Inventum Sunsmart Solar Water Heater

Turn your excess solar power into hot water. The Inventum Sunsmart solar water heater uses the excess electricity generated by your solar panels to heat your tap water—instead of selling that energy back to the grid for a pittance. This way, you can shower, bathe, and cook using your own green energy and reduce your gas consumption.

Converting Excess Solar Energy into Hot Water

If your solar panels generate more electricity than your home consumes, you’ll have a surplus. The myenergi eddi—the system’s brain—detects this immediately and directs that surplus directly to the water heater. This way, your own electricity is used to heat water—automatically and without you having to do a thing.

Modulating charging: make use of even a small surplus

The Sunsmart adjusts its charging power between 150 and 2,950 watts. When there’s a 500-watt surplus, it actually uses 500 watts—without drawing unnecessary power from the grid. A standard water heater runs at full power and draws the rest from the grid; the Sunsmart closely tracks your sunlight.

From 30% to 70–80% self-generated solar power

On average, a household uses about 30% of the solar energy it generates directly. With Sunsmart, that figure rises to 70–80%, because the electricity generated during the day is returned as hot water in the morning and evening. More self-consumption means a lower energy bill and less gas.

Benefits at a Glance

1. Use more of your own solar power instead of feeding it back into the grid.
2. Modulating charging, which means even small surpluses are fully utilized.
3. Start saving on your gas usage and CO₂ emissions right away.
4. Universal: Works with any brand of solar panels and inverter.
5. Installation is virtually plug-and-play, and it can be configured wirelessly via the app.

Which Sunsmart is right for your household?

The Sunsmart is available in 50, 80, 120, and 150-liter sizes, ranging from a small household to a family of 4 or more. Not sure which size is right for you? Use the Sunsmart calculator or ask for advice.

Ready for the end of the net metering program

Now that net metering is being phased out, feeding electricity back into the grid is becoming less and less profitable, while using the electricity yourself is actually becoming more valuable. The Sunsmart takes care of that for you: it lets you use your own solar power efficiently for hot water, without any complicated installation.

Frequently Asked Questions

What is a solar water heater?
A solar water heater uses the excess energy from your solar panels to heat tap water, rather than feeding that excess energy back into the grid.

Will the Sunsmart work with my solar panels?
Yes. The Sunsmart is a universal solution and works with all brands of solar panels and inverters.

Do I need a home battery?
No. The Sunsmart works independently with the eddi. When combined with a home battery, your self-consumption can increase even further.
