Abstract: In a power conversion system, a first control unit acquires monitor data from a first power storage unit, notifies a second control unit of a remaining capacity of the first power storage unit, and sets an output voltage of a first DC-AC conversion unit. The second control unit controls an output current of a second DC-AC conversion unit to bring the remaining capacity of the first power storage unit and a remaining capacity of the second power storage unit closer to each other on the basis of a total current supplied to a load, the remaining capacity of the first power storage unit, and the remaining capacity of the second power storage unit.
