Advantages
- 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
- build 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.
- improving renewable energy self-consumption (storing during daytime for usage during the night)
- cloud access allowing for system monitoring, control and data acquisition
- ROI maximized by using advanced algorithms in the cloud considering consumption patterns as well as energy and weather forecast data.
- integration of external energy meters and other auxiliaries e.g. heat pumps and EV charging
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
