5 Best Inverters in India : 2020 Reviews & Buying Guide

In India, the power cuts are generally frequent and unannounced. Thus, an inverter is a must-buy so that you have a continuous source of power.

When compared to generators, buying an inverter is way more economical. With so many models of inverters available in the market, it becomes a bit difficult to choose the best one.

Here are some factors that you should consider before buying an inverter.


There are 3 types of inverters: Sine wave, Modified sine wave, and square wave.

Pure sine wave inverters: These types of inverters are an ideal choice for the high-powered electrical appliances including laptops, microwaves, and TVs. When compared to the other types of inverters, these are costlier.

Modified sine wave inverters: The modified inverters work the best with electrical appliances with resistive loads that don’t really require any start-up surge. The only issue with these inverters is some users say that they reduce the efficiency of the electrical appliances.

Square wave inverters: These are the cheapest types of inverters and are best suited for appliances with a lower sensitivity rate such as fans and lights.

2. Inverter capacity

You must check the capacity and battery size of the inverter. You can decide this by checking how many devices do you want to use and for how many hours.

The capacity of an inverter is calculated in Volt-Amp (VA). Here is the formula to calculate VA:

VA = Power required / Efficiency (Power factor)

In India, the power factor or efficiency varies between 0.6-0.8.

To explain this in a better way, let’s take an example.

If you want to use 2 CFL bulbs, 1 TV, 2 fans, and 1 tube light on the inverter, the total power required would be:

2*25 + 1*120 + 2*80 + 1*50 = 380 watts

VA = 380/0.8 = 475 VA

Thus, if this is your requirement, you can go with an inverter that offers a capacity of 500 VA.

3. Battery size:

To calculate the size of the battery required, you can check the following formula:

Inverter’s VA rating X usage time (in hours) / input voltage = Battery size

A regular inverter offers an input of 12 volts. Now, let’s say you wish to use a 500 VA inverter for 6 hours backup, the required battery size can be calculated as follows.

500 VA X 6 hours/12V = 250Ah

The other factors that must be considered before buying an inverter for your house are warranty, types of batteries, and cost. We have explained them in detail in the Buying Guide below.We tested more than 10 best-quality inverters available in the market. After extensive research and going through all the reviews, we have shortlisted 5 best inverters for you. Let’s have a look!

Buying Guide – All You Need To Know About Inverters

What is an inverter?

An inverter is an electrical device that helps in converting DC (direct current) into AC (alternating current) at any frequency or voltage. In general scenarios, all the appliances run on AC but when the main power goes off, the inverter works on converting DC into AC from the battery backup so that the appliances work without any interruptions.

The switch-over time between these conversions is so less that the devices don’t turn off even if there is a complete power cut. You can use inverters as a power backup for all the appliances at your home. The size of the inverter’s battery system depends on your requirements.

If you wish to use it only for smaller appliances such as light and fans, you can go for inverters with smaller battery capacity. However, if you wish to use it as a backup for bigger appliances like washing machine or fridge, you should buy bigger inverters. But experts suggest avoiding adding such bigger appliances on inverter.

Types of Inverters:

The inverters are classified into 3 types on the basis of outputs they offer: pure sine wave, modified sine wave, and square wave inverters.

1.Pure Sine Wave Inverters:

The pure sine wave inverters supply current from the battery in a reliable and cleaner form. It is very similar to the pattern offered by normal wall sockets. The output offered by it is in a sine waveform that is very similar to that of a utility supply. This is definitely a plus point as all the appliances are designed to work on this sine wave pattern only.

These inverters are the best choice for those who wish to use the inverter for high-powered appliances including air cooler, microwave, or TV. They provide efficiency and consume less power. The pure sine wave inverters are reliable and very effective for running multiple devices as they adjust the voltage according to the power requirements. Even though these inverters are a bit costly, they are an ideal choice that can take heavy loads.

2. Modified Sine Wave Inverters:

A modified sine wave inverter does not offer a very smooth transition as that of a pure sine wave inverter and takes a brief pause before shifting the phases from positive to negative.

The functioning of a modified sine wave inverter is more like square, but a little bit more complex than the square wave inverters. These inverters work well with many appliances, however, in some cases; they might affect the efficiency of the appliances too. This might result into a humming/buzzing sound or dimmer lights. 

These inverters are an ideal choice for devices with resistive loads and for those that do not require any start-up surge. When compared to the pure sine wave inverters, these models are a bit cheaper.

