Power generator system

A power generator system comprising a first generator and a second generator mutually connected in parallel, the first generator and the second generator including engines and inverter circuits and being driven by the engines, respectively,

• the power generator system comprising:
• a detector configured to detect any of a power, a remaining fuel and a noise of the first generator, or to detect a physical quantity correlated any of the power, the remaining fuel and the noise of the first generator;
• a determinator configured to determine whether a parallel operation of the first generator and the second generator is necessary based on a detection value detected by the detector when the first generator is operating and the second generator remains unstarted;
• a power supply unit configured to supply a starting power to the second generator to start the second generator when it is determined by the determinator that the parallel operation is necessary;
• and
• a generator controller configured to control the second generator so as to operate synchronously in parallel with the first generator after the second generator is started, wherein
• the detector includes a remaining fuel detector configured to detect a remaining fuel of the first generator, and
• the determinator determines that the parallel operation is necessary when the remaining fuel detected by the remaining fuel detector becomes equal to or less than a predetermined value.
