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

The Offgridtec 900W solar system with 80L Fothermo hybrid boiler (MPN 018910) is the ideal solar set for your hot water supply 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 sustainable hot water in your home.

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

1500W reheating

The Fothermo Hybrid Boiler offers a smart solution for when solar energy is insufficient. With adjustable reheating via 230 V, a minimum temperature, e.g., 35°C, can be set. If the temperature falls below this, the boiler automatically reheats with 1,500 W from the mains until the minimum temperature is reached. The maximum water temperature is 65°C, enough for around 180 liters of hot water with an 80-liter boiler.
