I just did the same in Norway but without the battery and 12.5 kWp panels for about the same price. Solaredge inverter and some Italian 450W panels.
400V TN 3P grid with export where I am paid spot. Had to fill in a form online that got approved automatically. The energy company (separate from the grid company) automatically detected my export and started deducing the sales of solar from the bill.
The installer had to confirm the installation to the Enova government entity to release my €3k subsidy though.
What country?
From where did you source the equipment?

The Netherlands.
I just contacted a well-reviewed solar installer and they took care of everything.
