Shelly Pro 3EM Power Meter
Shelly Pro 3EM 120A Power Meter
The Shelly Pro 3EM is a next-generation 3-phase power consumption meter that enables precise monitoring of electricity usage in households, businesses, and industrial facilities. With an accuracy of 1%, it monitors the consumption of devices, circuits, and office equipment in real-time. The device features Wi-Fi, Bluetooth, and LAN connectivity and stores historical data for up to 60 days. Thanks to its advanced scripting functionality, custom scenarios for energy management can be created.
Additionally, the Shelly Pro 3EM can be synchronized with the Zendure Hyper 2000, allowing the AC output power of the Hyper 2000 to be automatically adjusted to energy consumption. This ensures efficient energy use and optimal energy management.
