Solar boiler

Energy controller

Your smart solar brain

The controller keeps your water hot by automatically switching between solar energy and the grid, all based on your setup and preferences.

Solar-first setting
Set how much solar power is required before the system switches to the grid.

That way, you always use as much solar energy as possible, while never running out of hot water.

Personalized heating plan
Choose when and how often the system reheats.

For example, only in the evening or multiple times a day.

With 1 heating rod

Flexible and smart

• One hybrid rod heats the water from the bottom of the tank.
  

Flexible
The hybrid rod can be powered by solar energy or the electrical grid, giving you full flexibility and hot water security, even on cloudy days.

Smart
If there's not enough solar energy, the system uses electricity from the grid as a backup.

You can customize when and how it kicks in, based on your preferred temperature, available solar power, and daily routine.

Ideal for smaller tanks like 80l or 120l.

With 2 heating rods

Fast and efficient

• One hybrid rod heats the water from the top of the tank.
• One solar-only rod heats the water from the bottom. 

Fast
The hybrid rod heats the top of the tank first, so you get hot water faster, even if the full tank isn't heated yet.

Efficient
At the same time, the bottom part stays cooler longer, so your system can keep absorbing solar energy throughout the day.

Ideal for larger tanks like 200l or 300l.
