4.2 Instruccions de cablejat
Connect the components in the following order to ensure safety and proper operation:
- Connecteu la bateria: Connect the battery to the controller's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The controller will automatically detect the system voltage (12V o 24V).
- Connecteu el panell solar: Connect the solar panel to the controller's solar panel terminals. Ensure correct polarity.
- Connecteu la càrrega de CC (opcional): If using a DC load directly from the controller, connect it to the load terminals.
Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order.

4.3 Muntatge
Mount the controller vertically on a flat surface using the provided mounting screws. Ensure adequate airflow around the unit for optimal heat dissipation.
5. Funcionament
The controller features an LCD display and four buttons for easy operation and monitoring.
5.1 Pantalla LCD acabadaview
The LCD displays various system parameters and operational status. Refer to the diagram below for an explanation of the display elements.
Imatge 5.1: Detallada view of the LCD display showing battery percentage, solar panel charging status, discharge indication, load indication, parameter display, setting, load timing indication, fault indication, battery type, and system voltage.
5.2 Funcions dels botons
The four buttons (ESC, Up, Down, SET) are used for navigation and parameter adjustment.
- Botó ESC: Used to switch the load (manual control) and exit setup menus.
- Botó amunt: Navigates up through main interface pages to view parameters; increases values in setting mode.
- Botó avall: Navigates down through main interface pages to view parameters; decreases values in setting mode.
- Botó SET: Enters setting mode, confirms selections, and saves changes. If no key operation occurs for 10 seconds in setting mode, it will automatically exit without saving.
5.3 Parameter Setting Stage
Per ajustar els paràmetres:
- Press the "ESC" button until the desired value flashes.
- Press the "Up" or "Down" button to adjust the value.
- Press the "SET" button to confirm and save the new value.
5.4 modes de treball
The controller supports three primary working modes for load control:
- Lighting Time Control Mode (1H-23H): Automatically turns the load on or off based on sunlight intensity and a set timer.
- Normal Off Mode (0H): The load remains off. This mode is useful for specific loads or during system debugging.
- Normal ON Mode (24H): The load remains continuously on. This mode is suitable for loads requiring a 24-hour power supply.
