I’ve been tracking rooftop solar pricing across Indian installers for solar inverter price a while now, and one question comes up more than any other how much does the inverter itself cost? The short answer is that solar inverter prices move a lot depending on what you’re buying.
Solar Inverter Price
A basic 1kW on-grid inverter can start around ₹8,000, while a solar inverter price large 10kW hybrid inverter can cross ₹1,80,000. For a typical home in India, a 3kW system sits in the ₹18,000–₹35,000 price range, and this single part usually makes up 20–25% of your total solar system cost.
The inverter type, its capacity, the brand behind it, and how many MPPT channels it carries all decide the final number.
String inverters remain the most common type installed on residential rooftops, since they simply convert DC power from your panels into usable AC for the home.
It helps to remember that a grid-tied, on-grid unit shuts down automatically during power cuts as a grid safety measure, which is very different from how a battery-backed inverter behaves.
Solar Inverter Price by Type and Capacity
Once you start comparing quotes, you’ll notice pricing splits neatly by capacity and type, and all figures here are quoted on a GST-inclusive or ex-GST basis depending on the seller.
On the on-grid side, a 1 kW unit from names like Growatt, Solis, or Goodwe runs ₹7,000–₹12,000, a 2 kW option such as the Growatt MIN 2000TL or Solis 2K costs ₹10,000–₹16,000, and a 3 kW pick like the Growatt MIN 3000TL or Delta M3 lands at ₹13,000–₹20,000.
Moving up, a 4 kW unit such as the Sofar 4KTLM-G3 or Solis 4K costs ₹15,000–₹22,000, a 5 kW model like the Growatt MIN 5000TL or Delta solar inverter price M5 costs ₹17,000–₹26,000, and a 6–8 kW system built around the Growatt MID 6–8KTL or Solis 6–8K costs ₹22,000–₹38,000, with 10 kW options like the Growatt MID 10KTL or Goodwe 10K reaching ₹30,000–₹50,000.
Hybrid pricing runs noticeably higher because these units manage battery storage and grid connection at once, letting you keep backup power running through power cuts.
A 3 kW Hybrid built on the Growatt SPH3000, Sofar HYD3600, or Solis RHI-3K costs ₹18,000–₹28,000 and pairs with Lithium LFP or Lead Acid batteries, a 3.6–4 kW Hybrid such as the Goodwe GW3600-ES or Solis 4K Hybrid costs ₹22,000–₹32,000 with Lithium LFP, and a 5 kW Hybrid like the Growatt SPH5000, Sofar HYD5000, or Solis 5K costs ₹28,000–₹42,000.
At the top end, a 6–8 kW hybrid such as the Growatt SPH6000–8000 or Goodwe GW6000 costs ₹38,000–₹62,000 and can pair with an HV Battery, while a 10 kW Hybrid like the Growatt SPH10000 or Goodwe GW10K-ET costs ₹60,000–₹90,000 and typically needs a High Voltage Lithium pack.
Off-Grid systems, sometimes sold as a solar home UPS or PCU (Power Conditioning Units), work independently of the utility grid and are common in rural areas or for backup-first customers who pair them with lead acid batteries.
Pricing here moves from around ₹8,000–₹12,000 on the smallest units to well over ₹70,000–₹1,20,000 on larger systems. Lastly, Micro inverters solar inverter price are priced per panel rather than as one unit — figure roughly ₹8,000–₹12,000 for a per-panel unit, so a system using 6 panels would total near ₹48,000–₹72,000.
Why Do Inverter Prices Vary So Much?
From what I’ve seen on real installs, the price difference between two inverters of the same capacity almost always comes down to a handful of things.
First is simply the internal build a unit with a battery charger, transfer switch, and full battery management system costs 2–3x more than a plain on-grid box, since it needs far more management circuits inside.
Second is brand: European brands like Fronius from Austria or SMA from Germany sit 30–60% above Chinese names like Growatt and Goodwe, and Enphase known for panel-level optimisation — carries its own premium too, while Indian names like Havells and Microtek sit somewhere in between.
Third, the number of MPPT channels matters more than people expect. A Single-MPPT unit is cheaper, but a Dual-MPPT inverter earns its extra cost solar inverter price back through 5–15% better output on complex roofs with panels facing two directions.
