• Photovoltaic ready
• Phase sequence error detection* (option)
• Optical pulse indication of power consumption
• Measuring accuracy up to 1%
• Stores data in non-volatile memory that can be retrieved for up to 60 days at 1-minute intervals
• Package includes 3 pieces of 400A current transformers

The Shelly Pro 3EM is a three-phase, Wi-Fi-operated, DIN-mountable, three-phase energy meter with Wi-Fi, Bluetooth and LAN connectivity. With an active energy measurement accuracy of 1%, the Shelly Pro 3EM can be used to individually monitor the consumption of any home appliances, electrical circuits and office equipment. It features 60 days of historical data per device, with 1 minute resolution for each phase. In addition, its scripting functionalities allow the execution of complex scenes and provide broader monitoring capabilities. Shelly Pro 3EM supports mTLS for MQTT, HTTP and secure outbound WebSockets. Its industrial-grade security enables direct connections to your cloud infrastructure, reducing the cost of deploying complex networks and VPNs. Shelly Pro 3EM offers MODBUS support for voltage, current, power and energy. You can accurately sample power consumption and instantaneous voltage, current and power values. Our new firmware platform enables custom deployments that can report every 100 ms to your infrastructure. Monitor your home, office or factory and avoid extra expenses or brownouts that can damage your appliances and devices. The Shelly Pro 3EM can calculate consumption in two ways: energy produced and used for each of the three phases. The device can be configured to measure three separate circuits of a single-phase electrical system. Visualize the quality of your electricity network in terms of active power, reactive power, voltage and power factor. With Shelly Pro 3EM's scripting and webhook capabilities, you can now easily control other Shelly or Wi-Fi devices on your local network. Use these capabilities to set exact parameters for heating, cooling or charging electric vehicles based on PV output and have your devices automatically reduce power consumption. All this works without using a cloud. Track how much energy your solar panels or wind turbines generate and save effortlessly. The Shelly Pro 3EM provides real-time information about the efficiency of your solar and wind energy system, as well as historical data about how much energy has been generated and consumed every minute for the last 60 days. This helps you control the energy flow, making the most of your solar panels and wind turbines. To take it a step further, connect the Shelly Pro 3EM to your other Shelly devices and create scenes to trigger desired actions, such as turning off appliances or sounding alarms.
