FE-1PH-WIRELESS-METER-CT | Wireless bridge kit to connect the CHINT DDSU666 CT energy meter to compatible Fox ESS inverters without running RS485 cable.

Key Features

• Dedicated wireless link between CHINT DDSU666 CT meter and Fox ESS single-phase inverters.
• Ideal where a hard-wired RS485 connection is difficult, costly or impractical.
