Power generator system

A power generator system comprising:

• an inverter-type first generator and an inverter-type second generator mutually connected in parallel and mutually operated synchronously, the first generator and the second generator including an engine and being driven by the engine respectively;
• a remaining fuel detector configured to detect a remaining fuel amount of each of the first generator and the second generator;
• an operable time calculator configured to calculate a remaining operable time of the each of the first generator and the second generator based on the remaining fuel amount detected by the remaining fuel detector;
• and
• a power adjuster configured to adjust a power of each of the first generator and the second generator so as to equalize the remaining operable time of the first generator and the remaining operable time of the second generator calculated by the operable time calculator while keeping a total power of the first generator and the second generator constant.
