Fox ESS · three-phase grid inverter
Fox ESS V Series inverter, 30–75 kW
Commercial class: IP66 rating and C5 anti-corrosion class, so it can go on the coast or next to plants with an aggressive atmosphere. Input current of up to 40 A per tracker is sized for large-format bifacial modules.
IP66 and C5 class
Dust and water-jet protection plus top-class anti-corrosion treatment: coastal sites, livestock complexes, chemical plants.
40 A per tracker
Sized for modern large-format bifacial modules, whose short-circuit current is noticeably higher than classic panels.
PID recovery
At night the inverter reverses potential-induced degradation in the modules, extending the life of the array.
Per-string monitoring
Every string current is visible in the app, and the AFCI function watches for arc faults on the DC side.
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.
