Fox ESS · three-phase industrial inverter
Fox ESS R Series (G2) inverter, 75–136 kW
Industrial class for large roofs and ground-mounted plants: up to ten MPPT trackers in a single unit. The array can be split into ten independent groups, which protects yield on complex roof geometry and on tracker fields.
Up to ten trackers
Each string group runs at its own operating point: different pitches, different shading and different module ages do not interfere with each other.
For large sites
From 75 to 136 kW per unit — fewer devices per megawatt, a simpler switchroom and easier maintenance.
IP66 and smart cooling
Operates from −30 to +60 °C and up to 4000 m above sea level (with derating above 3000 m).
Industrial diagnostics
Per-string current monitoring, AFCI and PID recovery — problems show up in the app before they eat into yield.
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.
