4. Setup

1. Unfold the Solar Panel: Carefully unfold the ELECAENTA UT-25H solar panel completely to expose all solar cells.
2. Position for Optimal Sunlight: Place the unfolded solar panel in an area with direct and unobstructed sunlight. Angle the panel towards the sun to maximize efficiency. The included carabiners can be used to hang or prop the panel for better sun exposure.
3. Connect Your Device: Locate the USB-C and USB-A output ports on the control box. Use a compatible USB cable to connect your device (e.g., smartphone, power bank) to either the USB-C or USB-A port.
4. Verify Connection: A small LED indicator on the control box will illuminate when the panel is generating power and charging a device.

5. Operating Instructions

1. Maximize Sunlight Exposure: For the fastest and most efficient charging, ensure the solar panel is positioned directly facing the sun. Any shadows or indirect light will reduce charging performance.
2. Charging Multiple Devices: The solar panel supports simultaneous charging through both the USB-C and USB-A ports. Connect your devices to the respective ports. Note that charging two devices simultaneously may distribute the available power, potentially leading to slightly slower charging for each device compared to charging a single device.
3. Charging Indicator: The LED light on the control box indicates power generation. If the light is off, reposition the panel or check for obstructions.
4. Environmental Conditions: While the solar panel is IP68 waterproof, avoid submerging the control box in water. Optimal operating temperatures are typically between -10°C to 60°C (14°F to 140°F). Extreme temperatures can affect performance.
5. Automatic Charge Recovery: The panel features an automatic charge recovery function, meaning it will resume charging automatically once sufficient sunlight returns after a temporary interruption (e.g., passing clouds).

6. Maintenance

• Cleaning: Regularly wipe the solar panel surface with a soft, damp cloth to remove dust, dirt, or debris. This ensures maximum light absorption and charging efficiency. Avoid using harsh chemicals or abrasive materials.
• Storage: When not in use, fold the solar panel and store it in a cool, dry place away from direct sunlight and extreme temperatures.
• Inspection: Periodically inspect the panel and cables for any signs of damage, such as cracks, frayed wires, or loose connections. Do not use the product if it is damaged.

7. Troubleshooting

• Device Not Charging:
  • Ensure the solar panel is in direct, unobstructed sunlight.
  • Check all cable connections to ensure they are secure.
  • Verify that your device is compatible with USB charging and that the cable is functional.
  • The LED indicator on the control box should be lit when charging.
• Slow Charging Speed:
  • Charging speed is highly dependent on sunlight intensity. Ensure maximum direct sunlight exposure.
  • Clean the solar panel surface to remove any dirt or dust that might be blocking sunlight.
  • Use high-quality USB cables, as poor-quality cables can reduce charging efficiency.
  • Avoid charging in shaded areas or during cloudy weather.
• LED Indicator Not Lighting Up:
  • This indicates insufficient sunlight or no power generation. Reposition the panel to a brighter spot.
  • Ensure a device is connected and drawing power.
