When lithium-battery storage systems for commercial and industry, then TESVOLT


TESVOLT specializes in battery storage for commercial enterprises. We produce electricity storage with the most modern battery cells: prismatic lithium cells from Samsung SDI based on nickel-manganese-cobalt-oxide. The intelligent cell control is certified by TÜV Rheinland. TESVOLT storage systems operate with low voltage as well as high voltage and can be connected to all energy producers: sun, wind, water and cogeneration - on-grid as well as off-grid.

The TESVOLT industrial storage solutions are manufactured in the first Gigafactory for battery storage systems in Europe at Lutherstadt Wittenberg in Germany.

Our awards

German Entrepreneur Award

The panel of judges appraised Tesvolt’s storage systems as a worldwide unique product. “What makes our storage systems so exceptional is the battery management system,” says Simon Schandert, co-founder of Tesvolt. It makes Tesvolt storage systems especially durable and economical. “While other storage systems on the market fall short when it comes to cost efficiency, Tesvolt’s products pay for themselves within a few years – even without subsidies.”

The smarter E Award

The smarter E Award" focuses on solutions and concepts that intelligently combine all energy sectors from the electricity, heat and transport sectors with renewable energies, decentralisation and digitisation. Tesvolt and Unlimited Energy received the award in 2018 for their "Offgrid avocado farm" project in Australia.
