The preset environment temperature-preset starting voltage value preset table may be obtained by multiple tests performed by a developer and preset in the first controller 121, after receiving the power starting signal, the first controller 121 determines the current environment temperature and selects a preset starting voltage value according to the current environment temperature, for example, "the environment temperature is 30 degrees below zero, the preset starting voltage value is AC180V, the environment temperature is 30 degrees above zero, the preset starting voltage value is AC160V", and the first charging branch 122 is controlled to output an alternating current with the voltage value of the preset starting voltage value according to the content of the embodiment described above. Therefore, in practical application, the preset starting voltage value can be dynamically adjusted according to the ambient temperature, so that the outdoor power supply device is ensured not to enter an overload protection state when being just started under any environment, and the working reliability and stability of the outdoor power supply device are effectively ensured.
