4.2 Wiring Diagram

Follow the wiring sequence below to ensure proper and safe operation. Incorrect wiring can damage the controller or other components.

1. Connect the battery to the controller's battery terminals (BATT+ and BATT-). Ensure correct polarity.
2. Connect the solar panels to the controller's PV input terminals (PV+ and PV-). Ensure correct polarity.
3. (Optional) Connect the DC load to the controller's load terminals (LOAD+ and LOAD-). Ensure correct polarity.

5. Operating Instructions

The MPPT controller features an intuitive LCD display and four function keys for monitoring and parameter adjustment.

5.1 LCD Display Overview

The LCD display provides real-time information about the system status, including battery voltage, charging current, and various settings. The display cycles through different screens to show comprehensive data.

5.2 Function Keys

The controller has four buttons: ESC, UP, DOWN, and ENTER. These buttons are used to navigate menus, adjust values, and confirm settings.

Figure 9: Table detailing the function of each key (ESC, UP, DOWN, ENTER) in setting mode, including short press and long press operations.

• ESC (PRG/ESC key): Short press to set/exit. In setting mode, short press to exit without saving data.
• UP (UP key): Short press to increase value or navigate to the previous setting page.
• DOWN (DOWN key): Short press to decrease value or navigate to the next setting page.
• ENTER (ENTER key): Short press to enter the next setting page. Long press to exit from setting and save the present settings data.

5.3 Battery Parameter Settings

The controller supports various battery types. It is crucial to set the correct battery parameters for optimal charging and battery longevity. The controller automatically multiplies parameters for higher voltage systems (e.g., 24V, 36V, 48V) based on the 12V reference values.

Figure 10: Reference table for 12V battery charging voltages (EQU, BST, FLD, BST_R, LRV, LDV) for different battery types (GEL, SEL, FLD, USE, LI).

Kindly Note:

• Please set according to the 12V battery parameters in the table above, and the controller program will automatically multiply the relative multiples.
• For example, for 24V lithium battery parameter setting, first select lithium battery mode, select 24V battery system, and then set BOOST Voltage to 14.2V, save and exit the settings.
• If the battery is lead-acid (AGM/GEL/FLD), it is not necessary to set the battery parameters.
• The BST (boost voltage) can only be modified if the battery type is set to "USE" or "LI". "---" means it cannot be modified.

6. Maintenance

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

• Cleaning: Periodically clean the exterior of the controller with a dry cloth to remove dust and debris. Ensure the cooling fan vents are clear of obstructions.
• Connections: Check all wiring connections regularly to ensure they are tight and free from corrosion. Loose connections can lead to power loss or overheating.
• Ventilation: Ensure the installation area provides adequate airflow for proper heat dissipation. The intelligent cooling fan requires clear space to operate effectively.
• Battery Health: Monitor your battery's health and voltage regularly. Ensure battery parameters are correctly set in the controller for the specific battery type in use.
