H3-10.0 not exporting to grid

Hi everyone,
I am currently troubleshooting what is happening with my setup...I have an H3-10.0-inverter and everything works nicely except that it won't export to the grid. Charging the battery, house load, ec. works fine.
As an example today: very sunny, minimal house load and as soon as the batter was fully charged the PV power went to 0% as per the web app and nothing was exported to the grid.
There is no power limit set and the work mode is set to self-use.
Does anyone have an idea what else to look for?

Thanks
Daniel

Do you have an export setting set to 0? that would disable export

I found the following in the settings:
On grid > export control > 000000W

Update: I did have a talk with the FOX ESS Support - it seems the cabling between inverter and smart meter is the problem. Let's see what the electrician has to say...
