Key Features:

• Automatic identification and combination of 12V, 24V, 48V batteries.
• Wind turbine charging with boost MPPT control algorithm for efficient charging even at low wind speeds.
• Stepless discharge function with external unloading resistor.
• Solar panel charging using PWM technology via series MOS tubes.
• Compatibility with various battery types, with adjustable parameters.
• Large LCD screen for clear display of operational parameters.
• Multiple protection features: solar reverse connection, overcharge, undervoltage, overload, battery reverse connection, open circuit, and lightning protection.
• Adjustable output modes.

2. Safety Instructions

• Do not plug or unplug the power adapter with wet hands. This can lead to electric shock.
• Always pay close attention to connection methods and polarity during installation to prevent damage to the controller or other components.
• Ensure proper ventilation around the controller to prevent overheating.
• The internal circuit board is coated with three-proof paint for protection against dust, moisture, and static electricity. However, avoid exposing the controller to excessive moisture or extreme environmental conditions.
• Only qualified personnel should perform installation and maintenance.

It shows connections for the wind turbine (Fan), solar panel array (PV Array), storage battery, and electrical load. It also indicates the RS485 communication port and the external unloading resistor. Ensure all connections follow this diagram for correct functionality.

4.2 Installation Steps:

1. Mount the Controller: Choose a dry, well-ventilated location for mounting the controller. Ensure it is protected from direct sunlight and moisture.
2. Connect the Battery: Connect the battery to the controller's battery terminals (B+ and B-). Ensure correct polarity. The controller will power on once the battery is connected.
3. Connect the Wind Turbine: Connect the wind turbine's output wires to the fan wiring terminals (S+ and S-).
4. Connect the Solar Panels: Connect the solar panel array to the solar panel terminals (S+ and S-). Ensure correct polarity.
5. Connect the Unloading Resistor: Connect the external unloading resistor to the designated unloading terminals. This is crucial for the stepless discharge function.
6. Connect the Load: Connect your DC loads to the load terminals (L1+ and L1-).
7. Verify Connections: Double-check all wiring for correct polarity and secure connections before proceeding.

5. Operating Instructions

The controller features an LCD display and intuitive buttons for easy operation and monitoring.

5.1 LCD Display and Buttons:

• LCD Display: Shows real-time system parameters such as voltage, battery power, current, power, load mode, and temperature.
• "Enter" Key: Used to enter the main menu and save parameter settings.
• "Up" Key: Used to navigate through display parameters or increase values during settings.
• "Down" Key: Used to navigate through display parameters or decrease values during settings.
• "Esc" Key: Used to exit the setting interface.
• Charging Indicator: Indicates charging status (Off: no charging, Long Light: charging).
• Output Indicator: Indicates load output status (Off: output off, Long Light: output is normal).

5.2 Setting Operating Modes:

The controller supports multiple load output working modes:

• Pure Light Control Mode: Load output is controlled solely by ambient light levels.
• Normally Open Mode: Load output is continuously active.
• Light Control + Time Control Mode: Combines ambient light sensing with programmable time periods (four periods + morning light) for load control.

Refer to the on-screen menu using the "Enter", "Up", "Down", and "Esc" keys to configure these modes and other parameters like battery type.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your hybrid charge controller.

• Visual Inspection: Periodically inspect all wiring connections for tightness and signs of corrosion or damage.
• Cleanliness: Keep the controller clean and free from dust and debris. The internal circuit board has a three-proof paint coating, but external cleanliness is still important.
• Ventilation: Ensure that the heat dissipation fins are not obstructed to allow for proper airflow and self-cooling.
• Parameter Check: Occasionally check the parameters displayed on the LCD to ensure the system is operating within expected ranges.
