FoxESS 18.64kWh EQ4800 Energy Storage & 10kW Single Phase Hybrid Inverter (KH 10KW inverter)

Description 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. Key Features Inverter Features 4 MPPTs: The KH10 inverter is equipped with 4 independent MPPT trackers, allowing connection of up to 4 PV arrays with different orientations to maximise energy harvest from complex rooftops. High Efficiency: Maximum efficiency reaches 97.8%, with MPPT tracking efficiency of 99.9%. EPS Backup Power: Supports 10kW rated EPS output with <10ms switching time during grid outages, ensuring continuous operation of critical home appliances. Parallel Expansion: Supports up to 10 units in parallel for flexible system capacity scaling. High Protection Rating: IP65 rated, operates in a wide temperature range of -25°C to +60°C, suitable for both indoor and outdoor installation. Smart Monitoring: Standard with WiFi/LAN/4G communication ports, supports FoxESS Cloud mobile app and web portal for real-time monitoring. Included Accessories: CT clamp and meter are included in the box for easy installation and measurement. Battery Features LiFePO₄ Technology: High thermal stability and long cycle life. Modular & Expandable: The 18.64kWh configuration consists of 1 master module + 3 slave modules, expandable up to 9 modules (41.93kWh total) . Deep Discharge Capability: Supports 100% Depth of Discharge (DoD) to fully utilise stored energy. High Efficiency: Round-trip battery efficiency >95%. High Voltage Design: Operating voltage range of 162.4–206.0V, enabling more efficient charge/discharge. Wide Temperature Adaptability: Charging temperature 0~55°C, discharging temperature -10~55°C.
