4. Setup and Installation
Follow these steps for optimal setup:
- Initial Charge: Upon first receiving the item, it is recommended to use the USB port for charging to ensure the battery has sufficient power. This initial charge helps in activating the battery and preparing the lights for use.
- Solar Panel Placement: Choose a location for the solar panel that receives direct sunlight for at least 6-8 hours daily. The panel can be installed by ground plugging using the included stake or fixed to a wall/surface with screws. Ensure the panel is positioned parallel to the ground for most effective charging during the day.
- String Light Installation: Carefully uncoil the string lights. Hang them in your desired outdoor area, ensuring the bulbs are securely seated in their sockets. The 6FT lead wire provides flexibility for placing the solar panel away from the main light string.
- Connect Solar Panel: Connect the string lights to the solar panel. Ensure the connection is secure to maintain waterproof integrity.

6. Maintenance
To ensure the longevity and optimal performance of your string lights, consider the following maintenance tips:

- Check Connections: Periodically inspect all connections to ensure they are secure and free from corrosion or damage.
- Bulb Replacement: While durable, if a bulb needs replacement, use the provided spare bulbs. The bulbs are designed for easy screw-in replacement.
