[0066] In one embodiment of the present invention, the test report of the aging test includes the following project parameters, which include tolerance temperature, tolerance humidity, test time, test angle and yield rate. The test evaluation is performed based on the above project parameters, and the evaluation formula is as follows:

[0067] ;

[0068] in, is the temperature tolerance score, which needs to be normalized according to the inverter's temperature tolerance range; is the humidity tolerance score, which also needs to be normalized; is the test time in hours; It is the test angle score, which is normalized based on the maximum tilt angle required to be carried in actual use; is the yield rate, usually expressed as a percentage; It is a reliability factor, which can be calculated based on MTBF (mean time between failures) or other reliability indicators; is a safety factor, where points may be given based on safety testing or compliance with safety standards.

[0069] in , , , , , , is the importance weight of each parameter, which is adjusted according to specific needs, and their sum is 1.

[0070] Test data and weight settings:

[0071] Temperature tolerance score ( ): 8.5 (out of 10);

[0072] Humidity tolerance score ( ): 7.0 (out of 10);

[0073] Test time( ): 500 hours;

[0079] =0.15×8.5+0.10×7.0+0.20×log(500)+0.10×8.0+0.20×0.95+0.15×9.0+0.10×9.5;

[0080] Right now =1.275+0.7+0.5396+0.8+0.19+1.35+0.95≈5.8046;

[0081] Therefore, in this example, the evaluation score of the high voltage inverter is about 5.80.

The test plate (620) is provided with test positions distributed in a matrix. The loading mechanism (300) vertically inserts the test piece (800) into the test position. The test piece (800) performs a cyclic motion along with the cyclic track assembly (500). S2: Entering the first test condition, at which time the movement of the suspension component (700) and the circulating track component (500) is synchronized, the simulation component (900) on the suspension component (700) is facing the test component (600) for testing, and when the simulation component (900) passes through the ascending section, descending section and transition section in the suspension track (710), the test height between the simulation component (900) and the test component (600) is changed, and changing the test height changes the test intensity of the test solar light panel (910); S3: After the first test condition is cycled, a second test condition is performed. The second test condition is to set a plurality of test components (600) on the circulating track component (500), and the test components (600) are evenly distributed at corresponding test stations. Then, the suspension component (700) is used to cycle and drive the simulation component (900) to perform periodic testing. Changing the test angle changes the angle at which the test solar light panel (910) irradiates the test object (800). S4: During the test, adjust the air moisture content and air average temperature parameters within the test frame; S5: During the test process, if the test result of the test piece (800) is not good, the test piece (800) is clamped and unloaded by the unloading mechanism (400). After the test piece (800) is unloaded, it is transferred to the loading mechanism (300), and the loading mechanism (300) replenishes it accordingly; S6: Through periodic testing, the batch aging test of the test pieces (800) is completed.
