xDescription
The FoxESS 10kW Three Phase Hybrid Inverter & 18.64kWh High-Voltage Battery bundle is a high-efficiency energy storage solution designed for three-phase residential and light commercial applications.
This bundle includes a Fox H3-10.0-E three-phase hybrid inverter and a set of EQ4800 series high-voltage stackable batteries. The H3 series inverter is a high-performance three-phase inverter featuring a 1000V high PV input voltage and maximum efficiency of 98.0%, significantly increasing PV self-consumption. The EQ4800 battery adopts safe Lithium Iron Phosphate (LiFePO₄) cells and supports modular expansion with a round-trip efficiency exceeding 95%. This bundle also provides EPS (Emergency Power Supply) functionality, automatically powering three-phase critical loads during grid outages to ensure 24/7 energy security.