Fourth is monitoring built-in Wi-Fi with app-based monitoring adds ₹1,000–₹3,000, and it’s genuinely worth it for tracking daily performance.
Finally, warranty length plays a role: a standard 5-year warranty is common, and paying ₹3,000–₹8,000 extra for ext.10 coverage is a smart move given how much shorter an inverter’s life is compared to the panels it serves.
Solar Inverter Price by Brand
Sticking to a 3 kW on-grid comparison makes brand differences easy to see. Growatt runs ₹18,000–₹24,000 with 5 years (ext.10) cover and a strong app, Goodwe runs ₹20,000–₹26,000 with a wide voltage range, and Havells runs ₹22,000–₹30,000 solar inverter price backed by a solid local service network. Polycab, a trusted Indian brand, sits close by at ₹22,000–₹28,000.
On the premium side, Fronius from Austria costs ₹32,000–₹45,000 and is known for premium efficiency, while SMA from Germany costs ₹30,000–₹42,000 and is often treated as an industry benchmark.
Enphase, built around micro units, totals ₹48,000–₹72,000 for a full 3kW setup but comes with an unmatched 25 years of cover.
For most homes, Growatt and Goodwe strike the best balance of price, output, and after-sales support.
On-Grid vs Off-Grid vs Hybrid
The gap between these three widens as capacity grows. On-grid stays 40–60% cheaper than hybrid and also qualifies for the PM Surya Ghar subsidy, making it the default for net metering setups.
Off-grid costs 30–50% more than on-grid because it packs in a battery charger and control circuits, and once you add battery cost anywhere from ₹40,000–₹1,50,000 the full off-grid setup climbs fast.
Hybrid remains the priciest string inverter option since it bundles grid-tie, an automatic transfer switch, and a charger in one box, but that premium is solar inverter price worth it if backup during outages actually matters to you.
Unless you specifically need batteries, sticking with on-grid and spending the savings on higher-quality panels is usually the smarter call.
How Inverter Cost Fits Into Total System Price?
Your inverter is only one line in the full rooftop solar system cost, so here’s the typical cost breakdown for a 3kW on-grid build. Solar Panels take up 40–50%, roughly ₹65,000–₹95,000, while the Solar Inverter itself is 20–25%, or ₹18,000–₹35,000.
Mounting structure hardware runs 10–15%, near ₹12,000–₹22,000, and Wiring & Electrical work adds 5–8%, close to ₹8,000–₹14,000. Installation Labour takes another 5–10%, around ₹8,000–₹15,000, and Net Metering & Approvals rounds it out at 2–5%, roughly ₹3,000 8,000.
Stepping up from a basic models unit to a premium one solar inverter price only adds ₹10,000–₹20,000 to the whole 3kW build, which is a fair trade for better longevity and efficiency.
Tips to Get the Best Inverter Price
A few habits genuinely save money here. Always compare quotes from two or three installers, since markups vary a surprising amount, and a free quote service with clear itemised breakdowns makes this easy.
Read the warranty terms closely a cheap extended warranty around ₹3,000–₹8,000 is real cheap insurance on a part with a 10–15 years lifespan. Don’t oversize the solar inverter price panel array; matching a 3.3kW panels setup to a 3kW inverter through slight right-size planning improves utilisation without waste.
If your roof has panels on east and west faces or is partially shaded, prioritise MPPT count a Dual-MPPT unit justifies premium pricing here. And don’t skip Wi-Fi-enabled inverters; being able to spot issues early and watch daily output through tracking performance tools is worth the small premium every single time.
FAQS About Solar Inverter Price

Yes, a 3kW system can run a 1–1.5 ton AC easily with a matching on-grid or hybrid inverter. Just keep your inverter capacity aligned with your home load.
How much is a 10 kW solar inverter?
A 10kW inverter costs ₹50,000–₹90,000 on-grid, up to ₹1,00,000–₹1,80,000 for hybrid. Brand and MPPT channels shift the price within this range.
Which solar inverter is best for a home?
Growatt and Goodwe give the best price-to-output balance for a standard 3kW on-grid home setup. Choose hybrid only if backup power during outages matters to you.
How much does a 1 kW solar inverter cost?
A 1kW on-grid inverter costs ₹7,000–₹14,000, with off-grid and hybrid running higher. The added cost comes from extra battery charger and management circuits.
