Wittenberg/Germany, 13 May 2025 – TESVOLT, a leading European full-service provider of innovative energy storage system solutions for commerce and industry, 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.
Produced in Germany
“Although the new storage system is produced in Germany, the pricing is in the same ballpark as comparable Chinese storage systems. We can do this because our new gigafactory in Wittenberg enables high-volume production with the sophisticated manufacturing processes we have developed,” explains Simon Schandert, CTO and co-founder of TESVOLT AG. “One major advantage we have over Chinese storage system providers is that we offer on-site service and we also have all the spare parts on hand in our Wittenberg facility. We never leave our specialist partners hanging when problems arise.”
More funding for “Made in Europe”
In Austria, projects with battery storage systems manufactured in Europe will receive up to 20% more funding starting 23 June. This is intended to boost Europe as an industrial hub. “We expect other European countries to follow suit,” added Schandert.
Protection against cyberattacks
“These days it is particularly important that battery storage systems are safe from cyber attacks. Batteries are considered critical infrastructure, but unfortunately, the risk of battery systems simply being switched off remotely or third parties gaining access to sensitive data is very real in the current political situation,” says Daniel Hannemann, CEO and Co-founder of TESVOLT. “That’s why we use Infineon chips, which offer the highest security against cyber attacks on the market.”
Fully modular for smaller commercial operations and residential construction
Each battery module has a storage capacity of 6.25 kWh. The TESVOLT TAYTAN starts at three modules, which equates to a total capacity of 18.75 kWh. A maximum of 10 modules can be stacked on top of each other, which means the new storage system can reach a total capacity of 62.5 kWh. Up to four battery storage systems can be operated in parallel via an inverter.
Passive cooling
A further advantage is that the new battery storage system doesn’t require an active cooling system. The battery modules release their heat to the metal casing, so they are cooled by the ambient temperature. The TESVOLT TAYTAN can also be operated without an active heating system. The storage system can be operated at ambient temperatures of -20 to 50 degrees and is suitable for outdoor use.
The TESVOLT TAYTAN has an exceptionally robust design, and its metal casing meets the requirements of IP55, a high degree of protection. The LFP cells are particularly safe and the intelligent battery management system ensures high performance and safety. The storage system works with selected AC-based inverters and hybrid inverters from a range of manufacturers. Production is scheduled to start later this year. In the medium term, the battery storage system can then be used for lucrative energy trading.
