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!

Key Features:

• Wireless Power Sensor
• Energy harvesting - No batteries or electrical wiring required
• Fast and accurate
• Wall mountable
• Uses CT supplied with Eddi and Zappi products
• 3 CT inputs for 3-phase suppliers
• Grid/ Generation/ Storage measurement
