Shelly EM 2-channel single-phase energy meter with contactor control

⚡ Shelly EM - 2-channel single-phase energy meter + meter relay output

Smart energy monitoring for homes, businesses and photovoltaic systems

Shelly EM is the ideal single-phase energy meter for automating and optimising electricity consumption in both residential and commercial premises. With two independent channels, the Shelly EM simultaneously monitors two circuits or compares the solar system's output with grid consumption. What's more, it includes dedicated relay output for controlling a meter, providing complete control over power flow.

Main features

🔌 2 energy monitoring channels (up to 120A each)
Controls and analyses two circuits separately - perfect for individual consumption and output management.

☀️ Photovoltaic compatible
Measures energy produced and consumed separately - ideal for optimising energy autonomy.

⚙️ Relay output for contactor control
Shelly EM can automatically switch off power when a consumption or prepaid energy limit is reached.

📊 A ccurate and complete measurements
✔️ Active power (W)
✔️ Current (A)
✔️ Voltage (V)
✔️ Energy consumed (Wh)
✔️ Energy generated (Wh)
