The average Indian household uses numerous electronic devices, most of which either need to be plugged in during use or need to be charged once the battery has run out. These devices require an AC (Alternating Current) in order to function. Therefore, to make use of these devices, a household needs to employ the use of an Inverter, which effectively converts the DC (Direct Current) that is supplied to the household. It is essential in the modern Indian home. The DC current is passed into the inverter via its battery which is then transmitted to the household circuit by the inverter.
Another major use of an inverter is in the backup of electronic devices. In the event of a power failure, an inverter is used to run the various electronic devises in the house. In India, a power failure or surge is not uncommon, which makes an inverter an indispensable part of the household. The battery stores energy which is later used in case of a power failure.
An inverter is usually used to back up the average fan and light system of a house. But in order to backup larger appliances one must purchase and use an inverter with more capacity. The crucial factor is the battery installed in the inverter, which is at the heart of all the function of the inverter. In order to back up larger appliances like an air conditioner or a geyser, an inverter with a larger battery capacity must be purchased.
During power surges or failures, an inverter is effectively able to provide you with the comforts of your appliances which would otherwise be unable to function. Inverters today often come with alarms, which are able to detect when battery is low or when other emergencies occur.
An important aspect of inverters is the filtration it provides. The cheaper ones provide little or no filter, producing a relatively simple, square wave, which is perfectly fine for a simple electronic appliance. But complicated appliances require a much finer sine wave, which makes the Inverter a little expensive. Therefore, the use of the inverter must be kept in mind while purchasing one.

Buying Guide – All You Need To Know About Inverters
For a new buyer, it could be quite overwhelming to select the best inverter they need for their home or office. For that, there is a requirement of enough knowledge about the product such as their types, understanding the specifications and requirements, making calculations to satisfy the requirements by select the right model and much more. Therefore, we are providing a complete buying guide for everyone to understand easily and pick the right inverter for home and office appliances.
What Is An Inverter?
In layman’s term, an inverter is a device that converts direct current (DC) into alternating current (AC) at any given voltage and frequency. The appliances at home run on AC and when the main power goes off, the inverter converts DC from the backup battery to AC to let the appliances run as usual without main electricity supply. This switchover time is almost negligible, and therefore, the appliances will not turn off when there is a power cut.
How To Find Which Inverter I Need For My Home?
VA stands for Volt-Ampere rating. In layman’s term, it is the voltage and current that the inverter is supplying to your home appliances. It is the unit used by the brands to rate their inverters, and as per the load of your appliances, you have to select high VA inverter accordingly. Therefore, it is important to know how to calculate this VA for the appliances you are going to connect to the inverter.
First, you have to note the efficiency or power factor of the inverter which varies from 0.6 to 0.8. This means the efficiency of an inverter varies from 60% to 80%. Second, you have to calculate the power required in watts by your appliances which is the total current requirement. Then you can calculate VA by dividing power required by power factor or efficiency.
VA = Power Required / Power Factor or Efficiency
Suppose, your appliances consume 540 watts of power and the efficiency of the inverter is considered to be 0.7.
Power of inverter (VA) = 540/0.7 = 770 VA.
Therefore, you have to buy an inverter of rating 800 VA or above to support all the appliances comfortably when the power goes off.
Here is a general list of common appliances and their power rating for easy calculation:
|Fan (Ceiling)||50-75 Watts|
|Fan (Table)||25-50 Watts|
|Computer (Desktop)||80-150 Watts|
|LCD TV (32″)||150 Watts|
|Tube Light (4 Feet)||40 Watts|
How To Find Which Battery I Need For My Inverter?
The standard inverter battery voltage is 12V. To calculate the capacity of the battery that you need to buy, you need power requirement that is the power consumed by the appliances and the backup hours you want.
Battery Capacity = Power Required x Backup Hours / Battery Voltage.
Suppose, your appliances consume 340 watts of power, battery voltage = 12V and the backup hours you want is 5 hours –
Battery Capacity = (340*5)/12 = 141Ah.
Therefore, a single battery of 150Ah will be enough. If you want, 110 hours of backup, you have to opt for double battery of 150Ah or 300Ah single battery. But be sure that the inverter is compatible with such a higher range of the battery capacity.
Factors To Keep In Mind While Buying An Inverter
As you can see from the above, there are too many technicalities as well as general parameters you have to keep in mind while buying an inverter so that you can run all the necessary appliances with your budget.
1. Type :
There are three types of inverters available in the market that are named after output waveform. They are square wave, modified sine wave, and pure sine wave inverter. The pure sine wave inverters are the best and the most efficient followed by modified sine wave ones and lastly the square wave ones.
- Square Wave Inverter – In terms of noise, the square wave ones make a lot of noise like humming sound and the appliances drawing power through it are less safe. However, there are a lot of buyers of this type because of the price tag which is the least among the three. It is suitable for running fans, lights, and such basic appliances but not the sensitive ones or heavy ones. The heat generation is high, and they need to be placed in a well-ventilated area. These can also reduce the normal lifespan of your battery.
