A power-saving effect displaying unit includes a power-consumption computing unit that calculates power consumption based on a voltage obtained by an output-voltage computing unit and a current obtained by a current detecting unit. A power-saving-effect generating unit acquires a power-saving effect based on the power consumption. A display displays an instantaneous power-saving effect and an integration value of the power-saving effect under operation with the inverter, with respect to commercial operation, based on the instantaneous power consumption under the operation with the inverter calculated by the power-consumption computing unit, and on electric characteristic data obtained by comparing with the power consumption under the commercial operation.
