Best Inverters in India 2021 – A Buying Guide
Inverter is a must have in many parts of India due to frequent power outages for various reasons. If not all, at least some of your electrical devices such as refrigerator, fans, computers, etc need to keep going. Inverter is a good alternative to the main power supply.
Good news is that there is no dearth of real good brand offerings in this segment, catering to various levels of power requirement. If you are seeking to buy one for yourself, you need to know few essentials regarding inverters in order to get the right fit for yourself.
All know that inverters convert low voltage direct current (DC) into high voltage alternate current (AC) for diverse domestic and industrial usages. But in order for them to be able to do so, they must first store energy. As it is, it cannot be stored as AC current simply because it cannot be saved. It is the DC current that can be saved. And it is saved in a battery. The work of the inverter is to covert the stored energy into usable AC current. It does so as per requirement.
Another thing that you need to know is the types of inverters available to you in the market and identifying the right one that your requirements call for. This is important in view of the fact that households vary in size, and the usage of units per day also differ considerably from house to house.
These are the types available to you in the market…
Square wave inverter: The square wave inverter is by no means as good as other options that are available to you. Though there are some products in the market that use this technology, in principle it is not quite suitable for all electrical and electronic appliances.
Sine wave inverter: Sine wave inverter produces the same energy that you receive from the mains. It perfectly suits all sorts of appliances used in domestic or industrial environment &
Modified sine wave inverter: Modified sine wave inverter produces electromagnetic waves that resemble both square and sine waves but actually they differ from both. It may not be accurate if we describe the waveform of modified sine wave inverter as square waves progressing in the same way that sine waves do but the description comes as close to the truth as it can.
From the customers’ point of view, all you need to look out for is the phrase sine wave inverter.
Uninterrupted Power Supply (UPS)
This is another term that you must look out for if you intend to have an inverter in order to keep your sensitive devices like computer going. There are inverters in the market that feature UPS. Therefore they are called inverter UPS.
The reason why this particular technology is a must for you is that it performs the task of rectification which is different from the work of an inverter. Rectification makes the current unidirectional by converting AC into DC. This process saves energy in the form of direct current. The work of an inverter is to convert DC into AC again.
The one big advantage of UPS is that it keeps the power supply uninterrupted. Sensitive systems, like computers, are prone to get damaged without UPS.
Inverter UPS with Digital Signal Processor
DSP has taken inverter UPS a step further from where the analogue based inverters were in past. It comes with a circuit that automates the operation of an inverter through
- PWM technology that digitally controls analog circuit, boosting control of power and conversion of the same
- A/D converter that converts voltage into digital signal and when it is required converts the digital signals into voltage through D/A converter
- CAN bus that facilitates communication between microcontrollers and devices connected to inverter without the intervention of a host computer
Such inverters, just like many other digital devices, have internal and external storage, serial ports, encoder, event timer, etc.
In spite of featuring such advancements, these devices are quite cost-effective. They come with excellent reverse voltage protection, reverse current protection, overload, etc protection.
Capacity of an Inverter
This is important for you to know before you buy one. It’s because you need a device that meets your energy requirements. How much energy you need? What devices you intend to run with it? The greater your need for consumption the greater the capacity you need to look out for in an inverter.
For instance, if you want an inverter that would power up to 3 tube lights (28W each), 3 CFL (20W), 3 fans (each up to 55W) and 1 mixer (up to 500W). Then, the total required wattage is 84+60+165+500=809W. In this case, if you have an inverter having the capacity of 1000W, then it will serve its purpose. Nevertheless, it will be good to have an inverter with greater capacity. But if you intend to run an appliance like an air conditioner, which are quite power hungry, then you certainly need something having the capacity above 3000W.The reason why you should look out for an inverter that has a capacity that is almost double the amount of energy that you need, is that no inverter is 100% efficient. It is bound to lose some of the energy in the process of conversion.
Battery of an Inverter
The inverter battery should have the capacity that is on par with the capacity of an inverter; because what the battery stores, the inverter converts into usable energy. There is a way you can find out the battery capacity. If your need calls for it, you may connect more batteries in a series.
Another thing, you need to know the battery backup time in order to find out how long a battery will last. In order to find it out, you need to know a few technical details such as the total amount of energy in Watts, the input voltage of the battery and its capacity in ampere hours. Once you get these info right, you can use this formula to get the battery backup time:
Battery backup time = battery capacity x input voltage / the total amount of energy in watts that you require
It is always good to have more battery backup time in order for the inverter to serve its purpose well.
Finally, there are many different types of batteries available for use with inverter. It is good to choose a device that supports batteries of all types. Because it is important, it is always stated in a product description whether it supports different types of batteries or not. These are the battery types that can go with an inverter:
- Lead acid battery: As the name suggests, water and acid are used in it. When it is charged, the acid is formed at the plate. This acid is thicker than water and so settles down at the bottom of the battery. On the contrary, when the battery is discharged, the acid in the electrolyte loses acidity and the positive and negative plates of lead are covered in lead sulfate. This covering of the lead sulfate on the surface of the leaden plates compromises chemical reaction that might take place on the surface of the plates. To put it in simple terms, the battery requires charging when such a situation takes place.
- Tubular plate battery: It is just another type of lead acid battery with the difference that it is larger in size and capacity than the lead acid battery that makes use of leaden plates instead of a grid consisting of tubular plates.
- Maintenance free battery: It is maintenance free in the sense that you don’t have to maintain the electrolyte concentration through periodic addition of pure water. As it is, when a battery is put to use, hydrogen is generated due to the chemical reaction in the battery. This hydrogen is released into the atmosphere. If it is not released, it would break open the battery cell. But due to the venting of hydrogen, the electrolyte in the battery gets thicker. In order to keep it thin, water needs to be added into it.
Backup Time Calculation
It is important for you to know how to calculate the backup time of a UPS inverter because you may want to have your inverter support all the equipment you want to run on it till the main power supply resumes. You can find it using this simple formula:
Battery voltage x battery Ah rating x inverter efficiency / total watts required by the equipment you intend to run with your UPS inverter.
There are some products that do make noise that is not negligible. It is good to read the customer reviews as well as product descriptions to know about the noise level of a product. The noise occurs due to the fan that is running in the inverter to cool it down.
Before buying anything it is advisable you know your energy requirement keeping one eye on the gadgets that you intend to run on your inverter and count the total load that they will put on the inverter. Your requirement determines your choice of inverters.
