  • The sonnenBatterie

      • 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 75% 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.
      • How the sonnenBatterie gets you through the day.

        • 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.

      • Suitable for You

      • The right size energy storage for any need – any time.

        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 2 kWh to 16 kWh the sonnenBatterie will power a detached house, a multi-family house or an apartment block. The sonnenBatterie's energy capacity can be individually expanded in blocks of 2 kWh - should you ever feel the need to increase the power storage in your house.

      • More than a battery

      • Complete system.

        All included: high-end 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 on a minimum of space.
      • Long Life Non-Toxic Battery

      • 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 much higher longevity and 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.
      • Your Independence

      • 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 sonnenBatterien can be set up as a cascading cluster. Thereby increasing the capacity and power of the sonnenBatterie up to a maximum of 48 kWh. More than enough to satisfy the energy needs of your business.

      • The sonnenCommunity

      • What is the sonnenCommunity?

        The sonnenCommunity is a community of sonnenBatterie owners who are committed to a cleaner and fairer energy future. As a member you can share your self-produced energy with other members of the sonnenCommunity. Since you are exclusively using renewable energy, there is no need for a conventional energy provider anymore.
