6. Тохиргоо ба суурилуулалт

Нарны цэнэг хянагчийг зөв суурилуулахын тулд дараах алхмуудыг дагана уу.

1. Суурилуулалт: Choose a dry, well-ventilated indoor location, away from direct sunlight, high temperatures, and moisture. Ensure sufficient air circulation around the controller.
2. Зайны холболт:
   • 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. Нарны хавтангийн холболт:
   • 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. Холболтыг ачаалах:
   • 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. Холболтуудыг баталгаажуулах: Double-check all connections for correct polarity and tightness before proceeding.

7. Ашиглалтын заавар

7.1. Automatic System Voltage Хүлээн зөвшөөрөх

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 илрүүлэх.

7.2. Цэнэглэх горимууд

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

• Бөөнөөр төлөх төлбөр: 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).
