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

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

Unlike the conventional Fothermo boiler, the hybrid version offers the option of reheating via the 230V power grid. This ensures a continuous hot water supply, regardless of weather conditions or sunlight. The kit includes all the accessories needed to provide hot water at the sink, in the shower, or in the kitchen. Thanks to the plug-and-play principle, you can install and mount the solar module yourself in just a few simple steps

1500W auxiliary heating

The Fothermo Hybrid Boiler offers a smart solution for when solar energy is insufficient. With an adjustable backup heater powered by 230 V, a minimum temperature—e.g., 35°C—can be set. If the temperature drops below this level, the boiler automatically activates the 1,500 W backup heater until the minimum temperature is reached. The maximum water temperature is 65°C, enough for about 180 liters of hot water in the 80-liter boiler.
