Description

The Myenergi Eddi 2.1 (EDDI-16A1P02H) Solar/Wind Energy Diverter is an intelligent, eco-smart energy management unit that stops your excess solar or wind energy going to waste and uses it to heat your home. Ideal for households with solar PV panels or wind generation systems, this advanced diverter ensures that surplus energy is not exported back to the grid, but instead redirected to power your heating appliances, helping you reduce energy bills and improve overall efficiency.

At the heart of the Eddi 2.1 is Myenergi’s innovative VariSine™ technology, which optimises the way excess electricity is delivered to your appliances while maintaining full compliance with global power grid standards. Whether you're heating water via an immersion heater or supporting other compatible systems, the Eddi intelligently diverts energy where it’s needed most. It can even manage two heating devices sequentially, ensuring maximum utilisation of available renewable power.

This model also supports integration with heat pumps (when used with the optional Relay and Sensor Board) and works alongside battery storage systems, making it a versatile addition to modern renewable energy setups. Its fan-less cooling design ensures silent operation, while the graphical back-lit LCD screen provides clear, user-friendly access to system data and settings.

The Eddi 2.1 is fully internet-connected, featuring built-in Wi-Fi and an Ethernet port for seamless integration into your smart home ecosystem. Through the dedicated myenergi app, users can monitor energy usage in real time and control the system remotely, offering complete visibility and control from anywhere.

What's In The Box: 1x Eddi unit with mounting bracket attached, 1x Current transformer with 5m cable (Grid CT sensor), 2x Antenna, 4x Screws (for use on cable clamps) & 1x User manual.
