About Cubenergy
Cubenergy is a manufacturer of battery energy storage systems (BESS) for utility-scale and commercial & industrial (C&I) applications. The company develops integrated AC/DC energy storage systems with in-house developments in battery systems, BMS (Super Parallel Active Charging, SPAC) and EMS. The product family comprises the AC block systems PowerCombo E5, FlexCombo D2 and FlexCube C1, which are based on a string BESS architecture with independently managed battery strings. Manufacturing and system integration take place at the headquarters in Shenzhen (China); for sales, commissioning and ongoing operation, the company maintains service and O&M centers in Europe and North America, including Düsseldorf, Munich, London, Milan, Lille, Uppsala and Houston. The company supports projects across the entire life cycle from delivery through commissioning to maintenance and optimization, supported by the cloud-based O&M platform WeWatt with servers in Europe and North America. Project references exist in over 40 countries, including grid services, renewable arbitrage and microgrid applications in mining.

Technologies & System Components
SPAC BMS (Super Parallel Active Charging)
Proprietary battery management technology with active cell balancing, fast calibration and battery balancing, developed in five iterations since 2016.
String BESS architecture
Each battery string is connected to its own modular PCS, enabling lower short-circuit currents, higher availability and easier maintenance.
WeWatt O&M platform
Cloud-based monitoring platform with 24/7 data acquisition, alarming and I%C3%A9C102/IEC104/MQTT interfaces on Amazon servers in the EU and North America.
