With 51.2V nominal voltage and 1256Ah capacity, this battery provides approximately 64.30kWh of energy storage.
The large capacity makes it suitable for storing excess solar energy during the day and supplying power during the evening, at night, or during grid outages.
It is an excellent choice for customers who need a large-capacity residential battery system without using multiple small battery modules.
This model uses EVE 628Ah LiFePO4 cells in a 16S configuration to achieve the 51.2V system voltage.
LiFePO4 chemistry offers excellent thermal stability, high safety, long cycle life, and reliable performance for long-term energy storage applications.
The high-capacity 628Ah cells also help reduce the number of individual cells required for a large-capacity ESS, making the overall battery system more integrated and practical.
The integrated 300A BMS is designed for high-power energy storage applications.
It provides battery protection and monitoring functions while supporting high-current charging and discharging.
The built-in active balancer helps redistribute energy between cells and maintain better cell voltage consistency, supporting stable battery performance and extending the usable service life of the battery pack.
Maximum Charging Current: 300A
Maximum Discharging Current: 300A
Maximum Pulse Current: 350A (<3s)
The battery system supports connecting multiple units in parallel for larger energy storage requirements.
Up to 15 battery units can be connected in parallel, allowing the total system capacity to be expanded according to the user's energy requirements.
This makes the system suitable for:
Please ensure that the inverter and system configuration support the required parallel battery setup before installation.
The battery features a new enclosure design with four integrated wheels, making it easier to move the unit during installation, positioning, and maintenance.
The mobile design is particularly useful for large-capacity batteries that may need to be repositioned during system installation.
