FoxESS EK12 High-Voltage Battery Storage System

Fox ESS EK12: Maximum high-voltage capacity in an integrated design

The Fox ESS EK12 is a highly efficient, scalable battery storage system, specifically developed for demanding home applications and commercial operations. Thanks to its innovative, integrated design, it offers exceptional energy density with a minimal footprint. The system is based on proven LiFePO4 (LFP) technology and is optimized for seamless integration with Fox ESS inverters of the H1, KH, H3, H3-Pro, and H3 Smart series.

With a nominal capacity of 11.52 kWh per unit, the EK12 provides a significant amount of energy even as a single module. For growing requirements, up to 4 units can be connected in parallel, allowing for an impressive total capacity of 46.08 kWh. The robust housing with IP65 protection class ensures safe operation both indoors and outdoors. A high depth of discharge of 90% (DoD) guarantees that the stored energy can be used almost entirely for self-consumption.

Highlights of the EK12 system
