5. Impostazione
- Aprire il pannello: Dispiegare con cautela il pannello solare completamente su una superficie piana e stabile.
- Posizionare il cavalletto: 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.
- Fissare il pannello (facoltativo): For windy conditions or uneven terrain, use the provided carabiners to secure the panel through its grommets to stakes, ropes, or other stable anchors.
- Connetti al dispositivo: 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. Istruzioni per l'uso
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.
- Esposizione alla luce solare: Ensure the solar panel is positioned in direct sunlight with no shadows obstructing the panels. Even partial shading can significantly reduce efficiency.
- Commissione di monitoraggio: Monitor the charging status on your connected power station or solar charge controller.
- Compatibilità: 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.
