Risen eFlex 418 kW Energy Storage Cabinet
A liquid-cooled cabinet (enclosure) for battery modules for large buildings and campuses: power up to 418 kW, capacity configurable depending on the modules installed, up to 836 kWh. Battery modules are purchased separately and the configuration is chosen per project. Scalable by connecting 6–8 units in parallel.
Product code: SPC-ESS-RIS-SU836E418KM
Use case
A resort with conference facilities and a large car park needs to manage high peaks from kitchens, HVAC and EV charging.
A single eFlex unit shifts energy from cheaper hours to the peaks, and further units can be added as the site grows.
How it works
High energy density
Up to 98.4 kWh per square metre of footprint (fully populated with modules) and system efficiency above 94%.
Scalable
6–8 units can operate in parallel as the site’s needs grow.
Safety by design
Dry pipe, gas detection with ventilation, aerosol fire suppression and an alarm system; seismic design to Zone 4.
