switching device

The fothermo switching device is the solution for using excess electricity from the boiler or heating element in your own home network. Especially in the summer months, it often happens that the photovoltaic boiler is already completely heated up in the morning hours.

If the photovoltaic output is already high in the morning, the switching device assumes that the boiler will be fully heated up during the day. Therefore, the switching device switches individual PV modules to the connected micro PV inverter in the morning, so that electricity is fed into the house network throughout the day. This largely covers the basic load of the house.

As soon as the boiler has completely heated up, all connected photovoltaic modules are switched to the micro PV inverter.

The switching device always prioritizes the photovoltaic boiler before surpluses are fed into the house network, thus ensuring maximum efficiency of the entire photovoltaic system.
