Shelly Pro 3EM – Professional 3-phase DIN rail energy meter with Wi-Fi, LAN, Bluetooth, for advanced energy monitoring and analysis

Shelly Pro 3EM is a three-phase energy meter with DIN mounting, dedicated for professional applications in homes, offices, industry, renewable energy and commercial facilities. It offers precise measurement of energy parameters and network quality in 1- and 3-phase installations, 4-quadrant register and extensive data archiving, integration and export capabilities (LAN, Wi-Fi, Bluetooth, MQTT, Modbus TCP, webhooks).

Applications:

Advanced energy monitoring in residential, commercial and industrial buildings, analyzing energy production/consumption, controlling PV self-consumption, integration with automation, energy cost management.

Key features of the product:

• Measurement of 3-phase network values (or 3 single-phase lines): voltage, current, active and apparent power, power factor, energy consumed and rendered
• 4-quadrant measurement, accuracy class B (IEC 62053-21)
• Registration of historical data – every 1 minute for at least 60 days
• Support current transformers (CT, up to 120 A) included
• Cooperation with automation via LAN (RJ45), 2,4 GHz Wi-Fi, Bluetooth 4.2, MQTT support, Modbus, RPC, HTTP, webhooks, scripting
• Time synchronization by RTC clock (works even when the network goes down)
• Signal output and programming button, LED indicator
• Detection of wrong phase sequence, channel calibration, alarms
• Expandable with Shelly Pro 3EM Switch Add-on (contactor control)
• DIN mounting, solid, small housing
