Fox ESS Wireless Transmitter & Receiver (FE‑1PH‑WIRELESS‑METER‑CT)
The Fox ESS Wireless Meter (Part No: FE‑1PH‑WIRELESS‑METER‑CT) is a state‑of‑the‑art transmitter & receiver unit designed to work seamlessly with the CHINT DDSU666 CT meter. It’s included with all single‑phase Fox hybrid and AC inverters and provides a wireless alternative to wired CT metering. Ideal for installations where running cables is difficult or where flexibility is required.
Key Features
-
Wireless Communication — Transmits meter data over wireless link, reducing need for conduit or cable routing.
-
Integrated with Smart Gateway — Works together with the Fox ESS Smart Gateway (SMG666‑1PF1‑L1) for centralised, intelligent monitoring and control.
-
Plug‑and‑Play Compatibility — Specifically uses the CHINT DDSU666 CT meter (supplied with Fox single‑phase inverters) so installation is simple and reliable.
-
Improved Aesthetics & Flexibility — With no need for physical wiring between meter and inverter or gateway, you can achieve neat, flexible installations.

| Wireless Range |
Up to 300 metres (line of sight) intralink communication |
| Limitations |
Actual range depends on environmental factors; walls, metal obstructions, electrical noise may reduce range significantly |
| Compliance |
Not G100‑compliant—if export limitation (G100) is required, a wired CT/metering solution must be used to satisfy DNO or regulatory standards |
Important To Note
Range Considerations
While the wireless transmitter/receiver can communicate at distances up to 300 m under ideal conditions, real‑world installations often involve obstructions (walls, metal structures, electrical equipment) that degrade the signal. Expect reduced effective range in typical UK domestic or commercial settings.
G100 / Export Limitation Use
If your installation requires export limitation (commonly under the UK’s G100 standards), this wireless solution will not meet those requirements. For export control or to comply with DNO mandates, you must employ a wired CT/metering option. The wired solution ensures precise control and compliance with grid export rules.
