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 Mr Wiz! At least we now know the C40 is indeed a normal series PWM.
I didn't really know about that PWM duty cycle effect when the controller is controlling, so I learned about that. :)
As you know, you are really taking a beating on the controller to battery path, but it is a complex situation to do anything about in the MH.
Usually means you will undercharge the batts wrt the intended voltages you set, but you also do the weekly "cure" with the VEC1093. Mex says not to worry too much about the AGMs not getting quite the "right" voltages.
Battery voltage sense wire?
