    Solar heating rod and smart controller for water boilers – Resistencia solar y controlador inteligente para calderas de agua"

    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.

    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.
