Overview

  • More than one million plug-in mini-PV systems are now registered in Germany, underscoring mainstream adoption.
  • Policy guardrails remain central: combined module output must stay within 2,000 W, total inverter output per home is limited to 800 W, only one inverter per circuit is allowed, and registration runs via the Bundesnetzagentur’s Marketstammdatenregister.
  • Hands-on user tests report easy DIY setup and meaningful savings, including a Quattro set with Anker Solarbank 3 logging about 280 kWh in its first month and estimated monthly bill cuts of roughly €30–€60.
  • New modular storage options are broadening choices, with Solakon ONE launched on September 7 offering IP65 weather protection, LiFePO4 cells, app control and expandable capacity, alongside reader praise for design and straightforward installation.
  • Installers caution on structural and electrical safety, urging robust mounts, CE-marked components and compliance with DIN/VDE standards, while the final 800 W norm text and definitive socket-connection rules remain unresolved.
