Safety Information
Observe the following safety precautions to prevent injury and damage to the product:
- Do not attempt to disassemble or modify the solar panel or controller.
- Ensure all connections are secure and correctly polarized before applying power.
- Avoid touching exposed wires or terminals when the panel is exposed to sunlight.
- Keep the solar panel and controller away from flammable materials and excessive heat.
- Install the system in a well-ventilated area to prevent overheating.
- Use appropriate personal protective equipment (PPE) during installation.
Setup
Follow these steps for proper installation of your solar panel kit:
1. Unpacking and Inspection
Carefully remove all components from the packaging. Inspect each item for any signs of damage. If any component is damaged, do not proceed with installation and contact customer support.
2. Solar Panel Placement
Position the solar panel in a location that receives maximum direct sunlight throughout the day. Avoid shaded areas. The included suction cups can be used for temporary mounting on smooth surfaces like glass.

3. Connecting the Solar Charge Controller
The solar charge controller manages the power flow from the solar panel to your battery and load. Connect the components in the following order:
- Connect the Battery: First, connect your 12V or 24V battery to the battery terminals on the solar charge controller. Ensure correct polarity (positive to positive, negative to negative). The controller display should illuminate.
- Connect the Solar Panel: Next, connect the solar panel to the solar input terminals on the controller. Ensure correct polarity. The controller will begin charging the battery if sufficient sunlight is available.
- Connect the Load (Optional): If you have a DC load (e.g., LED lights), connect it to the load terminals on the controller. The controller will manage power delivery to the load, protecting the battery from over-discharge.
Note: Always connect the battery first and disconnect it last to prevent damage to the controller.

Operating Instructions
Once connected, the solar charge controller will automatically manage the charging process. The display on the controller provides real-time information about the system's status.
Controller Display and Buttons
The controller features a digital display and several buttons for monitoring and setting parameters. Refer to the markings on your specific controller for detailed button functions (e.g., 'SET voltage', 'MCU control', 'Build-in timer', 'FULL protect').
- Battery Voltage: Displays the current battery voltage.
- Charging Status: Indicates if the battery is currently being charged.
- Load Status: Shows if the DC load is active.
- USB Output: The controller includes USB ports for charging small electronic devices.
Charging Process
The controller uses Pulse Width Modulation (PWM) technology to efficiently charge your battery, preventing overcharging and extending battery life. It automatically detects 12V or 24V battery systems.
Maintenance
Regular maintenance ensures optimal performance and longevity of your solar panel kit.
- Solar Panel Cleaning: Periodically clean the surface of the solar panel with a soft, damp cloth to remove dust, dirt, and debris. A clean panel ensures maximum sunlight absorption.
- Connection Checks: Annually inspect all electrical connections for tightness and corrosion. Loose or corroded connections can lead to power loss or system failure.
- Controller Environment: Ensure the solar charge controller remains in a dry, well-ventilated area, free from direct sunlight or extreme temperatures.
Troubleshooting
If you encounter issues with your solar panel kit, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output from solar panel | Insufficient sunlight; panel dirty or shaded; damaged panel. | Relocate panel to direct sunlight; clean panel surface; inspect for physical damage. |
| Controller display off or not working | Battery not connected or low voltage; incorrect battery polarity; controller fault. | Check battery connections and voltage; ensure correct polarity; if problem persists, contact support. |
| Battery not charging | Solar panel not connected; low solar input; faulty controller or battery. | Verify solar panel connections; ensure adequate sunlight; test battery and controller. |
| Load not receiving power | Load terminals incorrectly wired; battery voltage too low; controller load setting. | Check load wiring and polarity; ensure battery is sufficiently charged; adjust controller load settings if applicable. |
If troubleshooting steps do not resolve the issue, please contact BROLEO customer support for further assistance.
