Intelligent, long-lasting and economical – the sonnenBatterie
The sonnenBatterie is a high-tech storage system that has proven itself in thousands of households – every day. The combination of a PV system and a sonnenBatterie will allow you to cover about 80% of your yearly energy requirement with self-produced and clean energy. Since your energy is being generated on your roof and not by some anonymous energy provider you are more independent than before. So take your energy future into your own hands and reduce your energy costs to a minimum. The decision for a sonnenBatterie is also a decision for the highest standards in safety and quality that "Made in Germany" stands for.
Clean energy for you or all – this is how it works
Discover the sonnenBatterie and the sonnenCommunity in this short Video.
Clean energy for all: presenting the sonnenBatterie and the sonnenCommunity.
Self-produced energy round the clock – discover how the sonnenBatterie works.
During the day the sonnenBatterie optimises the usage of your solar power in your house.
The sonnenBatterie is an intelligent control centre that manages all the solar power in your household.
The sonnenBatterie will reliably supply you with energy during the night time using the stored solar power generated during the day.
In the inter-connected sonnenCommunity all members share their energy with one other to reach a maximum degree of independence.
How the sonnenBatterie gets you through the day
Clean energy during the daytime, in the evening and at night.
Morning: minimal energy production, high energy needs.
At sunrise the solar panels start to produce energy, though not enough to cover the morning energy needs. The sonnenBatterie will bridge the gap with the stored energy from the previous day.
Midday: highest energy production, low energy needs.
In the daytime the energy generated from the solar panels is at its peak. But since nobody is home the energy consumption is very low so that most of the generated energy is stored in the sonnenBatterie.
Evening: low energy production, high energy needs.
The highest daily energy consumption is in the evening when the solar panels produce little or no energy. The sonnenBatterie will cover the energy need with the energy produced in the daytime.
Technology from the market leader for intelligent energy storage
The sonnenBatterie comes with the experience of 40,000 installed systems - build into each unit, the newest technology for highest independence and maximum longevity. All in a compact case that offers highest flexibility thanks to its modular design.

Everything included, ready to connect
single phase, three phase and hybrid
Meets your energy needs whether you are a small or a big family
Every household has its own very specific energy needs. That's why the sonnenBatterie was developed as a multi-stage storage system that can be adapted to the most diverse energy needs. With storage sizes ranging from 5 kWh to 15 kWh the sonnenBatterie will power a detached house or a multi-family house. The sonnenBatterie's energy capacity can be individually expanded in blocks of 2.5 kWh - should you ever feel the need to increase the power storage in your house.
High quality components perfectly tuned to your needs
The sonnenBatterie is a complete system - ready for connection. This means that inside of every sonnenBatterie you'll find not only the extremely durable battery modules but also an inverter, an intelligent energy manager, measurement technology and the software to operate it all smoothly. All in one handy box. In contrast to most other battery systems in the market, the sonnenBatterie components are build into a single high-quality casing and perfectly attuned to each other - thereby ensuring a very high longevity and maximum quality with a small footprint.
Batteries are the basis of all energy storage systems
Over time they will be charged and discharged many thousands of times. For that reason the sonnenBatterie is based on the most reliable and sustainable battery technology available and exclusively uses lithium iron phosphate batteries (LiFePO4). These batteries offer a greater longevity and higher safety than most other lithium-ion batteries that are commonly used in smartphones, laptops or electric cars. Did you know: lithium iron phosphate is the only battery component that occurs naturally and does not contain any toxic heavy metals.
More than the sum of the parts: independence for your business
Should you ever require more power - for example when you are running a business - multiple sonnenBatterie can be set up as a cascading cluster. Thereby increasing the capacity and power of the sonnenBatterie up to a maximum of 45 kWh.
