Now it works the way I envisioned it: I come back with the car at the end of the day and the car is charged from the house batteries which accumulated the solar energy during the day. 👍

What is the capacity of your house batteries?
In my experience, the issue is house batteries capacity being way lower than the car battery capacity.

@goodmirek 17.4kWh which is roughly 1/3 of the car battery capacity (55kWh), but you don't have to charge the car fully every day. 10% of the house battery is a reserve, I leave 20% for the house, so around 12kWh is available for the car which adds 80km to the car range.
