Zero Feed-in Control for PV Systems – Blueprint for Hoymiles + OpenDTU

Blueprints Exchange

Hi,

I’ve made a blueprint to implement zero feed-in (zero injection) control for photovoltaic systems with 1, 2 or more inverters (must be identical).

I’m currently using it with Hoymiles micro-inverters and OpenDTU. It should work with other inverters if it provides the same kind of entities.

My goal was to dynamically limit PV production based on real-time grid import/export to avoid feeding excess energy into the grid (especially useful in regions with legal or contractual injection limits).

Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.
