A story of success
“Our goal is to bring affordable, clean energy to every corner of the world. Even to places where people have no access to the utility grid.”With this vision in mind, Daniel Hannemann and Simon Schandert founded TESVOLT in the summer of 2014. Their goal is to develop and manufacture battery systems that store electricity from renewable energy sources as efficiently as possible. Since trade and industry have the highest energy requirements in many countries, the start-up concentrated from the outset on high-capacity storage facilities.

Outstanding battery management
The founders worked on their own battery control technology to make their products as durable and economical as possible. With success: TESVOLT’s award-winning battery management system ensures that commercial and industrial storage systems pay for themselves within just a few years.

But the success of TESVOLT comes not just from its superior technology, but also its agile company structure. In extremely dynamic markets, flexibility, speed and innovation are key. Conventional hierarchical organisations are finding it increasingly difficult to meet market needs. At TESVOLT, self-organisation and team culture are the order of the day, allowing the company to serve the markets of tomorrow with confidence.

Even today, TESVOLT is producing its commercial storage solutions in series in Europe’s first Gigafactory for battery storage, delivering them all over the world.


Up to now, TESVOLT has focused on developing and manufacturing battery storage systems for commercial enterprises. The energy storage systems we produce are based on lithium-ion technology, work with low and high voltages and can be connected to all energy sources: sun, wind, water, biogas and combined heat and power sources, whether on-grid or off-grid. All TESVOLT storage systems are produced in the first production facility in Europe with an annual production capacity of up to one gigawatt hour.

TESVOLT is now an “Aktiengesellschaft”
With the company’s transformation into an “Aktiengesellschaft” (AG) – a company form under German law comparable to a public limited company – we have positioned ourselves strongly to take on future challenges. As part of the transformation, the existing board members will be appointed to the Management Board. As CEO, TESVOLT co-founder Daniel Hannemann will take up the role of Chair. Co-founder Simon Schandert will be responsible for the products and their technical development in his role as CTO. Since May 2022, finance expert Philipp Koecke has assumed responsibility for his area in his role as CFO. Koecke has a great deal of industry experience in the area of renewable energy. He led the finance department at Solarworld AG for 15 years, until in 2017 he moved into senior management at a fast-growing technology firm.

Oliver Borrmann was appointed Chair of the Supervisory Board in the inaugural meeting, and Claudia Thonet Deputy Chair. Johannes Meran and Ralf Christian are also members.

“Our mission is to provide
affordable energy anytime
and anywhere.“



Our battery storage systems have been specially developed for the complex requirements of industry and commerce. Safety, reliability and economic efficiency take priority here, along with a first-class installation service.

For manufacturing our battery storage systems we rely on high-quality components – such as prismatic high-performance cells from Samsung SDI – and smart battery control systems.
Depending on the application, with our E series or A series we offer concentrated power in the smallest of spaces.

Maximum Safety

Prismatic battery cells are very durable, safe and powerful, especially when compared to cylindric cells.

Maximum Lifespan

All components are built for a 30-year lifespan or 8,000 cycles.

Uncompromisingly Powerful

The continuous power is 1C – and even 4C for short periods – enabling professional use in trade, agriculture and industry.

Future-Proof Flexibility

Our TESVOLT storage systems not only offer flexible configuration options at the time of purchase, but thanks to the innovative Active Battery Optimizer technology, their capacity can also be expanded years later.
