Is Stabilizer for Inverter AC Necessary [Explained]

You intend to get an inverter AC but unsure about the stabilizer. People often purchase inverter AC with a stabilizer. 

Is a stabilizer for inverter AC really necessary?

For inverter AC, a voltage stabilizer is essential since it balances voltage unbalance. And it also avoids an irreversible loss. Perhaps some stabilizers include a device (S-UTR compressor) to regulate swings. However, when the fluctuation surpasses its range, it is unable to manage it. 

It was only a brief explanation. If you have some spare time, you can read the article. It provides a thorough explanation of your query. 

What Precisely is an Inverter AC?

Air conditioners that are inverter and non-inverter are not the same thing. A traditional air conditioner works by absorbing the air in a room. 

And cooling it using evaporation before pushing it back out. A typical air conditioner’s operation is heavily reliant on the compressor.

But the compressor is not always turned on. When the air conditioner is first turned on, the unit will activate. Once it reaches desired temperature, the thermostats will notify the compressor, forcing it to turn off. 

It slightly sounds like the function of a Ritetemp thermostat. But the programming in a Ritetemp thermostat is different.

The noise you heard from your air conditioner after this step is caused by the fan. After that, it will stay turned on. When the temperature climbs over a certain threshold, the compressor kicks in.

What is the issue here?

Simply said, the compressor operates at full capacity at all times. If you put a non-inverter air conditioner meant for a huge room in a much smaller room. The compressor will continue to run at the same power. 

Despite the decline in space it is supposed to cool.

That’s where inverter technology comes into play. Just like inverter AC, you can also use a voltage stabilizer on TV.

 Inverter air conditioners will only consume as much electricity as is required to cool a specific space. To put it another way, they alter their operations to match the needs of each space. 

What is the Function of a Voltage Stabilizer?

A voltage stabilizer operates by increasing or bucking the voltage. When the voltage in your house exceeds the level allowed by the appliance’s supplier. In that case, the stabilizer will drop the voltage to maintain it within the proper range.

Voltage spikes are prevented from harming the device as a result of this. If the voltage entering your home falls below the required level, the stabilizer will increase it.

The Advantages and Disadvantages of Voltage Stabilizer for AC

Consumers who are well-informed recommend that you get a stabilizer for your inverter AC. Every equipment that is susceptible to power fluctuations necessitates the use of a stabilizer. 

Power fluctuations do not protect inverter air conditioners. They are more than capable of being destroyed by a voltage surge.

This will be avoided by using a stabilizer. Some contend that inverter air conditioners do not need stabilizers. They believe that current air conditioners are protected against voltage fluctuations via mechanisms.

But this is only partially correct. These built-in measures can only defend against variations within a certain range. 

If variations surpass the allowable range, you may lose your air conditioner. Until you have extra safeguards in place, such as those offered by voltage stabilizers.

Those people might argue that regions that don’t see severe variations aren’t affected by the issue discussed above. The ac built-in safeguards appear to be sufficient to keep them secure.

But you have no control or predictability over the swings in your location. If a malfunction causes the voltage to vary dramatically, you may lose your air conditioner. Before you discover your error. check your air conditioner wiring also at that time. 

As a result, even though your location seldom experiences oscillations. You should nevertheless use a stabilizer in case the unpredicted occurs. This is a more secure choice.

So, it secures your belongings against abrupt and unexpected voltage spikes or decreases. When it comes to most appliances, everyone recognizes the importance of a voltage stabilizer. 

Is it Possible to Connect AC Without a Stabilizer?

You may connect your AC without using a stabilizer if it has an S-UTR compressor. Their internal processes will maintain the power supply of the air conditioner constant.

What happens if the machine lacks an S-UTR compressor? Many manufacturers claim that their air conditioners feature built-in stabilizers. To put it another way, they don’t require an external stabilizer.

If you looking for S-UTR compressor, then you can try this one:


This product has good recommendations and also has a long-lasting effect. 

Those same manufacturers, though, usually add a cautionary remark in their instructions. Advising users their integrated stabilizer cannot ensure the safety of the AC of a dramatic variation in energy.

You can connect an alternating current without a stabilizer. Even with the built-in stabilizer, you’re still taking a significant risk. You will have more sense of peace with an additional stabilizer.

How Many kVA Voltage Stabilizers Are Necessary?

If you want your stabilizer to safeguard 1000 watt, you’ll need one with a 1.2kVA rating.

A stabilizer’s size is measured in kVA. The length of the stabilizer must be appropriate for the demands of your appliance. This entails calculating the appliance’s wattage rating. It is printed on a sticker that is fastened to the appliance. 

This will tell you how much weight the stabilizer must support. You should add 20% to the total wattage of your appliances. It will ensure that their power requirements match the kVA of the stabilizer.

Voltage Regulator Required for AC Inverter

In this chart, we will talk about different ton of AC inverter: 

TonnageMax WattageMax kVA
1 Ton1300 Watts1.6 kVA
1.5 Ton 1900 Watts2.4 kVA
2 Ton 2500 Watts3 kVA

Is Inverter Technology Efficient in Terms of Energy Consumption?

The compressor of a non-inverter AC runs long enough to reduce the heat to the appropriate scale. The compressor in an inverter air conditioner is constantly turned on. As a result, you’d think that inverter ACs utilize more power than non-inverter ACs.

But, the contrary is true. Yes, the compressor in an inverter air conditioner is constantly on. 

The inverter technology, on the other hand, controls the amount of electricity used by the compressor. That does not occur in non-inverter air conditioners. Their compressors continuously run at full capacity.

As a result, an inverter AC will minimize your home’s power usage over time. In rare circumstances, you may be able to save up to 30%.


Question: What is the distinction between an inverter and a stabilizer?

Answer: A stabilizer enables voltage to reach the TV up to 11 volts and transforms. Or it can dissipate the additional electricity as heat. An inverter, on the other hand, supplies enough electricity to the television while preserving the leftover power. 

Question: Is inverter air conditioning difficult to maintain? 

Answer: Because an inverter AC has more complicated circuitry and a greater number of moving components. The maintenance cost of an inverter AC will be higher. High operating costs in the case of frequent room opening and closure.

Question: Is a PCB warranty required for AC? 

Answer: A printed circuit board (PCB) is a type of circuit board. A PCB warranty guarantees a high-quality product that will not fail.The PCB warranty covers the energy and maintenance cost.
