The fothermo switching device is an innovative solution for using excess electricity produced by your solar water heater in your own home network. Especially in the summer months, it is common for the photovoltaic boiler to be fully heated already in the morning.
The switching device anticipates the full load of your boiler during the day by switching the photovoltaic modules to the connected photovoltaic microinverter each morning. This allows electricity to be injected into your home network throughout the day, largely covering the base load of the house.
The switching device always gives priority to the photovoltaic boiler, ensuring maximum efficiency of your photovoltaic installation as a whole.
The switch device can be mounted on the wall using four screws. Photovoltaic modules or electrical consumers are connected via screw terminals directly to the switching device or via the supplied photovoltaic connectors. Installation is simple and intuitive, with clear instructions to ensure correct polarity of connections.
