4. Product Overview

The Luminous NXG+ 1625 system is an integrated solar power solution. Below is an image of the main components.

Figure 1: Luminous NXG+ 1625 Inverter, LPTT 12150H Battery, and 330W Solar Panel. This image displays the primary components of the solar power system, including the inverter unit, two batteries, and two solar panels.

4.1. Luminous NXG+ 1625 Inverter

The inverter converts DC power from the batteries and solar panels into AC power for your home appliances. It features a pure sine wave output for sensitive electronics and intelligent solar charge control.

4.2. Luminous LPTT 12150H Battery

These are deep cycle tubular batteries designed for long power backup duration and efficient charging from solar panels. Two batteries are included for increased capacity.

4.3. Luminous 330W Solar Panel

The two 330W solar panels capture sunlight and convert it into DC electricity, which is then used to charge the batteries and power the inverter.

5. Setup and Installation

Professional Installation Recommended: Due to the complexity and electrical hazards involved, it is strongly recommended that a certified Luminous technician or qualified electrician performs the installation.

5.1. Site Selection

• Inverter: Choose a dry, well-ventilated, and easily accessible location, away from direct sunlight and moisture. Ensure adequate clearance for air circulation.
• Batteries: Place batteries in a well-ventilated area, preferably on a dedicated battery trolley or stand, away from living spaces due to gas emissions.
• Solar Panels: Install panels on a south-facing (in the Northern Hemisphere) or north-facing (in the Southern Hemisphere) roof or ground mount, free from shading throughout the day. Ensure proper tilt angle for maximum sun exposure.

5.2. Wiring Connections (Overview)

This section provides a general overview. Refer to the detailed wiring diagrams provided with the product packaging for precise connections.

1. Battery Connection: Connect the two LPTT 12150H batteries in series or parallel as specified by the inverter's voltage requirements (typically 24V for this model). Ensure correct polarity (+ to + and - to - for parallel, or + to - for series). Connect the battery bank to the inverter's battery terminals.
2. Solar Panel Connection: Connect the two 330W solar panels in series or parallel to achieve the optimal voltage and current for the inverter's solar charge controller. Connect the combined solar array to the inverter's solar input terminals.
3. AC Input Connection: Connect the inverter's AC input to your main utility power supply (grid).
4. AC Output Connection: Connect the inverter's AC output to your home's load distribution board or specific appliances.
5. Grounding: Ensure the inverter chassis, battery rack, and solar panel frames are properly grounded to an earth electrode.

Warning: Double-check all connections before powering on the system. Incorrect wiring can cause severe damage to the equipment and pose a fire hazard.

6. Operating Instructions

6.1. Initial Power-Up

1. Ensure all connections are secure and correct.
2. Turn on the main AC input breaker to the inverter.
3. Turn on the DC breaker from the solar panels (if applicable).
4. Turn on the battery breaker/switch (if applicable).
5. Switch on the inverter's main power button. Observe the display for status indicators.

6.2. Normal Operation

• Grid Mode: When utility power is available, the inverter will charge the batteries and pass through grid power to your loads.
• Solar Charging: During daylight hours, the solar panels will charge the batteries. The inverter prioritizes solar charging.
• Battery Mode (Backup): In case of a power outage, the inverter automatically switches to battery power, supplying AC power to your connected loads.
• Overload: If the connected load exceeds the inverter's capacity, an overload alarm may sound, and the inverter may shut down. Reduce the load and restart the inverter.

6.3. Shutting Down the System

1. Turn off the inverter's main power button.
2. Turn off the AC input breaker.
3. Turn off the DC breaker from the solar panels.
4. Turn off the battery breaker/switch.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your Luminous system.

• Battery Maintenance (Monthly):
  • Check electrolyte levels in tubular batteries and top up with distilled water if necessary.
  • Clean battery terminals to prevent corrosion. Apply petroleum jelly if needed.
  • Ensure battery area is well-ventilated.
• Solar Panel Cleaning (Quarterly/As Needed):
  • Clean solar panels with water and a soft brush or cloth to remove dust, dirt, and debris. Avoid abrasive cleaners.
  • Ensure panels are not shaded by trees or other obstructions.
• Inverter Inspection (Annually):
  • Check for loose connections or damaged wiring.
  • Ensure inverter ventilation openings are clear of dust and obstructions.
  • Listen for unusual noises.
• Professional Check-up: Consider an annual inspection by a qualified technician.
