[0041] In the embodiment of the present application, in the detection configuration interface of the detection user corresponding to the client, multiple option boxes corresponding to the photovoltaic inverters of the detection user are displayed, and the detection user can select one or more photovoltaic inverters to be detected from all photovoltaic inverters by checking; the photovoltaic inverter to be detected is the photovoltaic inverter that needs to be detected. In response to the photovoltaic inverter to be detected selected by the detection user in the detection configuration interface, at least one detection unit corresponding to each photovoltaic inverter to be detected is displayed in the detection configuration interface by means of a drop-down box or an option box, etc.; so that the detection user selects one or more target detection units in all corresponding detection units for each photovoltaic inverter to be detected, and the target detection unit refers to the detection item that needs to be detected. After the detection user selects the target detection unit for each photovoltaic inverter to be detected, the detection configuration field corresponding to each target detection unit of each photovoltaic inverter to be detected is displayed in the detection configuration interface, so that the detection user inputs at least one input parameter (each input parameter includes an input current and an input voltage) and a determination threshold parameter (the maximum value of the determination threshold range or the determination threshold range) under each target detection unit of each photovoltaic inverter to be detected for the detection configuration field.

In addition to the above equipment, it can also include thermocouples for temperature detection and USB devices for USB detection (when detecting, it is connected to the USB interface of the photovoltaic inverter to be detected).

[0045] In addition, before responding to the input parameters and judgment parameters configured by the detection user in the parameter configuration interface for the photovoltaic inverter to be detected under the target detection unit, the method also includes: in response to the communication parameters of the external detection device that communicates with the photovoltaic inverter to be detected and corresponds to the detection type to which the target detection unit belongs, configured by the detection user in the communication configuration interface, establishing a communication connection between the photovoltaic inverter to be detected and the external detection device according to the communication parameters.

[0055] Specifically, if the judgment threshold parameter is within the judgment threshold range, the difference between the actual input parameter and the actual output parameter is numerically compared with the judgment threshold parameter to obtain the detection result of the photovoltaic inverter to be detected for the input parameter under the target detection unit, including: if the absolute value of the difference is within the judgment threshold range, the detection result of the photovoltaic inverter to be detected for the input parameter under the target detection unit is detection passed.

If it is non-load calibration, high-power calibration and low-power calibration, the power supply device supplies power to the photovoltaic inverter to be detected according to the corresponding input parameters; after the photovoltaic inverter to be detected is running stably, the detection value of the parameter detection device is read to obtain the actual input parameters and actual output parameters of the photovoltaic inverter to be detected under the target detection unit for the corresponding input parameters; and the difference between the actual input parameters and the actual output parameters is numerically compared with the judgment threshold parameter to obtain the detection result of the photovoltaic inverter to be detected under the target detection unit for the corresponding input parameters.
