Applications
Home energy storage systems, commercial power supply systems, industrial power supply systems, etc.
Features
- Integrated design offers high integration and saved installation space.
- The use of high-performance lithium iron phosphate battery cells allows for a service life of more than 10 years.
- Master-slave mode and passive equalization ensures to manage equalization resistors, set equalization start voltage difference, and monitor equalization resistor temperature.
- The BMS uses high-performance automotive-grade chips from NXP in the United States, with SOC automatic calibration and high-current passive balancing function.
- CAN communication interface offers strong real-time performance, long transmission distance, and strong anti-electromagnetic interference ability.
- LiFePO4 battery energy storage system can be integrated with solar controllers, grid chargers, charging piles, and online communication control.
- Battery temperature management allows to automatically control the battery cells to work at the most suitable temperature with air conditioners and heaters according to the battery cell conditions, and can be linked with fire protection systems as needed;
- Built-in BMS management system comes with comprehensive protection and monitoring control functions.
- The main control MCU allows for easy centralized control, and managing the peripheral settings (AC charging module, inverter module, solar charging module) to adjust the peripheral device charging current and voltage according to the battery charging curve.
- EMS energy management system, BMS and solar controller, inverter centralized management of charge and discharge guarantees effectively controlling of the charge and discharge current within the battery cell usage conditions, and protecting the battery cell to extend its service life.
