450W solar system with 30L Fothermo hybrid boiler for hot water production

The Offgridtec 450W solar system with a 30L Fothermo hybrid boiler (MPN 018905) 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.

• 1x Luxen Solar 450W Bifacial Solar Module TopCon Luxneri Series N5 Full Black
• 1x Fothermo Hybrid Photovoltaic Boiler 30 liters
• 2x Offgridtec 10m 6mm² MC-4 connection cable plug/socket extension

Fothermo Photovoltaic Hybrid Water Boiler 30 Liters

The Fothermo 30L hybrid water boiler uses cost-effective solar power to generate hot water and features a digital temperature display. The hybrid version allows for supplementary heating via the electrical grid. Thanks to the plug-and-play system, no licensed electrician is required for installation.

The hybrid boiler offers a smart solution for when solar energy is insufficient. With adjustable 230 V supplementary heating, a minimum temperature—e.g., 35°C—can be set. If the temperature drops below this level, the boiler automatically supplements heating with 1,500 W from the grid until the minimum temperature is reached. The maximum water temperature is 65°C, enough for about 72 liters of hot water in the 30-liter boiler.
