• Accessible for maintenance but secure from unauthorized access.
• Close to the battery bank and main electrical panel to minimize cable length.

4.3 Wiring Connections

All wiring must comply with local electrical codes and standards. Ensure all connections are tight and secure.

1. Battery Connection: Connect the battery terminals to the inverter's battery input terminals, ensuring correct polarity (positive to positive, negative to negative).
2. Solar Panel Connection: Connect the solar panel array to the inverter's solar input terminals. Verify the voltage and current ratings of the solar panels are within the inverter's specifications.
3. Mains Input Connection: Connect the AC mains supply to the inverter's mains input terminal.
4. Load Output Connection: Connect your home/office electrical loads to the inverter's AC output terminals.
5. Grounding: Ensure the inverter is properly grounded to prevent electrical hazards.

Note: Refer to the detailed wiring diagram provided in the separate installation guide for specific connection points.

5. Operating Instructions

5.1 Initial Power-Up

1. After all connections are securely made, switch on the battery breaker (if applicable).
2. Switch on the inverter's main power switch. The LCD display will illuminate, and the inverter will perform a self-test.
3. If connected to mains, the inverter will detect the mains supply and begin charging the battery (if needed).
4. If solar panels are connected and sunlight is available, the inverter will begin solar charging.

5.2 LCD Display Indicators

The LCD display provides critical information about the inverter's status:

• Mains On: Indicates that the inverter is receiving power from the utility grid.
• Solar Charging: Indicates that the battery is being charged by solar panels.
• Mains Charging: Indicates that the battery is being charged by the utility grid.
• Power Saver: Indicates the inverter is operating in power-saving mode.
• Battery Low: Warns that the battery charge is critically low.
• Over Load: Indicates that the connected load exceeds the inverter's capacity.
• System On: Indicates the inverter is operational and providing power.

5.3 Operating Modes

The Luminous NXG 1150 automatically switches between modes based on power availability and load requirements:

• Grid Mode: When mains power is available, the inverter charges the battery and passes mains power to the loads.
• Solar Mode: When solar power is sufficient, the inverter prioritizes solar energy to power loads and charge batteries.
• Battery Mode: During power outages or when solar power is insufficient, the inverter draws power from the battery to supply loads.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Luminous NXG 1150 Solar Inverter.

• Cleaning: Periodically clean the inverter's exterior with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. Do not use liquid cleaners.
• Connections: Annually check all electrical connections for tightness and corrosion. Loose connections can cause overheating and poor performance.
• Battery Maintenance: Follow the battery manufacturer's guidelines for maintenance, including checking electrolyte levels (for flooded batteries) and terminal cleaning.
• Ventilation: Ensure the area around the inverter remains clear to allow for adequate airflow.

Note: For any internal issues or complex repairs, contact authorized Luminous service personnel.
