7. Дастурҳои истифодабарӣ
7.1. Automatic System Voltage Эътироф
The controller automatically detects whether the connected battery bank is 12V or 24V upon initial connection. Ensure the battery is connected first for proper voltagд ошкор.
7.2. Усулҳои пуркунии барқ
The MP3752 employs intelligent PWM charging, automatically cycling through different stages to optimize battery health and lifespan:
- Нархи яклухт: 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).
- Нархи шиновар: Maintains the battery at a full charge by providing a small, constant voltage, compensating for self-discharge.
7.3. Load Control
The load output is controlled by the controller to prevent over-discharge of the battery. When the battery voltage поёнтар аз Ҳаҷми паст меафтадtage 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. Порт пуркунии USB
