Why is My Inverter Making Noise? (9+ Reasons You Should Know)

Why is my inverter making noise: Over the years, people have become pretty much thought about their way of life.

They have already integrated various types of electrical equipment like refrigerators, television sets, air conditioners, microwaves, etc. at their homes and workplaces to make their everyday life even more enjoyable and easygoing.

Anyways, among all of this equipment, power inverters might be the most significant one due to their outstanding properties. They ensure an uninterrupted power supply to the electronic devices when there is a power cut. 

However, they need proper maintenance to get an uninterrupted service year after year. But many of us often neglect this and encounter a lot of problems as a result. Amongst, the noise problem is the most common and annoying one.  

Today, we’ll find out the reasons for these noises along with their possible solutions.  So, let’s go over the following part to get a better understanding.

Why is my inverter making noise? 

There are a lot of reasons for what an inverter can create noises. Let’s get to know them with more details.

(1) Low Battery Condition

Low battery condition is one of the most obvious reasons for noise in inverters. When the charge of the battery is almost over, the inverter creates a beeping sound.

This is, in fact, an alarm for the owner to recharge the battery; the device is going to shut down within moments. In most cases, users get the alarm 2 minutes before shutting down.

However, you can adjust this according to your schedule. If the noise of your inverter emerges from this source, you just have to put it on charging as soon as possible. 

(2) Undersized Battery Cable

Undersized battery cable is another source of noise for inverters. When the cable of the inverter battery falls short than necessary, it creates a drop of voltage.

Consequently, a high-pitched alarming sound keeps ringing to notify of the immediate need of changing the battery cable. 

You can solve this problem in several ways. Among them, the most reliable solution would be calling a professional and replacing the cable as soon as possible.

However, if you want to remove the sound only, you can easily do so by turning off the UPS audible alarm tone on your inverter software. 

(3) Switching to Battery Power

There are two modes available in inverters such as the line mode and the battery mode. Users can choose any of them according to their requirements.

However, if the inverter, normally running on line mode, switches to battery mode, it creates an unstoppable beeping sound. So, whenever you experience such things with your inverter, make sure to solve them immediately. 

(4) A Decrease in the Battery Capacity

Like any other useful device, inverter batteries also lose their workability over time. When the capacity of the battery reduces to an alarming level, your inverter makes you informed of that with a strange alarm-like sound. In that case, you need to replace your inverter battery with a new one as early as possible. 

(5) Extra Load 

For every piece of electronic piece of equipment, there is a certain level of workability. It can never bear more load than its capacity if you don’t make any major upgrades. Likewise, your inverter also has a limitation of capability.

So, when you press more pressure,  it gives you an alarm to remove those extra loads. 

In this situation,  your first job is to disconnect the unnecessary devices from this backup system. Anyways, if all of your devices seem inevitable, you should switch to an inverter of perfect size and capacity to remove this sort of noise issue. 

(6) Failure in Self-testing

What we have discussed in our preceding parts are the most common reasons for the noise problem in inverters. Now, we are going to look at an uncommon reason for beeping sounds and that is the failure of inverters in self-testing. 

In general, an inverter launches its self-test every 2 weeks to check whether the battery is alright. If it fails to take a self-test, be sure that the battery is at its last stage. In that case, you have to change it within 2-4 weeks. 

(7) Effect of Some Appliances

Some appliances heavily affect the performance of inverters. They make the inverters create a loud hum or vibrating sound during the active period. 

This sound may seem like your inverter is almost going out of its capacity. But it actually doesn’t happen this time. 

Some of those appliances include dimmable light bulbs, hairdryers, hair straighteners, etc. Anyways, there is no serious effect of this noise on your inverter. But be a little bit conscious while using those things to avoid the irritation of this noise. 

(8) Low Solar Voltage 

This actually happens with solar inverters. When your solar inverter can’t absorb enough solar power to turn on the grid, you may find your inverter making a repeated clicking sound. In this situation, you should stop using your inverter until it gets sufficient solar voltage.

However, consulting with a professional is always a better option. 

(9) Dusty or Cogged Fan

Sometimes, you may go through a noisy sound due to the inconsistencies in your inverter fan. When you don’t clean your inverter fan for a long period, dust and debris accumulate and interrupt the natural rotation of the fan.

Ultimately, you experience such annoying noise. 

Clean your inverter fan on a regular basis to avoid this type of noise. If necessary, replace it or get it repaired by a serviceman. 

Final Thought

You just went through some exciting reasons why an inverter makes noises of different types. Besides, you have learned how to solve them with the most ease.

Now, it will be very easy for you to determine what’s causing your inverter’s noise and find out the most applicable solution for it. 

Anyways, you should go to an experienced serviceman in case any serious problem arises. Do your own research to get more possible reasons and solutions for the inverter noise problem.
