Best Hybrid Solar Inverter in India: 2026 Checks

Last updated: November 2026

There is no single best hybrid inverter for every Indian home. The right pick follows your wiring and your battery, and the paperwork behind the exact model.

A hybrid inverter connects solar panels, a battery and the grid. It can power your home from the battery when the grid fails. This page compares models using only facts the makers publish on their own sites. The tables are in alphabetical order. They are not a ranking, and they report published specifications only, not field results.

SurgePV publishes this guide. SurgePV sells solar design software, not inverters. It has a commercial relationship with Qbits Energy, an inverter maker. Qbits is not in the tables below.

Hybrid Inverter Comparison: Global Families

Phase means how your home is wired. Single-phase homes have one live wire. Three-phase homes have three. kW is real power. kVA and VA are apparent power, a close but slightly different measure. MPPT (maximum power point tracker) is the input that tunes one group of solar panels. A battery voltage of 40 to 60 V is called low-voltage. A range of 120 V or more is called high-voltage.

Sources: the GoodWe ES Uniq page, the Deye SUN-3/4/5/6/8/10/12K-SG05LP3-EU-SM2 manual (datasheet section, file dated 19 March 2026), and the Solis datasheets for the 3 to 10 kW models and the 12 kW model. The Solis S6-EH3P product page links the same documents. All were read on 28 October 2026.

Notes on the table:

• Deye model list. The Deye datasheet lists 3, 4, 5, 6, 8, 10 and 12 kW. It has no 7 kW or 9 kW model. The model name ends in EU, and the datasheet lists European grid rules such as EN 50549 and VDE-AR-N 4105. Ask which version Deye or its distributor sells in India.
• GoodWe. The GoodWe page says ES Uniq works in on-grid and off-grid systems. It says up to 6 inverters can run in parallel, and the page links a battery list. For 3 to 6 kW models, the page lists 20 A per MPPT input. For the 8 kW model it lists 32 A and 16 A. For 10 and 12 kW it lists 32 A on each input.
• Solis page and datasheet disagree. The Solis product page says maximum input voltage 500 V and an MPPT range of 100 to 450 V (200 to 850 V for 12 kW), and 3 or 4 MPPTs. The datasheets say maximum input 1,000 V, an MPPT range of 200 to 850 V, and 2 to 4 MPPTs. Ask Solis which document applies to the model you buy.
• Solis battery. The datasheet names one battery family, SolisStor-(15-40)kWh-H-ST-66, with 1 to 8 modules. The 3 to 10 kW datasheet footnotes a maximum battery voltage of 700 V.

Hybrid Inverters From Indian Brands

Luminous and Microtek publish hybrid inverter pages with prices. The prices below are what each page showed on 28 October 2026. They can change. kVA is the size Luminous uses. Microtek states both kW and kVA, and the two values are equal on the pages read.

Sources: the Luminous hybrid inverter list, the Luminous TX 5 kVA page, the Luminous NXH 150 A48 page and the Microtek solar hybrid inverter list. Each Microtek model has its own page under that list.

Notes on the table:

• Luminous. The list shows 26 hybrid products, from 3 kVA to 250 kVA. The TX 5 kVA page says it has 48 V battery support, grid export and anti-islanding protection. Anti-islanding stops the inverter from feeding a dead grid.
• Microtek. The product tables show efficiency, ingress protection, weight and size. The Microtek list marks each price “Inclusive of all Taxes”. Ask Microtek for the battery voltage and solar input limits before you plan the system.
• Prices. For typical prices by size, read the 5 kW hybrid inverter price and 8 kW hybrid inverter price guides.

Which Hybrid Inverter Fits Your Home?

Start with the building, not the brand.

Single-phase home with backup for key circuits. Make a list of what must stay on in a power cut. Write down each circuit’s running power, start-up power and daily energy. GoodWe ES Uniq, Luminous and Microtek single-phase models are the families in this guide that fit. Check the exact capacity, battery, solar strings and India papers for each.

Three-phase home. Check each phase on its own. Your total kW can be under the inverter rating while one phase is over its limit. The Solis datasheet says the maximum power per phase is 50% of rated power. So a 10 kW Solis unit gives up to 5 kW on one phase. Deye and Solis are the three-phase families here, and Microtek lists two three-phase models.

Small business site. A business site needs more than a bigger home design. You must review the transformer, switchboard, fault level, export control and shutdown steps. The commercial inverter selection guide covers these.

Avoid putting big loads on backup without a calculation. Water heaters, electric cooking, several air conditioners and pumps drain a battery fast.

