Deye - LoRa Wireless smart meter

Deye - LoRa Wireless smart meter 

SKU: SUN-SMART-CTU2-L

The Deye - LoRa Wireless smart meter (SKU: SUN-SMART-CTU2-L) is a compact, DIN-rail mounted bidirectional energy meter engineered for wireless current transformer (CT) monitoring and zero-export control in Deye solar and storage systems. Supporting single-phase, split-phase, and three-phase electrical connections, this smart meter eliminates the need to run long RS485 communication cables between the switchboard and inverter by transmitting real-time metering data over long-range 920 to 928 MHz LoRa wireless communication up to 200 metres. Featuring an integrated LCD screen, high-precision measurement accuracy, and dual LoRa and RS485 interfaces, the SUN-SMART-CTU2-L streamlines installation while enabling synchronized zero-export control and remote monitoring via Deye Cloud.
