• USB порт: 5V, 1.2A max output for charging small electronic devices.

6. Орнотуу жана орнотуу

Follow these steps for proper installation of your solar charge controller:

1. Монтаждоо: Choose a dry, well-ventilated indoor location, away from direct sunlight, high temperatures, and moisture. Ensure sufficient air circulation around the controller.
2. Батарея туташуу:
   • 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. Күн панелинин туташуу:
   • 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. Туташуу жүктөө:
   • 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. Байланыштарды текшерүү: Double-check all connections for correct polarity and tightness before proceeding.

7. Иштөө нускамалары

7.1. Automatic System Voltage Recognition

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

7.2. Заряддоо режимдери

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

• Жапырт акы: Delivers maximum current to rapidly bring the battery to approximately 80% charge.
• Equalise Charge: Periodically applies a higher voltage to equalize the charge among battery cells, preventing sulfation and extending battery life (for flooded batteries).
• Float акысы: Maintains the battery at a full charge by providing a small, constant voltage, өзүн-өзү бошотуу үчүн компенсация.

7.3. Load Control

The load output is controlled by the controller to prevent over-discharge of the battery. When the battery voltage Төмөн Төмөндө төмөндөйтtage 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.
