Installing a rooftop solar system starts with choosing the right inverter. For most Indian homes, a single-phase solar inverter is the most suitable option due to standard residential power connections. This Single-Phase Solar Inverter Price Guide explains current prices in India, factors affecting cost, inverter types, and how to select the best option for long-term savings.
Single Phase Solar Inverter Working
A single-phase solar inverter works by converting solar DC electricity into usable AC power while maintaining voltage and frequency stability. It continuously tracks the maximum power output using MPPT technology to improve energy efficiency. In residential setups, Single Phase On-Grid Inverters operate in synchronization with the utility grid, ensuring smooth power flow and safe system operation.
Solar Inverter Price Factors in India
Understanding pricing factors helps you choose the best inverter for your home without overspending.
Inverter Capacity (kW Rating)
The inverter price increases with capacity. Common residential sizes include 1kW, 2kW, 3kW, and 5kW.
Type of Solar Inverter
- On-grid inverter
- Off-grid inverter
- Hybrid inverter
Among these, Single Phase On-Grid Inverters are the most cost-effective because they do not require batteries.
Technology and Features
Advanced features such as high MPPT efficiency, Wi-Fi monitoring, surge protection, anti-islanding, and wide voltage range increase inverter reliability and price.
Build Quality and Warranty
Better components, strong heat management, and longer warranties increase durability and reduce long-term maintenance costs.
Single Phase Solar Inverter Price in India
| Inverter Capacity | Type | Approx Price Range (₹) | Suitable For |
|---|---|---|---|
| 1 kW | On-Grid | ₹15,000 – ₹25,000 | Small homes |
| 2 kW | On-Grid | ₹25,000 – ₹40,000 | Apartments |
| 3 kW | On-Grid | ₹40,000 – ₹55,000 | Medium households |
| 5 kW | Hybrid | ₹65,000 – ₹1,10,000 | Homes with backup |
| 5 kW | Off-Grid | ₹75,000 – ₹1,20,000 | Power-cut areas |
These prices represent average market ranges and may vary depending on features and location.
Single Phase On-Grid Inverters Price Comparison
On-grid systems are ideal for homes with a reliable grid connection. These systems send excess solar power to the grid, reducing electricity bills significantly. Single Phase On-Grid Inverters are the most popular choice for residential rooftops because they offer high efficiency, low maintenance, and quick return on investment. Their pricing is lower compared to hybrid and off-grid models, making them ideal for budget-friendly solar installations.
Single Phase Off-Grid Solar Inverter Cost
Off-grid inverters are designed for areas with frequent power outages. These systems require batteries to store energy, increasing the total system cost. While inverter pricing is higher, Single Phase On-Grid Inverters are usually preferred where grid availability is stable, as off-grid systems involve additional battery replacement and maintenance expenses.

Single Phase Hybrid Solar Inverter Price
Hybrid inverters combine the benefits of on-grid and off-grid systems. They support battery backup while remaining connected to the grid. Although hybrid systems are more expensive, they provide flexibility during power cuts. Compared to hybrid models, Single Phase On-Grid Inverters remain the most economical choice for homeowners focused mainly on reducing electricity bills.
How to Choose the Right Solar Inverter for Home?
Selecting the correct inverter ensures better performance and long-term savings.
- Calculate Your Electricity Usage: Review monthly units consumed to estimate system size.
- Match Inverter Capacity with Solar Panels: Ensure inverter capacity aligns with panel output.
- Decide on Backup Requirement: If backup is not required, Single Phase On-Grid Inverters are the best choice.
- Check Essential Features: Look for high efficiency, smart monitoring, safety protections, and warranty coverage.
Benefits of High-Quality Single Phase Solar Inverters
Choosing a reliable inverter ensures consistent performance and safety. High-quality inverters deliver better efficiency, stable output, and longer lifespan. In residential systems, Single Phase On-Grid Inverters offer excellent performance with minimal maintenance and lower operational costs.
Solar Inverter Installation and Maintenance Cost
Installation charges depend on system size, wiring, safety devices, and location. Solar inverters require minimal maintenance, but periodic inspection improves longevity. On-grid systems have lower maintenance costs compared to battery-based systems, which is why Single Phase On-Grid Inverters are preferred for urban homes.
Government Subsidy Impact on Solar Inverter Price
Government subsidies apply to the overall rooftop solar system and can significantly reduce project cost. By lowering the total investment, subsidies make efficient systems using Single Phase On-Grid Inverters more affordable for residential consumers.
