Parallel Operation of Four 5.12 kWh Lithium Batteries with 11 kW Easun Power Inverter

Efficient energy storage solutions are increasingly essential for both residential and commercial applications. Easun Power provided a system using four 5.12 kWh lithium batteries in parallel (totaling 20.48 kWh) paired with an 11 kW inverter, delivering high performance, reliability, and intelligent energy management.

Project Background

The client sought a medium-capacity energy storage system to:

  • Maximize self-consumption of renewable energy

  • Ensure reliable and stable power supply for critical loads

  • Integrate multiple battery units seamlessly with a high-capacity inverter

By connecting four 5.12 kWh batteries in parallel, the system achieves a total usable capacity of 20.48 kWh, capable of supporting the 11 kW inverter for peak load management and backup purposes.

Solution

Easun Power implemented a parallel battery configuration with the 11 kW inverter, ensuring seamless operation:

  1. Parallel Battery Integration
    Four batteries are connected in parallel, balancing charge and discharge while maintaining optimal performance and extending battery life.

  2. High Compatibility with Inverter
    The 11 kW inverter communicates efficiently with the battery bank, handling energy flow intelligently to support loads and optimize self-consumption.

  3. Smart Monitoring
    Easun Power’s monitoring platform tracks real-time performance of each battery and the inverter, providing energy insights and alerts for preventive maintenance.

  4. Safety and Reliability
    The system features protection against overvoltage, overcurrent, short circuits, and automatic fault response, ensuring safe operation under all conditions.

Project Outcomes

After installation, the system achieved:

  • Stable and seamless parallel operation of four batteries with the 11 kW inverter

  • Optimized energy usage and reduced reliance on the grid

  • Reliable power supply for critical loads, even during outages

Conclusion

This project demonstrates that combining four 5.12 kWh batteries in parallel with an 11 kW inverter provides a flexible, reliable, and intelligent storage solution suitable for medium-capacity energy needs.
