free water and space heating using excess energy from your PV or wind turbine

eddi is an energy management system for use with grid-tied PV or wind turbine systems. Excess energy from the microgeneration system is used to heat water or rooms rather than exporting it to the grid. Two heaters are supported (typically top and bottom immersion heaters).

A grid current sensor (supplied) simply clips around the incoming supply cable. This sensor is used to monitor excess power and eddi automatically adjusts the voltage to the heater load, thereby consuming the surplus power. A self-powered wireless sensor is available separately.

An internal expansion interface provides a means to add an expansion module to enable various functions such as auto-switching from day-time and night-time supply, heat pump interfacing for legionella control and temperature sensing. An optional ELS module allows eddi to be officially used for G100 compliant Export Limiting Schemes, avoiding expensive grid network reinforcement costs.

eddi utilises myenergi’s proprietary VariSine^TM technology to ensure compliance with worldwide power grid standards.
