Risen eFlex 418 kW / 836 kWh Energy Storage System
A liquid-cooled 836 kWh storage unit for large buildings and campuses, 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
98.4 kWh per square metre of footprint 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.
