5. Troubleshooting
If you encounter issues with your EcoFlow Rigid Solar Panels, refer to the following common troubleshooting steps:
- Low Power Output: Ensure panels are clean and free of obstructions (dirt, leaves, snow). Verify that the panels are angled correctly towards the sun for optimal exposure. Check all connections for looseness or corrosion.
- No Power Output: Confirm all cables are securely connected to the solar panels and the power station. Check for any visible damage to cables or connectors. Ensure the power station is turned on and configured to accept solar input.
- Connection Issues: If using an adapter, ensure it is compatible with both the solar panel's MC4 connectors and your power station's input port.
- Physical Damage: Inspect the tempered glass and aluminum frame for cracks, dents, or other damage. Contact customer support if significant damage is found.
