PIONIERKRAFT's innovative technology makes it possible to share renewable energy within an apartment building with up to six residential units. The tenant as the system operator has no supplier obligations and the supplied tenants retain their energy suppliers, whereby the solar power is supplied preferentially, simply and profitably from the first party supplied. The PIONIERKRAFTwerk determines the currently available power at the operator (prosumer) and the energy requirements of the connected party (consumer) and intelligently controls the energy distribution. The device is connected via the Internet to the platform provided by PIONIERKRAFT, where the amount of electricity supplied, billing data and CO2 savings can be viewed at any time.
