The utility model discloses a three-port photovoltaic inverter which comprises a first filtering module, a direct current output module, a direct current boosting module, a direct current-alternatingcurrent conversion module and a second filtering module, and the input end of the first filtering module is used for being connected with the photovoltaic module. The output end of the first filter isconnected with the direct current output module and the direct current boosting module, the output end of the direct current boosting module is connected with the direct current-alternating current conversion module, and the output end of the direct current-alternating current conversion module is connected with the second filter module; the output end of the second filtering module is used for being connected with an alternating-current power grid. In the embodiment of the utility model, the three-port photovoltaic inverter can simultaneously satisfy AC output and DC output, and 3V12V DC power supply is often needed