3. Square Wave Inverters:

These types of inverters generate a waveform in square shape. As far as the performance is concerned, these are least efficient when compared to other types of inverters. However, with the square wave inverters, you can allow the modest devices that have universal motors to work. One of the disadvantages of these inverters is they are very noisy. 

Important things to consider while buying an inverter

Mentioned below are 3 important things that you should consider before buying an inverter:

  • Power requirement
  • Capacity of the inverter
  • Battery size

1.Understand the power requirement

Before buying an inverter, it is very important to check and understand your requirements. You should decide in advance how many appliances you want to connect with the inverter for power backup. After finalizing this, you can calculate your total power consumption.

To calculate this, you should know the wattage of all the appliances so that you can get the idea about how much capacity inverter is needed. Here is the general power consumption of few common appliances:

AppliancesPower Requirement (in Watts)
LED Bulb7
Tube Light50
AC250 - 300
Mixer Grinder350
Induction Cooker1000 - 1500

As an example, if you wish to use 2 CFL bulbs, 1 TV, 2 fans, and 1 tube light on the inverter, the total power required (based on the above table) would be:

2*25 + 1*120 + 2*80 + 1*50 = 380 watts

Thus, if this is your requirement, you can go with an inverter that can support 400 watts.

2. Find the capacity of the inverter

You can measure the capacity of an inverter in Volt-Amp (VA). In an ideal scenario, the total wattage value (as calculated above) is equal to the VA value. But, due to the “Power Factor”, it is not generally the same.

The power factor is considered as a measure of how effectively the incoming power is used in the electric system. It is also defined as the ratio of Real power to Apparent power (working power to total power).

The real power (measured in kW) is the amount of power required to power the equipment so that it can start performing.

On the other hand, the reactive power (kVAR) is the amount of power required by equipment such as transformers or motors to create a magnetic field so that it can enable the work that needs to be done. It is important to operate few equipment’s but you don’t see any outcome for its use.

For a residential purpose, the power factor should be around 0.7 to 0.8 where 0.7 is considered as a safe number and 0.8 is an economical assumption. Thus, total VA is the total load (in watts) divided by 0.8.

In this case, the VA value would be:

380/0.8 = 475 VA

Now, you might not get an inverter that offers a VA value of exactly 475VA. Thus, you can select an inverter that offers a VA value that is more than 475. Thus, 500 or 700VA can be a safer assumption in this case.

3. Calculate the required battery size

You should always know the size of the battery that you need. If you choose an incompatible battery size, the inverter might not be able to deliver the best results to you.

The capacity or the size of the battery is measured in Amp-Hour (Ah) which refers to the amount of current that a battery can provide for a specific time period.

For example, a 1000Ah battery can supply 1000 amp current in an hour. Or it can also supply 500 amp of current for 2 hours. You can calculate the battery size using the following formula:

Inverter’s VA rating X usage time (in hours) / input voltage = Battery size

Now, let’s say you wish to use a 500 VA inverter for 6 hours backup, the required battery size can be calculated as follows: 

500 VA X 6 hours = 3000VAh

A regular inverter battery offers an input of 12 volts. Thus, the Ah value can be calculated as:

3000VAh/12V = 250 Ah

If you go to buy a battery for your inverter, one of the first things that you must look for is the Ah value. This represents how much energy can a battery store. The Ah values of any typical battery of the inverter are as follows: 100 Ah, 120 Ah, 180 Ah, 200 Ah, 250 Ah, and so on. Thus, in this example, you will need a 250 Ah battery for the ideal support.

There are 3 types of batteries available in the market:

  • Flat plate batteries
  • Tubular batteries
  • Maintenance Free batteries

Out of all the 3 types, the Tubular Batteries are considered as the best choice of batteries for inverters. Even though they are a bit costlier than the Flat Plate batteries, the Tubular batteries offer long-lasting performance. The lifespan of Maintenance Free batteries is 4-5 years whereas the battery life Tubular Batteries is 7-8 hours.

One more factor that helps in the long-lasting performance of the batteries is whether it is topped or filled with distilled or RO water frequently or not. You can read this in detail here: link of the article.

Factors to consider before buying an inverter

Mentioned below are a few parameters that you must keep under consideration so that you can use the inverter wisely:

1. Bypass Switch

With an inverter, there is always a possibility that the inverter might face issues like a blown fuse or power overload, etc. These issues can affect the functioning of the inverter and this is where a bypass switch can turn out to be useful.

