Description
THREE-PHASE ENERGY METER 120A WITH WIFI, ETHERNET AND BLUETOOTH - Professional real-time monitoring for single-phase and three-phase installations
The Shelly Pro 3EM V2 is a three-phase energy meter for DIN rail mounting, designed to monitor energy consumption and production with class 1 accuracy (±1%). Triple communication (WiFi, Ethernet RJ45 and Bluetooth) and native integration with Home Assistant, Google Home and Alexa.
What it does
Measures accumulated energy, instantaneous voltage, current and power factor per phase in real time. Supports 4 measurement quadrants (consumption and production), ideal for photovoltaic systems and self-consumption. Integrated 60-day history without the need for cloud.
What it is for
- Real-time energy consumption monitoring (home, office, industry)
- Solar photovoltaic production control (grid injection vs self-consumption)
- Detection of anomalous consumption and optimization of contracted power
- Integration into automation systems via MQTT, REST API and Webhooks
Main features
- Three-phase measurement up to 120A per phase (3 current CTs included)
- 1% accuracy (Class 1) on all phases
- 4 measurement quadrants: import, export, inductive and capacitive reactive
- 60-day local history of energy data
- Triple communication: WiFi 802.11 b/g/n 2.4GHz, Ethernet RJ45, Bluetooth 4.2
- Open protocols: MQTT, CoAP, REST API, Webhooks, UDP
- Compatible with Home Assistant, Google Home, Alexa, SmartThings
- Standard DIN rail mounting (TE2 module)
- Direct power supply 110-240V AC
