80 liter photovoltaic hybrid boiler

The direct current from the photovoltaic modules allows you to produce inexpensive hot water directly, thus easily reducing your hot water costs.

The photovoltaic modules are simply plugged into the solar boiler. If you have more or less space, you can also increase or decrease the number of photovoltaic modules.

If you are connecting more than one photovoltaic module, you will need the 2-way, 3-way, or 4-way parallel connector. This allows for the easy parallel connection of multiple photovoltaic modules.

An extension cable bridges the distance between the photovoltaic modules and the solar boiler.

When the water in the solar boiler reaches its maximum temperature, the heating process ends automatically. If insufficient photovoltaic energy is available (e.g., in winter), the fothermo solar hybrid boiler conveniently heats the water using a standard electrical outlet.


For the 80-liter solar hybrid boiler, we recommend the following products:

- 1x fothermo 80 liter solar hybrid boiler
- 3x photovoltaic modules
- 1x 3-way parallel connector
- Extension cables of suitable length from the photovoltaic modules to the solar boiler
- suitable mounting system

The photovoltaic electricity is primarily used for hot water production. If the photovoltaic modules supply more energy than the solar boiler can convert into hot water, the excess energy is fed to another consumer (e.g., an 800 W micro PV inverter, a balcony power plant battery) via the fothermo switching device.

This way, almost all photovoltaic energy can be used. Hardly any energy is lost.

With the fothermo switching device, you can reduce not only your hot water costs but also your electricity costs by feeding excess electricity directly into your own home network and using it there.

Configure your own hot water supply with surplus feed-in. We recommend the following products:
- 1x fothermo 80 liter solar hybrid boiler
- 4x photovoltaic modules
- 4x extension cables (from the photovoltaic modules to the switching device)
- 1x extension cable (from the switching device to the boiler)
- 1x fothermo switching device
- 1x Micro PV Inverter / Balcony Power Plant Battery
