Operating Instructions

The VOLISUN Solar Post Cap Lights are designed for automatic, hassle-free operation.

  • Automatic Charging: During the day, the integrated solar panel absorbs sunlight, converting it into energy to charge the internal battery. Ensure the solar panel is clean and exposed to direct sunlight for 6-8 hours for optimal performance.
  • Automatic Illumination: At dusk, the light's sensor will detect the decrease in ambient light and automatically turn on the LEDs. The lights will remain illuminated for 10-12 hours on a full charge.
  • Automatic Shut-off: At dawn, the light's sensor will detect the increase in ambient light and automatically turn off the LEDs, initiating the charging cycle again.

Maintenance

Proper maintenance ensures the longevity and optimal performance of your solar post cap lights.

  • Cleaning the Solar Panel: Regularly clean the solar panel with a damp cloth to remove dust, dirt, leaves, or snow. A clean solar panel ensures efficient charging.
  • Weather Resistance: The lights feature an IP64 waterproof rating, allowing them to withstand various outdoor environments, including high temperatures, rain, and snowstorms. The post caps also help protect your posts from weather-related damage.
  • Battery Replacement: The lights use a replaceable 1.2V Ni-MH AA800mAh battery. To replace, unscrew the two screws on the back of the light, carefully lift the protective cover, and swap out the battery. Ensure proper disposal of the old battery.

Troubleshooting

If your VOLISUN Solar Post Cap Light is not functioning as expected, consider the following:

  • Light Does Not Turn On:
    • Ensure the ON/OFF switch on the underside of the light is in the "ON" position.
    • Verify the solar panel is receiving 6-8 hours of direct sunlight daily. Relocate the light if necessary to an area with better sun exposure.
    • Cover the solar panel completely to test if the light illuminates in darkness. If it does not, the battery may need charging or replacement.
  • Short Illumination Time:
    • Clean the solar panel to ensure maximum charging efficiency.
    • Ensure the light is not placed near other strong light sources (e.g., streetlights, porch lights) that might interfere with the automatic sensor.
    • The battery may be old or damaged. Consider replacing the 1.2V Ni-MH AA800mAh battery.
