Why Are Pure Sine Wave Inverters So Expensive?

If you’re living in an area where there are frequent power cuts, you need to buy an inverter to keep everything going smoothly.

An inverter can convert direct current electricity to alternating current to supply the grid station or stand-alone systems.

But wait! Why don’t you think for getting the pure sine wave inverter as it’s the best alternative to the grid power? Does this inverter run out of your budget? Is that really too expensive?

Period. The sine wave inverters are actually not expensive, but they hide a real power inside that’s worth every penny.

They provide you with the same-frequency power as you receive from the grid station. Sounds impressive! Right?

But wait, if you haven’t got one, check out some best 400-watt pure sine wave inverters enlisted by authenticpick.

Let’s know the secret behind the high cost of these inverters!

The Working of Pure Sine Wave Inverter

An inverter has to convert direct current to alternating current –the pure sine wave inverter uniquely does this job.

The working of this inverter is divided into three stages:

1.   Oscillator Stage

The working starts right when the inverter produces oscillating pulses with the help of a transistor circuit –most probably, an IC circuit.

The positive and negative voltage peaks charge the battery, and the oscillations continue all the way. However, after reaching a particular frequency value, these peaks are converted to inverter’s amplifier.

It’s an important step because the peaks have not reached the desired frequency to power anything up.

2.   Amplifier or Booster Stage

The pulses generated in the previous stage are finally boosted to reach an elevated current level –the desired value.

This stage ensures the boosted voltage can now convert the battery supply to the powerful electricity –ultimately powering your appliances.

During this, the inverter applies the amplified voltage to the transformer secondary winding output.

3.   Output Transformer Stage

The magnetic induction process takes place here that reduces the power supply to reach to lower desired AC output levels. Here, the inverter uses the two windings (primary and secondary) in the AC to the DC transformer.

It’s now the time when inverter will apply the low-level AC power into the secondary transformer windings, received during the amplifier stage.

The ultimate result is a stepped-up voltage that’s way better to power-up your home appliances. No matter how many power cuts you have, you can compensate for the power loss in the best possible way.

Benefits of the Pure Sine Wave Inverters

Let’s explore some real-time benefits of these inverters and the secret behind their high cost!

·      Less Power Consumption

There’s no exaggeration in saying that pure sine wave inverters really consume less power than the modified sine wave inverters.

You can blame the engineer’s mind for designing the square wave inverters later, but it’s something that you must know.

The square wave inverters come with greater Total Harmonic Distortion (THD) that depicts some higher unwanted distortions. These come with the pure signal and don’t even contribute to generating power, and these distortions get dissipated as heat energy.

Are you actually paying for the power you’re not even using?

Wait, wait, wait! There’s something for you! The pure sine wave inverters are actually free from such distortions –very low THDs, no doubt.

These inverters may cost you a little more initially, but they are highly efficient for cutting the electricity bills.

·      Clean Power Delivery

The pure sine wave inverters are the best alternative to the grid station, so far. They provide smooth AC power with fewer pulsations –precisely the same you receive from the power stations.

Most of the home appliances work on the pure AC power, so there’s nothing better you can power them up with when the grid is off.

·      Maintenance of Current and Voltage at Safe Levels

We know that we usually receive 230-240 volts AC power from the grid in our homes. However, the square wave inverters instead of keeping the voltage levels constant tend to fluctuate them.

When the voltage falls or rises than 230V, the ultimate result is immense harm to your costly electrical appliances.

Is the sine wave inverter more expensive than the combined loss you get from others inverters? Probably, not!

The pure sine wave inverters have been engineered to keep the voltage levels constant around 230V. They also save your appliances from crashing.

·      Noise-free Operation

 

Despite being highly practical, the pure sine wave inverters are easy on your appliances and ears. They just don’t over-burden the appliances and keep them calm and noiseless.

But wait, what causes the humming noise in appliances? When you’re using a square wave inverter, your electrical appliances produce a humming noise due to higher distortions.

The distortions are almost none in the pure sine wave inverters, making them practically run smooth and noiseless. The fluorescent lights, fan, TV, and amplifiers run well with them.

Plus, these inverters prevent the computer from crashing, monitors getting glitch, and print outs getting weird.

Besides that, the appliances remain cool when running on the pure sine wave instead of modified or square sine inverters.

Still not convinced?

The Pure Sine Wave Inverters are Actually Worth Every Penny!

The modified sine wave inverters maintain the shape of the wave square. The plateauing output peaks running on an MSW inverter demands a lot more power, hence additional heat loss.

You may find them cheap at first and effective a lot, but they are actually cutting their dues from your high electricity bills.

Finally comes the pure sine wave inverters that involve complex engineering and many more working details that demand a higher price.

They come with a microcontroller to generate PWM to approximate the sine wave appropriately. The transistors used in them are way more costly because they ensure faster and smoother operations.

The additional cost you’re going to pay will result in an ultimate peace of mind, no doubt.

With the technological advancements, the home appliances are getting way more complicated with advanced microprocessors. The PSW inverter is the only safe choice to deal with such sensitive items.

A lot of devices are dependent on a pure sine wave to time-up their operation. The inverter counts the frequency of how many the wave passes through the zero voltage –giving the vibes of an actual grid station.

The PSW inverters come equipped up with so many advanced components that are actually the reason behind its higher price tag. You get the AC power at par with that of the grid station. What else do you need, by the way?

Isn’t it a good idea to invest a little more to secure your sensitive electronics?

The Bottom Line

The pure sine wave inverters are an ingenious invention so far. They can enlighten your darks when there’s no light, let you continue with your everyday tasks, and many more.

People think that they are way more expensive than standard, modified or square counterparts. But they actually don’t realize the real power hidden inside.

Once you invest a little more in getting the best PSW inverter, you’re buying yourself peace of mind.

We have tried to explain the reason behind the high cost. It’s all the matter of how you think.
