2. Turn on the battery circuit breaker (if installed).
3. Turn on the main AC input circuit breaker.
4. Press the power button on the inverter to turn it on.
5. Observe the inverter display for status indicators and ensure normal operation.

5. Operating Instructions

5.1. Basic Operation

• Power On/Off: Press and hold the power button on the inverter for a few seconds to turn the system on or off.
• Mode Selection: The NXG+ 1625 typically operates in a solar priority mode, utilizing solar power first, then battery, and finally grid power. Refer to the inverter's display for current operating mode.

5.2. Monitoring System Status

The inverter's front panel display provides real-time information about the system's status:

• Battery Charge Level: Indicates the current charge status of the connected batteries.
• Load Level: Shows the percentage of connected load being powered by the inverter.
• Input Source: Displays whether the system is drawing power from solar, battery, or grid.
• Fault Indicators: Alerts for any system errors or warnings. Consult the troubleshooting section if a fault is indicated.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your Luminous NXG+ 1625 Inverter System.

6.1. Inverter Maintenance

• Keep the inverter clean and free from dust. Use a dry cloth for cleaning.
• Ensure ventilation openings are not blocked.
• Periodically check all wiring connections for tightness and signs of corrosion.

6.2. Battery Maintenance

• Water Level Check: For tall tubular batteries, regularly check the electrolyte level and top up with distilled water if necessary. Do not overfill.
• Keep battery terminals clean and free from corrosion. Apply petroleum jelly to terminals to prevent corrosion.
• Ensure batteries are kept in a well-ventilated area.

6.3. Solar Panel Maintenance

• Clean solar panels regularly to remove dust, dirt, and debris that can reduce efficiency. Use a soft cloth and water.
• Inspect panels for any physical damage or shading from trees or other obstructions.