The Bypass switch allows the users to by-pass the normal functioning of the inverter by using the power from the main electric grid. Here, the power does not pass through the inverter and hence, this gives you some time to resolve the issue. The bypass switch allows you to do so without causing any interruption in the power supply to your home.

2. Brand

It is always a wise decision to select an inverter from a well-known brand rather than going for a local brand. A branded product assures you about the quality, safety features, and the desired warranty. Above all, it also provides great customer support to help you deal with any issues. They provide after-sale service and help you with any unexpected problems.Batteries or inverters of local brands fail to do so and thus, it is not suggested to buy them.

3. Price

A regular inverter costs between Rs. 5000 – 8000. The pricing depends on the brand, technical specifications and the feature it offers. While some brands of inverters are more efficient than other brands, the efficiency depends on the amount of energy lost in the process of energy conversion from DC to AC. Thus, the most efficient inverters are a bit costlier than the others.

The inverters that offer higher VA ratings are costlier as they are capable of handling heavy appliances such as fridge, microwave, etc.

Other things to consider before buying an inverter

Here are some other factors that play a major role in deciding the best inverter for your home.

1.Wiring of the house

Before buying an inverter, it is very important to check the wiring. You can consult an electrician and check whether the wiring of the house supports the backup facility. Providing an electric backup to all the electrical appliances of the house is not a difficult issue.

However, if you wish to exclude a few appliances such as AC or fridge from the backup, you must consult an electrician and get these appliances isolated before buying the inverter.

2. Inverter trolley

Placing the inverter at a safe and correct position is very important. It should always be installed on the ground level. Since these are heavier appliances, it is good to buy a trolley so that you can place the inverter and the battery together over it.

You should place it near the main electric supply to avoid unnecessary wires hanging all over the place.

3. Earthing and other issues

It is very essential to check whether your house has proper earthing facilities or not. This will help in preventing unwanted accidents such as short-circuits or electrocution. Never touch the battery terminals or the inverter with wet hands and keep it out of the reach of children and pets.

Safety measures that you must take while operating the inverter

Even though buying an inverter solves all the power supply issues at your home, you must take proper measures to maintain the device properly. It helps in increasing the lifespan of the inverter and the battery. Here are some tips that you must follow:

  • The flat and tubular batteries need frequent replenishment of distilled water. This replenishment period varies between 1 – 3 months, depending on the type of the battery or the usage of the inverter. You must make a note and set a reminder for the next refilling.
  • Place the inverter on a flat surface either vertically or horizontally.
  • As water is a good conductor of electricity, touching the inverter with wet hands might lead to accidents such as an electric shock.
  • An ideal temperature to place the inverter in safe limits is 50-80 degrees Celsius. Avoid keeping it under direct sunlight or near heating vents.
  • Don’t place the inverter in a closed area and make sure it well-ventilated while in use.
  • There is a fan located inside the inverter. Its placement should be in such a way that the fans should have enough space to blow out the heat. Make sure you don’t cover the fan and let the heat flow out.
  • There are chances that the socket connection can form rust due to humidity or due to occasional spilling out of water. The rusting can affect the connections. Thus, to prevent rusting, you can apply grease over the connections.
  • In the case of corrosion, use a mixture of water and baking soda to remove the rust.
  • To rejuvenate the electrolyte solution, discharge the battery completely at least once in a month.
  • Avoid connecting appliances that use heavy loads such as a water heater or fridge to prevent overloading.
  • Wipe the dust over the inverter and battery using a microfiber cloth at regular intervals.
  • Don’t keep any flammable product near the inverter.

What is the difference between an Inverter and a UPS?

Even though the basic functionality and the architecture of both UPS and inverter are the same, there is a slight difference between both of them.

In case of power cut, while a UPS can switch to battery power within 3-5 milliseconds, an inverter takes a little bit longer and can switch in 100 milliseconds.

The choice between the inverter and UPS depends on how critical is the switching requirement to backup for the devices that you want to support. For example, for an appliance like a computer, even if there’s a gap of a few milliseconds, there are chances that you might lose the data.

Unlike UPS, an inverter does not have an in-built battery. The inverter has to draw power from an external battery and then it makes the transformation from DC to AC. Thus, it takes a little longer to send the power from the battery to the appliances via the main supply.

Another difference between both of them is with UPS, the appliances connected directly through the plug holes whereas this is not the case with the inverters. An inverter uses the main supply line to send power from battery to the devices. Thus, this causes a relative delay when compared to UPS.

