5. Installation
Korrekt installation er afgørende for sikker og effektiv drift af din solcelleladeregulator. Følg disse trin omhyggeligt:
5.1 Montering af controlleren
- Choose a suitable location: Ensure it is dry, well-ventilated, and protected from direct sunlight and moisture.
- Secure the controller to a wall or mounting surface using four screws.

5.2 Ledningsforbindelser
Vigtig: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order (load, then solar panel, then battery).
- Tilslut batteriet: Connect the positive and negative terminals of your battery to the corresponding battery terminals on the controller. Ensure correct polarity.
- Tilslut solpanelet: Connect the positive and negative terminals of your solar panel(s) to the corresponding PV input terminals on the controller. Ensure correct polarity.
- Tilslut DC-belastningen (valgfrit): If using a DC load directly from the controller, connect its positive and negative terminals to the load terminals on the controller.
- Tænd: Close the battery circuit breaker to power on the controller.

6. Betjening
The controller features an LCD display and three buttons for easy monitoring and parameter adjustment.
6.1 LCD-skærm og knapper
The LCD displays real-time system information such as solar panel voltage, batteri voltage, charging current, and load status. The three buttons (PV/A, BAT/V, SET/↓) are used for navigating menus and adjusting settings.
- PV/A Button: Short press to cycle through solar panel related displays (e.g., PV voltage, ladestrøm).
- BAT/V Button: Short press to cycle through battery related displays (e.g., battery voltage, battery type).
- SET/↓ Button: Short press to enter or exit setting mode, or to decrease a value during setting. Long press to save settings.
6.2 Indstilling af batteritype
To optimize charging, select the correct battery type:
- Tryk på BAT/V button until the battery type icon flashes on the LCD.
- Brug PV/A og SET/↓ buttons to cycle through available battery types (e.g., SEL for Sealed, FLD for Flooded, GEL for Gel, Li for Lithium).
- Once the desired battery type is displayed, long press the SET/↓ knappen for at bekræfte og gemme indstillingen.
The controller will automatically return to the default display screen if no button is pressed for 100 seconds.
