What is balcony power plant registration and why is it mandatory?
Registration regulates the legal feeding of electricity into the grid and is mandatory for systems over 800 Wp in the MaStR and with the grid operator to avoid penalties. Benefits include promoting the energy transition, 0% VAT until 2026, and compatibility with dynamic tariffs via SunEnergyXT BK215 PLUS from DRBO Greenenergy.
How do I register my balcony power plant in the MaStR?
Create an account on www.marktstammdatenregister.de, enter system data such as power, location, and serial number, and receive the registration number.
