sonnen GmbH

Uncovering potential, seizing opportunities and developing sustainable energy solutions: For us, motivation and innovation are synonymous and rank first on the list. In 2010, our journey began in a small town in Southern Germany. Driven by the desire to create a clean and affordable energy future for everyone, our founders Christoph Ostermann and Torsten Stiefenhofer developed the first sonnenBatterie. At a time when solar energy was only fed into the grid, they created a system that allows households to store and consume their self-generated energy, day and night. Today, we are a global leader in energy storage solutions with offices in Germany, Italy, Great Britain, the United States, and Australia. We made it our purpose to challenge the existing energy system, so that our customers and partners worldwide can enjoy a clean, reliable and affordable energy future through the smart solutions that we offer.
