If a hairdryer, radiant heater and stove are running at the same time, not only the user but also the generator of the domestic solar system can get too hot. This is caused by what is known as phase shift load - it occurs when the power consumption is not evenly distributed across all three phases of the alternator. The development by Julian Reitz from Grünberg in Hesse prevents this with a process that automatically compensates for unbalanced loads. His system could increase the service life and efficiency of solar systems in decentralized energy supply.
