2. Ledningsforbindelser
Tilslut komponenterne i følgende rækkefølge for at sikre sikkerhed og korrekt drift:
- Batteriforbindelse: Connect the battery to the controller's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The controller will auto-recognize 12V or 24V systems.
- Solpaneltilslutning: Connect the solar panels to the controller's PV input terminals. Observe correct polarity. The maximum PV input voltage is 100V VOC.
- Belastningsforbindelse: Tilslut dine DC-belastninger til controllerens belastningsudgangsterminaler.
- USB-udgang: Two 5V/3A USB ports are available for charging small electronic devices.
- 12V DC udgang: A dedicated 12V DC output port is available for specific 12V loads.
Vigtig: Tilslut altid batteriet først, derefter solpanelerne og til sidst belastningen. Frakobl i omvendt rækkefølge.
