4.3 Installation Steps (Simplified)
- Mount Solar Panels: Securely mount the two 170W Polycrystalline solar panels on the chosen location, ensuring proper tilt and orientation for maximum sunlight exposure.
- Connect Solar Panels to Inverter: Connect the solar panel output cables to the designated solar input terminals on the Luminous NXG+1450 Hybrid Inverter. Ensure correct polarity.
- Connect Battery to Inverter: Connect the LPTT12150H 150Ah Tall Tubular Battery to the battery terminals on the inverter. Observe correct positive (+) and negative (-) connections.
- Connect Inverter to Grid: Connect the inverter's AC input to your main electrical grid supply.
- Connect Inverter to Loads: Connect your household appliances and electrical loads to the inverter's AC output.
- Grounding: Ensure all components, especially the inverter and solar panel frames, are properly grounded.
- Initial Power-Up: After all connections are secure and verified, switch on the battery breaker, then the solar breaker (if applicable), and finally the inverter. Follow the inverter's specific power-up sequence.
5. Operating Instructions
Your Luminous Solar Home Solution is designed for automatic operation, prioritizing solar power to reduce electricity bills.
5.1 Hybrid Operation
- The NXG+1450 Hybrid Inverter intelligently manages power flow from solar panels, battery, and grid.
- During daylight hours, solar energy powers your home and charges the battery. Any excess solar power can be fed back to the grid (if configured and allowed by local regulations).
- When solar power is insufficient or at night, the inverter draws power from the battery.
- If the battery charge is low, the system automatically switches to grid power to ensure continuous supply and recharge the battery.
- This system is designed to save approximately 3-4 units of electricity per day by maximizing solar utilization.
5.2 Inverter Display and Indicators
Familiarize yourself with the inverter's front panel indicators for system status:
- Solar Charging Indicator: Illuminates when solar panels are actively charging the battery.
- Mains On Indicator: Shows when grid power is available and connected.
- Battery Charging Indicator: Indicates battery charging status (from solar or grid).
- Inverter On Indicator: Confirms the inverter is active and supplying power.
- Overload Indicator: Warns of excessive load connected to the inverter.
- Battery Low Indicator: Alerts when battery charge is critically low.

6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your Luminous Solar Home Solution. This system is designed to be reliable and maintenance-friendly.
6.1 Solar Panels
- Cleaning: Periodically clean the surface of the solar panels to remove dust, dirt, and debris. Use a soft cloth and water. Avoid abrasive cleaners or harsh brushes.
- Inspection: Regularly inspect panels for any physical damage, cracks, or loose connections. Ensure no new shading sources have appeared.
- The 170W Polycrystalline panels are durable and weather-resistant.

6.2 Battery (LPTT12150H 150Ah Tall Tubular)
- Water Level Check: For tubular batteries, regularly check the electrolyte level and top up with distilled water if necessary. Do not overfill.
- Terminal Cleaning: Keep battery terminals clean and free from corrosion. Apply petroleum jelly to terminals to prevent corrosion.
- Ventilation: Ensure the battery area is well-ventilated to dissipate any gases produced during charging.
6.3 Inverter (NXG+1450 Hybrid)
- Dust Removal: Keep the inverter's ventilation openings clear of dust and obstructions. Use a soft brush or compressed air to clean.
- Connection Check: Periodically check all electrical connections for tightness and signs of wear or damage.
