Is this required even for PV systems under 7 kWp ? I could only find new regulations from March 2025 for PV systems over 7 kWp.

I guess „it‘s complicated“. For our system, 6kWp with iMSys, the grid operator can cap the ingestion as they see fit. For systems over 7kWp, you are required to install a iMSys that allows them to cap. Systems without a iMSys must have the capability to cap to 60% (either at all times or „intelligently“ depending on your consumption). BUT if you install anything today, you most likely will install a iMSys anyway. Also export fees for 7kWp and below are a bit of a joke anyway.
