In a cogeneration system having at least with a generation unit comprising a generator connectable to an AC power feed line between a commercial power network and an electrical load, an internal combustion engine for driving the generator, and a battery, the cogeneration system producing hot air/water through exchange he at generated by the engine to supply to a thermal load, it is determined whethe r it is a predetermined self-diagnosis time, and when the result is affirmative, the generation unit is operated by an output of the battery and self-diagnoses is made on a t least one of output voltage of the battery, a speed of the engine and an output of the generator, when it is determined to be the predetermined self-diagnosis time. |
