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
No batteries or electrical wiring required
CT inputs: 3 inputs enable 3-phase
Measurement range: 25kW to 15kW (50Hz AC, import and export)
Please note harvi doesn't come with its own CT
