2. Sikkerhedsinstruktioner

Please read all instructions and warnings carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or serious injury.

• Ensure all connections are tight and correct to avoid excessive heat buildup.
• Tilslut altid batteriet til laderegulatoren først, derefter solpanelet og til sidst belastningen. Frakobl i omvendt rækkefølge.
• Forsøg ikke at reparere eller modificere styreenheden. Overlad al service til kvalificeret personale.
• Install the controller in a well-ventilated area, away from flammable gases and liquids.
• Brug øjenbeskyttelse, når du arbejder med batterier.
• Ensure the solar panel's open-circuit voltage (Voc) overstiger ikke regulatorens maksimale indgangsvolumentage.

4. Opsætning og installation

Follow these steps carefully to install your UNISOLAR 20.24 DR charge controller.

1. Montering: Choose a dry, well-ventilated location, protected from direct sunlight and moisture. Mount the controller vertically on a non-flammable surface, ensuring adequate airflow around the unit.
2. Forberedelse af ledning: Use appropriate wire gauges for your system's current and distance. Strip approximately 8-10mm of insulation from the wire ends.
3. Batteriforbindelse: Connect the battery wires to the battery terminals on the controller (marked with a battery symbol). Ensure correct polarity: positive to positive (+), negative to negative (-). This is the first connection to make.
4. Solpaneltilslutning: Connect the solar panel wires to the solar panel terminals on the controller (marked with a solar panel symbol). Ensure correct polarity.
5. Belastningsforbindelse (valgfrit): If using the controller's load output, connect your DC load wires to the load terminals (marked with a light bulb symbol). Ensure correct polarity.
6. Bekræft forbindelser: Double-check all connections for tightness and correct polarity before proceeding.

5. Betjeningsvejledning

Once installed, the UNISOLAR 20.24 DR will automatically begin operating. The LCD display provides real-time information about your system.

LCD-skærmoplysninger:

• Batteri Voltage: Viser den aktuelle voltage af din batteribank.
• Ladestrøm: Shows the current flowing from the solar panels to the battery.
• Belastningsstrøm: Indicates the current being drawn by the connected DC loads.
• Battery State of Charge (SOC): Often represented by a battery icon with varying fill levels.
• System Status Icons: Icons may indicate solar charging, load on/off, and fault conditions.

Belastningskontrol:

The controller may feature a button or menu option to manually turn the DC load output on or off. Consult the on-screen prompts or specific product documentation for detailed load control settings, such as timer functions.

6. Vedligeholdelse

Regelmæssig vedligeholdelse sikrer optimal ydeevne og levetid for din solcelleladeregulator.

• Tjek forbindelser: Kontrollér regelmæssigt alle ledningsforbindelser for tæthed og korrosion. Løse forbindelser kan forårsage overophedning og skader.
• Rengør controlleren: Keep the controller clean and free of dust. Use a dry cloth to wipe the casing. Do not use liquids or solvents.
• Undersøg ledninger: Check for any signs of wear, fraying, or damage to the insulation of all cables connected to the controller.
• Ventilation: Ensure the area around the controller remains clear for proper ventilation.
