900W solar system with 80L Fothermo hybrid boiler for hot water preparation

The Offgridtec 900W solar system with an 80L Fothermo hybrid boiler (MPN 018910) is the ideal solar set for your hot water supply and can reduce your energy costs for this purpose by up to 100%. The photovoltaic boiler, with its high output of 550W, can replace your traditional electric boiler and provides sustainable hot water at home. 

In contrast to the conventional Fothermo boiler, the hybrid version offers the possibility of reheating via the 230V power supply. This ensures continuous hot water supply, regardless of weather conditions or sunlight. The set includes all accessories for providing hot water at the sink, in the shower, or in the kitchen. Thanks to the plug-and-play principle, the installation and mounting of the solar module can be done easily with just a few steps.

1500W Reheating

The Fothermo Hybrid Boiler offers a clever solution for situations where solar energy is insufficient. With an adjustable reheating feature via 230V, a minimum temperature (e.g., 35°C) can be set. If the temperature falls below this, the boiler automatically reheats with 1,500W from the grid until the minimum temperature is reached. The maximum water temperature is 65°C, sufficient for approximately 180 liters of warm water with the 80-liter boiler.
