What is the reason why the red dot of solar lamp keeps flashing?

The reasons for the red dot of the solar lamp may be as follows: ‌

‌ solar panel doesn't get enough light ‌ : If the solar panel doesn't get enough light, it won't be able to charge properly, resulting in low battery power and a red dot that lights up or flashes all the time.

‌ solar panel or battery damage ‌ : If there is a problem with the solar panel or battery itself, they may not work properly, causing the red dot to flash continuously.

‌ controller fault ‌ : An internal problem of the controller, such as a loose circuit connection or a fault of the controller, may also cause the red dot to blink.
‌ Damaged or inaccurate adjustment of the photosensor ‌ : the photosensor cannot sense the change of light, which will also cause the red dot to flash continuously.

‌ PV panel voltage is too low ‌ : When the PV panel voltage is too low, the red indicator on the solar controller will blink.

‌ Low or high battery voltage ‌ : If the battery voltage is too low or high, the red light blinks.

Solution to the solar lamp red dot flashing method:Check that the solar panel is blocked ‌ : Make sure that the solar panel is receiving enough light.

‌ Inspect and repair or replace solar panels and batteries ‌ : If the panels or batteries are found to be damaged, they need to be repaired or replaced promptly.

‌ Check the circuit connections of the controller ‌ : Ensure that the circuit connections of the controller are stable and replace the controller if necessary.

‌ Adjust or replace the photosensor ‌ : If the photosensor is damaged or adjusted incorrectly, the sensor needs to be adjusted or replaced.

‌ Check the voltage of the photovoltaic panel ‌ : ensure that the voltage of the photovoltaic panel is within the safe range.

‌ Check and adjust the battery voltage ‌ : Ensure that the battery voltage is within the safe range, and repair or replace the battery if necessary.
