DEYE Wireless CT SUN-SMART-CT01 with three current transformers

DEYE Wireless CT SUN-SMART-CT01is an intelligent wireless current transformer designed for precise measurement and monitoring of electricity in single-phase and three-phase systems. Thanks to LoRa communication, the device provides extremely low latency and reliable operation even in the absence of an Internet connection.

The model is a key component ofDEYE Wireless Energy Management Systemand allows efficient management of own consumption, limitation of export to the grid (Zero Export), as well as intelligent management of loads and EV charging stations.
