ÖkoFEN presents fully self-sufficient family home


Independence in terms of energy supply is one of the most important future topics. For this reason, ÖkoFEN presents a new, and as the company says unique system at the ISH expo in Frankfurt. The system allows single-family houses to be independent of power supply.

In addition to pellet boilers that can be retrofitted with a Stirling engine for electricity generation, ÖkoFEN developed a system that also integrates a battery and a photovoltaic system to ensure maximum energy independence. The electricity generating pellet boiler powers itself and delivers up to 600 W of electrical power which can be used directly or stored for other electricity consuming devices. All components of this system such as PV with inverter, battery and boiler with integrated Stirling engine are linked with online weather data and are processed and visualized in the ÖkoFEN controller.

The photovoltaic system is producing solar electricity if the sun is shining. In the morning, the evening and in times without sun the Stirling engine of the wood pellet boiler is producing electricity. The electricity is supplied directly for the house, if needed, if not, all the energy is saved in the battery.

In the event of a blackout, the system is able to start autonomous and is powered by the electricity of the photovoltaic system, the Stirling engine and the buffer function of the battery without the grid. The whole energy system operates self-sufficient.

ÖkoFEN says that the modular design allows consumers to switch step by step to 100% ecological heat and 100% self-generated electricity. The combinable modules are a wood pellet boiler with an e-ready package, a photovoltaic system, battery and as a last step to self-sufficiency the power generation for the wood pellet boiler.

TESVOLT has been allocated the contract to build the worldwide largest off-grid-battery-system to deal with the energy loss in much needed water pumps in Rwanda. For the dedication and innovative mindset to promote the mission of clean energy while supporting agricultural projects TESVOLT is the perfect candidate for the Global Leading RES Seal.

The commercial storage system manufacturer TESVOLT has supplied a battery storage system for the Coburger Hütte mountain refuge owned by the German Alpine Club (DAV) in Tyrol, Austria. The storage system, with a capacity of 77 kWh, replaces the old lead-acid battery and increases the solar power consumption of the cabin, which is fitted with a 16 kWp solar power system. The entire energy supply installation is tailored to meet the DAV’s stringent environmental and sustainability criteria for mountain regions, and will reduce the consumption of rapeseed oil as fuel.

Siemens Gamesa Renewable Energy has been commissioned to build a pioneering wind complex in Australia, which will combine the installation of a wind farm with 56 of the firm's SG 3.4-132 turbines with a battery energy storage system. Under the terms of the contract entered into with the renewable energy IPP, Neoen, Siemens Gamesa will build the entire complex on an EPC basis and then maintain it for 25 years.

The Schletter-Group installed the biggest carport photovoltaic system in Germany at the airport Weeze in Westphalia. For the innovative design and the unique location the German CleanTech Institute is honoring Schletter with the Global Leading RES Seal – Unique Location. In only six weeks of time 70 skilled workers installed the Schletter carport system Park@Sol on 25,000 square meters. Because of the special build as a modular system the solar panels could be adapted to the local site conditions. And the airport management is already thinking about the next project, a charging station for electric cars.
