The DC screen is a new type of DC system with digital control, protection, management, and measurement. During the commissioning of the DC screen, connect AC power supply to test whether the AC dual power switching device works normally, and whether the voltage at the output of the dual power switching device is normal. After the AC part tests normally, close the AC switch of the charging module in turn, observe whether the module starts normally and measure the output voltage and polarity of the module. After the charging module starts normally the output voltage and polarity are correct, connect the switch of the battery pack and each busbar switch, measure whether the voltage and polarity at the output of the battery pack switch, positive busbar, and the control busbar are correct, and observe whether the direction of the voltmeter is reversed.
