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

The Offgridtec 450W solar system with a 30-liter Fothermo hybrid water heater (MPN 018905) is the ideal solar kit for your hot water needs and can reduce your electricity costs by up to 100%. The photovoltaic water heater, with its high output of 550W, can replace your traditional electric water heater and provide hot water for your home.

Unlike the conventional Fothermo water heater, 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 design, 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 30-Liter Photovoltaic Hybrid Water Boiler

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