Solar Inverter Price in India 2026 — On-Grid, Hybrid and Off-Grid Compared
The solar inverter price in India in 2026 depends mainly on the type and capacity. A residential on-grid inverter typically costs about ₹8,000 to ₹13,000 per kW, which means ₹40,000 to ₹65,000 for a 5kW unit. Hybrid and off-grid inverters cost more because they manage batteries as well.
The inverter is the most important quality decision in a solar system. Panels last 25 years or more, but an inverter works hard every day and is the component that fails first. This guide explains the types, indicative prices, key features, warranty and the mistakes to avoid when you buy.
What Does a Solar Inverter Do?
Solar panels produce direct current (DC). Your home runs on alternating current (AC). The inverter converts one into the other, synchronises with the grid, tracks the best power point of the panels, and shuts down safely if the grid fails. It is also the brain that reports how much power you generate.
Solar Inverter Price in India by Type
| Type | What it does | Cost level | Best for |
|---|---|---|---|
| On-grid (grid-tie) string inverter | Sends power to your home and the grid, no battery | Lowest | Most Delhi homes and businesses |
| Hybrid inverter | Works with the grid and a battery for backup | Higher | Homes with frequent power cuts or backup needs |
| Off-grid inverter (PCU) | Works only with batteries, no grid connection | Higher, plus battery cost | Remote sites without reliable grid |
| Microinverter | One small inverter per panel | Highest per kW | Roofs with heavy partial shading or complex layouts |
Indicative On-Grid Solar Inverter Price by Capacity
These indicative ranges are scaled from the inverter cost we see in a standard 5kW home installation, which is about ₹40,000 to ₹65,000 for the inverter alone. They are not a price list, and actual prices vary by brand, model and market conditions.
| Capacity | Indicative on-grid inverter price |
|---|---|
| 3 kW | ₹25,000 – ₹40,000 |
| 5 kW | ₹40,000 – ₹65,000 |
| 10 kW (three-phase) | ₹75,000 – ₹1,20,000 |
Hybrid and off-grid inverters are priced higher, and the battery adds a large separate cost. A complete 5kW hybrid system with a 5 kWh battery costs about ₹4.20 lakh to ₹5.20 lakh in total, compared with ₹3.10 lakh to ₹3.60 lakh for on-grid. See our solar battery price guide and grid-tied vs hybrid vs off-grid to decide.
What Affects the Solar Inverter Price?
- Capacity and phase: single-phase inverters are cheaper than three-phase. A home system above about 5kW usually needs a three-phase connection and inverter.
- Brand and warranty: established brands cost more but provide better service and longer warranties.
- Number of MPPT inputs: more inputs help with roofs that face different directions.
- Efficiency: good inverters reach around 97% to 98.5% efficiency. Even a 1% gain matters over 10 years.
- Monitoring: Wi-Fi or app monitoring may be built in or may need an extra dongle.
- Protection rating: a higher ingress rating, such as IP65, is better for outdoor mounting in dust and rain.
- Battery support: hybrid models have extra hardware and software.
Features to Check Before You Buy
- Grid-tie approvals: the inverter must meet the technical rules for grid connection, including anti-islanding protection, as DISCOM inspectors verify inverter specifications.
- Warranty length and service: ask for the warranty period, the replacement process and the local service centre.
- Efficiency and MPPT range: check that the inverter’s voltage range suits your panels.
- Over-sizing ratio: panels are often sized 10% to 30% above the inverter’s rating. The installer should explain the ratio.
- Heat performance: Delhi summers are harsh. Ask about derating at high temperature.
- Monitoring: insist on remote monitoring so you can see daily generation, which helps to spot faults.
- Surge protection: a good system adds DC and AC surge protection around the inverter.
Inverter Brands Available in India
The Indian market includes well-known domestic brands and global manufacturers. At Solar Squad, the equipment options we work with include brands such as Solis, Deye, Havells and Luminous, among others. The right choice depends on your system type, budget and the service support available in your area. Never choose on brand alone. Check the exact model, the warranty and the local service network.
How Long Does a Solar Inverter Last?
Most string inverters last around 8 to 12 years, which is shorter than the 25-year life of the panels. Plan for at least one replacement during the life of your system. Heat, dust, poor ventilation and surges shorten inverter life, so a well-ventilated, shaded wall mounting location helps. Read more about component lifetimes in our guide to solar panel lifespan in India.
Why a Very Low Solar Inverter Price Is Risky
- It may have a lower efficiency, and you lose power every day.
- It may shut down in hot weather and lose generation in peak hours.
- It may lack proper protection and fail during surges or storms.
- Service and spare parts may be hard to get.
- A failed inverter stops all generation, so every day of downtime costs you money.
A saving of ₹10,000 on the inverter can be lost in a single year of reduced generation and repairs. That is why a component-wise quote matters. Our 5kW solar system price guide shows how the inverter fits into the full cost breakdown.
Which Solar Inverter Price and Type Suit Your Home?
- Short power cuts and a net-metered home in Delhi: an on-grid inverter is usually the most economical choice.
- You need backup for lights, fans, router and a fridge: consider a hybrid inverter with a small battery.
- Heavy partial shade: consider multiple MPPT inputs, or microinverters.
- Future expansion: choose a model that allows you to add panels or a battery later.
Only on-grid and hybrid systems installed through a registered vendor with ALMM-listed panels qualify for the central subsidy. Off-grid systems do not. See solar subsidy in Delhi for details.
Conclusion: What Is a Fair Solar Inverter Price?
The solar inverter price in India in 2026 ranges from about ₹25,000 for a 3kW on-grid unit to well over a lakh for large or hybrid models. Treat the inverter as a quality decision rather than a place to save. Check the warranty, the efficiency, the service network and the grid approvals, and plan for one replacement over the life of the system.

FAQs
What is the price of a 5kW solar inverter in India?
A good-quality on-grid 5kW inverter typically costs about ₹40,000 to ₹65,000 in 2026. Hybrid inverters cost more.
What is the difference between an on-grid and a hybrid inverter?
An on-grid inverter works with the grid and has no battery. A hybrid inverter works with the grid and a battery, so it can supply backup power during an outage.
How long does a solar inverter last?
Typically 8 to 12 years for a string inverter, so you should plan for at least one replacement over a 25-year system life.
Is the inverter covered under the PM Surya Ghar subsidy?
The subsidy is paid on the complete system capacity, not on individual parts. The system must meet scheme rules and be installed by a registered vendor.
Can I use a normal home UPS inverter with solar panels?
No. A normal UPS inverter is not designed for solar input. You need a solar-compatible on-grid, hybrid or off-grid inverter.
