860W solar system with 80L Fothermo hybrid boiler for hot water preparation

The Offgridtec 860W solar system with an 80L Fothermo hybrid boiler (MPN 018910) is the ideal solar set for your hot water supply and can reduce your electricity costs for it by up to 100%. The photovoltaic boiler, with a high output of 550W, can replace your conventional electric boiler and provides sustainable hot water for your home.

Unlike the traditional 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 solar radiation. The set includes all the accessories needed for providing hot water in the sink, under the shower, or in the kitchen. Thanks to the plug-and-play principle, the installation and mounting of the solar module can be easily done yourself in just a few steps.

1500W Reheating

The Fothermo hybrid boiler provides a clever solution in case solar energy is insufficient. With an adjustable reheating feature via 230 V, a minimum temperature, e.g., 35°C, can be set. If the temperature drops below this level, the boiler automatically reheats with 1,500 W from the grid until the minimum temperature is reached. The maximum water temperature is 65°C, sufficient for approximately 180 liters of hot water with the 80-liter boiler.

The Bifacial Luxen Solar 430W Full Black Solar Module

The monocrystalline and bifacial 430W Full Black solar module of the N5 series from Luxen Solar (MPN LNVB-430ND) impresses with a combination of various technologies, such as N-TOPCon cell technology and a 108 half-cell layout. For performance enhancement, the SMBB half-cut cell technology was also applied during production. This state-of-the-art solar module represents the pinnacle of solar technology, offering impressive output and low levelized cost of electricity.
