Shelly Pro 3EM V2 is a professional three-phase energy meter designed for monitoring electricity consumption and production in residential, commercial, and industrial installations. DIN rail-mounted, it provides precise bidirectional measurement of electrical parameters in real time.

The meter is ideal for photovoltaic systems, battery energy storage systems, and Energy Management Systems (EMS). Shelly Pro 3EM V2 is also compatible with Marstek energy storage systems, enabling energy flow monitoring and intelligent system control to maximize self-consumption and reduce energy exported to the grid.

The device supports Wi-Fi, Ethernet (LAN), and Bluetooth connectivity, allowing seamless integration with building automation systems, Smart Home platforms, and IoT solutions. Its built-in web interface enables quick local configuration without the need for an additional hub.

Shelly Pro 3EM V2 measures voltage, current, active power, apparent power, power factor, as well as imported and exported energy for each of the three phases. Support for MQTT, HTTP RPC, and WebSocket protocols, together with Shelly Scripting (JavaScript), makes it suitable for both simple installations and advanced automation systems.
