Does inverter ac need stabilizer in 2023? - Buyerguide (2023)

Does inverter AC need a stabilizer? In other words, is a stabilizer required for inverter ac?

No, Inverter AC does not need a stabilizer as they come with the in-built one. However, you should check out the manual to determine whether your AC has a built-in stabilizer or S- UTR compressor of enough voltage range to protect the unit.

Still, it is advised to have an external stabilizer for backup purposes.

Even after knowing the answer to the question of whether an inverter Air conditioner requires an external stabilizer, there is a little more info that I would like to share with you, which will help you further. Such as –

  • What are the types of stabilizers?
  • How do stabilizers work?
  • Does inverter air conditioner require a stabilizer?
  • Is it safe to use ac without a stabilizer?

What are the types of stabilizers?

There are two types of stabilizers- Relay stabilizers and Servo Stabilizers.

Relay stabilizers are suitable for appliances that do not need much power, while when you consider large and heavy power-consuming appliances, you should use the Servo stabilizers.

The other feature of the relay stabilizers is a faster response in stabilizing the AC’s voltage without cutting off the power supplies. They can also decrease or increase the Air conditioner’s voltage one level from the normal voltage.

In the case of the Servo stabilizer, it is a somewhat different game altogether. They can increase or decrease your Air conditioner voltages as much as you require, but their responses are pretty slow compared to the Relay stabilizers.

How do stabilizers work?

A stabilizer’s primary work is to maintain the Voltage frequency to run the heavy electrical appliances such as Air conditioners.

Hence the stabilizer, along with the transformer connected to the different switching relays’ configuration, and if the voltage drops, it adds the voltage, or if in case of voltage rise, it will subtract the voltage for the working of your Air conditioner.

What are the types of the Air conditioner?

There are different types of air conditioners which are available in the market mentioned below-

  • Central ACs,
  • Smart ACs,
  • Duel Fuel ACs,
  • Portable ACs, and
  • Inverter ACs.

When considering the Central AC, portable AC, smart AC, and Hybrid AC, they generally use the stabilizers mentioned above – Relay and Servo Stabilizers.

Now the question comes: what about the Inverter AC. Or in other words, Does inverter air conditioner need an external stabilizer?

Does inverter AC need a stabilizer?

Before I answer your question about whether inverter ac needs a stabilizer, I must first address some of the basic information related to the topic.

There are different regions where the climate is stable. In other words, less electricity is cut off or minor voltage malfunctions. Then comes the areas where voltage malfunction is quite usual.

One more point to be noted is that- every Air conditioner has an in-built stabilizer, which can withstand some of the basic levels of voltage malfunction. Still, it is even advised to use an external stabilizer for the extreme voltage drops and ups.

Now, if you belong to the area where the voltage drops are pretty rare, you might not need a stabilizer, but in other cases, I highly recommend you connect a stabilizer to your AC.

Let me talk specifically about whether an inverter air conditioner needs an external stabilizer?

Does inverter AC have an inbuilt stabilizer?

Generally, Inverter Ac does not require stabilizers, as it contains in-built S- UTR compressors, providing a similar feature to the external stabilizer. However, it is advised to have an external one as a backup.

In short, inverter ac can run without a stabilizer, but you should have an external stabilizer for security purposes.

Now let me talk about the different Inverter AC brands that require stabilizers.

Does Voltas inverter AC need a stabilizer?

If the voltage frequency is below or under 100 Volts in your area, you can quickly run your Voltas inverter AC without any issue.

Does Daikin inverter ac need a stabilizer?

No Daikin inverter Ac does not need a stabilizer. According to the Daikin company, the inverter includes an in-built stabilizer that cuts off the power in case of a voltage malfunction.

Does a blue star inverter AC need a stabilizer?

No, Blue star inverter AC does not require an external stabilizer. Per their manual, it has a built-in stabilizer that can withstand the voltage range of 160 to 270 Volts.

Does Hitachi inverter AC need a stabilizer?

Yes, Hitachi inverter AC needs a stabilizer to work. If the voltage drops to its minimum range, your air conditioner will not work. You have to connect the external stabilizer with the Hitachi inverter AC.

Does Whirlpool inverter AC need a stabilizer?

You will need to connect an external stabilizer to use your Whirlpool inverter AC.

Does Samsung inverter AC need a stabilizer?

No, Samsung inverter AC does not require an external stabilizer as it comes with the S-UTR Compressor, which provides your AC with a wide range of voltage fluctuations.

Does Panasonic inverter ac need a stabilizer?

No, the latest Panasonic inverter AC does not require an external stabilizer to do its task.

Does dual inverter AC need a stabilizer?

Dual Inverter AC does not need a stabilizer as it can run on a specific range of voltage between 145 to 290 Volts. If you live in an area where voltage even fluctuates beyond this range, then it is recommended to have an external stabilizer for a safe option.

Note- You can use an ampere meter to measure your Home’s voltage.

Is it safe to use ac without a stabilizer?

Yes, you can use your Air conditioner without a stabilizer, but it depends on your chosen brand and the features you will get from your device.

As I mentioned, some of the brands above tell us some require stabilizers while others do not.

How Many kVA Voltage Stabilizers are Required?

You might not know that, but when you look for the stabilizers, you will find different stabilizers of different sizes measured in kVA value (kilovolt-ampere).

It was said that always have a stabilizer with up to 20-25% more power or wattage capacity than the appliance you will use along with your stabilizer.

Now the question comes how you will find out the wattage of your Air conditioner?

Don’t worry when you look for your unit, and you will find out the wattage consumption of your Air conditioner.

Voltage Stabilizer Required for different inverter ACs.

TonnageMax WattageMax kVA
1 Ton1300 Watts or 1.3 kW1.6 kVA
1.5 Ton1900 Watts or 1.9 kW2.4 kVA
2 Ton2500 Watts or 2.5 kW3 kVA

Is Inverter Technology Energy-Efficient?

When you compare the Normal or Non-inverter AC and the Inverter AC, you will get the answer regarding the energy efficiency. It is somewhat similar to the Inverter Technology works in the refrigerators.

In the standard AC, the compressor only turns on long enough to lower the temperature of your room as per the requirement and then shuts off.

When you consider the inverter AC, it is just the opposite. An inverter AC compressor works 24 hours. But due to the inverter technology, the AC can regulate the compressor’s power consumption, making it more efficient in terms of power usage compared to the Normal or Non-inverter AC.

In short, inverter AC will save up to 30% more power than the non-inverter AC in the long run.

Now the question comes why I am explaining this to you? What benefit will you have?

Let me explain. If you have an inverter AC, then it will save power. Some brands offer an in-built stabilizer, which means you do not need an external stabilizer that saves some of the extra power, unlike the Non-inverter AC.

After all, the external stabilizer will also consume some power, showing a rise in your electricity bills.
