Ensure correct polarity (positive to positive, negative to negative).
- Connect Devices: For direct device charging, plug your USB devices into the USB ports on the charge controller.
Operating Instructions
- Monitor Charging Status: The charge controller features an LCD display that shows real-time charging status, battery voltage, and current. Refer to the display for operational information.
- Adjust Battery Type: The charge controller allows you to select the battery type (Gel, AGM, Liquid-Acid) to ensure optimal charging parameters for your specific battery. Consult the charge controller's separate manual (if provided) for detailed instructions on how to change this setting.
- Charging Devices via USB: Simply connect your USB-powered devices (e.g., smartphones, tablets) to the USB ports on the charge controller. The controller will automatically regulate the output for safe charging.
- Load Output (if applicable): If your charge controller has a "Load" output, you can connect DC loads directly to these terminals. Ensure the load's voltage and current requirements are within the controller's specifications.

Maintenance
- Cleaning: Regularly clean the surface of the solar panels with a soft, damp cloth to remove dust, dirt, or debris. Avoid abrasive cleaners or harsh chemicals that could damage the panel surface.
- Inspection: Periodically inspect all cables and connections for any signs of wear, damage, or corrosion. Ensure all connections are secure.
- Storage: When not in use, fold the solar panel compactly and store it in a dry, cool place away from direct sunlight and extreme temperatures. Protect it from physical damage.
Troubleshooting
