Abnormal charging power

The following factors may cause a decrease in the power generation of the solar panel:

1. It is related to solar radiation intensity, solar irradiance, sunlight duration, and the positioning of the solar panel.
2. If the surface of the solar panel is dirty, power generation will decrease.
3. If the solar panel has been dropped or impacted, it may be damaged, which can also reduce power output.
4. The power station uses a CCCV charging method. When the battery approaches full capacity, the solar panel's power output will automatically adjust and decrease.
   CCCV (Constant Current / Constant Voltage) charging starts with constant current (CC) until the battery reaches a specified voltage. Then, the system switches to constant voltage (CV) to complete the charge, preventing overcharging. The charging speed slows significantly during the final few percent.
5. There may be a malfunction in the solar panel itself.

To investigate the cause of the reduced power output, please confirm the following:

1. On a clear sunny day, place the solar panel under direct sunlight between 12:00 PM and 2:00 PM. Check whether the output exceeds 60%.
2. Ensure the panel is not shaded or blocked.
3. Since the power output will decrease when the power station is nearly full, please test the panel when the battery level is below 50% and check whether it exceeds 60%.
4. Has the solar panel ever been dropped or suffered an impact during use?
5. Try using a different DC input port for testing.
6. Check if there are any error codes or unusual symbols on the screen.

If the issue still cannot be resolved, please record a clear video showing the charging process and screen display, and send it to our support email [e-mail].
