myenergi - Harvi Energy Harvesting Wireless Sensor


About harvi

 harvi is a clever little device that enables the zappi and eddi products to be installed without using a wired current transformer (CT) for measuring the grid and or generation power; instead the CT is connected to harvi. No power source is needed for harvi – the energy from the CT is harvested and used to transmit the measurement signal to the zappi or eddi. This means batteries or electrical wiring are eliminated!


    • Wireless power sensor
    • Energy harvesting – no batteries or electrical wiring


    • Uses standard CTs supplied with eddi & zappi


    • 3 CT inputs for 3-phase supplies
    • Grid / Generation / Storage measurement configurable
    • Fast & accurate measurement
    • Wall mountable
    • Please note* harvi doesn’t come with it’s own CT
