Abnormal parallel connection of the energy storage power supply may be caused by the connection between the parallel device, the energy storage power supply, and the internal failure of the energy storage power supply. If the following problems occur in the use of your power supply, please follow the steps in this article to troubleshoot and solve the problem of parallel expansion.
Phenomenon: Two power supplies fail to parallelize through the parallel device and cannot be used normally.
Please follow the steps below to deal with the paralleling problem
Step 1: Check the parallel device (JACKERY connector)
Check the connection between the 2 main units. The screen will display the parallel symbol if the normal connection is successful. Parallel operation is prohibited in the output state. If the parallel symbol is not displayed, try reconnecting.
Step 2: Check the energy storage display
Check the AC output frequency (50/60Hz) of the two hosts. The screen will display the parallel symbol after the output frequency is the same and the parallel operation is successful. If the output frequency is not the same it will cause the parallelization failure.
Step 3: Check the overcurrent protection switch of the parallel device.
The overcurrent protection switch of the parallel device is normally closed. If it pops up, you need to press it.
If the connection is normal, the frequency is consistent and the power is sufficient, but the power devices still can not be paralleled with each other, it means that there is an internal failure.
Solution: Contact customer service personnel for after-sale treatment.
Remarks: It is forbidden to connect 2 main units under a power-on state. The parallel operation must be carried out under a power-off state.
