There is no straightforward answer to this question as it depends on your AC specification. You don’t need a stabilizer if your AC can work within a wide voltage range. If not, you need a stabilizer.
But before that, we need to know what a stabilizer does. Then only we can understand, if it is required for an Inverter AC or not.
What Does A Voltage Stabilizer Do?
A ” Voltage Stabilizer”, as the name suggests, stabilizes the output voltage when there is a fluctuation in the input voltage.
All appliances have a certain voltage range within which they can work. For example, In the United States, most appliances will work when the voltage is around 120V, whereas, in India, the requirement is 230V.
Now if you try to run an appliance built for 120V on a 230V power connection, it will burn out. That is where a voltage stabilizer comes into the picture.
A voltage stabilizer will always output a certain voltage required for your appliances irrespective of the input voltage.
For example, Voltas states that their AC needs a minimum of 100V to work. So if you feel that, in your home, the voltage can go below 100V ( For any reason), you need a stabilizer so that it always outputs 100V for your AC to work. As simple as that.
Most voltage stabilizer work in the range of 90V-300V. Beyond that limit, it will simply cut off the connection so that your appliance is saved.
Is Stabilizer Required For Inverter AC?
Now, the main question is, Is voltage stabilizer required for inverter AC?
If your AC can work in the voltage range of 90V-300V, then you don’t a stabilizer as the stabilizer would do the same job.
But in case, if your AC does not support that wide range of voltage, then you may need a stabilizer.
Personally, I recommend using a stabilizer, so that it can save your appliances in the worst-case power fluctuations. Because you don’t know when things can go drastically wrong.
The stabilizer acts as an extra safety cushion for your appliances. Or consider it as insurance for your appliances.
So, the answer to the question is that You may not need a stabilizer if your AC can work in the range of 90V-300V, but it is recommended to use a stabilizer to address major voltage fluctuations.
An inverter AC can save your power bills by “NOT” stopping your compressor frequently. That’s it.
Some people think that an Inverter AC can run even if there is no power. That is not true. Please read this article to know more about Inverter AC Vs Non-Inverter AC
Is Inverter Required For Voltas Inverter AC?
Voltas adjustable inverter ACs can work between 100V to 290V voltage range. So, normally you don’t need a stabilizer as even a very good stabilizer offers voltages in this range only.
But if you see that in your home, there is too much voltage fluctuation that may go below 90V or go above 290V, you may need a stabilizer.
As you can see in the above picture, Voltas has a stabilizer-free operation but it does not tell you if it has a stabilizer or not.
Is Inverter Required For Daikin Inverter AC?
High-end Dainkn ACs come with a feature called ” Stabilizer Inside Operation” that basically stabilizes the output voltage. In case, the fluctuation goes beyond the limit ( 130V-285V), it cuts off the power to save the AC.
As you can see below that Daikin ACs can operate between 160V-264V and it has an inbuilt stabilizer, so you don’t need to buy a separate stabilizer.
Is Inverter Required For Samsung Inverter AC?
Many Samsung Inverter ACs have a feature called ” Triple Protection Plus” that can handle voltage fluctuation between 80V to 450V.
The range is very wide. Even a very good stabilizer can not provide a wider voltage range than this. Most stabilizers work in the range of 90V to 300V only.
So if your Samsung Inverter AC has a ” Triple Protection Plus” feature, you don’t need a stabilizer.
Is Inverter Required For Bluestar Inverter AC?
Bluestar inverter ACs work in the voltage range of 160V to 270V and there is no mention of any safety switch if the voltage goes beyond that limit.
So, if you feel that the voltage fluctuation in your home can go beyond the limit specified above, you need a stabilizer.
Is Inverter Required For Lyod Inverter AC?
The working voltage range of most Lyod AC is 140V-280V. Lyod calls it a ” Stabilizer Free Operation“. In case the voltage fluctuation is beyond that limit, you need a stabilizer.
Is Inverter Required For LG Inverter AC?
LG does not specify if their AC has a safety switch that turns off the AC when the voltage fluctuation goes beyond the working limit. However, the LG AC’s voltage range is very wide between 120V to 290V.
Mostly, you don’t need a stabilizer, but in case the voltage fluctuation goes beyond that limit, you need a stabilizer.
Most ACs do not provide voltage range information unless you ask the salesperson for it. Even the salesperson may not know the range.
Don’t go by the names of the feature like ” Stabilizer Free Operation”. Look for the village range. If the voltage range is 90V-300V, you don’t need a stabilizer considering the fact your voltage fluctuation does not cross that limit.
“Stabilizer Free Operation does not mean that you don’t need a stabilizer. It means that the AC can work in a wider voltage range“
My personal recommendation would be to hook up a stabilizer for additional safety. Consider a stabilizer as an insurance policy that can save you from an inflated repair bill if something goes wrong.
Stabilizers are very cheap nowadays. Why do you want to take a chance?
