289kWh Stars Series Cabinet ESS
Applications
Commercial & Industrial (C&I) Energy Management
Peak shaving, demand charge reduction, and backup power for factories, data centers, and retail facilities.
Renewable Integration
Stabilizing solar/wind power output and providing ancillary services for microgrids.
Critical Infrastructure
Uninterruptible power supply (UPS) for hospitals, telecom towers, and remote sites requiring high-altitude operation (up to 4,500m with derating).
EV Charging Buffering
Mitigating grid strain at high-power charging stations.
