A power generating system (1) comprises a power generator (2) generating DC power, and an inverter circuit (3) for converting DC power into AC power; the power generator (2) comprises a plurality of power generating modules (21-28) each comprising a plurality of power generating units (30) and at least one electric storage means connected to each of the plurality of power generating modules (21-28). A plurality of first switch means (S11a-17a) connect/disconnect each of the positive electrodes (62) of the plurality of power generating modules (22-28) to/from a positive bus (6), a plurality of second switch means (S11b-17b) connect/disconnect each of the positive electrodes (62) of the plurality of power generating modules (22-28) to/from the negative electrodes (60) of the power generating modules (21-27) contiguous to the one side, a plurality of third switch means (S1-S7) connect/disconnect each of the negative electrodes (60) of the plurality of power generating modules (21-27) to/from a negative bus (7), and the DC output voltage can be increased/decreased stepwise by switching the switch means (S1-S7,S11a-17a,S11b-S17b). |
