🇩🇪 Germany allows plug-and-play home storage – since April 17, 2025
On April 17, 2025, the Federal Ministry for Economic Affairs and Climate Protection (BMWK) announced the groundbreaking decision: Plug-and-play battery storage systems for domestic use are now officially permitted in Germany. These systems can simply be plugged into a household socket, similar to balcony solar systems, provided they comply with the established limits of 800 W feed-in power and 2 kW PV power . No additional approval or specialist installation is required for certified devices.
“Battery storage is the fastest, cheapest, and most effective tool for integrating solar energy into the electricity market” – German Solar Industry Association (BSW-Solar)
📈 Strong growth: Monthly installations of home storage systems in Germany
The approval comes against the backdrop of an already rapidly growing market for battery storage:
-
2023: Approximately 570,000 new home storage systems were installed – an average of 47,000 units per month , doubling the total to almost 1.2 million.
-
2024: With an estimated 600,000 additional installations, capacity was increased again by around 50% – about 50,000 devices per month .
-
Beginning of 2025: The number of installed home energy storage systems now exceeds 1.8 million – and the trend continues to rise.
More and more households are combining their solar systems with storage. According to the Federal Network Agency (BNetzA) , approximately every second new PV system is already delivered with battery storage .
🔋 Practical example: Sunpura S2400 – the plug-and-play storage for your home
The Sunpura S2400 is a current example of a fully compliant, plug-in ESS system that is precisely tailored to the new requirements. The device combines:
-
2.4 kWh storage + integrated inverter
-
Simple plug-and-play installation without specialist personnel
-
Certified according to VDE-AR-N 4105 , EN 50549 and others.
-
Zero-feed-in function for grid-sensitive regions
-
Intelligent control via app for the use of dynamic electricity tariffs
With a maximum feed-in of 800 W, the S2400 precisely meets the technical limits for plug-in solutions and simultaneously offers emergency power functionality with up to 2,400 W output power in off-grid operation.
🏡 Conclusion: Citizen energy transition via socket
With the approval of plug-and-play energy storage systems, Germany has taken a decisive step toward bringing the energy transition closer to people's everyday lives . Combined with the continued market growth, it's clear that home storage systems will become as commonplace in German households as rooftop solar panels.
Products like the Sunpura S2400 demonstrate that technology and regulation now go hand in hand – for more self-consumption, lower energy costs, and a more stable grid.
