Description
ENERGY 3 (WI-MEF-3-200) is a 3-phase, bidirectional, 4-quadrant wireless energy consumption monitor designed for supervising photovoltaic installations, heat pumps, and measuring consumption in three-phase installations. The device records and visualises electrical network parameters (voltage, current, power, energy), collects average, minimum, and maximum values, and calculates energy consumption for different tariff plans. Communication occurs wirelessly via Wi-Fi using the F&F cloud, and access to measurement history is available through a mobile app or web browser.
The product is supplied by F&F Filipowski sp.k. – a Polish manufacturer of industrial and home automation devices. F&F offers a line of energy meters and monitors as well as control devices that integrate energy measurements with supervision systems.
