Shelly WiFi Three-Phase Consumption Meter with 3 CTs and Wires - Shelly 3EM-63W Gen3

The Shelly 3EM-63W Gen3 is a smart three-phase energy meter designed to accurately monitor electricity consumption in residential, commercial, and photovoltaic production installations. Thanks to its three built-in current transformers (CTs) and color-coded wires, it allows for easy and quick installation, ideal for compact electrical panels with DIN rail. It can be used in both three-phase systems and three independent single-phase circuits.

This device stands out for its high accuracy and local operating capability, without the need for cloud connection, although it supports integrations with cloud platforms through protocols such as MQTT, HTTP, and WebSocket. With WiFi and Bluetooth connectivity, the Shelly 3EM-63W Gen3 offers great flexibility in the configuration and control of energy consumption in real time.

In addition, it stores data locally with a one-minute resolution for up to seven days, allowing for detailed analysis even in the event of network failures. It is compatible with photovoltaic systems and features advanced functions such as measurement in four quadrants, phase sequence error detection, and support for custom scripts, making it a robust solution for any energy management scenario.
