4. Configuració i instal·lació

Una instal·lació correcta és crucial per al funcionament segur i eficient del vostre sistema de càrrega solar. Seguiu aquests passos amb atenció.

4.1 Wiring Sequence

1. Connecteu la bateria: Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -). The battery status LED indicator (⑦) should illuminate.
2. Connect the Load: Connect the DC load to the charge controller. Ensure correct polarity.
3. Connecteu el panell solar: Connect the solar panel (PV array) to the charge controller. Ensure correct polarity. The charging status LED indicator (⑨) should illuminate if there is sufficient solar input.

Important: Always connect the battery first and disconnect the solar panel first when disassembling the system. This sequence prevents damage to the controller.

4.2 Muntatge

• Mount the controller vertically on a wall or other solid surface.
• Ensure adequate air circulation around the controller for heat dissipation.
• Avoid mounting in direct sunlight, high temperature, or humid environments.
• The mounting hole size is Φ4.5mm.

4.3 Connexions de terminals

The LS1024EU controller uses 12AWG/4mm² terminals. Ensure all wire connections are tight to prevent voltaggotes de líquids i sobreescalfament.

5. Instruccions de funcionament

5.1 Indicadors LED

• Charging Status LED (⑨): Indicates the charging status from the solar panel to the battery.
• Battery Status LED (⑦): Shows the current battery voltage nivell.
• Load Status LED (⑧): Indicates the status of the connected DC load (ON/OFF, Overload, Short-circuit).

5.2 Selecció del tipus de bateria

The controller supports Sealed, Gel, and Flooded battery types. It is crucial to select the correct battery type for optimal charging and battery longevity.

1. Entra al mode de configuració: Press and hold the button (⑥) for 5 seconds until the battery status LEDs (⑦) start flashing.
2. Seleccioneu el mode desitjat: Press the button (⑥) repeatedly to cycle through the battery types (Sealed, Gel, Flooded). The flashing LEDs will indicate the selected type.
3. Desa la configuració: The selected mode will be saved automatically if no operation is performed for 5 seconds, and the LEDs will stop flashing.
