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 required

  • Uses standard CTs supplied with eddi & zappi products

  • 3 CT inputs for 3-phase supplies

  • Grid / Generation / Storage measurement configurable

  • Fast & accurate measurement
