A 1MWh Battery Energy Storage System is an ideal solution for commercial and industrial facilities seeking peak shaving, backup power, and renewable energy integration.
The E10FT1044LP-2 is a fully integrated 1.044MWh containerized Battery Energy Storage System (BESS) designed for commercial and industrial applications. Operating at a rated voltage of 400V, the system integrates battery packs, BMS/EMS/PCS control systems (3S), liquid cooling, fire protection, and Static Transfer Switch (STS) technology into a compact 10ft container.
Designed to support Solar + Storage + Diesel Generator hybrid applications, the system delivers a safe, flexible, and turnkey energy storage solution for peak shaving, backup power, microgrids, and renewable energy integration.
Flexible On-Grid and Off-Grid Operation
The system can be seamlessly integrated with POC cabinets, EPS cabinets, and STS cabinets, supporting both grid-connected and off-grid operating modes. This enables flexible energy management and reliable operation in complex microgrid environments.
Fully Integrated Plug-and-Play Design
The system integrates battery management, energy management, liquid cooling, and multi-level fire protection into a single pre-engineered solution. Factory pre-assembly and testing significantly reduce on-site installation time, commissioning effort, and project costs.
UPS-Level Backup Power with 20ms Transfer Time
Equipped with a high-performance STS, the system can switch between grid and off-grid operation within 20 milliseconds during grid disturbances, providing UPS-level power continuity for critical loads, sensitive equipment, and production lines.
Advanced Safety and Battery Management
The independent battery cluster management architecture enables real-time monitoring, dynamic balancing, and rapid fault isolation. This improves operational safety, maximizes usable battery capacity, and extends system service life.
Peak Shaving & Energy Cost Reduction
Store electricity during off-peak hours and discharge during peak demand periods to reduce energy costs, optimize electricity bills, and defer transformer capacity upgrades.
Off-Grid and Remote Microgrids
Ideal for mining sites, islands, rural communities, and other weak-grid or off-grid locations. Combined with solar PV and diesel generators, the system reduces fuel consumption and improves energy independence.
Emergency Backup Power
Provides ultra-fast backup power for data centers, telecommunications infrastructure, hospitals, commercial facilities, and precision manufacturing plants, ensuring uninterrupted business operations.
Renewable Energy Integration & Grid Support
Mitigates solar and wind power intermittency, improves power quality, enhances grid stability, and increases the local consumption of renewable energy.
