3. Sikkerhedsinstruktioner

Please observe all warnings and cautions in this manual. Improper operation may cause damage to the unit and/or personal injury. This device is intended for indoor use only. Do not expose it to rain, snow, or any type of liquid.

• Høj voltage Advarsel: Inverteren fungerer med høj lydstyrketages. All wiring must be performed by qualified personnel.
• Batterisikkerhed: Batteries can produce explosive gases. Ensure proper ventilation when working with batteries. Do not short-circuit battery terminals.
• Jording: The inverter must be properly grounded to prevent electric shock.
• Ventilation: Sørg for tilstrækkelig luftgennemstrømning omkring inverteren for at forhindre overophedning. Ventilationsåbningerne må ikke blokeres.
• Overvågning: This product should be used under the direct supervision of an adult.

• Batteriforbindelse: Connect the battery bank to the 'BATTERY POS' and 'BATTERY NEG' terminals. Ensure correct polarity.
• AC-indgangsforbindelse: Connect the utility grid or generator AC supply to the 'AC IN' terminal.
• AC-udgangstilslutning: Connect your loads (appliances, computers, etc.) to the 'AC OUT' terminal.
• PV-indgangsforbindelse: Connect your solar panel array to the 'PV IN' terminals. Observe correct polarity and voltage grænser.
• Kommunikationsporte: Use the RS232 or USB ports for monitoring and configuration with compatible software.

5. Driftstilstande

The inverter supports various operating modes, which can be configured via the LCD display. These modes determine the power source priority (utility, solar, or battery) for supplying power to the loads and charging the batteries.

Figure 5.1: Display illustrations showing four operating modes: 1. With battery, solar and AC available. 2. With battery, solar and AC not available. 3. Without battery, solar available. 4. Without battery, AC available. This image also shows a 'Pure Sine Wave 50/60 Hz Auto Detection' graphic.

• Utility Priority Mode: The inverter primarily uses utility power to supply loads and charge batteries. Solar power is used when utility power is unavailable or insufficient.
• Solar Priority Mode: Solar power is the primary source for loads and battery charging. Utility power is used only when solar power is insufficient or unavailable.
• Batteriprioritetstilstand: The inverter uses battery power as the primary source. Utility or solar power is used to charge batteries or when battery voltage er lav.
• Ingen batteritilstand: Certain models can operate without a battery, directly converting solar PV power to AC for loads, provided the PV voltage er over 250V.

6. Specifikationer

The following table provides detailed technical specifications for the WLLKIY Hybrid Solar Inverter models.

7. Fejlfinding

This section provides solutions to common issues you may encounter with your inverter. For problems not listed here, please contact customer support.

• Inverteren tænder ikke: Kontroller batteriforbindelser, sørg for batterispændingtage is within operating range, verify AC input connection if applicable, and check the input breaker.
• Ingen AC-udgang: Check for overload conditions, ensure the inverter is not in fault mode, verify AC output wiring, and check if the utility grid is present if in utility priority mode.
• Batteri oplades ikke: Bekræft solpanelforbindelser og volumentage, check AC input if AC charging is enabled, ensure charge settings are correct on the display.
• Overbelastningsalarm: Reduce the connected load. The inverter will automatically restart after a cool-down period if the overload is removed.

8. Vedligeholdelse

Regelmæssig vedligeholdelse sikrer din inverters levetid og optimale ydeevne.

• Rensning: Rengør inverterens yderside regelmæssigt med en tør klud. Sørg for, at ventilationsåbningerne er fri for støv og snavs.
• Tilslutningskontrol: Kontrollér årligt alle ledningsforbindelser for tæthed og tegn på korrosion.
• Batteriinspektion: If using lead-acid batteries, check electrolyte levels and terminal cleanliness regularly.
• Miljøtjek: Sørg for, at installationsmiljøet forbliver inden for de angivne temperatur- og fugtighedsintervaller.
