-
The Shelly Pro 3EM is a smart 3-phase energy meter from Shelly’s innovative product line. It lets you monitor and manage incoming power and consumption, with full readings in the app (available in Hebrew) and a year of history stored free of charge in the cloud and on the device itself. Installation is quick and simple, with a direct connection to your Wi-Fi network. Read the meter remotely, break down consumption by day, week, month or custom date range, and download the data as a CSV file. Its secure, open communication protocol lets it integrate with third-party control systems and push data to CRM systems, email and more.
Built-in protection against short circuits and excess consumption, with the option to cut power according to your settings. The meter can drive a contactor to control the power supply (requires an add-on).
Typical applications:
- EV charging stations
- Homes and apartments
- Industrial machinery
- Offices and industrial buildings
- 5-year manufacturer’s warranty

Who it’s for
For anyone who wants to see exactly how much electricity the home uses, how much a solar system produces or how much the electric car draws while charging, in a 3-phase electrical panel. The meter mounts on the DIN rail in the panel and measures up to 120 A per phase. For a single-phase panel or a tight space, Shelly 3EM-63T Gen3 is a better fit, and for especially large loads there’s the 400 A version.
What to know before installing
- Takes up one module on the DIN rail in the electrical panel.
- The three current transformers (120 A) are included in the kit and clamp around the cables without disconnecting them.
- Network connection: Wi-Fi or Ethernet. In a metal panel, Ethernet is more stable.
- Installed in the electrical panel by an electrician.
FAQ
Can it measure solar production and consumption together?
Yes. Metering is bidirectional, and the app shows how much you drew from the grid and how much you fed back.
Can I set a time-of-use rate?
Yes. Set electricity prices by hour in the app and see what your consumption cost. We have a guide to setting electricity rates.
Can the meter cut power?
Not by itself. With the dry-contact add-on it drives a contactor, for example to disconnect a charging station when consumption crosses a threshold.
