2. الإعداد والتثبيت

2.1 تركيب وحدة التحكم

Mount the charge controller vertically on a non-flammable surface in a well-ventilated area. Ensure adequate clearance around the unit for proper heat dissipation. Maintain a minimum clearance of 150mm (approximately 6 inches) above and below the controller for optimal airflow.

Figure 2.1: Mounting Clearance. This diagram illustrates the recommended minimum clearance of 150mm (6 inches) above and below the charge controller to ensure proper air circulation for cooling.

2.2 توصيلات الأسلاك

Follow the wiring diagram carefully. Always connect the battery first, then the solar panels, and finally the DC load. Disconnect in the reverse order.

1. توصيل البطارية: Connect the battery bank to the BAT+ and BAT- terminals. Ensure correct polarity.
2. توصيل الألواح الشمسية: Connect the solar panel array to the PV+ and PV- terminals. Observe correct polarity and ensure the open-circuit voltage of the solar array does not exceed the controller's maximum input voltagه (150 فولت).
3. توصيل الحمل بالتيار المستمر (اختياري): Connect your DC loads to the LOAD+ and LOAD- terminals.
4. قم بتوصيل مستشعر درجة الحرارة (اختياري): If using, connect the external temperature sensor to the designated port for accurate battery temperature compensation.
5. Connect Inverter (Optional): If an inverter is used, connect it directly to the battery bank, not through the load terminals of the controller.

2.3 التشغيل المتوازي (اختياري)

Multiple charge controllers can be connected in parallel using the RS485 communication ports for larger solar systems. Ensure all controllers are properly configured for parallel operation according to the specific system requirements.

Figure 2.3: RS485 Parallel Wiring Diagram. This diagram illustrates how to connect multiple MPPT charge controllers (Host, Slave 1, ..., Slave N) in parallel using RS485 communication for a shared 12V, 24V, 36V, or 48V storage battery system.

It also illustrates the navigation flow through various parameters like Main Monitoring Page, Component Voltage, Charging Current, Battery Voltage, Battery Capacity, Load Current, Charging Capacity, Device Temperature, Discharging Capacity, Load Mode, and Abnormality Codes.

3.2 شحن البطارية S.tages

The MPPT charge controller employs advanced charging algorithms to optimize battery life and performance. The charging process typically involves several stagالعربية:

• Fast Charging (Bulk): يوفر أقصى تيار لشحن البطارية بسرعة.
• Sustaining Charging (Absorption): يحافظ على حجم ثابتtage to fully charge the battery without overcharging.
• الشحن العائم: يقلل الحجمtage إلى مستوى أقل للحفاظ على شحن البطارية بالكامل والتعويض عن التفريغ الذاتي.
• Equalizing Charging (for specific battery types): Periodically overcharges the battery at a controlled rate to balance cell voltages ومنع الكبرتة.

3.3 اختيار نوع البطارية

The controller supports various battery types. It is crucial to select the correct battery type in the settings to ensure proper charging parameters and prevent damage to the battery. Options typically include:

• س ل د: مختومة بطارية الرصاص الحمضية
• فلوريدا: Open Lead-Acid Battery (Flooded)
• جل: بطارية الجل
• لي: بطارية الليثيوم
• المستعمل: User-defined parameters for custom battery types.

3.4 Bluetooth Module (Optional)

An optional Bluetooth module (BT-1) can be connected to the controller for remote monitoring and parameter adjustment via a mobile application. Refer to the Bluetooth module's specific instructions for pairing and app usage. Note that some users have reported intermittent connectivity issues with the mobile application.

4. الصيانة

Regular maintenance ensures optimal performance and longevity of your charge controller.

• التفتيش البصري: Periodically check all wiring connections for tightness and signs of corrosion. Ensure no cables are frayed or damaged.
• نظافة: حافظ على نظافة وحدة التحكم وخلوها من الغبار والحطام. تأكد من عدم انسداد فتحات التهوية.
• تعويض درجة الحرارة: The controller automatically adjusts charging parameters based on battery temperature if an external temperature sensor is connected. Ensure the sensor is properly installed and functioning for accurate compensation, especially in environments with significant temperature fluctuations.
