Off-grid capable hot water independent of the power grid and without registration of the photovoltaic system.

Warranty 3 years manufacturer warranty

Cost-saving hot water thanks to almost free photovoltaic power. Highly economical due to low initial investment costs and almost no running costs!

Plug and Play The photovoltaic modules are simply connected using MC4 connectors.

Environmentally friendly energy from the power of the sun! 100% renewable and sustainable! Save CO2 every day and actively contribute to climate protection.

Whether in your own home, garden or holiday home, warm water is now available everywhere with the help of solar energy. Simply install the boiler, connect it to a water supply and plug in the solar power supply, and you're done. From now on you will have warm water wherever you need it.

The water boilers are available in sizes 10 l, 30 l and 80 l. They are easily mounted on a wall. A pressure relief and non-return valve is also included in the delivery. The water connection is made to two 1/2 inch connections with external thread.

The photovoltaic off-grid boiler heats the water with up to 550 W. In order to have sufficient water available even on cloudy days, up to 2,000 Wp of photovoltaic power can be connected.

In the connection plan shown, 2 photovoltaic modules (optionally more or fewer possible) are simply connected to the photovoltaic off-grid boiler.

The heating process begins immediately after the photovoltaic modules are connected. Two or more photovoltaic modules are connected in parallel using photovoltaic parallel plugs . Anextension cable connects the photovoltaic modules to the boiler.

If the output of the photovoltaic modules exceeds the output of the boiler, the boiler regulates the maximum output of the modules down.

Since the entire system operates at protective extra-low voltage, no electrician is required for installation.

Excess photovoltaic power can optionally be easily fed into the home grid via a 600 W / 800 W Micro PV inverter using the fothermo switching device.

Install the photovoltaic off-grid boiler in front of your existing instantaneous water heater or heating system. The water in the boiler is preheated by the energy from the photovoltaic modules. This means that the water only needs to be heated a little or not at all via the instantaneous water heater.

Excess photovoltaic power can optionally be easily fed into the house grid via a 600 W / 800 W micro PV inverter with the help of the fothermo switching device .

The conventional electric boiler is often the largest consumer of electricity in the home. It normally requires around 3.5 kWh of electricity per day, which equates to around 1,277 kWh per year. With an average electricity price of €0.31/kWh, this results in annual costs of €396.02 for hot water production.

A photovoltaic boiler, on the other hand, primarily uses solar energy. For example, if three photovoltaic modules with 430 Wp each (1.29 kWp in total) are connected to a boiler, these modules generate around 1,200 kWh per year. A large part of this electricity can be used to heat water. On cloudy days, however, additional electricity must be drawn from the grid to heat the water. With a photovoltaic off-grid boiler, you can usually save around 75% of hot water costs, which corresponds to around €300 per year.

33mm Isolationsschaum: Alle Solar-Offgridboiler haben eine sehr gute thermische Isolierung. Bei erreichen der maximalen Wassertemperatur von 65 °C am Abend, verliert der 80 Liter Boiler bis zum nächsten Morgen nur etwa 7 °C.
