Shelly EM is Shelly's single-phase power meter, recommended for both domestic and commercial use. Shelly ЕМ can monitor energy consumption in real time in 2 points simultaneously (up to 120A each). With Shelly EM you can also measure how much energy your solar system is producing and energy consumption at the same time.
It can automatically shut down the entire circuit if consumption or energy (prepaid energy option) reaches the set limit and has built-in relay output for contactor control.
