Shelly PRO 3EM

With the Shelly PRO 3EM WiFi Energy Meter, you can wirelessly or via Ethernet cable easily and accurately monitor and record energy consumption for 3-phase or 3x single-phase systems, such as your solar panels. What's new with the Shelly PRO 3EM includes a fast ESP32 chip, support for both WiFi and LAN connections, and of course, a DIN-Rail version. Its open-source nature ensures that your Shelly 3EM can integrate with nearly any home automation system. Shelly also offers its own free app that lets you easily and affordably set up a Smart Home System without the cost of a Gateway/Hub. Additionally, you can also choose its more affordable predecessor, the Shelly 3EM.

The Shelly PRO 3EM can monitor 3-phase or up to 3 groups;
3x Power (W) measurement
3x Energy (Wh) measurement
3x Load (max. 120A) measurement
3x Load Quality measurement
1x Voltage (V) measurement
Additionally;
60 days of built-in energy (Wh) history per minute

Install the Shelly PRO 3EM according to the instructions, connect to your home WiFi (optionally via Bluetooth) or LAN using the free Shelly App, and pair the Module. It couldn't be simpler! The Shelly PRO 3EM Energy Meter operates at 110-240VAC and has a built-in ESP32 with a 16MB flash chip. This allows you to flash your own or alternative firmware. Currently, work is underway on a 120A terminal for the phase N connection. The current version is not suitable for this! We will, of course, update you once it is available.
Note, the CT clamps are quite large at approximately 30x30x45mm, but they can be opened to install over the phase wires without detaching them.

With the Shelly Pro 3EM, you can create scenes to control other Shelly devices based on power consumption or power return. Ideal for this purpose is the new Shelly Pro 3EM Switch Add-On, which also features DIN-Rail mounting and clicks onto the Pro 3EM. Afterward, you can directly control the potential-free relay up to 2A with a maximum of 240VAC or 30VDC from the Shelly Pro 3EM.

Prefer not to use the free Shelly cloud service but still want to control your devices remotely? No problem. The Shelly PRO 3EM also supports basic MQTT (Message Queue Telemetry Transport) for reliable connections via a central mediator: the MQTT broker. The involved devices communicate only with the broker and do not need to know each other's IP addresses or technical details. Thus, it's safe and reliable, with real-time monitoring and easy integration. Want to know more? Check out our Shelly WiFi Switch Blog.
