Munich based start-up Pionierkraft has worked with Infineon Technologies on a hardware and service that enables self-produced solar energy to be distributed on-demand between different households.
PIONIERKRAFTwerk allows energy to be shared in a decentralised manner and without intermediate storage. The bi-directional hardware is connected to the Pionierkraft platform via the Internet and determines the power surplus of the generator as well as the current demand of neighbours to autonomously control the distribution process. This allows households without a photovoltaic system can use solar power. The solution also regulates the power flows without using the public grid.
Several Infineon components are used in the system, including the discrete CoolSiC MOSFET IMBG120R030M1H in the surface-mount D2PAK-7L package and the EiceDRIVER Compact Gate Driver 1ED3122MU12H. This supports bi-directional power up to 2kW between households. In addition, the CoolMOS P7 power MOSFET IPD70R1K4P7S ensures the safe and reliable operation of the system.
Infineon sees around 28 million multi-family houses with over 80 million households must be equipped with photovoltaics. Despite the support of the EU, there are still enormous technical and regulatory obstacles, specifically with the power supply for small multi-family houses from renewable energy sources.
