Made in Germany: Lithium Battery Storage Systems
For Industry, Commerce and Agriculture

Safety, reliability and efficiency – without compromise. That’s what you can depend on at all times from our innovative and sustainable energy storage systems. Our systems prove their performance capacity every day in more than 6,000 projects across the globe. We are driving forward the energy transition together, protecting the environment and your budget.

From 10 kWh to 30 MWh outputs, connected to low or high voltage, on-grid or off-grid, in combination with solar, wind, hydro or combined heat and power sources – our broad product portfolio covers the full range of applications and can be individually adapted to your requirements. State-of-the-art prismatic lithium battery cells from Samsung SDI combined with our patented and TÜV-certified Active Battery Optimizer smart cell control system form the core of our storage systems.

Latest press releases

Long wait to connect large storage systems to the grid, unlike smaller systems
Distribution grid operators are receiving a large number of requests to connect large-scale energy storage systems to the medium- and high-voltage grid. This has been published by Bayernwerk Netz, Bavaria’s largest distribution system operator, and Mitnetz Strom. Due to the necessary grid expansion measures, the waiting period for applicants is usually at least five years. Start-up TESVOLT ENERGY has found a solution that can quickly connect battery storage solutions to the utility grid. It gives commerce and industry – which usually already have a sufficiently large connection to the low-voltage grid – the previously lacking incentive to connect smaller energy storage systems of 100 kWh or more to the utility grid.

TESVOLT and Samsung to collaborate on cybersecure battery systems for public utilities
TESVOLT, a leading European full-service provider of innovative energy storage solutions for public utilities and commerce, is collaborating with Samsung SDI to provide public utilities with a particularly secure, state-of-the-art battery container and comprehensive project management on site. Data servers in Germany and KRITIS-capable software are designed to effectively protect the new battery storage solution against cyber attacks. In addition, a world-first thermal runaway propagation prevention system ensures it’s a safe investment. The new SBB 1.5 battery container with 5.26 MWh storage capacity will be compatible with various European inverters and will be launched with exceptional performance and guarantee features. With the new storage solution, public utilities can also reliably provide grid services and participate in energy trading.

TESVOLT presents new stackable domestic and commercial storage system
TESVOLT presented its new battery storage solution TESVOLT TAYTAN at the ees Europe trade fair in Munich. The system consists of battery modules that simply plug into each other – with no external cables. Between three and ten modules can be stacked, depending on the desired storage capacity. The battery modules for the new energy storage system are manufactured by TESVOLT itself in its new gigafactory in Wittenberg. This means that in future, project planners who use the TESVOLT TAYTAN can apply for the “Made in Europe” funding bonus. The battery system is designed to work with different inverters, while built-in Infineon chips protect it against cyber attack. A 12-year performance guarantee ensures investment security.
