Hybrid ESS Cabinet

Applications

Commercial & Industrial (C&I) Energy Solutions

• Peak Shaving & Demand Charge Reduction: Ideal for factories, data centers, and retail facilities to optimize energy costs by storing off-peak power and discharging during high-rate periods.
• Backup Power for Critical Loads: Ensures 99.99% uptime for hospitals, telecom hubs, and manufacturing plants, with rapid switch to off-grid mode during outages.

Renewable Energy Integration

• Solar/Wind Smoothing: Mitigates intermittency in PV and wind farms, providing stable power input to grids through intelligent charge/discharge management.
• Microgrid Systems: Enables standalone energy solutions in remote areas (e.g., islands, rural communities) with hybrid solar-diesel setups.

Grid Services & EV Infrastructure

• Frequency Regulation & Peak Load Shifting: Supports grid operators (TSO/DSO) with fast-response energy storage for stability and auxiliary services.
• EV Charging Station Buffering: Reduces grid stress at high-power chargers by absorbing peak loads, optimizing energy costs for EV fleet operators.

Industrial Power Quality Optimization

• Reactive Power Compensation: Improves power factor (>0.99) and reduces harmonic distortion in industrial zones, enhancing efficiency and compliance with grid standards.

Optional Multiple Configurations
