Power inverters are remarkable devices. Beautifully designed and widely misunderstood. Although it’s no rocket science but then again, as much as I love it, the world of inverters can get slightly over the top!
So let’s get down to some basics.
The word ‘Inverter’. Does it strike a chord? When you read or hear about inverters, it’s not very difficult to relate! That is because staying in India, power cuts is no stranger to us. We are almost used to it now. And so invariably, an inverter comes into picture!
Almost every house in India has one! So does every factory, petrol pump, you name it!
Now can you imagine how widely used it is? Inverters, believe me is a luxury, an asset that most of us are quite unaware of. But ask the people living in remote areas. Areas where electricity is available for perhaps 2 hours in the day. They would re-emphasis this, the real need of inverters.
Inverter at a Glance:
And for my fellow newbies, here’s a brief understanding of inverters. There can be times when the electricity provided from the power stations is not available, and at those times we need a backup. Somewhere that we can store this electricity and use it later! We store this electricity in batteries. And this is why we need an inverter. To convert DC coming from batteries to AC supply which we use to run our appliances in times of need.
When we go in to buy our very own inverter for the first time, it’s essential to understand what exactly we are getting into.
It is a long term investment! Did you know? Inverters don’t wear out for almost 7 years in a row. So I suppose it gets down to this. We need to get it right the very first time! If you have ventured into the world of inverters, you may have come across three types that are widely used today:
- Square Wave Inverters
- Modified Sine Wave Inverters
- Pure Sine Wave Inverters.
Universal Fact and Related Myths
Pure Sine Wave inverters are the best. Period.
Obviously it is not easy for a common man to understand the core concepts related to inverters and so there are some expected misconceptions! Don’t sweat it. Read on, you’ll soon find out why! And like I said it’s no rocket science! Now when you get out there to buy your very first inverter, it can be a tough call. But this why we are here! Let’s find out the 3 most common myths about Pure Sine wave inverters!
Myth Number 1: It’s Expensive!!
Yes. Accepted. It’s the best isn’t it? But here’s the catch! It’s a onetime investment. By using a pure sine wave inverter we actually end up saving much more over time. Here’s how:
- Our appliances remain absolutely safe! They run better and using a pure sine wave inverter also prolongs their life!
- We end up saving a lot more on our monthly electricity bills!
This is because pure sine wave inverters, have a ‘true sine wave’ just like the one we receive from the power stations. So no losses and they are highly efficient!
Myth Number 2: All Appliances Do Not Require Pure Sine Wave Inverter
Not true! When we go in to buy an inverter we need to ensure that it is compatible with the load we want to run. It is common to hear that most appliances can run using a modified sine wave inverter.
First it is essential to understand that Modified Sine wave inverters have higher THD than Pure wave inverters. THD (Total Harmonic Distortion) very simply means higher distortions. Distortions are the unwanted part that we receive along with the pure signal. Because of these distortions MSWI produce a ‘humming noise’ and heats it our appliances. And also reduces their life. our appliances will operate with a reduced efficiency of 20% with a modified sine wave inverter, and they will wear off prematurely and eventually stops working.
Highly sensitive electronic instruments like Microwaves, Television sets, speed control motors are designed to work only on Pure Sine Wave so using anything else can permanently damage them, and its effects can be detrimental!
I rest my case.
Pure sine wave inverters are always the better choice.
Myth Number 3: Pure Sine Wave Inverter Are Not Readily Available
Here is some good news!
Pure sine wave inverters are widely being produced and are used commercially and non-commercially all over India. Reputed brands, always recommend the use of Pure sine wave inverters. Therefore they PSWI are manufactured at a large scale.
And hence they are certainly readily available!
But I would like to add a word of caution, that while a lot of production houses ‘claim’ to sell true sine wave inverters, they might be giving out a quasi-sine wave or a modified sine wave inverters at a higher price!
And therefore it is essential to make an informed choice and go in for reputed brand before buying your very own!
Talking of reputed inverter brands, how can we not credit Su-Kam for bringing in technology revolution in India’s power backup market. Su-Kam has made pure sine wave inverters that come in various sizes for various applications.
Check out India’s first smart home inverter/UPS by Su-Kam. Equipped with ATC Technology and DT-6S six stage charging, Falcon plus is THE BEST sine wave inverter that you can buy for you home. It is best suited for electrical load up to 1600VA.
This pure sine wave inverter by Su-Kam is perfect for homes or small businesses that have electrical load of up to 2.5kva.
If you your electrical load is more than 5kva, then Su-Kam’s Colossal series is right for you. This pure sine wave inverter is really colossal! It can take up to 100kva of electrical load.
