4. Setup Instructions

Follow these steps to set up your solar trickle charger:

1. Choose Connection Method: Select the appropriate cable for your battery:
• Alligator Clips: For temporary direct connection to battery terminals. Ensure red clip connects to the positive (+) terminal and black clip to the negative (-) terminal.
• O-Ring Terminals: For more permanent connection to battery terminals. Connect red to positive (+) and black to negative (-).
• Cigarette Lighter Plug: For charging via your vehicle's 12V accessory socket. Note: Some vehicle sockets are ignition-controlled and may not provide power when the vehicle is off.
2. Connect to Solar Panel: Plug your chosen connection cable into the SAE quick connector on the solar panel.
3. Mount the Solar Panel: Position the solar panel in direct sunlight for optimal charging. Use the provided suction cups to attach it to a clean, smooth surface like a car windshield or window. Alternatively, use the carabiners to hang the panel.

5. Operating Instructions

Once connected and properly positioned, the solar panel will begin charging your 12V battery. The built-in smart charge controller manages the charging process to prevent overcharging and ensure optimal battery health.

Indicator Lights:

• Blue Light: Indicates that the solar panel is exposed to sufficient sunlight and is generating power.
• Red Light: Indicates that the battery is currently charging.
• Green Light: Indicates that the battery is fully charged. The controller will automatically stop charging to prevent overcharging.
• No Light: If no lights are on, ensure the panel is in direct sunlight and all connections are secure.

6. Maintenance

The SUNAPEX solar panel is designed for low maintenance and long-lasting performance.

• Cleaning: Periodically wipe the solar panel surface with a soft, damp cloth to remove dust, dirt, or debris that may reduce efficiency. Avoid abrasive cleaners or harsh chemicals.
• Waterproof Design: The IP67 waterproof rating ensures the panel can withstand rain, snow, and other weather conditions without damage.
• Durability: Constructed with durable materials like ETFE and anti-ultraviolet fiberglass for extended lifespan.

7. Troubleshooting

If you encounter issues with your solar trickle charger, consider the following:

• No Indicator Lights: Ensure the solar panel is in direct sunlight. Check all cable connections to the panel and the battery for proper contact.
• Blue Light On, No Red Light: This indicates the panel is receiving sunlight but the battery may be fully charged (green light should be on) or there might be an issue with the battery connection. Verify battery terminals are clean and secure.
• Red Light On, No Green Light: The battery is actively charging. Allow more time for the battery to reach full charge.
• Solid Red Light (Error): A solid red light may indicate a short circuit or reverse polarity. Immediately disconnect the panel and recheck all connections, ensuring positive is connected to positive and negative to negative.
• Reduced Charging Efficiency: Ensure the solar panel surface is clean and free from obstructions. Adjust the panel's angle to maximize direct sunlight exposure.
