Article description Shelly Pro 3EM:

Smart WiFi electricity meter for 3 phases

The Shelly Pro 3EM is a WLAN-powered, DIN-assembled 3-phase current consumption measuring device with WLAN, Bluetooth and LAN connectivity. With its 1% accuracy of energy resistance to 1%, the Shelly Pro 3EM can be used to monitor the consumption of all household appliances, circuits and office equipment individually. Historical data is saved for up to 60 days, with each phase has a one -minute resolution. In addition, the scripting functionalities allow the execution of complex scenarios and offer extended surveillance options.

monitoring and control of solar collectors: observe how much energy your solar collectors or wind turbines generate - savings effortlessly. Shelly Pro 3EM provides you with real-time information on the efficiency of your solar and wind energy system as well as historical data for generation and consumption of energy in the past 60 days- in one-minute sections. So you can control the flow of energy and use your solar collectors and wind turbines most efficiently. In a further step, you can link Shelly Pro 3EM to your other Shelly devices and create scenarios to trigger desired actions such as switching off household appliances or triggering an alarm.

Security at a commercial level: Shelly Pro 3EM supports MTLs for MQTT, HTTP and secure outgoing website. Security at a commercial level enables direct connections to your cloud infrastructure and reduces the cost of providing complex networks and VPNs.

industrial facilities: Shelly Pro 3EM offers support for modbus for tension, electricity, performance and energies. Their energy consumption and current values ​​of voltage, electricity and performance are precisely captivable. Our new firmware platform enables user-defined implementation that can make your infrastructure all 100 ms of message.

two-way energy consumption monitoring: Thanks to the scripting functionalities of the Shelly Pro 3EM and webhooks, you can easily control other Shelly or WLAN devices in your local network. Use these functions based on your PV generation to set precise parameters for heating, cooling or charging electric vehicles and automatically separate your devices from electricity consumption. All of this works without having to use a cloud.

Local control: monitor your home, office or factory to avoid unnecessary expenses or voltage waste that can damage your household and office equipment. With the Shelly Pro 3EM you can calculate the two -way consumption, both the produced and the energy used for each of the three phases. The device can also be configured to measure three separate circuits in a single -phase electrical system. It shows you the quality of your power grid in terms of effective power, reactive power, voltage and performance factor.

Functions:

photovoltaics - suitable for photovoltaics

4-quadrant measurement- for measuring the capacitive and inductive load types of imported and exported activity energy.

accuracy class B (work energy) - The Shelly Pro 3EM has a measurement accuracy of 1%. (Compliance with IEC 62053-21 based on manufacturer tests)

WLAN, LAN and Bluetooth connectivity- simultaneous Ethernet and WLAN use. MQTT, incoming and outgoing website, UDP, MTLS support.

Modbus support - allows simple and fast use in existing industrial plants.

power grid monitoring - monitors monitored single -phase electrical systems with up to 3 points at the same time. Fast notifications and at least 60 days 1 minute recording storage.

scripting functionalities- Shelly Pro 3PM fully supports MJS scripting, which enables you to create further functions and functionalities.

data storage- memory that can be called up over a period of up to 60 days in 1-minute intervals

Article description Shelly Pro 3em Addon:

Add-on for Shelly Pro 3EM

A galvanically isolated switch that was designed to expand the possibilities of your Shelly Pro 3EM. With this additional device, protecting and other electrical devices can easily be controlled, which gives you more flexibility and control over your consumption.

load drop - keep an overview of how much energy your solar modules and wind turbines generate and save effortlessly by controlling your consumption with the Shelly Pro 3EM add -on. Connect the Shelly Pro 3EM add-on to your devices and use the real-time information from Shelly Pro 3EM via the generated and consumed amount of energy. If you have to save energy, the Shelly Pro 3EM add-on can automatically switch off devices that are not required in your house.

Weather -dependent control - Shelly Pro 3EM, expanded with the Shelly Pro 3em Add -on, enables weather -controlled energy optimization. With the help of scripts, you can efficiently control your devices based on the weather forecast. After receiving real-time weather data, Shelly Pro 3EM implemented the measures defined in the script. For example, the Shelly Pro 3EM add-on can automatically switch off the heating if the prediction shows a sunny day to avoid higher temperatures.

Compensation of PV systems -If your PV system produces more energy than your house consumes, the Shelly Pro 3EM add-on can automatically activate devices to use them excess energy. For example, you can set that your hot water rider, the charging station for electric vehicles or other energy -intensive devices will be switched on. This uses the energy generated by your PV system efficiently and reduce your dependency on the power grid.

The addon is only compatible with Shelly Pro 3em!
