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.
How we work with you
- Analysis of your load profile and connection capacity.
- Sizing of power and capacity for your goals.
- Integration with PV, EV charging and building systems.
- Installation, commissioning and remote monitoring.
