A photovoltaic inverter includes: an input unit to connected to a first terminal and a second terminal to which a positive (+) polarity or a negative (-) polarity of a photovoltaic module are connected; a switching device configured to control the first terminal and the second terminal connected to the input unit according to pre-set polarities of an inverter unit; a booster unit configured to boost a voltage of the photovoltaic module delivered form the input unit through the switching device; a capacitor configured to charge the voltage boosted by the booster unit; and an inverter unit configured to convert the voltage charged in the capacitor into an alternating current (AC) and provide the converted AC voltage for an electric power system. |
