Best suited for: Residential buyers comparing home inverter and power backup products.

5. Exide

Exide is widely associated with batteries and also offers inverter-related products. For buyers planning a conventional backup system, battery compatibility is an important factor when selecting an inverter.

Compare the inverter's charging current, supported battery capacity, recommended battery type and warranty conditions. A suitable battery-and-inverter combination can help meet the required backup time without exceeding the system's operating limits.

Best suited for: Buyers comparing inverter-and-battery combinations for home and small-business backup.

6. Livguard

Livguard offers products across the power backup and energy solutions market, including inverters and batteries. Available product features differ by model, so buyers should review the specifications rather than assume every model supports the same battery technology or charging options.

Before purchasing, confirm the rated capacity, battery compatibility, charging time under specified conditions, warranty and service arrangements.

Best suited for: Customers comparing inverter and battery solutions for residential power backup.

7. Su-Kam

Su-Kam has operated in the power backup and solar energy sector. When considering its products, check the current availability of the specific model, technical documentation, warranty terms and after-sales support.

For any inverter brand, a pure sine wave model may be appropriate for many household appliances, but the required capacity and supported load must still be checked.

Best suited for: Residential, commercial and larger solar projects where solar generation is a primary requirement.

10. Growatt

Growatt offers solar inverters and energy storage solutions for different system sizes. Its suitability depends on the application, available model, system configuration and local technical support.

Buyers should establish whether they need a grid-connected solar inverter, an off-grid system, a hybrid inverter or a solution that supports battery storage. These configurations serve different purposes and should not be treated as interchangeable.

Best suited for: Customers and solar installers comparing residential and commercial solar inverter and energy storage options.

How to Choose the Best Inverter Company in India

The best inverter company for your needs depends on the application and the products available for it. Compare the following factors before making a purchase.

1. Identify your power requirements

List the appliances that need backup, including lights, fans, routers, televisions and other equipment. Calculate their combined running load and account for appliances with high starting currents.

The inverter must support the actual load, not just the number of appliances connected to it.

2. Select the right inverter capacity

Inverter capacity is commonly expressed in VA or kVA, while appliance consumption is generally expressed in watts.

For example, a home with a few lights, fans and a router may need a different capacity from a home that also runs a refrigerator or other high-starting-current appliances.

Read our guide to choosing the right inverter for home use before deciding on a model.

3. Compare battery options

The main options include tubular, SMF and lithium batteries, depending on the inverter's compatibility.

• Tubular batteries: Commonly used in conventional home backup systems. Check capacity, charging requirements and maintenance instructions.
• SMF batteries: Sealed batteries used in compatible backup applications. Check the manufacturer's recommended operating conditions.
• Lithium batteries: Can offer a compact integrated or separate battery solution. Check battery chemistry, BMS protection, usable capacity and warranty.

For a detailed comparison, read which inverter and battery combination is suitable for home use.

4. Decide between conventional and inbuilt lithium inverters

A conventional inverter generally uses a separate battery, while an inbuilt lithium inverter integrates the battery into the unit.

The integrated option can reduce external battery connections and save installation space. However, buyers should compare the built-in battery capacity, rated load, backup expectations, replacement arrangements and warranty terms before choosing.

See Lento's inbuilt lithium battery inverter range.

5. Check solar compatibility

If you plan to use solar panels, confirm that the inverter supports the intended system configuration.

Check:

• Maximum PV voltage and current
• Supported solar array power
• PWM or MPPT controller specifications
• Battery compatibility
• Grid and off-grid operating modes
• Installation and protection requirements

An MPPT controller can improve solar energy harvesting under suitable operating conditions, but actual performance depends on the panel configuration, weather and system design.

6. Compare warranty and after-sales service

Before buying, verify the warranty for the inverter and battery separately, where applicable. Also check service coverage, authorised service arrangements, spare-parts availability and the procedure for making a warranty claim.

Do not assume that every product from the same brand has identical warranty coverage.

7. Compare the total cost

The purchase price is only one part of the total cost. Depending on the system, additional expenses may include the battery, solar panels, mounting equipment, wiring, protection devices and installation.

Use our inverter price guide for India and latest inverter price list to continue comparing available options. Confirm current prices and product availability before ordering.

Which Inverter Company Is Best for Home Use?

For home use, compare companies that offer an inverter capacity suitable for your appliances, compatible battery options, appropriate output waveform and accessible after-sales service.

A pure sine wave inverter is a common choice for household backup, but the correct capacity and battery combination matter just as much. Buyers who need a compact integrated system can compare inbuilt lithium models, while those planning a solar installation should examine the solar input and operating specifications.

Read our detailed guide to which inverter is best for home use in India, including battery price considerations.

Which Company Is Best for Solar Inverters?

The answer depends on the type and size of the solar project.

For a home backup system, buyers may prefer a suitable hybrid or off-grid inverter. Commercial and utility-scale projects require a different assessment of power rating, grid configuration, installation conditions and technical support.

Compare the intended use, PV input specifications, efficiency data, battery support and warranty before selecting a solar inverter manufacturer.

Can You Buy a Single Inverter Online?

Yes, single-unit purchases may be available through a brand's website or authorised online marketplace listings. Availability varies by model and seller.

You can check the Lento Amazon Store to compare listed Lento products, pricing, customer reviews and delivery details.

For bulk purchasing, dealership enquiries or B2B requirements, contact the manufacturer directly to confirm minimum order quantities, pricing, specifications and dispatch terms.
