2. Kabelverbindungen
Connect the components in the following order to ensure safety and proper operation:
- Batterieanschluss: 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.
- Anschluss des Solarmoduls: Connect the solar panels to the controller's PV input terminals. Observe correct polarity. The maximum PV input voltage is 100V VOC.
- Lastanschluss: Schließen Sie Ihre Gleichstromverbraucher an die Lastausgangsklemmen des Controllers an.
- USB-Ausgang: Two 5V/3A USB ports are available for charging small electronic devices.
- 12-V-DC-Ausgang: A dedicated 12V DC output port is available for specific 12V loads.
Wichtig: Always connect the battery first, then the solar panels, and finally the load. Disconnect in the reverse order.
