4.2 Indicador d'estat de càrrega
The integrated LED light on the junction box indicates the charging status. When the light is on, the panel is actively generating power and charging your connected devices.
4.3 Smart Load Distribution
The charger features smart load distribution. For peak efficiency, it is recommended to prioritize single-port use, especially when charging high-power devices. The total maximum output across all ports is 40W.
5. Manteniment
5.1 Neteja
To maintain optimal performance, keep the solar panels clean. Gently wipe the ETFE laminate coating with a soft, damp cloth to remove dust or dirt. Avoid using abrasive cleaners or materials that could scratch the surface.
5.2 Emmagatzematge
When not in use, fold the solar panel compactly and store it in a dry, cool place. While the panel itself is IP67 waterproof, the junction box is not fully waterproof. Ensure the junction box is protected from heavy rain or submersion. Avoid submerging the entire solar panel in water for over 30 minutes.
