About Us

Germany’s sonnen is Europe’s largest supplier of energy storage systems, and recently established a base in Australia which it sees as potentially its biggest market. The company was founded by Christoph Ostermann and Torsten Stiefenhofer in 2010 in the tiny Bavarian village of Wildpoldsried, renowned in Germany for its extensive use of renewable energy that produces five times more energy from solar, hydro and biomass than it consumes. In the remarkably short time since then, sonnen is into the eighth generation of its eco storage battery, a market leader in terms of reliability, and its long life (10,000 cycles). After taking battery storage market leadership in Europe in its main markets of Germany, Italy and the UK, sonnen has built a manufacturing and sales business in the US in 2015, and has struck alliances with partners, SunEdison, Zen Energy and True Value Solar in Australia, and BDT in New Zealand. In June 2016 sonnen was chosen by the Massachusetts Institute of Technology among the world’s 50 smartest companies, just 2 places behind software giant Microsoft. sonnen’s technology, is based on a Lithium-Iron-Phosphate (LifePO4) battery, it is capable of supplying above 75 per cent of a household’s energy needs, saving hundreds of dollars a year. Amazingly too, it will also allow the energy utilities to draw down power from batteries connected to households to meet peak energy demands. It’s been described as “a utility without power plants”. Sonnen markets a complete “Plug and Play system” including an in-built inverter for an AC coupled system retro-fit, as well as DC for new installations. The system is flexible, allowing the household to choose between battery capacities ranging from 2 kilowatt hours (kWh) up to 16 kWh, in 2kWh increments. A self-learning algorithm and data from the weather bureau processed by the smart system can identify the best time to start charging and, even with no-one at home, can activate appliances like washing machines to maximize sel-consumption. sonnen received a major boost in June when the venture arm of GE, the world’s biggest technology, energy, oil and gas, and water treatment company, joined the founding investors to inject tens of millions of dollars into the company to assist with its research and marketing efforts.
