Manual de utilizare pentru controlerul solar POWERTECH MP3752 12V/24V 20A

1. Introducere

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).

Borne de conectare:

• Solar Panel Input (PV): Connect your solar panel array here. Ensure correct polarity (+ and -).
• Conexiune baterie: Connect your 12V or 24V battery bank here. Observe correct polarity (+ and -).
• Ieșire sarcină: Connect your DC loads (e.g., lights, fans) here. Observe correct polarity (+ and -).
• Port USB: 5V, 1.2A max output for charging small electronic devices.

6. Configurare și instalare

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

1. Montare: Choose a dry, well-ventilated indoor location, away from direct sunlight, high temperatures, and moisture. Ensure sufficient air circulation around the controller.
2. Conexiune baterie:
   • 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. Conexiune panou solar:
   • 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. Conexiune de încărcare:
   • 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. Verificați conexiunile: Double-check all connections for correct polarity and tightness before proceeding.

7. Instrucțiuni de utilizare

7.1. Automatic System Voltage Recunoaștere

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 detectare.

7.2. Moduri de încărcare

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

• Încărcare în vrac: 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).
• Taxă plutitoare: Menține bateria la o încărcare completă prin furnizarea unui volum mic și constanttage, 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 scade sub volumul scăzuttage 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. Port de încărcare USB

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. Indicatori

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

• PV LOAD (Solar Panel Indicator):
  • Verde: Solar panel is connected and generating power.
  • Off: No solar input or insufficient light.
• Indicator de încărcare:
  • Verde: Bateria se încarcă.
  • Off: Battery is fully charged or not charging.
• Overvoltage Indicator:
  • Roşu: Vol. De intraretage from solar panel is too high, or battery voltage is overcharge protection level.
• UVW (Battery Voltage Indicator): Multiple LEDs indicating battery charge level.
• LVD (Vol. scăzuttage Disconnect Indicator):
  • Roşu: Volumul baterieitage is low, load output has been disconnected.
• Load ON Indicator:
  • Verde: Load output is active.
• Over Load Indicator:
  • Roşu: Load current exceeds the maximum rated current. Load output may be temporarily disconnected.
• Short-Circuit Indicator:
  • Roşu: Short-circuit detected on the load output. Load output will be disconnected.

9. Întreținere

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

• curatenie: Periodically clean the exterior of the controller with a dry, soft cloth. Do not use solvents or abrasive cleaners.