Low-Voltage or High-Voltage Battery?

Neither is better for every project. The difference is current. At the same power, a lower battery voltage needs more current.

A quick screening sum: current = power / voltage. For 5,000 W at 48 V, that is 5,000 / 48 = 104.2 A. At 400 V, it is 5,000 / 400 = 12.5 A. This ignores losses, so use it only to compare. The makers’ own tables are close to this scale. GoodWe lists 120 A maximum charge and discharge current for its 5 kW model (GW5000-ES-C10). Deye lists 120 A for its 5 kW model (SUN-5K-SG05LP3-EU-SM2).

Do not mix batteries because they look alike. Use the maker-approved set. A battery management system (BMS) is the electronics that watch each cell and tell the inverter its limits. The inverter and battery must speak the same BMS language. Ask both makers to approve the exact pairing in writing.

The hybrid inverter guide explains how the parts connect.

Size the Backup and the Battery

Inverter size is one limit. The battery, the phase and the battery charge level can set a lower one.

Make a circuit list with these columns: running power, start-up power, phase, hours needed in an outage, and what to switch off first.

Worked example. Say your home uses 3.5 kW on average for 4 hours. That is 3.5 x 4 = 14 kWh of energy delivered. Say the outage starts with the battery at 95%, you stop at 10%, and 93% of the battery’s energy reaches your loads. The battery size you need is:

14 / ((0.95 - 0.10) x 0.93) = 14 / 0.7905 = 17.71 kWh

This is a teaching example, not a product pick. Real batteries lose capacity with heat and age. Use the maker’s usable-energy figure.

Motor start-up. Pumps, fridges and air conditioners pull more power for a moment when they start. List each one. Then check the inverter’s overload rating. Deye lists a peak of 2 times rated power for 10 seconds. Solis lists 1.6 times rated power for 60 seconds. Test the real motors when the system is commissioned.

Essential-load board. This is a separate panel for the circuits that stay on during a cut. Label it clearly. Show the owner what to switch off after a low-battery event.

Match the Solar Strings

Total panel power is not enough. Check each string against the inverter’s voltage and current limits. For each string:

1. Work out the cold-weather open-circuit voltage at your lowest design temperature.
2. Work out the hot-weather operating voltage.
3. Check both against the inverter’s start-up and working range.
4. Check the current per MPPT input.
5. Group strings by roof direction, tilt and shade.

Use the datasheet for the exact model. A nearby model can have different limits. Both Deye and Solis publish how much panel power you can connect. Deye lists 6,000 W for its 3 kW model and 24,000 W for its 12 kW model. Solis recommends a 6 kW array for its 3 kW model and 24 kW for its 12 kW model. That is 2 times the rated output in both cases.

DC-to-AC ratio is panel power divided by inverter AC power. A 10 kWp array on an 8 kW inverter gives 10 / 8 = 1.25. Treat the ratio as a result of your design, not a target. A shade study helps you split roof groups. SurgePV’s solar design software covers layout, shading and electrical workflow support. Use the generation and financial tool to model yield and cash flow.

Check Transfer, Island, Bypass and Generator Modes

Words like “backup” or “generator-ready” do not describe how a system behaves. Write down each mode you need and test it.

• Grid loss. Check what happens to your loads when the grid drops. Test sensitive electronics and motors.
• Island mode. The system runs on its own, apart from the grid. Check how neutral and earthing work in this state.
• Black start. This means starting the system with no grid. Ask for the battery level it needs and the steps after a deep discharge.
• Bypass. Name what it does: pass grid power through, bypass an overload, or allow maintenance. The GoodWe page describes a “3-in-1 port” for a generator, smart loads and an on-grid inverter. Solis lists generator access on the grid side. Ask both for the exact wiring.
• Generator. Get written approval from the inverter maker and the generator maker. Test charging, load steps and the switch back to grid.

Ask for India Grid and Safety Papers

A hybrid inverter is not automatically approved to export power. Ask your DISCOM (power distribution company) for its connection rules. Ask your installer for the exact model’s papers.

The BIS Scheme II page lists solar products under compulsory registration. For inverters it names IS 16221 (Part 2), IS 16169 and IS 16270. It also lists a 2025 order for solar inverters above 200 kW. Ask the installer which registration applies to your model, and ask to see the record. Check the MNRE quality-control page for the current orders.

ALMM is for solar modules, not inverters. Do not accept “ALMM-listed” as a claim for an inverter.

Ask for a single line diagram (SLD), a simple drawing of how the system is wired. It should show the grid input, inverter output, backup output, battery isolation, solar isolation, protection devices, neutral and earthing in every mode, and export control.

