5. Setup
- Unfold the Panel: Carefully unfold the solar panel completely on a flat, stable surface.
- Position the Kickstand: Extend the integrated kickstand at the back of the panel. Adjust it to achieve an optimal angle (approximately 70 degrees from the ground) to face the sun directly. This angle maximizes solar energy absorption.
- Secure the Panel (Optional): For windy conditions or uneven terrain, use the provided carabiners to secure the panel through its grommets to stakes, ropes, or other stable anchors.
- Connect to Device: Locate the MC4 connectors on the solar panel. Use the included multi-connector cable to connect the solar panel to your portable power station, solar generator, or 12V/24V battery system. Ensure the correct adapter is used for your device.

6. Operating Instructions
Once set up, the solar panel will begin converting sunlight into electrical energy. The charging process will vary depending on the connected device (power station, battery, etc.) and its specific charging requirements.
- Sunlight Exposure: Ensure the solar panel is positioned in direct sunlight with no shadows obstructing the panels. Even partial shading can significantly reduce efficiency.
- Monitoring Charge: Monitor the charging status on your connected power station or solar charge controller.
- Compatibility: The panel is designed for wide compatibility, including various portable power stations and 12V/24V battery systems. It includes a 4-in-1 universal connector (MC4, DC5525, DC7909/8mm, Anderson, TX60) to support most devices.

7. Maintenance
- Cleaning: Regularly wipe the surface of the solar panels with a soft, damp cloth to remove dust, dirt, or debris. A clean surface ensures maximum light absorption and efficiency. Do not use harsh chemicals or abrasive materials.
- Inspection: Periodically inspect the panel for any physical damage, such as cracks, dents, or frayed cables. Ensure all connectors are clean and free of corrosion.
- Storage: When not in use, fold the solar panel and store it in a dry, cool place away from direct sunlight and extreme temperatures. Use the integrated handle for easy transport.
