Shelly 3EM PRO 120A
Monitor loads up to 120A per phase (clamps suitable for active cables up to 16mm in diameter).
Shelly 3EM PRO 400A
Monitor loads up to 400A per phase (clamps suitable for active cables up to 35mm in diameter).
Industry-grade security.
Shelly Pro 3EM supports mTLS for MQTT, HTTP, and secure outbound WebSockets. Its industry-grade security allows for direct connections to your cloud infrastructure, reducing the cost of deploying complex networks and VPNs.
Industrial installations.
Shelly Pro 3EM brings support for MODBUS for voltage, current, power, and energies. You can accurately sample your energy usage and instantaneous values of voltage, current, and power. Our new firmware platform allows for custom implementation that can report as fast as every 100ms to your infrastructure.
Local control.
Thanks to Shelly Pro 3EM’s scripting functionalities and webhooks, you can now easily control other Shelly or Wi-Fi devices on your local network. Use these capabilities to set exact parameters for HVAC, pool pumps, electric vehicle charging, etc – based on solar production. All without using “the cloud”.
Solar panel monitoring.
Keep track of how much energy your solar panels or wind turbines are generating. Shelly Pro 3EM provides real-time information about the efficiency of the solar and wind energy system, as well as historical data on how much energy has been generated and consumed every minute for the past 60 days.
Energy monitoring.
Monitor your home, office or factory – and avoid additional expenses or drops in voltage that can damage your appliances and devices. Shelly Pro 3EM can calculate 2-way consumption: produced and used energy for each of the three phases. The device can also be configured to measure three separate circuits of a mono-phase electrical system.
