دليل مستخدم وحدة التحكم بالطاقة الشمسية POWERTECH MP3752 12 فولت/24 فولت 20 أمبير

1. المقدمة

The POWERTECH MP3752 is an intelligent and lightweight solar charge controller designed to manage the power flow from your solar panels to your battery bank. Utilizing Pulse Width Modulation (PWM) technology, it ensures efficient and safe battery charging. This controller offers a set-and-forget operation, providing maximum charge into your batteries without constant monitoring. It integrates essential safety features such as overload, short-circuit, over-discharge, and reverse-polarity protection. Additionally, a convenient USB port on the front panel allows for up to 1.2A charging, useful for mobile devices during power outages. The unit supports various battery types including sealed lead-acid, Gel, and flooded cells, and automatically selects the optimal charging mode (bulk, equalise, float).

The MP3752 controller features clearly marked terminals for easy connection. Refer to Figure 1 for a visual guide to the controller's layout and indicators.

محطات الاتصال:

• Solar Panel Input (PV): Connect your solar panel array here. Ensure correct polarity (+ and -).
• توصيل البطارية: Connect your 12V or 24V battery bank here. Observe correct polarity (+ and -).
• تحميل الإخراج: Connect your DC loads (e.g., lights, fans) here. Observe correct polarity (+ and -).
• منفذ USB: 5V, 1.2A max output for charging small electronic devices.

6. الإعداد والتثبيت

اتبع هذه الخطوات لتثبيت جهاز التحكم في شحن الطاقة الشمسية بشكل صحيح:

1. التركيب: Choose a dry, well-ventilated indoor location, away from direct sunlight, high temperatures, and moisture. Ensure sufficient air circulation around the controller.
2. توصيل البطارية:
   • Connect the positive (+) terminal of the battery to the battery positive (+) terminal on the controller.
   • Connect the negative (-) terminal of the battery to the battery negative (-) terminal on the controller.
   • The controller will automatically detect if it's a 12V or 24V system.
3. اتصال الألواح الشمسية:
   • Connect the positive (+) terminal of the solar panel to the solar panel positive (+) terminal on the controller.
   • Connect the negative (-) terminal of the solar panel to the solar panel negative (-) terminal on the controller.
   • Ensure the open-circuit voltage of the solar panel does not exceed the maximum input voltage of the controller (typically 50V for 12/24V systems).
4. اتصال التحميل:
   • Connect the positive (+) terminal of your DC load to the load positive (+) terminal on the controller.
   • Connect the negative (-) terminal of your DC load to the load negative (-) terminal on the controller.
   • Do not exceed the maximum rated current for the load output (20A).
5. التحقق من الاتصالات: Double-check all connections for correct polarity and tightness before proceeding.

7. تعليمات التشغيل

7.1. Automatic System Voltagه الاعتراف

The controller automatically detects whether the connected battery bank is 12V or 24V upon initial connection. Ensure the battery is connected first for proper voltagالكشف الإلكتروني.

7.2. طرق الشحن

The MP3752 employs intelligent PWM charging, automatically cycling through different stages to optimize battery health and lifespan:

• الشحن بالجملة: Delivers maximum current to rapidly bring the battery to approximately 80% charge.
• Equalise Charge: يطبق بشكل دوري حجمًا أعلىtage to equalize the charge among battery cells, preventing sulfation and extending battery life (for flooded batteries).
• تعويم المسؤول: يحافظ على شحن البطارية بالكامل من خلال توفير جهد صغير وثابتtagهـ، تعويضاً عن التسريح الذاتي.

7.3. Load Control

The load output is controlled by the controller to prevent over-discharge of the battery. When the battery voltagه يسقط أقل من Low Voltage Disconnect (LVD) threshold, the load output will be automatically disconnected. It will reconnect once the battery has recharged to the Low Voltage Reconnect (LVR) threshold.

Press the power button on the controller to manually turn the load output ON or OFF.

7.4. منفذ شحن USB

The 5V, 1.2A USB port can be used to charge small electronic devices like smartphones or tablets. This port is active as long as the battery has sufficient charge.
