What They Do
Sonnen GmbH is a leading company in the field of intelligent lithium iron phosphate (LiFePO4) home storage systems that are safe and sustainable. The products are designed to store excess energy from photovoltaic systems and promote energy independence for users. Key products include the modular sonnenBatterie, available in various sizes, as well as solutions like sonnenCommunity, which allows users to share renewable energy (source: sonnengroup.com). Sonnen has evolved from a battery manufacturer to an energy provider and operates one of the largest virtual power plants in the world, based on home storage systems.
Projects & Track Record
Notable projects by Sonnen include the sonnenCommunity, which connected over 50,000 households by 2020, enabling them to share renewable energy in a decentralized manner. By 2020, over 90,000 sonnenBatterien had been installed worldwide, allowing households to act as "small power plants" (source: sonnengroup.com). The production facilities in San Jose, California, and Atlanta, Georgia, support the U.S. markets and research and development. Sonnen has also partnered with companies like ES Solar and Haas Home Technologies to offer integrated solar battery solutions.
Recent Developments
In the past two years, there have been no major announcements or acquisitions; however, the acquisition by Shell in 2019 was confirmed in July 2023 (source: kfw.de). Sonnen continues to have over 90,000 installations and offers a standard 10-year warranty on its products. The ten-year anniversary celebration in 2020 highlighted the company's achievements, including connecting over 50,000 households and reaching a workforce of 700.
Working There
Sonnen offers a variety of roles in engineering, manufacturing, sales, and energy supply. The workforce has grown from 200 to over 700, indicating increasing demand in technical and expansion-oriented departments (source: wikipedia.org). The company culture fosters innovation and a decentralized team that operates in the rural environment of Bavaria while also acting globally. The headquarters is located in Wildpoldsried, where the core production of 1,000 units per month takes place.
