Can you run Subwoofers on Home Inverters? (Answered)

In most homes, people install inverters as an alternate source of power to run different electronic appliances including the sound systems.

Inverters supply power with the help of batteries in the event of power cuts that last longer.

For a standard home theater systems, the most important factor to consider is the amount of power your subwoofer consumes during function.

Accordingly, you will be able to determine if the inverter is capable of supplying the right amount of power (voltage) to the unit.

In this article, we will discuss the powering options for your subwoofer using the right inverters along with answers to some frequently asked questions.

Can you power a subwoofer through home inverters?

Can you run subwoofers on inverter power

Yes, a subwoofer can be powered using home inverters as long as their power specifications meet their demands. Inverters use batteries to store power, and batteries supply DC current which is converted to AC by the powered inverters.

Car subs typically run on a 12V current, regular electrical outlets in homes deliver 120V to 240V of current.

To convert the voltage most people make use of inverters so that they can power and use car subs at home.

In fact, most people install inverters at home as a backup source of power in the event of power cuts and surges.

These inverters need proper grounding and running additional electrical wirings to the outlets you want to use the inverter’s power.

In some cases, people run low-power-consuming applications including sound systems and televisions on inverters when needed.

The wattage of the home inverter needs to be on the higher side along with powerful batteries (higher amperage) to supply huge amounts of power to homes.

You can consult with a professional electrician to install suitable inverters considering your power requirements.

How long can you play subwoofers on inverters?

It completely depends on the size of the batteries connected to the inverters. The larger the size of the batteries, more the power they can store, and will ultimately let you play your sound system for a longer duration.

However, playing the subwoofer at higher volumes and at the lowest frequencies can lead to draining the inverter batteries more quickly.

Additionally, if you run multiple electronic appliances simultaneously can impact the battery’s longevity and reduce the run time.

Can you run a subwoofer with a small inverter?

Yes, you will be able to run a subwoofer with a small-sized inverter, however, if the subwoofer is too large then it’s better to avoid connecting them.

Larger subwoofers will run on bigger-sized amps, these amplifiers include capacitors in their circuitry.

A small-sized inverter will not be able to fill the capacitors with the required electrical charge they may need to hold.

Just like most subwoofer amplifiers that include a fuse as a protective element to prevent uneven electrical discharge, inverters also have them built-in.

A fuse in the subwoofer’s amp blows away in the event of an uneven power supply or due to excess heat and a blown subwoofer fuse will need replacement.

Similarly, if you put a lot of stress on inverters the built-in fuse will blow away and restrict the power supply.

Hence, it is always advised to use inverter power as a backup source and with limited and suitable applications.

Is it okay to power a large subwoofer on inverters?

To be on the safer side, avoid powering large subwoofer units and speakers on inverters.

However, if you are too eager about it, make sure to play the music at a lower volume and for shorter intervals.

Higher volumes will risk the inverter’s fuse from blowing or simply tripping off the entire unit.

How do sine wave inverters benefit sound?

Typically, inverters are available in two main types Sine wave inverters and Normal or Square wave inverters.

The job of the two is to convert DC power into AC and act as a backup source of power for applications that need electrical power to run.

However, sine wave inverters are more efficient and reliable than their counterparts.

Usually, we hear a humming noise coming out of TVs, fans, sound systems, etc., while they are powered by normal inverters.

This can be avoided by using sine wave inverters that can output smoother power.

Simply put, your appliances can get smoother and more stable power supplied by sine wave inverters compared to their counterparts.

This will help to minimize the possibilities of sound distortion or subwoofer clipping.

Finally, sine wave inverters tend to charge their connected batteries more quickly than ordinary inverters.

These inverters can be costlier than normal units, however, they will benefit your electronic applications in many ways including the sound system.

Do subwoofers run on inverters alongside regular power?

Typically, when there’s a power cut and return, the electrical supply automatically switches between the inverter and the main supplies.

Simply put, when there’s a power cut your sound system will continue to play without interruption as it will switch to inverter power.

Likewise, it will switch back to the main power source as the power returns.

The inverter will still be on and charge the batteries utilized during power cuts.

Should you place subwoofers closer to inverters?

It is not necessary to place subwoofers or speakers closer to inverters, instead place the subwoofers in their ideal spots. Make sure you have the inverter wires installed or running to the power outlets dedicated to your sound system.

Final Thoughts

Home inverters can be an ideal source of power supply to your home theatre system during power cuts or uneven fluctuations.

Just like most electronic appliances subwoofers and speakers can be powered through home outlets with inverter connections.

Make sure to compare the power requirements of the subwoofer before powering it with your home inverter.

If you are specifically hunting for an inverter for your home, you should opt for sine wave inverters especially to prevent humming or sound distortion in sound systems.
