    • A control unit repeats the series of processing of comparing a first phase representing a phase of the first reference sine wave and being a phase included in the first synchronization signal, with a second phase that is the phase of the second reference sine wave when the first synchronization signal is received when the communication unit receives the first synchronization signal from the other inverter generator, changing a phase change amount per unit time of the second reference sine wave in accordance with the comparison result, continuing to update the phase of the second reference sine wave so that the phase of the second reference sine wave changes with a phase change amount per unit time after the change with reference to the first phase until the next first synchronizing signal is received from the other inverter generator. The control unit compares a third phase that is a phase included in the first synchronization signal received prior to the polarity reversal timing of the second reference sine wave by the communication unit and that is one of the first phases, with a fourth phase that is a phase of the second reference sine wave when the first synchronizing signal is received, changing the phase change amount per unit time of the second reference sine wave in accordance with the comparison result, and predicts the polarity inversion timing of the first reference sine wave by continuing updating the phase of the second reference sine wave so that the phase of the second reference sine wave changes with a phase change amount per unit time after the change.
