WHY SHELLY 3EM?

Smart 3-phase electricity meter and contactor control

Many devices, households, and buildings consume more energy than they need, leading to energy waste and higher costs. Shelly 3EM is a smart electricity meter that helps monitor power consumption in real time and notifies you if the consumption of a device or system exceeds a preset threshold. Additionally, it allows contactor control. Smart power measurement helps you identify and avoid redundant energy consumption.

2-WAY ENERGY CONSUMPTION MONITORING

Monitor your home, office, or workshop and avoid extra costs or voltage drops that can damage your devices and systems. Shelly 3EM can calculate 2-way consumption: produced and consumed energy for each of the three phases. The device can be configured to measure three separate circuits of a single-phase electrical system and control a contactor. View the quality of your power grid in terms of active power, reactive power, voltage, and power factor.

INTELLIGENT AND EFFICIENT VEHICLE CHARGER

Shelly 3EM is designed to monitor one, two, or three phases, allowing you to observe the status and history as well as the current and past power consumption of each channel for the day, week, month, or year. Shelly 3EM exports all data in CSV format at 10-minute intervals, simplifying data analysis and cost reduction. This way, you can monitor the exact energy consumption of your electric car and calculate its share of your electricity bill.

MONITORING AND CONTROL OF SOLAR PANELS

Track how much energy your solar panels and wind turbines generate and save effortlessly. Shelly EM provides real-time information on the efficiency of your solar and wind energy system as well as historical data on how much energy was generated and consumed. This helps you control energy flow and get the most out of your solar modules and wind turbines. To take it a step further, connect a contactor to Shelly 3EM so you can automatically turn off devices in your home that you don’t necessarily need to save energy.

PREVENTIVE MANAGEMENT

When an electrical device is damaged, it doesn’t just stop working. Usually, it increases energy consumption to compensate for its operating capacity. Since there is no visible performance difference, it can take months before you notice a problem, leading to inefficiency and energy waste. Shelly 3EM Power Monitoring immediately detects the increase in energy consumption and notifies you, saving you additional costs for repairs or device replacement.
