FoxESS 18.64kWh EQ4800 Energy Storage & 5kW Single Phase Hybrid Inverter (H1 5KW inverter)

Description The FoxESS 5kW Hybrid Inverter & 18.64kWh High-Voltage Battery bundle is a high-efficiency, modular energy storage solution designed for modern homes. This bundle includes a Fox H1-5.0-E single-phase hybrid inverter and a set of EQ4800 series high-voltage stackable batteries. The H1 series inverter features advanced control technology and high efficiency, intelligently managing energy flow between solar panels, batteries, and the grid. The EQ4800 battery adopts safe Lithium Iron Phosphate (LiFePO₄) cells and supports modular expansion. It not only significantly increases PV self-consumption but also provides EPS (Emergency Power Supply) functionality, automatically powering critical home loads during grid outages, ensuring 24/7 energy security. Key Features High Efficiency & Flexibility: Max inverter efficiency reaches 97.8%, and battery system efficiency is 95%, minimising energy conversion losses. Expandable Capacity: The EQ4800 features a modular design. The 18.64kWh configuration consists of 1 master module and 3 slave modules. The system can be expanded up to 9 modules, reaching a maximum total capacity of 41.94kWh to accommodate future upgrades. EPS (Emergency Power Supply): Supports EPS output. In the event of a grid outage, the inverter switches to battery power in less than 20ms, ensuring essential home appliances continue running. Deep Discharge Capability: Supports 90% Depth of Discharge (DoD) , allowing you to make full use of every stored kilowatt-hour. Durable & Weather-Resistant: Achieves IP65 protection rating and operates in a wide temperature range from -25°C to +60°C, suitable for both indoor and outdoor installation in harsh environments. Smart Monitoring: Comes standard with WiFi/4G/LAN communication ports, enabling real-time system monitoring (generation, usage, savings) via a mobile app. Technical Specifications System Overview Parameter Specification Product Type Single-Phase High-Voltage Hybrid Storage System Application Residential PV self-consumption, peak shaving/arbitrage, backup power Inverter Model Fox H1-5.0-E (Gen 1 / Gen 2 compatible) Battery Model Fox ESS EQ4800 (4.66kWh modules x 4) Fox H1-5.0-E Inverter Specifications Parameter Category Details Input (PV) Max.
