Sicherheitshinweise
- Ensure all connections are correct before powering on the controller. Incorrect wiring can damage the device or connected components.
- The controller is designed for indoor use or in a protected environment. Avoid exposure to direct sunlight, high temperatures, or moisture.
- Versuchen Sie nicht, den Controller selbst zu zerlegen oder zu reparieren. Wenden Sie sich für Reparaturen an qualifiziertes Fachpersonal.
- Außerhalb der Reichweite von Kindern aufbewahren.
- This controller is only suitable for lead-acid batteries: OPEN, AGM, GEL. Do not use with other battery types like Lithium-ion or LiFePO4, as this may cause damage or safety hazards.
- Always connect the battery first, then the solar panel, and finally the load. When disconnecting, reverse the order: disconnect the load, then the solar panel, and finally the battery.
Produkteigenschaften
- Automatisches System Voltage Identifizierung: Automatically detects 12V/24V system voltage.
- PWM-Ladung: Efficient Pulse Width Modulation charging mode.
- Dual USB Ports: Provides 5V/2A output for charging mobile devices.
- LCD Anzeige: Clear display of status and data, allowing for convenient mode switching and parameter configuration.
- Mehrere Schutzfunktionen: Includes short-circuit protection, open-circuit protection, reverse protection, and over-load protection.
- Einstellbare Parameter: User-adjustable charge and discharge parameters.
- Temperaturkompensation: Automatische Temperaturkompensation für optimales Laden.
Setup und Installation
Follow these steps carefully to install your solar charge controller. Incorrect installation can lead to damage or malfunction.
- Verkabelung vorbereiten: Ensure all wires are properly stripped and have appropriate connectors if necessary. Use wires of sufficient gauge for your system's current.
- Schließen Sie die Batterie an: Connect the battery to the charge regulator first. Observe correct polarity (+ to + and - to -). The controller will automatically recognize the battery voltage (12 V oder 24 V).
