The Zappi is Myenergi’s smart EV charger, with which you can charge your car when and how you want.

As with all of their products, it’s designed to work seamlessly with solar PV, or any other form of microgeneration, and battery storage. It monitors exported power from the property and, in ECO mode, controls the charging rate of the EV to match the available surplus generation. This means that you can charge your car for free!

Zappi chargers can be installed under the OLEV grant scheme where an accredited installer is used.

The Myenergi product family isn’t limited to EV: the Eddi power diverter directs your surplus energy generated by wind or solar to heat your water or rooms. Also acting as an export limitation device, the Eddi is a great addition to any system to maximise use of your home renewables.


Myenergi's Eddi diverts surplus power from your solar or wind turbine system – putting it to use to heat your water or rooms rather than exporting it to the grid.

Eddi is an energy management system for use with grid-tied PV or wind turbine systems. Excess energy from the microgenertation 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. Harvi, 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.

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 VariSineTM technology to ensure compliance with worldwide power grid standards.
