3. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your Luminous Solarverter. It is recommended that installation be performed by a qualified technician.
3.1. Site Selection
- Choose a cool, dry, and well-ventilated area, away from direct sunlight, moisture, and flammable materials.
- Ensure adequate clearance around the unit for proper airflow and heat dissipation.
- The mounting surface must be sturdy enough to support the inverter's weight (approximately 18.5 kg).
3.2. Wiring Connections
Before making any connections, ensure all power sources (grid, solar, battery) are disconnected and secured.
- Battery Connection: Connect the 48V battery bank to the designated battery terminals on the inverter. Ensure correct polarity (+ to + and - to -).
- Solar Panel Connection: Connect the solar panel array (up to 3000 Wp) to the solar input terminals. Verify that the open-circuit voltage (Voc) and short-circuit current (Isc) of the array are within the inverter's specifications.
- Grid Input Connection: Connect the AC grid supply to the grid input terminals.
- AC Output Connection: Connect your household loads to the AC output terminals.
- Grounding: Ensure the inverter is properly grounded to prevent electrical hazards.

4. Operation
4.1. Powering On/Off
- To Power On: After all connections are secure, switch on the battery breaker, then the solar array breaker (if applicable), and finally the AC grid input breaker. Press the power button on the inverter's front panel. The LCD will illuminate, and the system will initiate.
- To Power Off: Reverse the power-on sequence. First, switch off the AC grid input breaker, then the solar array breaker, and finally the battery breaker. Press and hold the power button on the inverter until it shuts down.
4.2. LCD Display and Navigation
The LCD display provides real-time information about the system's status, battery levels, and operational parameters. Use the navigation buttons (usually 'Up', 'Down', 'Enter', 'Escape') to browse through menus and adjust settings.
4.3. Operating Modes
The Luminous Solarverter 3KVA offers three user-settable modes to optimize energy usage based on your preferences:
- Solar Mode: Prioritizes solar power for charging batteries and powering loads. Grid power is used only when solar power is insufficient or batteries are low. This mode maximizes solar energy utilization and reduces electricity bills.
- Solar+Grid Mode: Utilizes solar power as the primary source. If solar power is insufficient, the system automatically switches to grid power to supplement or power loads. This mode ensures continuous power supply while still prioritizing solar.
- Grid+Solar Mode: Prioritizes grid power for charging batteries and powering loads. Solar power is used as a secondary source, typically when grid power is unavailable or for specific peak-shaving applications.
Refer to the inverter's LCD menu for instructions on how to select and configure these operating modes.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Luminous Solarverter system. Always disconnect all power sources before performing any maintenance.
- Monthly:
- Inspect the inverter for any visible damage, loose connections, or unusual noises.
- Clean the exterior of the inverter with a dry, soft cloth. Ensure ventilation openings are free from dust and debris.
- Check battery terminals for corrosion and clean if necessary.
- Quarterly:
- Verify that all wiring connections are secure and free from signs of overheating.
- Monitor the performance of your solar panels (e.g., check for shading, dirt, or damage).
- If using flooded lead-acid batteries, check electrolyte levels and top up with distilled water if needed.
- Annually:
- Have a qualified technician perform a comprehensive inspection of the entire solar power system, including the inverter, batteries, and solar panels.
- Test the system's protection features (e.g., MCB, short-circuit protection).
