Planning to buy an inverter? But cannot decide between sine wave and square wave inverter?
We are here to help you.
The debate over which is the best type of inverter, sine wave or square wave, is ongoing. so it can be tough to decide which is the best choice for you. The purpose of this blog post is to break down the differences between sine wave and square wave inverters, so that you can make an informed decision about which one is right for you.
But first what is an inverter? An inverter helps in converting DC electricity stored by the batteries to either Sine wave AC electricity or Square wave AC electricity, which is used by most household appliances. In comparison to the square wave inverter output, the sine wave inverter output is very similar to that of AC current and is pure, hence also called as pure sine wave inverter.
Sine wave vs. Square wave output : –
Sine wave inverter - generate a smooth, consistent power waveform, which is more closely aligned with the power provided by the grid. This makes them ideal for use with appliances that require a constant and precise flow of power, such as electronic equipment and appliances with motors.
Sine wave inverters are also better at handling surges in power and are less likely to cause damage to your appliances. They are typically more expensive than square wave inverters, but the extra cost can be worth it for appliances that need a stable power supply.
Square wave inverter - produce a more jagged power waveform than sine wave inverters. While this can be problematic for some appliances, it can also be a benefit for appliances that don't require a precise power flow.
Square wave inverters are typically less expensive than sine wave inverters, and they are better at handling surges in power. This makes them a good choice for appliances that are not as sensitive to power fluctuations.

Apart from the above two, there is also a Modified Sine Wave Inverter, the third type of inverter that functions somewhere between a sine wave and square wave inverter. Rather than producing a pure sine wave, it simulates a sine wave in its most important aspects. This allows most appliances to still be connected to the inverter without risk of overheating. It is used for simple appliances as there are lots of equipment that it cannot support.
However, if your priority lies in ensuring that your appliances are absolutely safe, the most secure way of ensuring the same is to invest in a pure sine wave inverter. This kind of inverter is preferred by those who want the benefits of a sine wave inverter, but money is a concern.
If you are looking to buy an efficient, compatible and long-lifepure sine wave inverter, then turn to Lento.We use pure sine wave technology in our inverters,UPS and power supplies.

FAQs about Sine Wave and Square Wave inverter-
- Which is better sine wave or square wave?
Sine wave inverters are more efficient than square wave inverters, when it comes to the conversion of DC to AC. This ensures that the power loss is minimised, due to greater efficiency. As a consequence, your electricity bill does not shoot up. This is an immediate benefit of using a sine wave inverter.
- What is the advantage of square wave?
The square signal is able to generate around 19% more force than the sinusoidal signal. As the frequency increase, the difference in forces starts decreasing until the frequency in which the DEP force of square signal is
equal to the DEP force of sinusoidal signal.
- Can an AC motor run on square wave?
The motor will smooth out the square wave to some extent but you're going to end up with a lot of harmonics and voltage spikes some of which the motor may not like at all.
- Which inverter is the best for home use?
- Lento Industries pvt. ltd - pure sine wave inverter
- Luminous
- ZunSolar
- V-Guard
- Luminous
- Microtek Hybrid Inverter
What size inverter do I need for my home?
The size you choose depends on the watts (or amps) of what you want to run (find the power consumption by referring to the specification plate on the appliance or tool). We recommend you buy a larger model than you think you'll need (at least 10% to 20% more than your largest load).
- What is the problem with square wave inverters?
Lower quality modified sine wave inverters are less efficient at 75-85%, while square wave ones are even less efficient. Lower the efficiency, more the losses in conversion, which will reflect in your electricity bill. The second reason is to do with the shape of the output wave.
- Where square wave inverters are used?
Square wave inverters are usually used to support motors alone. Sine wave inverters are used to support household appliances such as refrigerators ovens, computers, laptops, etc. Square wave inverters are less reliable and also unsafe to use for appliances.

5 How efficient are pure sine wave inverters?
How Efficient Are Pure Sine Wave Inverters? Most high quality pure sine wave inverters are rated at 90% to 95% efficiency. The lower quality modified sine wave inverters are much less efficient, between 75% to 85%.
6 What devices need pure sine wave?
Pure sine wave is always needed for a grid tie system. It is generally needed for newer LED TVs, CFL light bulbs, and inductive loads like brushless motors. Clocks and audio equipment will behave much better on a pure sine wave.
