4.1. Wiring Connection Diagram

Figure 4: Wiring Connection Diagram

1. Mounting: Mount the controller vertically on a flat, non-flammable surface, ensuring adequate ventilation around the unit. Use the provided hang brackets.
2. Battery Connection: Connect the battery to the controller's battery terminals first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the battery voltage.
3. Solar Panel Connection: Connect the solar panels to the controller's solar panel terminals. Ensure correct polarity. The controller supports up to 150V PV input.
4. DC Load Connection (Optional): Connect your DC loads to the DC load terminals. This output is controlled by the controller and can be programmed for various operating modes.
5. Temperature Sensor: Connect the external temperature sensor to the designated port (8). This ensures accurate temperature compensation for battery charging.
6. RS485 Communication: If using remote monitoring, connect the RS485 communication cable to the port (12).

Wiring Order is Crucial: Always connect the battery first, then solar panels, then DC load. Disconnect in reverse order.

5. Operating Instructions

The LCD display provides real-time system information, and the four buttons (Menu, Down, Up, Enter) allow for navigation and parameter adjustment.

5.1. Display Navigation

Press the MENU button to cycle through different display screens showing various system parameters such as PV voltage, charging current, battery voltage, daily and total energy generated, and load status.

5.2. Parameter Settings

To enter the parameter setting mode, press and hold the ENTER button for a few seconds. Use the UP and DOWN buttons to navigate through the settings, and ENTER to select or confirm changes. The default password for accessing settings is usually a sequence of arrow presses (e.g., Down, Down, Down, Up, Up, Up), refer to the specific manual for the exact sequence.

• Battery Type Setting: Select the appropriate battery type (Sealed, Gel, Flooded, Lithium, or User-defined) to ensure optimal charging algorithms.
• Charge Voltage Settings: Adjust parameters like Floating Charge Voltage, Equalization Charge Voltage, and Over-discharge Protection Voltage based on your battery manufacturer's recommendations, especially for user-defined battery types.
• Load Control Mode: Configure the DC load output to operate in various modes (e.g., always on, light control, timer control).
