4.2 Ledningsforbindelser
Tilslut komponenterne i følgende rækkefølge for at undgå skader:
- Tilslut batteriet: Connect the battery to the controller's battery terminals. Ensure correct polarity (+ to + and - to -). The LCD display should light up.
- Tilslut solpanelet: Connect the solar panel to the controller's solar panel terminals. Ensure correct polarity. The controller will begin charging the battery.
- Tilslut belastningen (valgfrit): Tilslut din DC-belastning til controllerens belastningsterminaler. Sørg for korrekt polaritet.
Vigtig: Tilslut altid batteriet først, derefter solpanelet og til sidst belastningen. Frakobl i omvendt rækkefølge: belastning, derefter solpanelet og derefter batteriet.

5. Betjeningsvejledning
The controller features an LCD display and control buttons for easy operation and monitoring.
5.1 LCD-skærm og knapper
The LCD screen displays real-time system status, including battery voltage, charging current, load current, and various parameters. The buttons (SET, UP, DOWN, ESC) allow you to navigate menus and adjust settings.
Figure 5.1: Close-up of the LCD display and control buttons (SET, UP, DOWN, ESC).
5.2 Parameterindstillinger
Tryk på SÆT knappen for at åbne parameterindstillingsmenuen. Brug UP og NED buttons to navigate through different parameters (e.g., battery type, load control mode). Press SÆT again to confirm a selection or enter edit mode. Use UP/NED to change values, then SÆT at gemme. Trykke ESC to exit the menu without saving changes.
5.3 USB-udgang
The controller is equipped with dual 5V 3A USB ports. These ports can be used to charge compatible electronic devices directly from the controller.
6. Vedligeholdelse
Regular maintenance ensures optimal performance and extends the lifespan of your solar controller.
6.1 Rengøring
Periodically clean the controller's exterior with a dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation openings are free from dust and debris.
6.2 Varmeafledning
The controller features a dual fan system for efficient heat dissipation. Ensure that the fans are not obstructed and operate correctly. If the controller consistently runs hot, verify proper ventilation and ensure the solar panel power does not exceed the controller's rated current for extended periods.
