Product description
The Solis SMG666-1PF1-L1 Smart Gateway is a wireless RS485 gateway that links a Solis inverter to its electricity meter without a wired connection, cutting installation cost and complexity where a meter cable run is difficult. It works as a pair — one unit as AP (master) at the inverter, one as STA (slave) at the meter — bridging RS485 over 868 MHz wireless (IEEE 802.11ah) at up to 200m transmission distance. Each DIN-rail mounted module runs on 85–277 Vac at just 2W, operates across −25 to +55 °C, and uses an external antenna for stable signal. It supports Solis S6 hybrid inverter series (subject to firmware version; see Solis documentation for compatible models).
