One app to manage your energy lifestyle.

Efficiently monitor, control and optimise energy in your house: your PV system, battery, heat pump, EV charging and more, centrally managed in one app.

Everything in one app.

With Solarwatt, your solar panels, battery storage, EV charger, heat pumps, smart plugs, and more can all be managed, monitored and controlled in one app.

Everything from one supplier.

Since we offer a complete system from one manufacturer, we can offer complete peace of mind with one pack of warranty terms and local service in the UK & Ireland.

Everything working in harmony.

Instead of your battery, inverter, heat pump, and EV charger just coexisting, with Solarwatt, they talk to one another to work in the most cost-effective way possible around the clock.

At the heart of every SOLARWATT system is a SOLARWATT Manager. This little box communicates with devices on your local area network to manage how energy flows between them, then connects to the cloud to give you visibility and control over your complete system from the SOLARWATT Home app and our desktop SOLARWATT Manager portal.

Since we manufacture the hardware and engineer the software for each SOLARWATT Manager in Germany, we give you the peace of mind that your system is designed to meet the toughest European data governance standards.

Through the SOLARWATT Home app, you have complete control over your entire system, wherever you are. Our app, a recipient of the German Innovation Award 2026, has been smartly designed to make the complex topic of energy optimisation as simple as possible.

Once you've setup your electricity tariff in the app, we provide easy buttons to choose an optimisation mode, after which our intelligent machine-learning driven AI takes charge to manage energy flows throughout your house (such as by charging your battery on off-peak rates).

We call our complete system concept "sector coupling"—Here's what it can do.

Coordinated off-peak tariff charging for your battery & car charger.

Thermal energy management for your heat pump based on solar generation.

Running smart plugs on a schedule, and switching them on when the sun's shining.

Diverting surplus solar power to your immersion heater or car charger.

There's many different strategies for optimising energy usage to save money in your home - and the examples listed above aren't exclusively possible with a Solarwatt system. However, it's only through an integrated solution with hardware designed and tested to work with each other that all of these strategies be easily implemented in combination with each other, without requiring complex home networking or expensive building automation software.
