Germany's updated Renewable Energy Sources Act (EEG) raised the permitted inverter output for plug-in balcony solar systems (Balkonkraftwerk) from a 600 W to an 800 VA cap, alongside a 2,000 W (2 kW) module-power cap and simplified Marktstammdatenregister (MaStR) registration — there is no separate 'terrace' allowance. Registration via the Marktstammdatenregister remains required.
