About SONNEN

sonnen, founded in 2010 in Wildpoldsried, Germany, was acquired by Shell in 2019, bringing significant financial backing to this pioneer of home battery storage. The company introduced one of the first fully integrated home battery systems and has maintained a premium positioning focused on quality and longevity. The sonnenBatterie eco series uses LFP chemistry with a 10,000-cycle warranty—significantly higher than most competitors—reflecting confidence in product durability. The systems include integrated inverters and energy management, with the sonnenCommunity platform enabling peer-to-peer energy sharing in select markets. In Australia since 2016, sonnen has positioned itself at the premium end of the market, appealing to buyers willing to invest more upfront for high cycle life and German engineering. The Shell acquisition provides financial stability and resources for continued R&D. sonnen suits homeowners prioritizing long-term value and build quality over initial cost.
