in the reading...remember we are full timers
I know exactly what PWM is and can do, that how large machine tool spindle motors are controlled, I working with this tech 35 years ago
And my meter is a Fluke 77, slightly aged but works great
And I have a portable oscilloscope buried someplace
It matters NOT...That the output is PWM..
If the input has variations because of this..why is it that everybody else sees battery level at input and I see panel voltage at input
I say...Because of the difference in controllers
