ENERGY STORAGE SYSTEM
A future-ready investment for your home
Cover up to 80% of your energy needs with your own solar power
The sonnen battery is a reliable storage system for your solar installation. It allows you to use your solar energy exactly when you need it — at any time of day.
Instead of using only around 30% of the energy your system produces each year, a sonnen battery storage system can help you cover up to 80% of your household’s energy needs with the power generated on your own roof. It is a smarter and more cost-effective solution.
In the morning
At first light, your solar system starts producing electricity. But in the early hours, sunlight levels are not yet high enough to fully meet your household’s energy demand. That is when the battery steps in, supplying the energy stored the day before.
At midday
During the day, your solar system generates most of its electricity.
When production exceeds consumption, the battery stores the surplus power so it can be used later, exactly when it is needed.
In the evening
As the sun sets, energy demand typically rises while solar generation drops.
At that point, the battery provides the stored solar energy, allowing you to continue using clean electricity even after sunset.

LFP battery cells
Since the very beginning, we have relied on lithium iron phosphate (LFP) technology for our batteries. This chemistry is not only safer and more environmentally friendly, but also more durable than many other cell types. LFP batteries are known for their long service life and high efficiency — without relying on critical raw materials such as cobalt.
In-house battery research
At the sonnen laboratory, our experts continuously test advanced storage technologies for a more sustainable energy future. Strict testing procedures ensure maximum safety, efficiency and durability. Extreme stress tests simulate decades of use, while our storage systems are constantly refined for the smart energy grids of tomorrow.
Data servers in Germany
All data is stored on servers in Germany and protected according to the highest security standards. Daily system monitoring allows potential issues to be identified at an early stage, while automated battery maintenance helps ensure consistently reliable performance.
German engineering. Proven expertise.
With more than 150,000 batteries installed worldwide, sonnen stands for proven quality and continuous innovation. Since 2010, when we started in Wildpoldsried in the Allgäu region with a bold idea and strong engineering expertise, we have grown into one of the world’s leading providers of intelligent battery storage systems and smart energy services.
The night belongs to sonnen
It is simple: during the day, you use the power of the sun. At night, you use your smart solar battery. Our integrated system helps you maximise your savings year after year through truly intelligent energy management.
Smart self-consumption
By optimising your PV self-consumption, you can use your solar energy even more efficiently — with clear benefits for both your budget and the environment. A high level of self-consumption is one of the most cost-effective ways to meet your energy needs with clean power.
Proven quality
With more than 150,000 installed units around the world, sonnenBatterie has proven itself.
That's why we guarantee all components for 10 years or 10,000 charging cycles.
Smart control
With the sonnen app, you can monitor your home’s energy flows in real time. Track production and consumption, set your backup energy reserve, or choose the charging mode for your electric car — all from one app.

Smart solutions for your home
Monitor your energy in real time
With the sonnen App, you get precise, real-time insights into your energy use, increase your independence and actively contribute to the transition to clean energy.
Stay protected with backup power
With our backup power solutions, you will continue to have electricity available even during a blackout. Our systems switch on seamlessly and also offer fully autonomous, independent operation. That is energy independence at its best.
Industry-leading energy throughput
With 8,500 cycles per installed kilowatt-hour, sonnen batteries deliver up to twice as much usable energy as many conventional systems. Advanced LFP technology and our in-house battery management system ensure reliable performance, high efficiency and long-term value.
The benefits of a sonnen battery
- Increase self-consumption and reduce your reliance on the grid.
- Lower your energy costs, because the cheapest electricity is the electricity you generate yourself.
- Enjoy greater peace of mind with reliable protection during power outages.
- Make a long-term investment with a 10-year warranty and up to 10,000 charge cycles.
- Reduce your CO₂ emissions by using more of your own solar energy and relying less on external power sources.
