Full modularity in building blocks of 79 kWh, maximum power 1.6MW and maximum capacity 2.5MWh
Build for extraordinary safety, space-saving and minimum O&M cost
Ultra-low auxiliary power consumption during standby for battery system and inverter
Built in site controller manage the entire BESS and act as a energy management system (EMS) facilitating power dispatch, safe system operation, communication with all system peripherals, data acquisition, communication with cloud and system diagnostics
Choice of different operating modes for providing grid support services: frequency, voltage regulation, peak shaving, transmission upgrade deferral, power on demand, energy arbitrage, synthetic inertia, black start
Possibility of island operation (independence from the grid)
Other: selectable harmonic mitigation (up to 50th), load balancing, stepless reactive power compensation, dynamic active and reactive power control (possibility of individual power control of each individual phase)
Technical properties of single battery rack
State of the art battery management system (BMS) assuring over/under voltage and over/under temperature monitoring for each individual battery cell
Redundant battery cut-off relays controlled by BMS
Temperature sensor for each battery module
Active current and control depending on battery cells temperature and state of charge (SoC)
Closed metal housing designed to assure no fire propagation between battery modules in case of battery thermal runaway
External mechanical emergency stop button
System diagnostics, error handling and automatic storage system grid connection/disconnection controlled by site controller
