Is Stabilizer required for Inverter AC?

Is Stabilizer required for inverter AC? Of course, it is, and you need it more than ever before. The main reason being the massive voltage fluctuations that some areas of the county suffer from. As the name suggests, a stabilizer is a device used to prevent electronic devices from damages caused due to voltage fluctuations. However, when it comes to the Air conditioner, there are a few factors that need to be a checklist, these are:

  • The output voltage should be 220-250 Volts.
  • Should comprise of the time delay function.
  • Must include the cut-off protection.
  • Should have the Surge protection.

To answer the question, first, we must understand the difference between the inverter ac and the normal ac. The inverter AC maintains a fixed cooling range despite a varying voltage, something that will be stated on the machine itself. As for the normal AC cannot ‘cope-up with the fluctuating voltage, hence, it can damage severely. However, one might bear in mind that the fluctuations must lie well within the ‘range stated by the manufacturer’ for that particular model. Thus the simple answer to is stabilizer needed for inverter ac? The answer is ‘yes.

The Working: Stabilizer Is Required For Inverter AC

A normal AC would generally require a stable voltage range of 220-250 V. As for the need for the stabilizer for an inverter AC, as mentioned before, we do not require it if the fluctuations fall within the operating range. But, the dangers of voltage fluctuations beyond the operating range can occur. Therefore, it is recommended that you fix a stabilizer to your inverter AC.

We often wonder, is inverter ac need a stabilizer? Well, to truly understand, let us take a look at its working. The voltage in an inverter AC flows from under and over the system. These functions are termed as ‘boost’ and ‘Buck’ systems. The stabilizer is designed in a manner to recognise the incoming voltage. Also known as the utility voltage, the device boosts if the incoming voltage is less, making it up to the required voltage mark and thus, passes it onto the appliance that is connected. Likewise, in case of high voltage beyond the utility range, the stabilizer ‘mellows it down to the operation level and then allows it to pass on to the appliance. 

This is accomplished by an electronic circuit that comprises an inbuilt auto transformer. The ‘taps’ to the transformer are controlled by the high-quality electromagnetic relays that, in turn, can generate the required voltage range. In a nutshell, the stabilizer is a ‘buffer’ between your appliance and the unpredictable voltage fluctuation. 

What are the Benefits of the Voltage Stabilizer for AC?

There are more than one reasons to opt for the voltage stabilizer for AC. Let us take a look at some of these:

  • Stabilizers are required even for the in-built mechanism if the voltage fluctuation is beyond the operation range.
  • Protects your inverter AC and other home appliances from the sudden occurrence of damages.
  • Not many know this, but most electronic appliances perform better when under the stabilizer effect.
  • Is a perfect safety measure for the long-lasting life of your appliances and electronics.

Is Stabilizer Is Required For Inverter AC: Tips On Selecting The Right One

Once you have finally figured out that you require the stabilizer for your inverter AC, it is time to ensure you are equipped with the right information about it. So, here are a few pointers on what features to watch out for:


Once you have finally figured out that you require the stabilizer for your inverter AC, it is time to ensure you are equipped with the right information about it. So, here are a few pointers on what features to watch out for:

The Indicators

As we know, for inverter ac stabilizer is required; the indicator has a big role to play in it as well. This feature offers to allows the user to know about the voltage being supplied. The more advanced designs comprise LED indicators that are easy to read. 

The Time Delay System

This feature is especially beneficial for getting the required time to balance the current flow. This is highly recommended during short power cuts and comprises in-built Compressors.


This is the call of the day when most latest models are digitalised. This helps for easy reading and efficiency. The best part is that these latest models can easily adapt to some of the latest appliances. So, overall, you simply require to unplug and fix the stabilizer from one appliance to another as required.

The Overload Protection

This is one of the most important features to watch out for. The overload protection operates to switch off the output in case of the short circuit, thus making it safe for the appliance. As most stabilizers comprise of 3-5 year warranty, you can always enjoy services and replacements as required.

The Different Types of Stabilizers to Choose From

Sounds surprising, but there are types to the stabilizers. Here are the different stabilizer types and what they feature:
– Relay Type Voltage Stabilizer
– Servo Controlled Voltage Stabilizer
– Static Voltage Stabilizer

The differences in the types are based on their output range. It is also the output range that primarily determines the application of the certain type:

Low-Mid Range/Normal range:
200-240 V
Boost Buck:
20-35 V
High Range:
190-240 V
140-300 V
Boost Buck:
50-55 V

Is Stabilizer required for inverter AC?: The Conclusion

The stabilizer is a much-in-demand and recommended device that can make a lot of difference to the life and longevity of your electronic appliance. However, one must be sure to make the right selection, especially when it comes to the inverter AC requirements. As for the need and requirement, one must bear in mind that it is always a good idea to get a stabilizer as the unpredictability of the voltage fluctuation can be kept at bay.
