Solar mobile light towers are complex electromechanical equipment that may encounter various failures. The following are some common faults and their solutions:

1.  The lamp is not bright or the brightness is insufficient:

?  Check the power supply: Make sure that the solar panels are fully charged and check whether the battery and power connection are normal.

?  Check the lamps: Check whether the LED bulb is damaged or aging and needs to be replaced.

?  Check the controller: Check whether the light controller and circuit controller are working properly and need to be repaired or replaced.

2.  The lighthouse cannot start or charge:

?  Check the power connection: Make sure that the power cord is firmly connected and check whether the connection between the battery and the solar panel is normal.

?  Check the charger: Check whether the charger is damaged or faulty and needs to be repaired or replaced.

?  Clean the solar panel: Check the surface of the solar panel for dust or dirt, and clean the surface to ensure charging efficiency.

3.  The lighthouse is tilted or unstable:

?  Adjust the base: Check whether the base of the lighthouse is firm, and adjust the base to ensure that the lighthouse is vertical and stable.

?  Check the support structure: Check whether the support structure is intact, and repair or replace damaged support parts.

4.  Decreased waterproof performance:

?  Check the seal: Check whether the seal of the lighthouse is aging or damaged, and replace the damaged seal to ensure waterproof performance.

?  Clean lamps: Clean the surface of lamps regularly to remove water and dirt to avoid affecting waterproof performance.

5.  Fan failure:

?  Check the fan connection: Check whether the fan power connection is normal, and repair or replace the damaged power cord.

?  Clean the fan: Clean the surface and interior of the fan regularly to remove dust and debris to ensure normal operation.

6.  Controller failure:

?  Reset the controller: Try to reset the controller and restart the lighthouse system.

?  Check the circuit connection: Check whether the controller circuit connection is loose or damaged, repair or replace faulty parts.

7.  Shortened battery life:

?  Check the charging settings: Check whether the charging settings are correct to avoid overcharging or discharge.

?  Battery replacement: After the battery life reaches the expected life, replace the new battery in time to ensure the normal operation of the system.

For complex faults or situations that cannot be solved by yourself, it is recommended to seek the help of professional technicians or after-sales service personnel to ensure that the problem is solved in time and the normal operation of the equipment is restored.
