4. Sicherheitshinweise
Bitte beachten Sie bei der Installation und dem Betrieb die folgenden Sicherheitsvorkehrungen:
- Stellen Sie sicher, dass alle Verbindungen korrekt und sicher sind, bevor Sie das System einschalten.
- Connect the battery first, then the solar panel, and finally the DC load. Disconnect in the reverse order.
- Schließen Sie das Solarpanel nicht an den Laderegler an, wenn keine Batterie angeschlossen ist.
- Installieren Sie den Controller an einem gut belüfteten Ort, fern von direkter Sonneneinstrahlung, hohen Temperaturen und Feuchtigkeit.
- Verwenden Sie für alle Verbindungen geeignete Drahtquerschnitte, um Überhitzung und Leistungsverlust zu vermeiden.
- Dieses Gerät ist nur für den Innenbereich bestimmt.
- Außerhalb der Reichweite von Kindern aufbewahren.
5. Einrichtung und Installation
5.1 Montage des Controllers
Mount the solar charge controller vertically on a flat, non-flammable surface. Ensure there is adequate airflow around the unit for proper heat dissipation. Avoid mounting near flammable materials or in areas with excessive dust or moisture.
5.2 Kabelverbindungen
Follow the connection order carefully to prevent damage to the controller or other components. Always connect the battery first, then the solar panel, and finally the DC load.
- Schließen Sie die Batterie an: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. Ensure correct polarity. The controller will automatically detect the system voltage (12 V oder 24 V).
- Schließen Sie das Solarpanel an: Connect the positive and negative terminals of the solar panel to the corresponding solar panel terminals on the controller. Ensure correct polarity.
- Gleichstromlast anschließen: Connect the positive and negative terminals of your DC load to the corresponding load terminals on the controller. Ensure correct polarity.
Important: Disconnect components in the reverse order: Load, then Solar Panel, then Battery.
