In a cogeneration system having a generator that generates DC power, an internal combustion engine for driving the generator, a battery that stores DC power for starting the engine, and an inverter that inverts the DC power generated by the generator to AC power, there are provided a solar unit that generates DC power by converting radiant energy of sunlight into electrical energy and a DC/DC converter that boosts the DC power stored in the battery, such that one of the generator and the solar unit is connected to the inverter through the DC/DC converter, thereby enabling to share the DC/DC converter and thus to make structure simple.
