Sonnenbatterie makes solar power generation and storage systems for homes and businesses that can help reduce electricity bills by 75% and dramatically reduce reliance on the electricity grid. The company founders started experimenting with intelligent lithium technology in 2008 and set up Sonnenbatterie in 2010.

Venture capital firm eCapital invested in 2013 to support the rapid expansion of the firm. Its investment helped fund the company’s international expansion, as well as extensive R&D to enable Sonnenbatterie to maintain its technological lead in the market. Thanks to eCapital’s involvement, Sonnenbatterie is on track to reach more home owners with its technology, and to take a leading position in the supply of electricity storage systems to businesses globally.
