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...

i think it is in float, that is were the 13.92 instead of 14.4x/5x
and the near 13v at battery come into play,
because float voltage and lower amps
won't sustain a higher voltage at the battery (because there are loads)
just like i have a higher than avg bulk setting
i raised the float setting, i set the float high with all loads off,
then checked it with loads running, so it was not dropping to low during solar float
my batteries spend almost no time at zero load, actually never since there is always inverter idle, even when all other loads are off
well ok..some days when it, is not hot, and nothing is running except for the fridge cycling, they get some float time, because solar exceeds idle drain parasitic loads