UPS offers 2 options – online UPS and offline UPS. The online UPS draws a continuous power supply from the battery, irrespective of the fact whether the power is available from the main line or not. Thus, in case of a power cut, you might not notice any difference. The offline UPS draws power from the battery only when there is a power cut and in the remaining times, it draws power from the main line.

Frequently Asked Questions?

1. Can I keep the inverter in my bedroom?

It is suggested to keep the inverter in open spaces such as a balcony or near the window as it emits hydrogen fumes and other gases in smaller quantities. For proper ventilation, you must keep it in places so that you don’t end up inhaling them. Thus, we don’t suggest you to keep the inverter in your bedroom.

2. Why does the inverter at my house makes beep sound continuously?

The most common reason for this continuous beeping is it is an indication that the battery level of the inverter is low and it’s time to charge it as soon as possible.
Another reason can be capacity overload. This is an indication that you must try to remove the extra load by turning off a few appliances.

3. Can I turn off the inverter?

Turning off an inverter can discharge the battery completely and it might not be able to provide you a backup when there is no power. This is why you should not turn off the inverter.
The only time when you should switch it off is while checking or while refilling the electrolyte or distilled water. Once you are done with refilling, remember to turn it on again.

4. Do you get batteries along with the inverter?

Even though all the inverters need batteries to work, you have to buy them separately. You can choose the size of the battery according to your requirements.

5. What is the difference between peak load and continuous load?

While making a decision about the required size of the power inverter, it is very essential to know the difference between continuous and peak power output.
The continuous load is the wattage at which the inverter runs. The peak load is the starting load that is necessary to get the device running. Almost all the inverters have a peak wattage twice to its continuous wattage.
If you have a fridge with a start up load of 15 amps and a continuous load of 5 amps, the peak surge rating can be calculated as follows:
5 amps X 120 volts = 600 watts continuous load
15 amps * 120 volts = 1800 watts starting load
In this scenario, you will have to look for an inverter with a peak surge rating that is greater than 1800 watts.

6. What is a solar inverter?

A solar inverter converts the DC output of a PV (photovoltaic) solar panel into AC in order to provide an electric backup.

7. Do solar inverters come with solar power port?

To use the solar inverter, you will have to add the solar converter or solar charge controller to the inverter. It is generally not suggested for home usage and even if you intend to do so, check if the present model of the inverter that you have supports it or not.

8. How to know if the inverter is fully charged?

You can check the status of charging in the indicator display. Some models of inverters provide overcharging protection. Some models even have alarms to show that the inverter is fully charged.

9. How can I install the inverter in my home?

Even though many brands of inverters provide service warranty, they don’t usually help you with the installation. You can get this done with the help of an electrician.

10. The inverter at my place makes a sound once while it is in use. Is it normal?

Yes. This is an indication that the inverter is converting the current from the battery.

11. Why Should I Buy An Inverter?

In India, the power cut is a common phenomenon. When there is no power, the electrical appliances with which we surround ourselves will not work. Therefore, it is highly inconvenient from all aspects starting from basic living without light and fan to professional working without computers and other gadgets. An inverter with a battery can provide an instant solution to power cut by running all the electric appliances by drawing current from the battery after transforming DC to AC voltage.

Therefore, you can enjoy the benefits of the appliances even without the presence of the main power supply. Moreover, the appliances will not crash or shut down momentarily as the switchover time is in milliseconds. Not just that, the modern inverters also act as voltage stabilizers, and they will protect the sensitive appliances from voltage fluctuations and sudden surge.

12. Which Are The Best Inverter Brands In India?

Due to frequent power cut complaint in suburban and rural areas, inverters have become a must for every home. That is why there are so many brands available selling inverters with different features and specifications. But it is always better to buy from popular brands as the product will have standard features, high efficiency, superior quality, and greater durability.
Some of the best inverter brands in the Indian market are as follows:
Luminous – Known for intelligent and feature-rich inverters.
Exide – Known for its highly durable batteries as well as heavy-duty inverters.
Microtek – Known for its inverters which also act as UPS.
Sukam – Known for its hybrid solar inverters.

13. How Much Does An Inverter Cost?

The cost of the inverter depends on its brand, its features, and as well as its technical specifications. The inverters that are more efficient which means there is less energy loss in the conversion from DC to AC, they will naturally be more expensive. The inverters with higher VA rating will be more costly as they can handle heavy appliances like microwave, refrigerator, computer and likewise. In general, for domestic usage, the cost of the inverters will vary from 5000 to 6000 with standard features. With smart and advanced features, the price can go up to around 8000.

