Power Sources shows excess solar power as being used

The power sources graph seems to show my full solar production as energy being used, while a part of it is being injected towards the grid.
I expect this to be shown as a negative value on this graph or am I wrong?

The elektricity usage graph shows it correct though.
Did I configure my power entities incorrect?

I figure it out, seems I didn’t have a ‘Power exported to grid’ Power measurement defined on my Grid connection. With ‘two sensors’ I could do this.
