Read all instructions before use. Failure to follow safety guidelines may result in injury or damage.
WARNING! Never short-circuit the output terminals. Do not expose to extreme heat above 158°F (70°C).
Unpack and inspect contents. Ensure all components are present and undamaged.
CAUTION! Do not bend the panel excessively. Avoid placing heavy objects on the panel surface.
Power generation begins automatically when the panel is exposed to sunlight and a device is connected.
Using USB Ports: Connect smartphones, tablets, power banks, or USB lights directly. The USB-C port supports Power Delivery for fast charging compatible devices.
Using DC Output: Connect to a 12V battery using the alligator clips (Red to positive, Black to negative). The integrated controller prevents overcharging.
Using with Power Stations: Connect the DC 5521 cable to the DC input of a compatible portable power station.
Performance Note: Actual output power depends on sunlight intensity, angle, temperature, and cloud cover.
Ensure the device or battery voltage is compatible (12V nominal for DC output).
Tip: For best results, clean the panel surface before use and adjust the angle every few hours to follow the sun.
Proper care extends the life of your solar panel.
CAUTION! Do not immerse the charge controller or connectors in water. Although the panel is IP67, prolonged submersion is not recommended.
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| No power output | Insufficient sunlight, poor connection | Move panel to direct sun; check all cable connections are secure. |
| Low charging speed | Cloudy day, wrong panel angle, high temperature | Adjust panel angle; wait for better conditions; allow panel to cool if hot. |
| Device not charging via USB | Incompatible device, faulty cable | Try a different USB cable; ensure device supports charging via solar input. |
| Battery not charging via DC | Battery fully charged, reverse polarity, battery fault | Check battery voltage; verify correct clip connection (Red+/Black-). |
| LED indicator not on | No sunlight, internal fault | Ensure panel is in sun. If problem persists, contact support. |
Reset: Disconnect all devices, fold the panel, wait 5 minutes, then redeploy in sunlight.
