Fox ESS · three-phase hybrid inverter
Fox ESS H3 & AC3 hybrid inverter, 5–12 kW
A three-phase hybrid with energy storage and a backup output. H3 works with a PV array, AC3 adds a battery to an existing grid-tied system. Up to ten inverters in parallel, so the system can grow with the site.
Three-phase backup
The EPS output holds up to 15 kVA and feeds three-phase loads — pumps, machine tools and ventilation, not just sockets.
Scales to 120 kW
Up to ten units in parallel: start with one and add more as consumption grows.
Three battery families
Compatible with three Fox ESS high-voltage battery lines, for a total capacity of up to 33.24 kWh.
98% efficiency
Peak conversion efficiency of 98.0%, PV-to-battery charging at 98.5% and battery-to-grid discharge at 97.0%.
Shipped from stock in Krasnodar across Russia. Send us the array size and grid phase configuration — our engineer will check the inverter selection and string layout before dispatch.
