Description
The myenergi Harvi is a smart, wireless energy sensor that makes monitoring and managing your energy simple. Designed to work seamlessly with other myenergi products, Harvi removes the need for batteries or electrical wiring by harvesting its own power from the current it measures.
With three CT inputs, the Harvi can monitor up to three phases, making it suitable for both single-phase and three-phase installations. It accurately measures power flows in and out of your property, with a range of 25kW to 15kW (50Hz AC), so you can track import and export with ease.
Compact and discreet (H98 x W98 x D36mm), the Harvi is CE-certified and comes with a 3-year warranty for peace of mind. Please note: the Harvi does not include its own CT clamp — this must be purchased separately.
Whether you’re using it with a Zappi EV charger or other myenergi devices, the Harvi provides a simple, wireless solution for accurate energy monitoring without extra cabling or maintenance.
