MPPT 100/20 showing a -5v at night.

New system which I am very happy with comprising or two mppt's. One of these show around a -5vdraw every night. I first noticed this on the dashboard and then checked the graphs on the solar PV yield for this mppt which shows -5v through the night although the mppt states "off".

Is this normal behaviour?24-hr-of-10020.jpg


Any advice would be most appreciated...
