CM2 is a highly integrated all-in-one hybrid system for commercial and industrial energy storage. A single cabinet combines battery modules, a power conversion system (PCS), BMS, EMS, thermal management, fire protection, power distribution and monitoring. The integrated smart EMS supports a range of operating strategies, from maximising self-consumption and tariff-based optimisation to participation in virtual power plants (VPPs). The system is included on the ELES list of approved equipment, simplifying connection to the Slovenian electricity distribution grid.
