[0002] When an inverter for a diesel power station enters the factory for inspection, due to the lack of equipment and measures to check its working condition, only the appearance quality is inspected. If the appearance quality is qualified, the product is put into storage. This inverter is used as a qualified product for assembly and wiring in the diesel power station.

[0003] When the diesel power station is not started and running, it is generally impossible to effectively detect the functions of the inverter. These functions are operated and displayed on the electrical control panel. In this case, it is necessary to wait until the product assembly and the electrical system wiring are completed and then transfer to the test station to start and run the diesel power station for testing.

[0004] During the process of starting and running the diesel power station in the test station, if there is no voltage output and the working condition of the indicator lights on the control panel, it is necessary to search for the reasons from many places.
