3. Configuració i instal·lació

Proper installation is crucial for the safe and efficient operation of your solar system. Please follow these steps carefully.

3.1 Precaucions de seguretat

• Ensure all connections are tight and secure to prevent loose connections that can cause excessive heat.
• Install the controller in a well-ventilated area, away from direct sunlight and moisture.
• Connecteu sempre primer la bateria, després el panell solar i finalment la càrrega. Desconnecteu-ho en ordre invers.
• Use appropriate wire gauges for your system's current to avoid overheating.

3.2 Esquema de cablejat

Connect the components in the following order: 1. Battery, 2. Solar Panel, 3. DC Load (if applicable). Refer to the diagram below for correct wiring.

1. Connecteu la bateria: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the solar controller. The controller will automatically detect the battery voltage (12V o 24V).
2. Connecteu el panell solar: Connect the positive and negative terminals of the solar panel to the corresponding solar panel terminals on the controller.
3. Connecteu la càrrega de CC (opcional): Connect the positive and negative terminals of your DC load to the corresponding load terminals on the controller.

Important: Always ensure correct polarity when making connections. Incorrect polarity can damage the controller and other components.

4. Instruccions de funcionament

The Walfront Solar Controller features an intuitive LCD display and three buttons for easy navigation and parameter adjustment.

4.1 Informació de la pantalla LCD

The LCD screen displays various system parameters:

• Voltage (V): Current system voltage.
• Corrent (A): Charging or discharging current.
• Battery State of Charge (%): Visual representation of battery level.
• Solar Panel Charge Indicator: Shows when solar panels are charging the battery.
• Indicador de càrrega: Shows when the load is active.
• Hora: Indicates timer settings for the load.

4.2 Funcions dels botons

• Botó MENÚ: Press to cycle through display modes and enter/exit parameter setting mode.
• Botó amunt: Used to increase values or navigate upwards in menus.
• DOWN/ON/OFF Button: Used to decrease values, navigate downwards in menus, or toggle the DC load on/off (long press).

4.3 Configuració dels paràmetres

To adjust parameters such as discharge cut-off voltage or charging recovery voltage:

1. Manteniu premut el botó MENÚ button for a few seconds until the display starts flashing.
2. Utilitza el UP i ABAIX buttons to navigate through the different parameters.
3. Premeu el botó MENÚ button again to select a parameter for adjustment.
4. Utilitza el UP i ABAIX botons per canviar el valor.
5. Manteniu premut el botó MENÚ button again to save the changes and exit the setting mode.

The controller will remember user-set parameters even after battery depletion, eliminating the need for frequent resets.

4.4 Sortida USB

The two USB ports provide 5V 2.5A (maximum) output for charging compatible electronic devices. These ports are active when the controller is powered.

5. Manteniment

Un manteniment regular garanteix la longevitat i el rendiment òptim del vostre controlador solar.

• Inspeccionar connexions: Periodically check all wiring connections for tightness and corrosion. Loose connections can lead to power loss or overheating.
