7 Picks That Actually Work
We tested and ranked 7 inverters on real-world Indian conditions — grid instability, heat, and DISCOM compliance. Here’s what to buy and why.
Which is the Best Solar Inverter in India Right Now?
For Indian homes in 2026, the Solis 5G (3–10kW) is the best on-grid solar inverter — 98.4% efficiency, DISCOM-approved, and priced ₹18,000–₹45,000. For homes with frequent power cuts, the Growatt SPF hybrid series is the clear winner. Both work with PM Surya Ghar subsidy. Get a free quote to confirm your sizing →
Choosing the best solar inverter in India means more than picking a brand name. Your inverter is the only component in your solar system that decides how much electricity you actually use. Panels generate DC power. The best solar inverter converts it to usable AC with minimal loss. A mediocre inverter on premium panels is like a blocked pipe on a full tank — you lose 10–15% of what you paid for.
Below is a no-nonsense ranking of the best solar inverters available in India in 2026. We evaluated each on efficiency, DISCOM acceptance rate, warranty claim turnaround, and actual installed costs — not factory spec sheets. Whether you need the best solar inverter for home use or a commercial plant, this guide covers every scenario.

Best Solar Inverter Brands in India — In-Depth Analysis
Each of the best solar inverter options in India is reviewed on: real-world efficiency, DISCOM approval status, service network density, and actual warranty claim experience. We’ve ranked them in order of recommendation for most Indian buyers.
Solis (Ginlong Technologies) is the world’s largest string inverter manufacturer by volume, and consistently ranks as the best solar inverter in India for on-grid residential systems. The Solis 5G series has become the go-to choice for DISCOM-empanelled installers — it passes grid compatibility tests in Telangana, Maharashtra, Gujarat, and Karnataka without modification. The monitoring app (SolisCloud) is genuinely useful, not a checkbox feature.
Growatt dominates the hybrid inverter segment in India for one reason: the SPF series handles grid, solar, and battery simultaneously with seamless switching — sub-20ms, which means your sensitive electronics don’t notice a power cut. For Indian buyers facing 2–8 hour daily outages, this is not a luxury, it is the requirement.
Havells Enviro series offers something Chinese brands cannot: 650+ service centres across India, same-day response in most metros, and a brand name that survives committee approval in housing societies and institutions. Efficiency (97.8%) is competitive. It’s not the cheapest, but service friction is near-zero.
Fronius is the premium segment benchmark. The Symo series is overbuilt for residential — it’s designed for rooftop plants where a failure costs lakhs per day. Austrian engineering, 10kW–27.5kW range, and a 7-year standard warranty. If you’re running a hospital, factory, or large commercial building, the premium is justified.
Luminous is not a grid-tied specialist — it’s a backup power company that added solar input. The NXG series is effectively a high-powered UPS with solar charging. Efficiency (95%) trails the pure solar inverters, but if your primary need is keeping the lights on during cuts (not maximising grid export), Luminous is simple, serviceable anywhere in India, and affordable.
Microtek’s primary value proposition is price and availability. The SW Solar series starts under ₹10,000 for small systems. Efficiency (93.5%) is the lowest on this list, which means you lose 1.5–5% vs premium brands annually. Over 25 years, that’s meaningful. But for a 1–2kW system on a small roof with a tight budget, Microtek gets the job done.
SMA is the oldest inverter brand on this list and holds a near-cult following among Indian solar EPC companies for large-scale plants. The Sunny Boy/Tripower range offers 98.1% efficiency and a 10-year standard warranty. It is expensive and over-specified for residential use — but if you’re building a 50kW+ rooftop plant, SMA is the professional-grade default.

Which is the Best Solar Inverter for Your Home? — Decision Guide
The best solar inverter in India for your home depends on one question: do you have reliable grid power? If yes and your bill is ₹2,000–₹5,000: Solis 5G 3–5kW. If your bill is ₹5,000+ or you face daily cuts: Growatt SPF 5–10kW hybrid is the best solar inverter with battery backup. On a tight budget: Microtek or Luminous. Get a free recommendation →
Small Home / 1–2BHK
You need a 1–2kW on-grid inverter. Grid stays connected, no battery needed.
→ Solis 3K-5G or Microtek SW2000
Standard Home / 3BHK
A 3–5kW on-grid or hybrid is ideal. If cuts happen daily, go hybrid.
→ Solis 5G or Growatt SPF 5000
Villa / Commercial
7–25kW system with a quality inverter. ROI in 4–6 years at this scale.
→ Fronius Symo or SMA Tripower
On-Grid vs Hybrid: The Only Question That Matters
If you face zero power cuts or less than 30 minutes daily: on-grid is the correct choice. Hybrid adds ₹40,000–₹80,000 to your system cost for a problem you don’t have.
If you face 2+ hours of cuts daily: hybrid pays for itself in productivity and convenience within 2–3 years. The cost difference versus a generator (fuel + maintenance) is significant.

DISCOM Compatibility: The Fact Most Buyers Miss
Not all inverters are pre-approved by all state DISCOMs for net metering. An unapproved inverter means your net metering application gets rejected — you generate power but cannot export it. Always confirm DISCOM approval in your state before purchase. Solis 5G and Growatt are approved across the widest range of Indian DISCOMs as of 2026.

Best Solar Inverter Installation in India — What Actually Happens
Most buyers research the best solar inverter in India for weeks, then lose 20% of their system performance to poor installation. The inverter brand matters — but so does how it gets mounted, wired, and commissioned.
Step 1: Load Assessment & Sizing
A qualified installer evaluates your monthly unit consumption, peak load (ACs, motors, pumps), and roof orientation. Undersizing your inverter costs you output. Oversizing wastes capital. A 5kW system needs a 5–6kW inverter with 10–20% headroom.
Step 2: DISCOM Application
For grid-connected (net metering) systems, your installer files an application with your state DISCOM before installation. This requires inverter model approval. Timelines vary: Maharashtra MSEDCL approvals take 2–6 weeks; Telangana TSSPDCL is faster at 1–3 weeks.

Step 3: Physical Installation
Inverter placement matters. It must be in shade (not direct sunlight), well-ventilated, and accessible for monitoring. Wall-mounted in a utility room or shaded area is standard. Poor placement causes thermal throttling — the inverter reduces output to prevent overheating.
Step 4: Commissioning & Net Meter Installation
Post-installation, the DISCOM sends an official to install a bi-directional net meter. Until this happens, your system cannot export. Budget 2–8 weeks from application to net meter installation depending on state.
