6. Setup & Installation

6.1. Unboxing and Overview

Upon unboxing, inspect the charge controller for any visible damage. Familiarize yourself with the device's layout and connection points.

6.2. Mounting

Mount the charge controller vertically on a non-flammable surface in a dry, well-ventilated area, away from direct sunlight and heat sources. Ensure sufficient clearance around the unit for proper airflow, especially around the cooling fans.

6.3. Wiring Connections

Follow the wiring sequence carefully to avoid damage to the controller or batteries. The controller accepts up to 6 AWG wire for main power connections. Ensure all connections are tight and secure.

1. Battery Connection: Connect the battery cables to the BATTERY terminals on the controller first. Ensure correct polarity (positive to positive, negative to negative).
2. Solar Panel Connection: Connect the solar panel cables to the SOLAR PANEL terminals. Ensure correct polarity.
3. Load Connection (Optional): If using the DC load output, connect your DC loads to the DC LOAD terminals. Ensure correct polarity.
4. Temperature Sensor: Plug the included temperature sensor into the designated port. Attach the sensor to the battery for accurate temperature compensation during charging.

6.4. Initial Configuration

After all connections are made, the controller will power on. You may need to configure the battery type and system voltage if it's not automatically detected or if you are using a custom battery type like Lithium.

The controller features a blacklight LCD display for easy monitoring and configuration. Use the buttons to navigate through the menu and adjust settings as needed. For detailed instructions on setting battery parameters, refer to the specific section in the printed user manual.

7. Operating Instructions

The LCD display provides real-time information about your solar system. Use the navigation buttons (Menu, Up, Down, Enter) to view different parameters and access settings.

7.1. LCD Display Overview

The display shows various parameters such as:

• PV Voltage and Current
• Battery Voltage and Charging Current
• Load Voltage and Current
• Battery Capacity Percentage
• Ambient Temperature
• Cumulative Power Generation (KWH)
• Error/Fault Indicators

7.2. Setting Battery Parameters

To optimize charging for your specific battery type, you can adjust parameters like absorption voltage, float voltage, and low voltage disconnect. Consult the detailed instructions in the full user manual for precise steps on how to enter the settings menu and modify these values.

7.3. Load Control

The controller features a programmable load timer. You can set the load to turn on/off at specific times or based on battery voltage levels. This feature helps conserve battery power and manage your DC loads efficiently.

8. Maintenance

• Regularly check all wiring connections for tightness and corrosion.
• Keep the controller's cooling vents clear of dust and debris to ensure proper heat dissipation.
• Periodically inspect the battery terminals for corrosion and clean if necessary.
• Monitor the LCD display for any error codes or unusual readings.

9. Troubleshooting

If you encounter issues with your OOYCYOO MPPT Solar Charge Controller, refer to the following general troubleshooting tips:

• No Display/No Power: Check battery connections and ensure the battery voltage is above the minimum operating voltage.
• No Charging: Verify solar panel connections and ensure sufficient sunlight. Check for any PV over current/short circuit protection activation.
• Battery Over-Discharge: Adjust the low voltage disconnect setting if necessary. Ensure your loads are not exceeding the battery's capacity.
• Error Codes: Consult the full user manual for a list of specific error codes and their corresponding solutions.
