xDescription
The FoxESS 10kW Hybrid Inverter & 18.64kWh High-Voltage Battery bundle is a high-performance energy storage solution designed for large single-phase residential homes.
This bundle includes a Fox KH10 single-phase hybrid inverter and a set of EQ4800 series high-voltage stackable batteries. The KH10 inverter features 4 MPPTs — a leading configuration in its class — effectively addressing complex roof orientations and shading challenges. The EQ4800 battery adopts safe Lithium Iron Phosphate (LiFePO₄) cells and supports modular expansion with system efficiency exceeding 95%. This bundle significantly increases PV self-consumption while providing EPS (Emergency Power Supply) functionality, automatically powering critical home loads during grid outages to ensure 24/7 energy security.
