Does Inverter AC Need Voltage Stabilizer

Are you a home owner concerned about ensuring your air conditioner is running efficiently? Choosing the right kind of AC for your Indian home is important to save money on energy bills. Inverter ACs arxe recommended nowadays due to their superior performance and lower electricity consumption rates, but Is Stabilizer required for Inverter AC an inverter AC need a voltage stabilizer as well?

Are stabilizers really needed for electrical and electronic equipment? This is a question which has been bugging consumers for the last two decades. We have been using stabilizers for TV, AC, and Refrigerators for a long time now and it has become an integral part of all these equipment.

The Inverter ACs that are available in the market today have built-in technology to save the AC from voltage fluctuations but what happens when the voltage goes above or beyond the permissible level? This is where stabilizers come into the picture and can be the savior of your AC. Read on to find out more about the Inverter AC technology and the need for voltage stabilizers for different AC brands.

Why Do We Need Voltage Stabilizers in Indian Homes

Stabilizers reduce the voltage to keep it within acceptable limits of the device when the voltage level is higher than the prescribed limit set by the equipment manufacturer. Devices that are sensitive to power fluctuations require stabilizer. Air conditioner inverters are vulnerable to power fluctuations.

There is a common notion that the inverter air conditioners do not need a stabilizer and that modern air conditioners have in-built mechanisms to protect against voltage fluctuations. But it is not completely true. These built-in mechanisms can only protect against variations within a certain range. When the fluctuations exceed that range it can affect the air conditioner and this is where the stabilizer comes into the picture.

Even if your region does not face much voltage fluctuations it is better to have a stabilizer installed so that it will help you protect your devices in unforeseen circumstances. It prevents device overheating and possible short circuits.

What is an Inverter AC?

Inverter technology is the latest technological development associated with electric motors in compressors. An inverter is used to control the speed of the compressor motor and continuously regulate the temperature. The microcontroller present inside can sense the ambient air temperature and adjust the compressor RPM accordingly.

Benefits of Inverter ACs

Compared to conventional air conditioners, inverter air conditioners have higher efficiency, longer component life, and no sudden load fluctuations. This makes the inverter AC unit quieter, reducing running costs and failures.

The inverter air conditioner operates very quietly since the compressor motor does not constantly turn on and off and maintains a low power level. In contrast to conventional split-ac versions, which consume more electricity regardless of demand, an inverter model regulates cooling and heating in an energy-efficient and seamless manner thus saving money.

Inverter AC cools the room at a considerably faster rate than its non-inverter counterpart as it operates at full power when the AC starts and gradually the power usage drops when it reaches the desired temperature.

Difference Between Inverter and Non-Inverter AC

The speed of a compressor’s motor is controlled by an inverter air conditioner in response to the temperature of the room. In order to conserve energy and the refrigerant needed to cool the air, inverter air conditioners slow down the speed of the compressor’s motor once a room is cool. In contrast, the motor in a non-inverter air conditioner only runs at full speed until the room is cool before turning off. In the process, the repeated on-and-off mechanism uses more energy and produces more noise. A non-inverter AC has lower initial costs. Because it can operate at a variable speed depending on the requirements, inverter air conditioners have low long-term operating costs.

Do Inverter ACs Need Stabilizer?

Because it regulates power fluctuations and prevents damage that cannot be repaired, an inverter AC requires a voltage stabilizer. Some people may think stabilizers are not necessary for inverter air conditioners. They are persuaded that current air conditioners have safeguards against voltage fluctuations. But the issue is these built-in mechanisms can only guard against changes within a predetermined range. Unless you have additional defenses like voltage stabilizers, you could lose your air conditioner if the fluctuations exceed that permissible range.

Again you might think that this problem is unimportant in locations where voltage does not exceed the permissible range. However, you are unable to control or anticipate the voltage changes in your area. You may lose your air conditioner before you realize your mistake, if a fault causes wildly fluctuating voltage. As a result, even though fluctuations are uncommon in your area, you should still use a stabilizer in case something unexpected happens.

When is a Stabilizer Not Needed?

Perhaps when a S-UTR compressor-type mechanism is included with some ACs to regulate fluctuations, you might not need a stabilizer. However, it is unable to control the fluctuation when it exceeds its range.

Do Hitachi Inverter ACs Require a Stabilizer?

Hitachi promises a voltage range of 160-255 Volts for normal ACs. And this type may need a stabilizer. Whereas the latest Kashikoi models have wider voltage range and may work fine without a stabilizer. If there are more fluctuations in your area and your AC needs a stabilizer you can go for the Hitachi Ryokuu 1.5 Ton 140V-280V Double Booster Voltage Stabilizer.

Final Thoughts

The range of voltage varies with brand and most of the Inverter ACs do not have the need to have a stabilizer. However, voltage fluctuations in India can be frequent and you may not know when the voltage drops or peaks. When this happens it will definitely affect the appliances at home and AC is costlier compared to a TV or a Refrigerator and thus it will not hurt to have an extra protection for these devices.

Another important thing to note is to find the right stabilizer for the Inverter AC. You must check if the voltage range of the stabilizer suits the AC in both high and low voltages. Whatever the scenario be, it is better to spend a few extra bucks on the stabilizer to safeguard the much costlier appliance.
