First, the Structural Parts of the switch body defect caused a small amount of gas leakage. This kind of leakage is usually not detected, only after a long time of accumulation, reduced to a certain degree, can be detected.

Otherwise, the factory Settings will be affected.
Fifth, when the inverter controller prompts overvoltage protection, overcurrent protection or discharge protection, please exit the test, reset the voltage, current protection value or check whether the grounding line is good, and then enter the test.