Compare Warranty and Service in Writing

Warranty years are only one number. The remedy matters more. These are the terms published on the pages in this guide:

• Deye lists “5 Years/10 Years”, and says the period depends on the final installation site.
• Microtek lists 5 years on its hybrid inverter pages.
• Luminous lists 36 months on the TX 5 kVA page and 60 months for the NXH 5 kVA in its list.

Ask each bidder for the full written remedy. It should say who pays for diagnosis, travel, removal, shipping, a replacement and setting it up again. It should also give response times and the name of one person who owns the fault. Faults can sit in the inverter, battery, meter or wiring, so one named owner prevents delays.

The inverter warranty guide compares remedies.

Compare Complete Quotes

A bare inverter and a fitted backup system are different purchases. Ask each bidder to price every line below, so quotes can be compared like for like.

Add up the quote and every missing item: evaluated price = quoted package + priced omissions + owner work + mandatory charges. Do not hide missing scope behind a percentage. Link payment to delivery, passed tests, complete records and closed defects.

Test Before You Pay the Final Bill

Before power-up, check models, serial numbers, firmware, mounting, clearances, polarity, cables, earthing, labels and communication. Then run these tests:

• Normal grid-connected running
• Solar and battery charging within limits
• Grid loss with a real essential load
• Backup on each phase and circuit
• Agreed motor starts
• Bypass, isolation and emergency steps
• Generator switch-over, if fitted
• Grid return and reconnection
• Low-battery shutdown and restart
• Export control and a lost internet link

Record loads, voltage, current, battery level, times, alarms and results. A demo with no load is not an acceptance test. Give the owner the monitoring login and a copy of the settings.

How This Comparison Was Built

Facts come from each maker’s own pages and datasheets, read on 28 October 2026. No dealer pages, marketplace listings or reviews were used. The tables show what the makers publish. They do not show field performance, India approval or service quality. Makers can change pages and models after this date.

Qbits Energy, which has a commercial relationship with SurgePV, is not in the tables. Brands not listed here were not compared. UTL Solar is not in the tables.

If you do not need backup, compare on-grid options in the best on-grid inverter guide. To see how the system types differ, read on-grid, off-grid and hybrid systems. To plan the solar side of a hybrid project, book a SurgePV demo.

Frequently Asked Questions

Which is the best hybrid solar inverter in India?

No single model is best for every home. Phase and battery voltage narrow the list. Single-phase homes can compare GoodWe ES Uniq, Luminous and Microtek models. Three-phase homes can compare Deye SG05LP3 and Solis S6-EH3P. Then check the exact model’s India papers, battery list, warranty and service terms.

Will a hybrid inverter power my whole house in a power cut?

Not by default. Backup is limited by the inverter’s backup output, the battery, and each phase. The Solis datasheet, for example, limits each phase to 50% of rated power. Most homes put key circuits on an essential-load board and leave heavy loads off it.

Can any lithium battery work with any hybrid inverter?

No. Matching voltage is not enough. The inverter and battery must use the same BMS signals. GoodWe links a battery list on its ES Uniq page. Solis names one battery family, SolisStor-(15-40)kWh-H-ST-66, in its datasheet. Ask both makers to approve the exact pairing in writing.

Is a low-voltage or a high-voltage battery better?

Neither wins every time. A low-voltage battery (40 to 60 V on the Deye and GoodWe models here) needs more current for the same power. A high-voltage battery (120 V or more on the Solis model here) needs less current but needs trained service. Compare the full approved system.

Is a hybrid inverter allowed to export power under net metering in India?

Not automatically. Export depends on your DISCOM’s rules, the metering and the inverter’s papers. Ask your installer for the exact model’s BIS registration record and grid-connection documents. Get your DISCOM’s approval in writing before power-up.

How do hybrid inverter warranties compare?

Compare the remedy, not just the years. Deye lists 5 or 10 years, depending on the installation site. Microtek lists 5 years. Luminous lists 36 months on its TX 5 kVA page and 60 months for its NXH 5 kVA in its list. Ask who pays for diagnosis, travel, removal and a replacement.

What does a hybrid inverter cost in India?

On 28 October 2026, Microtek’s pages showed ₹90,000 for 3 kW up to ₹189,900 for 10 kW. Luminous showed ₹63,899 for a TX 5 kVA and ₹1,05,999 for an NXH 5 kVA, inclusive of all taxes. These are inverter prices from the makers’ pages. Ask each bidder to price the battery and installation too.
