Our AC-coupled battery energy storage system (BESS) in an air-conditioned 20' container offers exceptional flexibility and performance. With scalability that can be expanded as required, our system is suitable for a wide range of applications, including peak shaving, self-consumption optimization and flexibility marketing. Thanks to a modular architecture and a high round trip efficiency of 94.6 %, we guarantee a reliable and economical solution for your energy storage. Depending on the system configuration, the output varies between 337 kW and 405 kW with a usable energy content of up to 1,233 kWh.

Our 20-foot container storage solution is not only powerful, but also extremely safe. Equipped with a 4-stage safety concept, fire and gas detection system and an explosion protection mechanism, we offer comprehensive protection for your energy storage applications. In addition, we guarantee an exceptional life span: the battery comes with a performance guarantee of 10 years or 5,000 cycles with 75% residual capacity, which can optionally be extended to up to 15 years or 10,000 cycles with 80% residual capacity. Our systems comply with all relevant standards and directives, including VDE and IEC, and are suitable for operation at ambient temperatures from -20 to +40 °C.
