2. Safety Precautions

Please read all safety instructions carefully before installation and operation to prevent personal injury or damage to the controller and connected equipment.

• Ensure all wiring is correctly polarized and securely connected to prevent short circuits.
• Always connect the battery first, then the solar panels, and finally the load. Disconnect in the reverse order.
• Do not attempt to disassemble or repair the controller yourself. Refer to qualified personnel for service.
• Install the controller in a well-ventilated area, away from flammable materials and direct sunlight.
• Verify that the system voltage (12V/24V) matches the controller's auto-detection capabilities.
• This controller is designed for specific battery types (lead-acid, lithium iron phosphate, ternary lithium, water battery, colloidal battery). Ensure your battery type is compatible.

5. Installation Guide

5.1 Wiring Diagram

Follow the wiring sequence strictly to prevent damage to the controller. Connect the components in the order listed below:

1. Connect the Battery: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. The controller will automatically detect the system voltage (12V or 24V).
2. Connect Solar Panels: Connect the positive and negative terminals of your solar panels to the corresponding solar panel terminals on the controller.
3. Connect DC Load (Optional): Connect your DC load to the load terminals on the controller.
4. Connect Inverter (Optional): If using an inverter, connect it to the battery terminals (not directly to the controller's load terminals).

6. Operating Instructions

6.1 LCD Display Overview

The LCD display provides real-time information about your solar system. Familiarize yourself with the various indicators and buttons.

Figure 6.1: Key descriptions for the LCD display, showing the LCD screen, home page, turn on/off buttons, next turn button, and dual USB ports.

Figure 6.2: Detailed breakdown of LCD display elements including digital display area, voltage symbol, hours, current symbol, load identification, time, output identification, 5 battery level labels, charging logo (steady on for fast charge, slow flash for float charge), and button functions (MENU, UP, DOWN).

6.2 Parameter Settings

The controller allows for customization of various parameters to optimize performance for your specific setup. Use the MENU, UP, and DOWN buttons to navigate and adjust settings.

Figure 6.3: Flowchart of parameter settings, including browsing interface, setting parameters, float charging voltage, discharge recovery voltage, discharge cut-off voltage, load mode, battery type, operating display, operating temperature display, working charging current display, and working discharge current display. The battery has memory function after setting.

Adjusting Parameters:

1. Enter Parameter Setting: From the main interface, long press the MENU button for 3-5 seconds to enter the parameter setting mode. The number on the display will flash.
2. Navigate Parameters: Short press the MENU button to cycle through different parameters (e.g., floating charge voltage, discharge recovery voltage, discharge cut-off voltage, battery type, load working mode).
3. Adjust Value: While a parameter is flashing, use the UP (+) or DOWN (-) buttons to adjust the value to your desired setting.
4. Save and Exit: After adjusting a value, short press the MENU button again to save the setting and move to the next parameter. To exit the parameter setting mode, long press the MENU button for 3-5 seconds.

Key Parameters:

• Floating Charge Voltage: The voltage at which the battery is maintained after being fully charged to prevent overcharging.
• Discharge Recovery Voltage: The voltage at which the load will automatically reconnect after being disconnected due to low battery.
• Discharge Cut-off Voltage: The voltage at which the load will be disconnected to protect the battery from over-discharge.
• Battery Type (B01, B02, B03): Select the correct battery type for optimal charging. B01 is ternary lithium, B02 is lead acid, B03 is water battery or colloidal battery.
• Load Working Mode (CoE, AuEO, 00.00, OUE):
  • CoE: Manual mode (load controlled by ON/OFF button).
  • AuEO: Automatic optical control mode (load turns on/off based on light).
  • 00.00: Optical control delay mode (load turns on/off based on light with a set delay).
  • OUE: Normally open mode (load is always on).
• System Voltage Setting (bt12, bt24, bt60): This parameter allows you to manually force the system voltage, which can prevent charging/overcharging issues due to identification errors.

7. Maintenance

• Regularly check all wire connections for tightness and corrosion.
• Keep the controller clean and free from dust and debris. Use a dry cloth for cleaning.
• Ensure adequate ventilation around the controller to prevent overheating.
• Monitor the LCD display for any error codes or unusual readings.