- Pure Sine Wave Inverter – These are expensive and totally worth their price tags. The safety of the appliances is ensured to the maximum limit. The efficiency is on the higher limit of the range. The lifespan of the battery will improve significantly. The noise level is very low to such a degree that some are totally noiseless. The heat generation is moderate, and it is suitable for all sensitive and heavy appliances.
- Modified Sine Wave Inverter – There are many who cannot afford a pure sine wave inverter, and for them, this one is designed. All the aspects of this inverter type lie in the middle of the square wave and pure sine wave inverters. Surprisingly, the heat generation is the lowest among the three.
2. Compatibility :
This is probably the most important factor, and a normal buyer without much knowledge goes completely wrong. First of all, you have to calculate the power requirement of the appliances you want to connect to the inverter. Then calculate the VA of the inverter that you need to buy. Before buying, calculate the battery capacity required and make sure that the inverter you are about to buy, it does support the capacity of the battery. Not just that, you have to ensure that the inverter supports the type of battery you are about to buy such as flat-plate or tubular.
3. Versatility :
The modern inverters are just not simple inverters converting DC to AC. Instead, they are providing protection to the battery as well as the appliances. Most of them are working as voltage stabilizers providing protection against voltage fluctuation. Not just that, some are also acting like UPS so that the sensitive appliances do not crash while the switch-over takes place during a power cut.
In fact, some of them have dedicated plug holes to plug in the sensitive device and use the inverter as a UPS. Depending on your requirements like whether you are living in a place where voltage fluctuation is common, or you have sensitive appliances like computers or not, you should choose accordingly.
4. Protection :
Apart from the basic job of converting DC to AC, an inverter plays a major role in expanding the lifespan of a battery. It can provide protection from overloading from different appliances by resetting the load. Similarly, it can prevent undercharging and overcharging and shut down the battery when the charge reaches extremely low.
It can also prevent the discharge of the battery when there is no power cut for a long time. Furthermore, protection against short-circuiting with an inbuilt MCB is also available in some inverters. You have to check the features minutely to understand and depending on your budget, you should opt for them.
5. Dual Charging :
There are certain inverters available in the market that have dual charging facility. This means that you can charge the battery of the inverter through the main power supply as well as from solar power if you have the solar panels set up. This type of inverters is called hybrid solar inverters, and there are many brands like Sukam who are popularizing them. If you have solar panels already set up or you are planning to, you should go for it as they will save you a lot in your electricity bill in the long run.
6. Optimal Charging :
The modern inverters use various types of exclusive technologies and mechanisms so that the charging is optimal. Optimal does not always mean fast charging as fast charging consume more electricity. However, optimal charging implies fast charging when the battery charge is very low and normal charging when the charge is above 60% or more.
This is where the design part of the inverter comes into play. Almost every inverter comes with a display. Ideally speaking, it should show the backup time up to which the battery can support the appliances. However, only a few of them come with this parameter. Apart from that, it should show the current load so that in case of overload, you can switch off some appliances connected to it.
Most importantly, it should show the water level of the battery so that you can refill when it is low. Not just that, it should have an alarm system in place so that it can warn the buyer when the water level is low, the backup time is near its end, the load is over the limit and likewise. These are available in the modern and smart inverters, and naturally, their price will be on the higher side.
8. Warranty :
Even though an inverter is designed to last for a couple of decades, it is important that the inverter you are buying, it does come with a warranty for a few years. Generally, two years of warranty is provided within which you can find out if there is any defect in the inverter and get it rectified. The higher the warranty span, the better it is. This is true even for the battery you buy along with the inverter. The flat-plate ones provide one-two years warranty while the tubular ones provide as many as 2-5 years of warranty.
Apart from these, the presence of a bypass switch is important because some parts of the inverter can get damage in the long run. That should not hamper the electricity flowing to the appliances, and the bypass mechanism is placed exactly for that. Besides, you should ensure that the battery with a case to store it safely and securely.
Frequently Asked Questions?
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.
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.
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.
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.
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.
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.
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.
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.
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.
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
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.
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.
There are various types of inverters available in the market. Different inverters have different specifications, and you need to buy them as per your requirement. The above buying guide will surely help you to pick the one which matches your exact requirements.
Our recommendation from the list is the APC BX600C-IN UPS Inverter It is by far the best all rounder you can get at a decent price range. With 2 years of warranty, it is very user-friendly as it displays the remaining backup time and gives warning signals like low water level etc. Most importantly, it has an inbuilt MCB for any type of safety concerns.
There are other inverters in this last as well, which are equally potent and even better that Luminous in some areas. So, its better you go through our entire list and then make your purchase.
