FROM A SINGLE SOURCE: CYBERSECURE BATTERY STORAGE PROJECTS
FOR COMMERCIAL USERS AND MUNICIPAL UTILITIES

Welcome to the battery age!

Battery storage systems are true all-rounders in the power grid and an indispensable part of the energy transition. They also enable high revenues from energy trading and significantly lower electricity costs.

Everything from one source

As a one-stop shop, TESVOLT delivers not only first-class battery storage systems for commercial customers and municipal utilities. We support you from the very beginning — both in storage projects for your commercial clients and as a project developer for municipal utilities that want to complement renewable power plants with battery storage or build their own battery parks.

We also offer electricity marketing on the energy exchange via TESVOLT ENERGY — with particularly high returns thanks to our so far unique trader benchmark model.

6,000 projects worldwide

More than 6,000 projects around the globe demonstrate their performance every day. Together, we are driving the energy transition forward and enabling the free and decentralized use of energy as well as profitable Energy Trading — already for systems starting at 50 kW.

These experiences are also bundled into our own battery management system and our trading software.

Digital or face-to-face

For our specialist partners, we provide all services fully digitally: around the clock, they can access everything online — from training via the TESVOLT Academy to project planning including bill of materials, quotation tools, online shop, app-based commissioning, and remote maintenance of systems.

At the same time, our support team is also reliably available by phone or on site.

Cybersecurity in focus

Protection against cyberattacks is more important than ever today.

That is why we rely on a comprehensive security architecture with our own communication hardware.

In addition, we use only inverters from European brand manufacturers.

Energy storage solutions for all requirements

Future-Proof Energy Projects
With us, battery storage, software, services, and energy trading are perfectly aligned with each other.

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.
