Even though I operate the wall box in green mode, it occasionally draws power from the grid

Only a few amont, but still some ~ 3 kWh power from grid - even sun is (mostly shining).

How can I avoid any power from green in green mode charging on my wallbox?

Assuming this is an EVCP for your vehicle?

If yes, maybe there is a minimum output needed for the car charging in green mode. If correct, then the grid would need to sometimes fill gaps if solar output dropped momentarily.

I could be wrong of course, just an educated guess.
