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!
Features
- 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
- Wall mountable
- Please note* harvi doesn’t come with it’s own CT
