A solar array produces mostly during the day — often when no one is home. Automation's job: match your consumption to your production, automatically.
The principle of self-consumption
Electricity you consume directly is worth more than what you export. The aim is therefore to shift as many uses as possible into solar production hours, without thinking about it.
Driving big loads on the surplus
KNX can trigger flexible uses when the sun is producing: water heater, heat pump, car charging, even some appliances. The surplus feeds the home instead of going to the grid.
- —Water tank driven by production.
- —EV charging prioritised on solar surplus.
- —Flexible uses shifted to sunny hours.
Visualise to understand
Seeing your production, consumption and self-consumption in real time changes behaviour. KNX centralises this on a screen or app — energy becomes legible, and therefore controllable.
One brick of a coherent system
Solar PV reaches its full value integrated with the rest: heating, shading, charge point. The advantage of a single KNX base rather than devices that ignore each other. See our Energy & solar page.
