USE CASES

Compatible with V2C Trydan. Allows dynamic load balancing function via Wifi. NO DATA CABLES NEEDED. Preventative monitoring

When an electrical appliance is damaged, it doesn’t simply stop working. Usually, it increases the amount of energy used in an attempt to compensate for its operational capacity. Since there is no visible difference in its performance, it might take months before you can identify a problem, leading to inefficiency and wasted energy. Shelly 3EM power monitoring will immediately read the increase in energy consumption and will notify you, saving you additional expenses on repairs.

Solar panels monitoring and control

Keep track of how much energy your solar panels and wind turbines are generating and save effortlessly. Shelly 3EM provides real-time information about the efficiency of the solar and wind energy system, as well as historical data on how much energy has been generated and consumed. This helps you control the energy flow, getting the most out of your solar panels and wind turbines. To take it a step further, connect a contactor to Shelly 3EM, so you can switch off automatically non-essential devices in your home, in order to save energy.

Smart and efficient car charger

Shelly 3EM is developed to monitor one, two, or three phases and allows you to monitor the status and history and the current and past electrical power consumption of each separate channel for the day, week, month, or year. Shelly 3EM exports all data in CSV format in 10-minute intervals, making data analysis and cutting back costs easy. That way, you can monitor the exact energy your electric car consumes and calculate what part of your electricity bill it forms.

2-way energy consumption monitoring

Monitor your home, office, or factory, and avoid additional expenses or drops in voltage that can damage your appliances and devices. Shelly 3EM can calculate 2-way consumption: produced and used energy for each of the three phases. The device can be configured to measure three separate circuits of a mono-phase electrical system and control a contactor. View the quality of your electricity network regarding active power, reactive power, voltage, and power factor.

Full compatibility Shelly devices are compatible with Alexa, Google Home, Android and iOS. Together with the voice assistant, you can command Shelly devices using just your voice!
