Our Story

"Our goal is to bring affordable, clean energy to every corner of the world. Even to places where people have no access to the power grid."

With this vision in mind, DanielHannemann 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.

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.

Today, TESVOLT produces its commercial storage solutions in series in the first Gigafactory for battery storage in Europe and delivers it all over the world.

TESVOLT specializes in battery storage for commercial enterprises. We produce lithium-ion-based power storage units that operate at both low and high voltages and can be connected to all power generators: Sun, wind, water, biogas and combined heat and power - On-Grid as well as Off-Grid. All of TESVOLT storage systems are produced in our own production facility in Germany. The intelligent cell control is certified by TÜV Rheinland.

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

Our Products

Maximum Security

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

Maximum durability

All components are built for 30 years lifetime or 8,000 cycles

Uncompromisingly powerful

The continuous power is 1 C - for a short time even 4 C - and thus allows a professional use in trade, agriculture, and industry.

Also flexible in the future

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