3.3 Wiring Instructions
Follow the connection order carefully to avoid damage to the controller or other components.
- Connect the Battery: First, connect the battery to the controller's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The controller will automatically detect the battery voltage (12V/24V/36V/48V).
- Connect the Solar Panels: Next, connect the solar panel array to the controller's solar panel terminals. Ensure correct polarity.
- Connect the Load: Finally, connect your DC loads to the controller's load terminals.
Disconnection Order: To disconnect the system, reverse the order: first disconnect the load, then the solar panels, and finally the battery.
Wire Gauge: Use 10 AWG wire for power terminals to ensure optimal performance and safety.
3.4 Battery Compatibility
The controller is compatible with a wide range of battery types, including:
- AGM (Absorbent Glass Mat)
- Sealed Lead-Acid
- Gel
- Flooded Lead-Acid
- Lithium (LiFePO4, Li(NiCoMn)O2) - User programmable
4. Operating Instructions
4.1 LCD Display
The integrated blacklight LCD display provides real-time information about your solar system's performance. It shows parameters such as battery voltage, charging current, load current, and accumulated energy (KWH).
4.2 System Settings
The controller allows for user-programmable settings to optimize charging for different battery types and system requirements. These settings typically include:
- Battery Type Selection: Choose the appropriate battery type (AGM, Gel, Flooded, Lithium, or USER-defined).
- Absorption Voltage: Set the voltage at which the battery is held during the absorption charging stage.
- Floating Voltage: Set the voltage at which the battery is maintained after absorption, to keep it fully charged.
- Low Voltage Disconnect (LVD): Configure the voltage threshold at which the load will be disconnected to protect the battery from over-discharge.
- Load Timer: Program the operating hours for the DC load output.
Refer to the detailed instructions within the controller's interface for navigating and adjusting these settings.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your solar charge controller.
- Cleaning: Periodically clean the controller's exterior with a dry cloth. Ensure vents are free from dust and debris to maintain proper airflow.
- Connection Checks: Annually inspect all wiring connections for tightness and signs of corrosion. Loose connections can lead to overheating and system inefficiency.
- Fan Operation: The built-in cooling fan will activate automatically when the internal temperature exceeds 45℃ and turn off when it drops below 40℃. Ensure the fan is not obstructed and operates freely.
- Environmental Check: Verify that the installation environment remains dry and free from excessive humidity or extreme temperatures.
6. Troubleshooting
If you encounter issues with your OOYCYOO MPPT Solar Charge Controller, consider the following general troubleshooting steps:
- No Display/Power: Check battery connections and ensure the battery voltage is within the controller's operating range. Verify that the battery is charged.
- No Charging: Confirm solar panel connections and polarity. Check for sufficient sunlight and ensure solar panel voltage is above the battery voltage. Inspect for any blown fuses in the solar array.
- Load Not Working: Check load connections and ensure the load is not exceeding the controller's rated current. Verify that the battery voltage is above the Low Voltage Disconnect (LVD) setting.
- Overheating: Ensure the controller is mounted in a well-ventilated area and that its cooling vents are not obstructed. Reduce the load if consistently overheating.
- Error Codes: If the LCD displays an error code, consult the specific error code section of the full user manual (if available) or contact customer support.
For persistent issues, it is recommended to contact OOYCYOO customer support.
