1MWh Industrial & Commercial Energy Storage System: Powering Sustainable Operations

Application Scenarios

Peak Shaving & Cost Optimization

Industrial facilities leverage its rapid grid response (<100ms) to shift energy consumption from high-tariff peak periods (e.g., 10 AM–7 PM) to off-peak hours, reducing electricity costs by up to 40%.Factories in China’s Guangdong Province using similar systems achieve ROI within 4 years through daily two-cycle charge/discharge operations

Renewable Energy Integration

Compatible with solar/wind farms, the system stabilizes intermittent renewable output via DC coupling. A Thailand solar park deployment demonstrated 98% renewable self-consumption by storing excess daytime solar energy for nighttime operations

EV Charging Infrastructure

Supports fast-charging stations in urban hubs by balancing grid load, reducing demand charges, and enabling 500kW–1.29MW power output without grid upgrades

Mission-Critical Backup

Provides 72+ hours of emergency power for hospitals, semiconductor fabs, and data centers during grid outages, ensuring 99.999% uptime
