myenergi harvi (HARVI-65A3PR): Battery-Free Wireless Energy Sensor

Revolutionise your myenergi installation with the harvi energy harvesting wireless sensor. This clever device eliminates the need for unsightly and often difficult-to-install wired sensor cables running from your main fuse box or generation meter back to your eddi power diverter or zappi EV charger. It allows these devices to accurately measure grid import/export or solar/wind generation for optimal performance.

Wireless Transmission Powered by Energy Harvesting

The magic of harvi lies in its energy harvesting technology. As described by myenergi, it draws its operating power directly from the magnetic field around the cable being monitored by the connected CT (Current Transformer) clamp(s). This means no batteries are required, and no separate power supply needs to be wired in, making for a cleaner, simpler, and more reliable installation.

Simplified Installation, Enhanced Flexibility

Running CT clamp wires can be one of the most challenging parts of installing energy monitoring or diversion systems. harvi completely removes this headache. Simply connect your CT clamp(s) to the harvi unit near the meter or circuit you need to monitor, and it will wirelessly transmit the readings back to your paired myenergi device (like the eddi or zappi). This HARVI-65A3PR model typically includes three 65A CT clamps, suitable for monitoring three-phase supplies up to 65A per phase, or for monitoring multiple single-phase circuits (e.g., grid and solar PV generation).

Seamless Integration with myenergi Ecosystem

harvi is designed as an integral part of the myenergi ecosystem. It pairs easily with eddi and zappi devices, providing them with the essential grid and/or generation data they need to perform functions like dynamic load balancing, solar EV charging, and surplus energy diversion accurately. Using harvi ensures these devices operate at peak efficiency, maximising your self-consumption of renewable energy.
