Reliable Base Station Backup Power
With 48.2kWh of rated energy and 942Ah capacity, the system provides dependable energy reserves for 5G and other communication base stations. During a grid interruption, it can support essential communication equipment and help maintain network availability until normal power is restored.
Grade A LiFePO4 Cells
Grade A lithium iron phosphate cells provide high safety, stable output, strong consistency and long service life. The 3.2V 314Ah cells are arranged in a 3P16S configuration to deliver reliable performance for frequent standby and cycling applications.
Modular and Easy to Maintain
Independent battery-enclosure modules and an optimized internal connection layout simplify installation, transportation and maintenance. The modular structure also makes inspection and component servicing more convenient at communication sites with limited working space.
Peak Shaving and Emergency Supply
In addition to emergency backup, the system can store energy during lower-load periods and discharge during peak demand. This enables peak shaving, reduces pressure on site power capacity and improves the utilization of installed energy-storage assets.
