3. TROUBLESHOOTING GUIDE

It is only for the authourized technicians when testing and repairing. Non-authorized person should

never disassemble or repair the power station and contact the supplier or customer center.

PROBLEM

WITH

LCD

SCREEN

Situation 1

The blue LED light is on, the button and the AC and DC output work normally,

Incomplete display information such as white screen, white dots, white lines, and color

cast appear on the display

Blue Indicator Light

LCD Display

Reason

Solution

Damage caused by strong impact, falling from height, or exposure to high temperatures for a

long time, etc

Power on and off the power station again to confirm whether the abnormality is eliminated;

check whether all external devices of the power station and the charging input terminal are all

unplugged, disassemble the PCB board-A where the display screen is located, and replace

the display screen with a new one. When replacing, pay attention to whether the

corresponding display driver chip is consistent.

PROBLEM

WITH

POWER

Situation 1

Reason

Most of the reasons for this phenomenon are that the power switch reaches the service

lifetimes, and the BMS triggers the shutdown command after the battery is stored with zero

power for a long time.

Main Power Switch

Solution

he blue indicator light is off, and the display screen is black.

Switch the main power switch in the "O" position and plug in the charger. Then check

whether the display screen shows normal. If the battery charge level rises normally, the

power on/off switch may be faulty.

In this case, unplug the charger first, and check whether all external devices of the power

station and the charging input are unplugged then proceed replacement of the power

switch.

If the battery power is always below 1%, there may be a problem with BMS or battery pack.

Check whether all external devices of the power station and the charging input are all

unplugged first, and check whether the battery voltage of each string is normal. If the

battery voltage is below 1 V, replace the battery pack. If not, replace the PCB board D.

PROBLEM

WITH

CHARGING

Situation 1

Reason

Situation

Reason

Solution

Most of the reasons for this phenomenon are caused by damage to the charger or poor

contact with the charging port.

Input Connector

Check the charging port whether have foreign objects, oxidation, looseness. If no

abnormality is found, replace the charger of the same specification

The display shows the charging icon , but the battery charge level does not

change . When the charging voltage is higher than the maximum input voltage ,

the charging overvoltage protection function is triggered.

Switch the main power switch in the "o" position first and check whether all the external devices

of the power station and the charging input terminal are all unplugged. Then check that the AC

or DC button is pressed to cause the display to be black, and replace the corresponding PCB-A

board after confirmation.
