Setup Instructions
Proper setup is crucial for optimal performance of your solar string lights. Follow these steps to ensure efficient charging and operation.
- Unpack Components: Carefully remove the solar string lights and solar panel from the packaging. Each pack contains one string of lights and one solar panel with a ground stake.
- Remove Protective Film: Locate and remove the clear protective film from the surface of the solar panel. This film can hinder charging efficiency.
- Assemble Solar Panel: Attach the ground stake to the solar panel. Ensure it is securely fastened.
- Position Solar Panel: Choose a location for the solar panel that receives direct sunlight for 6-8 hours daily. Avoid shady areas or locations obstructed by trees, buildings, or other structures. The solar panel should face the sun directly for maximum charging.
- Activate Lights: Before the first charge, ensure the power button on the back of the solar panel is set to the "ON" position. The lights will then charge automatically when exposed to sunlight.
- Install String Lights: Carefully uncoil the string lights. The wire is designed to be flexible and can be wrapped around trees, fences, patios, or other desired outdoor structures. The lights come wrapped nicely on a plastic card to prevent tangling during installation.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar string lights.
Cleaning the Solar Panel:
Dust, dirt, and debris can accumulate on the solar panel, reducing its charging efficiency. Periodically wipe the solar panel surface with a soft, damp cloth to keep it clean. Avoid using abrasive cleaners or harsh chemicals.
Battery Information:
The lights are equipped with a rechargeable 1800mAh Ni-MH AA battery. While designed for long-term use, if you notice a significant decrease in illumination time, ensure the solar panel is receiving adequate direct sunlight. The product is designed to be energy-efficient and typically does not require frequent battery replacement.
Weather Resistance:
These lights are IP65 waterproof, meaning they are protected against dust ingress and low-pressure water jets from any direction. They are designed to withstand typical outdoor weather conditions including rain, snow, and wind. However, for extreme weather events, it is advisable to take precautions or temporarily store the lights indoors.

Troubleshooting
If your SANJICHA Solar String Lights are not functioning as expected, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on at night. | Solar panel not receiving enough direct sunlight. Power switch is OFF. Battery charge is too low. | Ensure the solar panel is placed in a location that receives 6-8 hours of direct sunlight daily. Verify the power switch on the solar panel is in the "ON" position. Allow the solar panel to charge for at least 1-2 full sunny days before expecting full performance. |
| Lights are dim or only stay on for a short period. | Insufficient charging due to cloudy weather or obstructions. Solar panel is dirty. Battery capacity reduced over time. | Relocate the solar panel to a sunnier spot. Clean the surface of the solar panel regularly with a soft, damp cloth. While batteries are designed for longevity, extreme temperature fluctuations or prolonged low charge cycles can affect them. Ensure optimal charging conditions. |
| Lights flicker or change modes unexpectedly. | Loose connection or internal component issue. | Check all visible connections. If the issue persists, contact customer support. |
