The Eddi device by Myenergi is a Solar power diverter for free water and space heating using excess energy from your PV or wind turbine. The small but state of the art device is used with grid-tied PV or wind turbine systems. Excess energy from the micro-generation system is used to heat water or rooms rather than exporting it to the grid.
The Eddi Device works by a grid current sensor simply clipping around the incoming supply cable. This sensor is then used to monitor excess power and the Eddi will automatically alter the voltage to the heater load, thus consuming the surplus power.
This small sensor device is able to harvest energy wireless and is an essential part of the installation process if you want to save time and money.
It has many great qualities including the elimination of unsightly wiring around the home and avoids the need to lift up floorboards or disturb home decor.
The Harvi enables the Zappi and Eddi products to be installed without using a wired current transformer for measuring the grid and or generation power, in its place the current transformer is connected to Harvi, meaning no power source is needed for Harvi.
