Technologically, inverters are the most important components of PV systems. They determine the efficiency and reliability of the entire system. To further strengthen the international competitiveness of the German photovoltaic industry, the technology used in inverters must be continuously improved while innovations in a wide range of relevant areas are also needed to reinforce the technological advantage the industry currently enjoys.
Today, mechanical and electromechanical components for connecting, supporting and cooling make up 70% of a PV inverter. The partners in the PV Pack project want to develop totally new approaches in optimization of advanced packaging and cooling technologies. These innovative solutions will be used in a three-phase inverter to achieve a new, highly integrated system concept and then tested in real-world conditions. The results of the project will lead to significantly more compact PV inverters, which in turn will reduce costs, thus meeting the future demands of solar power use.
The mission of the project is to develop future-proof technologies that enable more effective manufacturing of highly reliable and durable inverters in the 10-kW to 40-kW power range, thus contributing toward improving the competitiveness of photovoltaics and in strengthening Germany as a country of development and production.
