How to solve the problem of electrical equipment not working after AC connection?

After the AC output is connected to an electrical appliance, the appliance cannot be used, which may be caused by a problem with the external electrical appliance or an internal malfunction of the energy storage power supply. If your power supply has the following problems, please follow the steps in this article to troubleshoot and solve the output problem.

Phenomenon: After AC connection to the appliance, the appliance cannot be used

Step: Check the storage power supply display

When the normal stored energy power supply has enough power, the AC green indicator will light up to show the output power, and the power will gradually decrease; models with voltage and frequency display will show the voltage and frequency. If it is not available, it is an internal fault.

Solution: Contact customer service personnel for after-sales treatment.

Remarks: You need to check whether the power of the appliance is suitable before use. The power of the appliance must be equal to or less than the rated power of the energy storage power supply, and it is better to leave a certain margin (the power of the appliance has deviation).
