2. Safety Information

Please read all safety instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Ensure all power sources (wind turbine, solar panels, battery) are disconnected before wiring or servicing the controller.
• Use appropriate personal protective equipment (PPE) such as insulated gloves and eye protection.
• All wiring must comply with local electrical codes and regulations.
• Do not disassemble or attempt to repair the controller. Refer to qualified service personnel.
• Install the controller in a well-ventilated area, away from flammable materials and direct sunlight.
• Ensure proper grounding of the system.
• Verify correct polarity for all connections to prevent damage to the controller and connected devices.

5. Setup and Installation

Proper installation is crucial for the safe and efficient operation of the hybrid charge controller. Follow the wiring diagram carefully.

5.1. Installation Location

• Choose a dry, well-ventilated location, protected from direct sunlight, rain, and excessive dust.
• Ensure sufficient clearance around the controller for heat dissipation.
• Mount the controller vertically on a non-flammable surface.

5.2. Wiring Sequence

Always connect components in the following order to prevent damage:

1. Connect the Battery: Connect the positive (B+) and negative (B-) terminals of the battery bank to the corresponding battery terminals on the controller. Ensure correct polarity. The controller will automatically detect the system voltage (12V or 24V).
2. Connect the Dump Load: Connect the external dump load resistor to the dedicated dump load terminals on the controller. This resistor is essential for dissipating excess energy from the wind turbine.
3. Connect the Wind Turbine: Connect the three-phase AC output wires of your wind turbine to the W1, W2, W3 terminals.
4. Connect the Solar Panels: Connect the positive (S+) and negative (S-) wires from your solar panel array to the solar panel terminals on the controller. Ensure correct polarity.
5. Connect the DC Load (Optional): If using, connect your DC loads to the L1+, L1-, L2+, L2- terminals. Ensure the total load does not exceed the controller's rated DC load capacity.

After all connections are made, double-check all polarities and connections before powering on the system. Incorrect wiring can cause severe damage to the controller and connected components.

6. Operating Instructions

The controller's LCD display and four-button interface allow for easy monitoring and parameter adjustment.

6.1. LCD Display Navigation

The LCD cycles through various screens displaying real-time data. Use the UP/DOWN buttons to manually cycle through screens or the SETTING button to enter parameter adjustment mode.

• Main Screen: Displays battery voltage, wind power, solar power, and charge status.
• Float Voltage (Vfloat): Shows the battery float charge voltage setting.
• Over Voltage (Vover): Indicates the over-charge protection voltage.
• No Braking (V no braking): Displays the voltage threshold for wind turbine braking.
• Time Setting: Allows adjustment of load control timing (if enabled).

6.2. Parameter Settings

To adjust parameters:

1. Press the SETTING button to enter the parameter setting mode. The first adjustable parameter will blink.
2. Use the UP and DOWN buttons to adjust the value.
3. Press SETTING again to confirm the value and move to the next parameter.
4. Press Esc to exit the setting mode at any time.

Refer to the specific parameters in the controller's menu for detailed descriptions and recommended values based on your battery type and system requirements.

6.3. Load Control Modes

The controller supports various DC load working modes, including light control and time control functions. These can be configured via the setting menu to automate the turning on/off of connected DC loads based on ambient light or a set schedule.

7. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your MarsRock Hybrid Charge Controller.

• Check Connections: Periodically inspect all wiring connections for tightness and corrosion. Loose connections can cause overheating and poor performance.
• Clean Controller: Keep the controller clean and free of dust and debris. Use a soft, dry cloth. Do not use liquid cleaners. Ensure ventilation openings are not blocked.
• Battery Inspection: Regularly check battery terminals for corrosion and ensure battery fluid levels (for flooded lead-acid batteries) are adequate.
• System Monitoring: Monitor the LCD display regularly for any unusual readings or error codes.
• Environmental Check: Ensure the installation environment remains within the specified temperature and humidity ranges.
