We at SAX successfully develop and produce battery storage systems.
Our storage systems were test winners in the 5 kWh and above class.

Industry professionals install our storage systems in buildings and facilities. They are important partners for us. As an energy storage system manufacturer, we place great value on exchanging ideas with these professionals.

For this purpose, we invited the electrical specialists from the Ulm / Neu-Ulm Electrical Guilds and the SWU Energy Community to visit SAX in Erbach on November 20, 2025. The interest exceeded all our expectations. Together with Guild Master Uwe Wöhrle, 42 specialists from the entire Ulm/Neu-Ulm region came to us.

One week later, we invited the energy consultants through the Ulm/Neu-Ulm Energy Agency. We were pleased to welcome 25 highly competent energy specialists and Roland Mäckle, the managing director of the Ulm Energy Agency.

Both groups of visitors were thoroughly informed about the unique technology of the SAX storage system. Numerous questions and comments on theory and practice underscored the visitors’ expertise.

During the tour of our production and testing areas, participants gained a comprehensive understanding of how theory is implemented in the construction of the storage system. They were very impressed by what is produced at SAX, the energy storage system manufacturer, in Erbach.

Thank you for your interest in the SAX storage system and for the intensive exchange of information and experience with our specialists. We are particularly pleased with the numerous positive feedback from the professionals.
