Commercial and industrial energy storage
iFreezer
A 218 kWh cabinet that trims peak demand and keeps critical loads running when the grid fails.
- Stored energy
- 218kWh
- AC power
- 100kW
- Depth of discharge
- 95%
Overview
Lower peaks, steadier supply.
It charges when power is cheap and discharges at peak times to cut demand charges, and switches to off-grid operation without a break if the grid fails. Add cabinets in parallel as the load grows.
All in one cabinet
- PCS and BMS already inside
- IP55 enclosure
- Simple to install and service
Safe and reliable
- BMS and EMS control
- Overheat, short-circuit and overvoltage protection
- Gas suppression with smoke and heat detection
Many uses
- Peak shaving and valley filling
- Backup for critical loads
- Cabinets connect in parallel for more capacity
Where it is used
- Factories and plants
- Commercial buildings
- Backup for critical loads
