Product Description
1. Basic Energy Storage Capacity & Application Scenarios
This energy storage system is installed in a standard 20ft high-cube container with a high-density energy storage capacity of 4.34 MWh. It adopts advanced 314Ah high-voltage LFP cells to deliver stable power for utility-scale energy storage, peak shaving and microgrid projects.
2. Modular PCS & PV DC Coupling Performance
Matched with a 2.25MW modular PCS (Model WS-PCS2250-2-A) packed in a compact 10ft container. The system supports up to 2,880kW PV DC coupling with 144 MPPT trackers (18×8 layout), which maximizes solar capture and overall system efficiency.
3. Comprehensive Multi-layer Safety Protection System
An integrated 3+3 safety protection structure is adopted. It is equipped with dual fire suppression systems (aerosol + water mist), active ventilation, AC leakage detection, DC insulation monitoring and high-voltage interlock protection. A six-tier battery management system covers monitoring from individual cells to the whole unit for full operational safety.
4. Cell-level Liquid Cooling & Thermal Consistency
Equipped with advanced liquid cooling at cell level. The temperature difference between all batteries is controlled within 3°C. Uniform thermal performance prolongs cycle life of batteries and boosts long-term investment benefits.
5. Harsh Environment Adaptability & Wide Application Range
The unit is built for severe outdoor conditions with IP55 protection rating and C4-M marine anti-corrosion coating (C5 coating optional). Its operating temperature ranges from -30°C to +50°C. It fits grid-scale energy storage, commercial energy management and solar-diesel-storage hybrid systems.
