MPPT 100/20 Load switch low voltage level

I configured MPPT load output with low voltage level 22,0 V and high voltage 25,0 V as you can see in the screenshot.

Basically everything works really fine but I don't know why load output is disconnected at ~22,3 V every day:

Does anybody have an explanation for that? Jumper is removed and Raspberry Pi with Venus OS connected on VE.Direct Port.

Thanks for your support!

Maybe just a reading difference. Have you tried adjusting your cut off voltage 0.3v lower?

It seems that there is an offset of about 0,3V. I configured cut off voltage with 21,7 V now. MPPT disables load at 22,0 V now.

Can somebody explain this behavior?
