Multiplus 12/800/35 Sustain shore current draw

I recently added a Multiplus 12/800/35 to my little boat setup, but it seems my configuration is a bit off....

While in sustain mode the multiplus keeps drawing power from the shore connection. The voltage of the battery (13.53v) is above the set sustain level of the Multiplus (13v). And during the day, the MPPT is delivering power too.

But the shore connection is also drawing power. Ideally, this should not be happening.

What do I need to do to correct this?


Best regards,
Pierre

Sustain Mode prioritizes solar (and wind) to charge the battery and power DC loads whilst keeping AC loads on shore power - your screenshot shows 1W of AC draw and therefore 1W is drawn from the shore.
