Product Details

The Shelly Pro 3EM is a DIN-rail three-phase energy meter built for whole-home and light commercial monitoring. With 120A current transformers it covers higher loads than the 63A version, reporting voltage, current and power per phase in real time at 1% accuracy.

It connects over Wi-Fi, Bluetooth and wired LAN, keeps 60 days of history on the device, and exposes MQTT and Modbus for dashboards and building systems. It calculates two-way energy, so it suits solar installations, and it can also monitor three separate single-phase circuits.

When you need accurate, panel-mounted energy data for a busy home or a small business, the Pro 3EM is the standard choice.
