eddi energy redirector for solar surplus

myenergi eddi energy redirector — free hot water from your excess solar energy

The eddi is a smart energy redirector that sends your excess solar power to your water heater or heating system instead of selling it back to the grid for next to nothing. That way, you can heat your water with your own green energy—using the water heater you already have.

What does an energy distributor do?

If your solar panels generate more power than your home is currently using, a surplus is created. Instead of feeding that surplus back into the grid, the eddi directs it to a heating element. Every kilowatt-hour that goes to your water heater is one you don’t have to purchase at a high cost from the grid.

Works with your existing water heater and heating system

You don't need a special water heater. The eddi works with any resistive heating element: an electric water heater, a convection heater, electric floor heating, or a pool heater. It's ideal if you want to make your current system smart without replacing everything.

Are you looking for a complete, ready-to-use water heater? Then check out the Sunsmart solar water heater, which already comes with eddi technology built in.

Precise Redirection with VariSine™ Technology

The eddi continuously measures your import and export via CT sensors and adjusts the power to your water heater with an accuracy of 0.1%. This way, it uses your surplus precisely, staying well within grid standards—no more and no less.

Always Have Hot Water with Boost and Schedules

No sun right now, but still need hot water? With Manual Boost, you can temporarily heat water at full power. Use the Boost Timer to set specific times, such as in the morning during off-peak hours. That way, you’ll always have hot water when you need it.

Single-phase or 3-phase: eddi and eddi+

The eddi (single-phase) delivers up to 3 kW to your heating element. Do you have a three-phase connection or a larger water heater capacity? Then the eddi+ delivers up to 9 kW, so you can heat up faster.

Benefits of the eddi

1. Convert excess solar energy into hot water for free.
2. Works with your existing water heater or heating system—no need for a new water heater.
3. Controls power with an accuracy of 0.1% using VariSine™.
4. Always have hot water thanks to Boost and customizable schedules.
5. Part of the myenergi ecosystem: combine with zappi, libbi, and harvi.

Ready for the end of the net metering program

Now that net metering is being phased out, selling excess electricity back to the grid is becoming less and less profitable. Using your surplus electricity yourself, on the other hand, is becoming more valuable. The eddi extracts that value from your water heater instead of from your energy contract.

Frequently Asked Questions

Which water heater is compatible with the eddi?
Any resistive heating element: an electric water heater, convection heater, electric floor heating, or pool heater.

Can the eddi control my boiler?
Not directly. However, using a relay, the eddi can signal when there is excess energy, for example, for a heat pump.

Can I use the eddi with a home battery?
Yes. When used with a libbi, you can set priorities in the app—for example, charge the battery first and then send any remaining surplus to the water heater.
