Deye SUN-SMART-SWITCH01P3 Smart Switch Single/Three-phase 25A LoRa
The SUN-SMART-SWITCH01P3 is the smart switch that lets a Deye hybrid inverter turn home or business loads on and off over the air. It handles up to 25A per phase in single- or three-phase configuration and communicates over LoRa at 863–870 MHz with roughly 200 m barrier-free range.
Its job is to separate essential loads from deferrable ones: water heaters, heat pumps, pool pumps, ovens, machines and irrigation systems start when there is solar surplus or when energy is cheaper, and drop out automatically on grid failure. It needs the SUN-SMART-TX01 transmitter on the inverter and combines with the SUN-SMART-CT01 energy meter, SUN-SMART-PLUG01P1-F plugs and SUN-EVSE wallboxes.