14. What Is The Different Between Inverter and UPS?

The basic difference between an inverter and a UPS lies in the switch-over time when there is a power cut. The switch-over time is the time taken by the device to supply current to the home appliances when there is load-shedding. A UPS takes minimal time which ranges in between 3 to 5 milliseconds. On the other hand, the standalone inverter takes 10 to 100 milliseconds. This relatively high delay in the inverter is acceptable for household appliances such as fans and lights. But for sensitive devices such as computers, this delay may lead to system crash and rebooting and in the process, loss of data.
This delay in an inverter is due to the reason that a standalone inverter does not come with an inbuilt battery, unlike a UPS. Therefore, it has to draw power from an external battery and make the transformation from DC to AC. Secondly, in a UPS, the devices or appliances are connected directly through plug holes, but it is not the case with an inverter. The inverter uses the main supply line for sending the power from the battery to the appliances and hence, there is a relative delay in comparison to a UPS.

15. Which Appliance Can I Run On My Inverter?

You can run almost all common appliances using an inverter, but it entirely depends on the rating of your inverter. In general, regular home inverters are suitable or running lights, fans, cooler, and TV. But if there are heavy appliances such as computers, refrigerators, microwave, and others, you need an inverter and a battery of higher rating than the combined load of all the appliances.

16. What Precautions Should One Take With Operating An Inverter?

There are a few points to have to keep in mind while operating an inverter, and they are as follows.
* Do not place the inverter near a window from where direct sunlight that hit the inverter
* Do not place it near a heat vent or any other appliance that gives out hot area.
* Do not place the battery near flammable material.
* Make sure that the inverter comes in contact with water or moisture.
* Place the inverter in a cool and dry place which could be well above ground so that kids do not touch.
* Do not touch the inverter with wet hands because not every inverter has a shockproof body.
* Clean the inverter with a microfiber cloth from time to time.
* Check the water level indicator of the battery from time to time and do the needful when required.

17. What Are the Various Types Of Batteries Available?

It is important to know about the types of batteries available in the market because, with an inverter, you have to buy an external battery. Not all inverters are compatible with every type of battery.
Lead Acid Battery:
It is the most common type of battery used, and it has the capability to generate a large amount of power. However, there is a need for regular maintenance such as the distilled water needs to be recycled quite frequently. Not just that, it needs to be placed in an area with good ventilation option. It gets heated up as the load increases, and some give out harmful gases while charging and discharging. It is a commercial battery for inverters as they are economical and lightweight. The safety measures are not always up to the mark, and the lifespan is around 5 years.
Tubular Battery:
This is the most efficient inverter battery, and they have a longer lifespan which could be around 10 years. The maintenance is less than lead-acid batteries, but the design is quite complex. Due to a longer lifetime, they are costlier than lead-acid batteries, and if you have the budget, you should go for it.
Maintenance-Free Battery:
This is a relatively new type of battery where there is no headache of maintenance at all, and they are completely sealed. There is no need for topping up of electrolyte and distilled water. They are far safer than any other battery type as no human intervention is required. However, there are costlier, and the lifespan is lesser.

18. What Is The Normal Life Of An Inverter and Its Battery?.

The lifespan of an inverter can be multiple decades without any maintenance as such. However, it is the battery that needs to be changed at least once in ten years. In general, the tubular batteries last longer than flat place lead-acid batteries. The tubular ones can last from 8 to 10 years based on usage while the flat plate ones last from 3-5 years. However, it is totally dependent on the frequency of use (charging and discharging), the load (appliances connected to the inverter) as well as the maintenance of water level

19. Which Battery Is Best For Home Inverters?

To determine the best battery for your home inverter, you have to list down the appliances you want to run with the inverter battery. If there are too many appliances or heavy current-drawing appliances, you have to buy batteries of higher rating along with the inverter. Otherwise, you need to choose a tubular battery over a flat plate battery as the efficiency is more during conversion from DC to AC. Moreover, the lifespan is almost double than that of a flat plate lead-acid battery.

20. What Are The Other Applications Of Inverters?

Apart from running appliances during a power cut, an inverter is used in multiple other applications. For example, it is used in solar power generation as it converts the generated DC to AC for home usage. It also stores the excess power generated in the battery for future use. Similarly, you will find miniature inverter in UPS where it increases the efficiency of the UPS and helps in faster charging of the internal battery of the UPS.
