Connecting to Your Battery
The charger comes with three different connection cables:
- Battery Clamp Cable: Connect the red clamp to the positive (+) terminal of your 12V battery and the black clamp to the negative (-) terminal.
- Cigarette Lighter Cable: Plug this into your vehicle's 12V cigarette lighter socket. Note that some vehicles may require the ignition to be on for the socket to be active.
- Bare Wire Cable: For custom installations, connect the bare wires directly to your battery terminals or a suitable 12V power source, ensuring correct polarity.
Always ensure correct polarity (red to positive, black to negative) to prevent damage to the battery or charger.

Operating Instructions
LED Indicator Status
The solar charger features an LED indicator that provides feedback on its operational status:
- Solid Red: Indicates error or reversed polarity.
- Solid Green: Battery is fully charged.
- Blinking Red: Working to charge the battery (activated).
- Blinking Green: Sunshine is effective (not active yet).

Troubleshooting
If the solar charger is not functioning as expected, please refer to the following:
- No LED Indication: Ensure the solar panel is in direct sunlight and properly connected to the battery. Check for any obstructions on the panel surface.
- Solid Red LED: Indicates reversed polarity or an error. Disconnect and reconnect, ensuring correct positive and negative connections.
- Blinking Green LED but no charge: Ensure the battery is not already fully charged. If the battery is severely discharged, it may take some time for the charger to initiate a full charge cycle.
- Low Charging Rate: Ensure the panel is receiving maximum sunlight exposure. Clean the panel surface if dirty.
