500kW 1.5MWh energy storage system
Integrated Energy Storage Architecture
The containerized system combines battery storage, power conversion, energy management, and thermal management in an integrated enclosure. Its standardized design helps simplify equipment arrangement, transportation, installation, and system commissioning.
Battery Technology and Thermal Management
The system uses lithium iron phosphate (LFP) battery cells with a nominal cell capacity of 314Ah. Intelligent air cooling supports battery thermal management during operation. The 0.5C rated charge/discharge rate provides a basis for evaluating the system’s energy storage and power delivery capabilities.
Solar PV and Grid Integration
With support for an external MPPT controller, the system can be configured for solar PV and battery storage projects. Depending on the project design, it can support renewable energy utilization, energy storage, and coordinated power supply to local loads.
Grid-Connected and Backup Applications
The integrated grid/off-grid switching function supports applications that require a transition between operating modes. The specified switching time is less than 20ms. Actual backup performance, transfer behavior, and supported loads should be verified against the complete system configuration.
Project-Specific Configuration
System design can be tailored to project requirements, including PV input capacity, PCS configuration, battery capacity, grid connection, backup loads, and energy management strategy. Contact our technical team to discuss system sizing and project compatibility.
