POWERTECH MP3752 12V/24V 20A Соларни контролер - упутство за употребу

Model: MP3752 (03617080) | Brand: Jaycar

1. Увод

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).

2. Безбедносне информације

6. Подешавање и инсталација

Пратите ове кораке за правилну инсталацију вашег соларног регулатора пуњења:

  1. Монтажа: Choose a dry, well-ventilated indoor location, away from direct sunlight, high temperatures, and moisture. Ensure sufficient air circulation around the controller.
  2. Повезивање батерије:
    • 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. Повезивање соларне плоче:
    • 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. Учитавање везе:
    • 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. Проверите везе: Double-check all connections for correct polarity and tightness before proceeding.

7. Упутство за употребу

7.1. Automatic System Voltagе Препознавање

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

7.2. Режими пуњења

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

7.3. Load Control

The load output is controlled by the controller to prevent over-discharge of the battery. When the battery voltagе пада испод Лов Волtage 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. УСБ порт за пуњење

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.

8. Индикатори

The POWERTECH MP3752 features several LED indicators to provide real-time status information:

9. Одржавање

To ensure optimal performance and longevity of your solar charge controller, regular maintenance is recommended:

КСНУМКС. Решавање проблема

ПроблемМогући узрокРешење
No charging from solar panel.
  • No sunlight or insufficient light.
  • Solar panel or controller wiring incorrect/loose.
  • Solar panel damaged.
  • Батерија потпуно напуњена.
  • Wait for sufficient sunlight.
  • Check all solar panel connections for correct polarity and tightness.
  • Test solar panel output voltage.
  • This is normal if battery is full.
Load output not working.
  • Баттери волtage too low (LVD activated).
  • Load current too high (Over Load activated).
  • Short-circuit on load output.
  • Load output manually turned off.
  • Load device faulty.
  • Charge battery. Load will reconnect when voltagе се опоравља.
  • Reduce load or check for faulty load device.
  • Check load wiring for short-circuits.
  • Press the load button to turn it ON.
  • Test the load device independently.
Оверволtagе индикатор је укључен.
  • Solar panel open-circuit voltagе превисоко.
  • Баттери волtagе превисоко.
  • Уверите се да соларни панел волtage is within controller's limits.
  • Check battery health and ensure it's the correct voltagе за систем.
