【Large 64.30kWh Energy Storage Capacity】

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.

【EVE 628Ah LiFePO4 Battery Cells】

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.

【300A BMS + Active Balancing】

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)

【Up to 15 Units in Parallel】

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:

• Large residential solar systems
• High-consumption homes
• Off-grid energy systems
• Solar backup systems
• Farms and workshops
• Emergency backup power
• Large-scale residential energy storage

Please ensure that the inverter and system configuration support the required parallel battery setup before installation.

【Easy to Move & Install】
