with solar power detection
Shelly 3EM shows separately the consumption history for all 3 phases,
including energy produced from solar panels and returned to the grid.
365 DAY EMBEDDED HISTORY
Shelly3EM export all data in CSV format in 5 minute intervals.
Stored in device data can help for analytics and detailed statics.
All data is stored in the cloud at incrementing intervals
Professional 3-phaseenergy meter
• Real-time and history information about efficiency of the solar or wind energy system and how much energy has been produced.
• Shelly 3EM can be configured to measure three separate points of a monophase electrical system and measure each of them separately.
• Shelly 3EM may calculate 2-way consumption: produced and used energy for each of the three phases.
Shelly 3ЕМ comes with a programming/debug header which can be used for flashing alternative firmware to the device.
It has ESP8266 inside, with a 4MB flash. A USB-to-UART adapter is needed as well as a reliable 3.3V power supply with at least 350 mA drive capability.
