TESVOLT will introduce its new 5 MWh Tallon storage container at E‑world in Essen this February, positioning it as a cyber‑secure solution for large‑scale battery parks and co‑location projects.
The system is built around TESVOLT’s own battery park control platform, designed to strengthen digital protection at a time when cyber‑risks to energy infrastructure are under growing scrutiny.
CTO and co‑founder Simon Schandert highlights the company’s approach: “Today, many battery containers hardly differ from one another… but then we do something differently from many others: we integrate our own battery park control system, which provides significantly higher protection against cyber attacks.” All internet connections run through dedicated VPN tunnels, with outbound links restricted to one‑way communication and hardware shielding the controller from direct access.
TESVOLT has also opted for European inverters, reflecting wider concerns about supply‑chain security. As Schandert notes, “We have long recognised the concrete risks posed by inverters from certain manufacturers.” Tallon supports units from SMA in Germany and Power Electronics in Spain.
For municipal utilities, TESVOLT is promoting a full one‑stop shop model. Sebastian Jänig explains, “We do not simply deliver a battery container… we provide battery containers tested by us with proprietary software, as well as project planning, installation, operation, monitoring and power trading.” Through TESVOLT Energy, the company also offers access to competitive trading via leading German partners.
The Tallon system’s modular design allows flexible DC outputs, scalable capacity and efficient power matching. High fire‑safety standards permit installation with just 10 cm spacing, and LFP modules support long service life. TESVOLT backs the system with a 15‑year warranty.
