摘要（英）：

The embodiment of the invention discloses a photovoltaic inverter and a photovoltaic inversion system. The photovoltaic inverter comprises an inversion unit and at least two disconnecting switches. The input end of the inversion unit is electrically connected with the DC output end of a solar cell module, and is used for receiving direct current outputted by the solar cell module. The inversion unit is used for converting direct current into alternating current. The output end of the inversion unit is electrically connected with at least two disconnecting switches, and the disconnecting switches are respectively used for outputting different AC voltages to a boosting transformer. According to the invention, reasonable configuration of the photovoltaic inverter is facilitated, the construction cost of a photovoltaic power station is reduced, and the utilization rate of the photovoltaic inverter is improved.
