The Shelly 3EM-63T Gen3 is an advanced three-phase energy meter specifically designed to accurately monitor electrical energy consumption on three separate phases or three independent single-phase circuits. Thanks to its compact design, it can be installed directly in the electrical cabinet, either above or below the circuit breaker, so it does not take up a separate module space in the electrical cabinet. An ideal choice for both home and industrial applications.

The device provides real-time data on voltage, current, power and power factor, allowing users to optimize their energy use and reduce costs. Thanks to the built-in Wi-Fi and Bluetooth connections, you can use it with Shelly's cloud smart system, but it can also be easily integrated into other smart home systems, supporting completely local or cloud-based control.

The Shelly 3EM-63T Gen3 also supports the monitoring of photovoltaic systems, making it an ideal solution for those who want to monitor and optimize their solar energy production. The device performs a 4-quadrant measurement, which ensures accurate measurement of energy consumption and production on all three phases.

Local data backup or cloud-based data backup

The Shelly 3EM-63T Gen3 has a built-in memory that allows energy consumption data to be stored directly on the device. You can access the data via the built-in web interface, so you can monitor consumption even without an internet connection. This can be especially useful in places with limited or no internet access. Of course, if you want, the device can also upload the data to Shelly Cloud. This enables longer-term data storage and remote access, as well as integration with other smart home systems.
