5. Einrichtung und Installation

Proper installation is crucial for the optimal performance and longevity of your solar charge controller. Ensure all connections are secure and follow the recommended wiring sequence.

5.1. Montage des Controllers

• Mount the controller in a well-ventilated area, away from direct sunlight and moisture.
• Ensure sufficient clearance around the unit for proper airflow, especially around the exhaust fans and the back fence mesh design for heat dissipation.
• The controller should be mounted vertically on a non-flammable surface.

5.2. Kabelverbindungen

Follow the wiring sequence below to prevent damage:

1. Schließen Sie die Batterie an: First, connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the 12V or 24V system voltage.
2. Schließen Sie die Solarpaneele an: Next, connect the solar panels to the controller's solar terminals. Verify correct polarity.
3. Last anschließen (optional): Finally, connect your DC loads to the controller's load terminals.

The power terminals accommodate 10 AWG wiring. For optimal performance, use appropriate wire gauges for all connections.

6. Bedienungsanleitung

Once installed, the controller will begin operating automatically. The built-in LCD display provides real-time information about your solar system.

6.1. LCD Display and Monitoring

The blacklight LCD display shows various parameters simultaneously, including:

• Solarpanel Voltage (PV) and Current (A)
• Batterie Voltage (BATT) and State of Charge (%)
• Last Voltage (LOAD) and Current (A)
• Cumulative power (KWH)
• Umgebungstemperatur
• Charging Faults or Errors
• Laststatus (EIN/AUS)

The controller automatically tracks real-time data changes in these parameters, providing a comprehensive overview of your system's performance.

6.2. External Display (Optional)

An optional external display unit (LCD D485) can be connected via the RS485 communication port. This unit allows for remote monitoring and adjustment of controller functions and parameters, offering greater flexibility in system management. The external display package includes a 1.5-meter extension cable for convenient placement.

7. Wartung

Regular maintenance ensures the long-term reliability and efficiency of your OOYCYOO MPPT Solar Charge Controller.

• Sauberkeit: Halten Sie den Controller sauber und frei von Staub und Schmutz. Verwenden Sie zum Reinigen ein trockenes Tuch.
• Verbindungen: Überprüfen Sie regelmäßig alle Kabelverbindungen, um sicherzustellen, dass sie fest sitzen und frei von Korrosion sind.
• Belüftung: Ensure that the cooling fans and ventilation openings are not obstructed. The built-in cooling fan activates when the internal temperature exceeds 45°C and turns off below 40°C, contributing to a longer lifespan (up to 5000 hours in normal use).
• Batterieinspektion: Regularly inspect your batteries for any signs of damage or leakage.

8. Fehlerbehebung

If you encounter issues with your solar charge controller, refer to the following common problems and solutions. For complex issues, please contact customer support.

• Kein Display/Stromanschluss: Überprüfen Sie die Batterieanschlüsse und stellen Sie sicher, dass die Batteriespannung ausreichend ist.tage liegt innerhalb des Betriebsspannungsbereichs (9V-32V).
• Kein Aufladen: Verify solar panel connections and ensure sufficient sunlight. Check for PV over current/power or short circuit protection activation.
• Laden funktioniert nicht: Check load connections and ensure the load is not overloaded or short-circuited. Verify battery voltage liegt über dem niedrigen Voltage Trennschwelle.
• Überhitzung: Ensure adequate ventilation around the controller. Check if the cooling fans are operating correctly when the unit is warm.
• Fehlercodes: Refer to the LCD display for specific error codes. Consult the detailed manual or contact support for interpretation.
