Fox ESS EK6: Compact High-Voltage Efficiency with Integrated Design

The Fox ESS EK6 is a powerful, scalable battery storage system that impresses with its innovative, integrated design. Based on extremely safe LiFePO4 (LFP) technology, it offers high energy density in a compact form. The system is specifically optimized for seamless operation with Fox ESS inverters in the H1, KH, H3, H3-Pro, and H3 Smart series, enabling efficient solar energy storage for self-consumption.

With a nominal capacity of 5.76 kWh per unit, the EK6 provides a solid energy foundation even in its basic configuration. The system grows with your needs: up to 4 units can be connected in parallel to achieve a maximum storage capacity of 23.04 kWh. Thanks to its IP65 protection class and high temperature tolerance, the system is perfectly suited for both indoor and outdoor installation. A 90% depth of discharge (DoD) ensures that nearly all of your stored energy is available for use.

Highlights of the EK6 System

  • Integrated design: Quick and easy plug & play installation due to its compact design.
  • Scalable performance: Parallel connection of up to 4 modules for maximum flexibility.
  • High safety: Durable LiFePO4 cells with high cycle stability of up to 25,000 cycles (according to manufacturer specifications).
  • Maximum capacity utilization: High depth of discharge of 90% (DoD).
  • Weatherproof housing: IP65-certified for use in various conditions.
  • Smart communication: Equipped with a CAN interface for optimal system monitoring.
