Free water and space heating using excess energy from your PV.


This clever little piece of kit helps you to self-consume the green energy produced by your Solar PV system.

The Eddi device acts as an automatic power controller that diverts surplus power to a designated area – normally a hot water heater, to save energy and minimise your utility bills.

The Eddi system is fitted with a clear, graphical LCD display that will detail your saving information.

Eddi also comes with a 3 year warranty that covers labour too!  Add the My Energi Hub so you can use the My Energi app to monitor all your energy, boost your hot water or change any boost timers.  If you have multiple My Energi devices (perhaps a Zappi to charge your car) then you can monitor and control them all from one app.

Works as a stand alone product with size array to heat your immersion heater, storage heater, under floor heating, towel rail or electric radiator. All with surplus power from your solar panels .

But don’t worry, having this accessory installed won’t affect your Feed in Tariff.

Installation can take place at the same time that we come to install your Solar panels, or we can come back and retrofit it later. Any questions? Please get in touch.

How it works

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 and 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. eddi utilises myenergi’s proprietary VariSineTM technology to ensure compliance with worldwide power grid standards.
