29 September 2026

Frequent power cuts and rising tariffs make choosing the best inverter company in India an important decision. This guide covers the top 3 inverter companies in India, other popular names, and how to choose between a regular and a solar model. It is written by Lento Industries Private Limited, a solar inverter manufacturer in India.

Quick Answer: Who Are the Top 3 Inverter Companies in India?

Luminous, Microtek and Livguard are three of the most widely recognised inverter brands in India for home and small-business backup. There is no official ranking, so the right company depends on your load, budget, battery type and local service. This list reflects brand recognition and market presence, not an independent lab test.

1. Luminous

Luminous is one of the best-known names in home inverters and batteries in India. It offers a broad range of home inverters, solar inverters and batteries, and it is often the first brand buyers consider for inverter battery backup. Its wide dealer and service network is a key strength.

2. Microtek

Microtek is a long-established Indian brand known for home UPS and inverter products. It is popular for reliable domestic backup and offers a range from basic to feature-rich models. Buyers often shortlist it for its price range and availability.

3. Livguard

Livguard is a fast-growing Indian brand offering inverters, batteries and solar products. It is often compared with Luminous and Microtek in the residential segment, and it is recognised for its combined inverter and battery offerings.

Other Popular Inverter Brands in India

Su-Kam: Su-Kam is widely associated with the early growth of home inverters in India. It offers inverters, solar products and batteries, and many buyers know it for its long presence in the backup power market.

Havells: Havells is a major electrical brand with products from fans and switches to inverters. Buyers who prefer a single trusted brand for home electricals often consider it.

Exide: Exide is best known for batteries. Many households pair Exide batteries with inverters from other brands, so it is often part of the overall inverter battery backup decision.

Growatt: Growatt is an international brand known for string and hybrid solar inverters. It is often chosen for rooftop solar projects with grid-connected setups.

Sungrow: Sungrow is a global solar inverter manufacturer with a strong presence in commercial and utility-scale projects. It is usually compared when buyers want a larger on-grid solar inverter.

Delta: Delta offers solar inverters and power electronics, and it is known for efficiency-focused grid-tie products used in commercial rooftops.

GoodWe: GoodWe manufactures hybrid and grid-tie inverters for residential and commercial use and is a common name in modern rooftop solar installations.

Regular Inverter vs Solar Inverter

A regular inverter charges its battery from the grid and supplies power during cuts. A solar inverter uses panel energy, which lowers electricity bills over time. A hybrid solar inverter combines both, managing panels, batteries and the grid in one unit.

PWM vs MPPT: Which Solar Charge Controller Is Better?

The solar charge controller decides how efficiently panel energy reaches the battery. A PWM solar inverter is cost-effective for small systems. An MPPT model is more efficient for larger arrays and changing sunlight.

Off-Grid vs On-Grid vs Grid-Tie

An off-grid solar inverter runs independently and stores energy in batteries. An on-grid solar inverter exports surplus power and supports net metering where state rules allow, but it stops during outages. A grid-tie solar inverter with hybrid features offers both export and backup.

How to Choose the Right Inverter Company

Calculate your load in watts.
Check service reach in your city.
Compare warranty terms on inverter and battery.
Choose the battery: lithium for long life, tubular lead-acid for lower upfront cost.
Ask for a written quote covering installation.
