5. Setup Instructions
- Unfold the Panel: Carefully unfold the solar panel blanket completely. Ensure there are no creases or folds that could obstruct sunlight.
- Positioning: Place the solar panel in a location that receives maximum direct sunlight. Consider using the versatile mounting options:
- Lay flat on the ground.
- Drape over a vehicle windshield.
- Hang vertically between trees or on racks using the integrated loops and included shoulder straps.
- Connection to Power Station:
- Locate the MC4 connectors on the solar panel's cable.
- Connect the MC4 connectors to the appropriate adapter (e.g., XT60, Anderson) for your portable power station.
- Plug the adapter into the solar input port of your power station. Ensure the voltage and current are properly matched.
- Connection to Battery System (12V/24V):
- A compatible charge controller (e.g., MPPT) is required for charging 12V/24V battery systems (AGM, LiFePO4, deep cycle).
- Connect the solar panel's MC4 connectors to the solar input of the charge controller.
- Connect the charge controller's output to your battery system.

6. Operating Instructions
- Optimal Performance: For best results, ensure the solar panel is positioned directly facing the sun and is free from any shading. Even partial shading can significantly reduce power output.
- Monitoring: If your power station or charge controller has a display, monitor the input wattage to confirm the panel is generating power. Adjust the panel's angle or position as needed throughout the day to maximize sunlight exposure.
- Weather Conditions: The panel's performance will vary with weather conditions. Clear, sunny days will yield the highest output. Cloudy or overcast conditions will result in lower power generation.
- Temperature: While designed for a wide temperature range, extreme heat can slightly reduce efficiency. Ensure adequate airflow around the panel.

7. Maintenance
- Cleaning: Regularly clean the surface of the solar panel with a soft, damp cloth to remove dust, dirt, or debris. Avoid abrasive cleaners or harsh chemicals.
- Inspection: Periodically inspect the panel and cables for any signs of damage, wear, or loose connections.
- Storage: When not in use, fold the solar panel blanket and store it in a dry, cool place away from direct sunlight and extreme temperatures. Use the integrated straps to secure it.
8. Troubleshooting
- Low Power Output:
- Ensure the panel is in direct sunlight and free from any shading.
- Check for dirt or debris on the panel surface and clean if necessary.
- Verify all connections are secure and correctly made.
- Confirm the power station or charge controller is functioning correctly.
- No Power Output:
- Double-check all cable connections from the panel to the power station/charge controller.
- Ensure the power station or charge controller is turned on and set to receive solar input.
- Test the panel in full direct sunlight to rule out insufficient light conditions.
