POWERTECH MP3752 12V/24V 20A Solar Controller User Manual

1. ആമുഖം

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).

6. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും

നിങ്ങളുടെ സോളാർ ചാർജ് കൺട്രോളർ ശരിയായി ഇൻസ്റ്റാൾ ചെയ്യുന്നതിന് ഈ ഘട്ടങ്ങൾ പാലിക്കുക:

1. മൗണ്ടിംഗ്: Choose a dry, well-ventilated indoor location, away from direct sunlight, high temperatures, and moisture. Ensure sufficient air circulation around the controller.
2. ബാറ്ററി കണക്ഷൻ:
   • 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. സോളാർ പാനൽ കണക്ഷൻ:
   • 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. ലോഡ് കണക്ഷൻ:
   • 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. കണക്ഷനുകൾ പരിശോധിക്കുക: Double-check all connections for correct polarity and tightness before proceeding.

7. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

7.1. Automatic System Voltagഇ അംഗീകാരം

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

7.2. ചാർജിംഗ് മോഡുകൾ

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

• ബൾക്ക് ചാർജ്: 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).
• ഫ്ലോട്ട് ചാർജ്: Maintains the battery at a full charge by providing a small, constant voltage, compensating for self-discharge.

7.3. ലോഡ് നിയന്ത്രണം

The load output is controlled by the controller to prevent over-discharge of the battery. When the battery voltagഇ താഴ്ന്ന വോള്യത്തിന് താഴെയായി കുറയുന്നുtage 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. യുഎസ്ബി ചാർജിംഗ് പോർട്ട്

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.
