2. Installation and System Connection

Follow these steps for proper installation. Ensure all connections are secure and correct to prevent damage to the controller or other components. Her zaman önce pili bağlayın.

Figure 2: System Connection Diagram.

1. Connect Battery (1): Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect 12V or 24V battery systems.
2. Connect Solar Panels (2): Connect the solar panel(s) to the charge controller. Again, observe correct polarity.
3. Connect DC Load (3 - Optional): Connect your DC loads (e.g., LED lights) to the controller's load terminals. Ensure correct polarity.
4. Connect Inverter (4 - Optional): If using an inverter for AC loads, connect it to the battery terminals. The inverter should not be connected directly to the load terminals of the controller.

Önemli Not: Connect in strict accordance with the sequence: 1. Battery, 2. Solar Panel, 3. Load. Disassembly should be in the reverse order to prevent damage.

Montaj:

• Mount the controller on a vertical surface to allow for proper heat dissipation.
• Ensure adequate clearance around the controller for air circulation.
• Avoid mounting in direct sunlight, high temperatures, or areas prone to water exposure.

3. Kullanım ve Ayarlar

The controller features an LCD display and three buttons for navigation and parameter adjustment.

3.1. LCD Ekran Arayüzü

Figure 3: LCD Display and Button Functions.

• MENÜ Düğmesi: Short press to switch between display interfaces. Long press (3-5 seconds) to enter or exit parameter setting mode.
• YUKARI Düğmesi: In parameter setting mode, press once to increase the parameter value.
• DOWN/ON/OFF Button: In parameter setting mode, press once to decrease the parameter value. In normal display mode, press to turn the load on or off.

The LCD displays various information including voltage, ampere-hour, load output status, battery status, and solar panel charging light indicators (On: Direct/Boost Charge; Slowly Flash: Float Charge).

3.2. Parametre Ayarları

To adjust parameters, long press the MENÜ button for 3-5 seconds to enter the setting interface. Use the UP Ve AŞAĞI buttons to modify values. Long press the MENÜ button again to save and exit, or long press AŞAĞI to restore default parameters.

Figure 4: Parameter Setting Flow.

The common adjustable parameters include:

• Şamandıra Hacmitage: cilttage at which the battery is maintained after full charge.
• Deşarj Yeniden Bağlantı Voltajıtage: cilttage at which the load will reconnect after low voltage bağlantının kesilmesi.
• Deşarj Durdurma Voltajıtage: cilttage at which the load will be disconnected to protect the battery from over-discharge.
• Çalışma Modu: Configures how the load operates (e.g., 24 hours, dusk to dawn, timed).
• Pil Türü: Select the battery type (e.g., B01 for GEL, B02 for Sealed, B03 for Flood). This controller is only applicable to lead-acid batteries (Open type, VRLA, GEL, etc.).

4. Bakım

Düzenli bakım, güneş enerjisi şarj kontrol cihazınızın optimum performansını ve uzun ömrünü sağlar.

• Temizlik: Kontrol cihazını temiz ve toz ve kalıntılardan uzak tutun. Temizlik için kuru bir bez kullanın.
• Bağlantılar: Periodically check all wiring connections to ensure they are tight and free from corrosion. Loose connections can cause overheating and damage.
• Havalandırma: Isının düzgün bir şekilde dağılmasını sağlamak için havalandırma açıklıklarının tıkanmadığından emin olun.
• Çevresel Koşullar: Verify that the controller is operating within its specified temperature and humidity ranges.
• Pil Sağlığı: Pilinizin sağlığını ve şarj seviyesini izleyin.tage regularly. A healthy battery is crucial for the overall system performance.

5. Troubleshooting and Safety Protections

The Thlevel solar charge controller is equipped with multiple safety features to protect itself and your solar power system. Understanding these protections can help in basic troubleshooting.

Figure 5: Built-in Security Protections.

• Kısa devre koruması: Automatically disconnects if a short circuit is detected in the load or solar panel circuit. Check wiring for shorts.
• Aşırı Yük Koruması: Disconnects the load if the current exceeds the rated capacity (20A). Reduce the load or use a higher-rated controller.
• Aşırı Akım Koruması: Similar to overload, protects against excessive current flow.
• Aşırı Şarj Koruması: Stops charging the battery once it reaches the set overcharge voltage, preventing damage.
• hacim altıtage Koruma: Pil voltajı düştüğünde yükü ayırır.tage drops below the set under-voltage threshold, protecting the battery from deep discharge.
• aşırı sestage Koruma: Protects the system from excessively high voltage girişler.
• Ters Polarite Koruması: Protects the controller from damage if the battery or solar panel connections are reversed. However, always ensure correct polarity during installation.

Yaygın Sorunlar:

• Ekran Yok/Güç Yok: Check battery connections and ensure the battery has sufficient charge.
• Pil Şarj olmuyor: Verify solar panel connections, ensure panels are receiving sunlight, and check for any shading. Confirm battery type setting is correct.
• Yük Çalışmıyor: Check load connections, ensure the load is within the controller's current limits, and verify the load work mode settings. The battery might be too low (under-voltage protection activated).
