The invention discloses an electric safety test method of a photovoltaic air conditioner. The electric safety test method of the photovoltaic air conditioner includes the steps that a draught fan, a compressor, a photovoltaic module and an alternating current module of the photovoltaic air conditioner are connected with a terminal integrator; an electric safety tester is connected with the terminal integrator; voltage is synchronously loaded at the input and output ends of a rectifying plate and the input and output ends of an inversion plate, and data of the electric safety tester is read. Byadopting the electric safety test method of the photovoltaic air conditioner, one-time wiring electrification is conducted to complete electric safety tests on the photovoltaic module and the alternating current module of the photovoltaic air conditioner, one-time electrification and electric safety tests on the compressor are completed at the same time, mainboard breakdown potential hazards caused by voltage differences are eliminated, the safe and efficient electric safety tests are achieved, control parameters are more accurate and rapider, the troubleshooting efficiency is high, the outgoing quality of the photovoltaic air conditioner is improved, wiring error hidden hazards brought by double-module single detection are solved, production operation is convenient and rapid to conduct,the universality is high, and after debugging, the electric safety test method of the photovoltaic air conditioner can be applied to rapid detection of the photovoltaic module and the alternating current module.
