Generator apparatus for a combined heat and power system, method for operating a generator apparatus and combined heat and power system

The invention relates to a generator apparatus (100) for a combined heat and power system, a combined heat and power system and a method for operating a generator apparatus (100) of a combined heat and power system. It is the object of the invention to provide a generator apparatus (100) for a combined heat and power system, a combined heat and power system and a method for operating a generator apparatus (100) of a combined heat and power system in which an optimal and efficient operating mode is ensured even under varying ambient conditions. The generator apparatus is characterised in that a converter device (10) is connected between the generator and the regulating device (2) in order to efficiently operate the generator apparatus (100) at different powers.
