4. Setup and Installation

Proper installation is crucial for the safe and effective operation of your hybrid charge controller. Please follow these steps carefully:

1. Safety First: Before connecting any components, ensure all power sources (wind turbine, solar panels, battery) are disconnected or turned off. Always handle electrical connections with dry hands.
2. Mounting: Mount the controller in a cool, dry, and well-ventilated area, away from direct sunlight and moisture. Ensure adequate space around the unit for heat dissipation.
3. Battery Connection: Connect the battery to the controller's battery terminals (B+ and B-). Ensure correct polarity. The controller will automatically detect the battery voltage (12V/24V/48V).
4. Solar Panel Connection: Connect your solar PV array to the controller's solar panel terminals (S+ and S-). Observe correct polarity.
5. Wind Turbine Connection: Connect the wind turbine output to the controller's wind turbine terminals.
6. Dump Load Resistor Connection: Connect the provided dump load resistor to the designated dump load terminals on the controller. This resistor is essential for dissipating excess energy from the wind turbine when the battery is full.
7. DC Load Connection: If using DC loads directly from the controller, connect them to the DC load terminals (L+ and L-).
8. Power On: Once all connections are secure and verified for correct polarity, you may re-enable power to the system, starting with the battery, then solar, and finally the wind turbine.

The LCD screen provides real-time data on your system's performance. Key indicators include:

• Battery Voltage (Vbattery): Current battery voltage.
• Charge Indicator: Shows charging status.
• Out Indicator: Shows load output status.
• Power (P): Current power generation from wind and solar.
• Frequency (F): Wind turbine frequency.
• Various other parameters like current, temperature, and error codes may be displayed.

5.2. Control Buttons

• Enter: Used to confirm selections or enter settings menus.
• Up (↑): Navigates up through menu options or increases values.
• Down (↓): Navigates down through menu options or decreases values.
• Esc: Exits current menu or cancels an operation.

5.3. Setting Load Output Modes

The controller allows you to customize the working mode of the load output. Refer to the on-screen menu options using the Up/Down buttons and confirm with Enter to adjust settings such as:

• Load On/Off Schedule: Set specific times for the load to turn on or off.
• Load Control Mode: Choose between always on, light control, or timed control.

6. Maintenance

The GTANND Wind Solar Hybrid Charge Controller is designed for low maintenance. The internal circuit board is sprayed with a three-proof paint, providing protection against dust, moisture, and static electricity. To ensure optimal performance and longevity:

• Periodically inspect all wiring connections to ensure they are tight and free from corrosion.
• Keep the controller's ventilation openings clear of dust and debris to ensure proper heat dissipation.
• Clean the exterior of the controller with a soft, dry cloth as needed. Do not use harsh chemicals or abrasive cleaners.
• Ensure the environment around the controller remains within the specified operating temperature and humidity ranges.

7. Troubleshooting

If you encounter issues with your hybrid charge controller, consider the following common troubleshooting steps:

• No Display/No Power: Check all power connections, including battery, solar, and wind turbine inputs. Ensure the battery has sufficient charge.
• No Charging: Verify that solar panels and wind turbine are producing power. Check connections to the controller. Ensure no protection features (e.g., overvoltage, overcurrent) are active, which might be indicated on the LCD.
• Load Not Working: Check the load connections and ensure the load output mode is correctly configured. Verify that the battery has enough charge to power the load.
• Error Codes on LCD: If an error code is displayed, consult the specific error code section in a more detailed product manual (if available) or contact customer support for assistance.
• Overheating: Ensure the controller is mounted in a well-ventilated area and that its heat sinks are not obstructed.

For persistent issues, please contact GTANND customer support.
