If you’re facing regular power cuts or are tired of paying high electricity bills every month, it’s time to consider switching to solar energy. Luminous, one of the most trusted brands in India, offers a 3kW off-grid solar system that promises up to 25 years of free power. Designed for homes, villas, offices, and independent floors, this system is perfect for people who want to reduce their dependency on grid electricity.
What Makes the Luminous 3kW Solar System So Special?
This off-grid solar setup uses Mono PERC solar panels, which are known for high efficiency and better performance even in cloudy weather. With this system, you can generate 10 to 12 units of electricity daily, enough to power your daily home appliances. It works independently from the main electricity grid, making it perfect for remote areas or places with frequent power cuts.
One of the best parts of this system is that it includes the Luminous NXT+ 3.75kVA solar inverter, which intelligently manages power flow from solar, battery, and grid to ensure continuous electricity. The inverter uses MPPT (Maximum Power Point Tracking) technology for better battery charging and performance.
What Appliances Can You Run With It?
This solar system is ideal for running your essential household items. You can connect a combination of fans, lights, and appliances that add up to 2600 watts of power. However, it is not designed to run heavy appliances like 1.5-ton or 2-ton air conditioners, 2HP motors, or water heaters.
Here is a sample list of what you can power with this system:
| Appliance | Quantity Supported |
| Ceiling Fans | Up to 5 |
| LED Lights | 4 to 8 |
| Cooler | 2-3 |
| AC (1 Ton) | 1 |
| LED TV | 1 |
| Single Door Fridge | 1 |
| Wi-Fi Router | 1 |
| Mixie | 1 |
| Laptop/Mobile Charging | Multiple devices |
It also provides a backup time of 5–6 hours with a 1000W load and up to 7–8 hours with an 800W load, making it suitable for nighttime usage or power outages.

The Luminous 3kW solar system is a complete package that includes everything needed for installation and use. The combo includes:

What’s the Total Cost of This Setup?
The cost of the Luminous 3kW off-grid solar system usually falls in the range of ₹1,75,000 to ₹2,30,000 including all parts and installation.
