Fox ESS · single-phase grid inverter
Fox ESS S Series (G2) inverter, 0.7–3.3 kW
The most compact single-phase Fox ESS range: seven ratings from 700 W to 3.3 kW in a 5.4 kg housing. A start-up voltage of just 60 volts means the inverter wakes up earlier than most and harvests more at dawn and on overcast days.
Very low start-up threshold
A 60 V start-up voltage against the typical 120–140 V: the array starts exporting earlier and stops later.
Fits anywhere
Five and a half kilograms in a 29×22 cm housing — one person mounts it, and it fits a narrow recess or a switchboard wall.
For small sites
Cabins, garages, kiosks, pump stations and lighting systems — wherever the array is only a few modules.
Weatherproof
IP65 and a −25…+60 °C operating range: it can go outdoors without an extra enclosure.
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.
