Troubleshooting A Tesla Powerwall Noise

Troubleshooting A Tesla Powerwall Noise

Tesla Powerwall is one of the leading products in solar battery and has accelerated the future prospect of clean and reusable energy to the present. Of course, for its many pros, there’s always going to be a con or two, and the common con for the Tesla Powerwall is noise.  

Although there are only two elements of the Tesla Powerwall that make noise, if you are looking for a silent solar battery, then its occasional humming might be louder than you’d prefer. There are a few options to mitigate the overall noise of the Tesla Powerwall, from altering the room around it to managing how much power you are using at once.

Fitting your home with a source of energy that is not only renewable and environmentally clean but also allows you to have complete power independence is an ambition of many homeowners, especially considering the current climate crisis. If you’re interested in doing this, without the noise, keep reading.

Why Tesla Powerwalls Make Noise

The Tesla Powerwall is measured to make less than 50 decibels in sound, compared to a moderate conversation.

Although to some, this might typically be considered quiet, depending on where your battery is installed, this level of sound could be quite unpleasant. Most Powerwall owners that complain about noise compare the sound to a loud fan or humming noise. This is because of the components of the Powerwall that cause the sound.

The only parts of the Tesla Powerwall that make noise are its pump and a small fan that make up the battery’s cooling system.

When the battery has been expelling a great deal of energy for an extended period of time, the cooling system will turn on to prevent overheating. And so, owners will hear the pump and the fan running as they function.

As this is an integral part of the system, it cannot be removed or altered, but there are some basic solutions that might prevent or inhibit its noise level.

Possible Solutions for Quieting Tesla Powerwalls

The pros of owning a Tesla Powerwall outweigh the cons, but having excess noise is a deal-breaker for many. Thankfully, it doesn’t have to stay that way. There are a few possible solutions to help your Powerwall make less noise.

Limit Your High Energy Use

The Tesla Powerwall only makes noise when the cooling system is engaged, and frequently, this is a result of high energy use for an extended period of time. In order to prevent this, try to limit how much electricity you are using at a time, so the battery isn’t working as hard to keep up.

If you look at your Tesla management app and notice you are using high kWh, see what might be draining your solar storage. For instance, are all of the lights and televisions on in the home and the heat pump or other appliances?

If there are unnecessary power drainages, try to manage and limit this. Weather might also be a factor in the amount of energy available in your battery and how hard it is working to renew this.

It is easier for the Powerwall to replenish its electricity when the sun is blazing rather than when it is dark and raining.

If you notice that you are using high kWh and the weather is poor, you might be using more energy than the battery can efficiently restore, so it works much harder to provide the necessary electricity while simultaneously charging.

Being conscious of your overall energy use will help you to lot overwork the battery to the point that it needs to engage the cooling system.

Soundproof the Battery Room

Regardless of how efficient you are with your home energy, odds are the cooling system will be engaged at one point or another. One way to eliminate the noise it creates would be to soundproof the room that the battery is stored.

This solution is most effective and efficient for a Powerwall installed in a small room, such as a utility room in the basement, rather than a large room inside or the garage.

There are many cost-efficient soundproofing options such as acoustic foam and blankets you can hang on the walls or installing a door sweep. If the room your battery is in does not have a door but is relatively small, you could have soundproof curtains in the opening.

Be Mindful of Your Installation Room

If you haven’t purchased or installed your Tesla Powerwall yet, but you want to ensure noise isn’t an issue, make sure you choose an appropriate room for installation.

Although this product is typically very quiet, other than when the cooling system is on, if you never want to hear it, don’t install it in a common social area, such as a closet in your bedroom. However, having the Powerwall somewhere inside is highly beneficial.

If you install the Tesla Powerwall in a room that has a constantly fluctuating temperature, such as a garage or basement, it is likely the cooling system will turn on more frequently to maintain a safe temperature for the system. Therefore, it is best to install the Powerwall in a room where the overall temperature is relatively consistent.

Call Tesla Powerwall Support

If you feel that your Powerwall is making more noise than is common for the product, call Tesla Support for potential solutions from the experts.

Although it is not an altogether common issue, there is a chance that your cooling system is louder than normal because it has bubbles, or air pockets, that are blocking the flow of liquid.

If this is a concern, the Tesla team will run a script to purge the bubbles from the cooling system, which should substantially reduce any noise the system creates.

Why You Need a Tesla Powerwall

It is important to understand your equipment before discussing how to eliminate any noise complaints. The Tesla Powerwall is a lithium-ion battery and smart home energy-storage system that allows the storage and use of excess solar energy.

This system is best suited for residence or smaller businesses and is an efficient emergency option for any potential blackouts as limiting grid reliance.

The Tesla Powerwall can store up to 13.5kilowatt-hours (kWh) of usable electricity, rendering it one the highest capacity residential lithium-ion solar batteries available. And for all of its electric capacity, it is much smaller in size and weight than most competitors.

Additionally, this battery is stackable and has a sleek modern design, so it isn’t an eye-sore to your home.

The equipment comes with a Gateway management system, which allows you to manage your battery use and storage through a smart device, typically the mobile app. This allows you complete control over your Tesla Powerwall. Options include switching between different modes, such as backup-only, self-powered, and time-based control.

Final Thoughts

No one wants to trade their peaceful home for a loud power source. Despite the Tesla Powerwall being a typically silent system, the pump and fan in its cooling system can be a bit bothersome in terms of noise.

By limiting your overall use of power or installing the battery in a temperature-controlled room, you will significantly reduce the battery’s need for the cooling system.

Overall, the Tesla Powerwall is a front-runner in the industry of clean, renewable energy and would be an exceptional addition to your home. Not only does this solar battery limit your reliance on the grid, but it could also potentially reduce energy costs and provide a sense of relief when you have it for a back-up when blackouts occur.

This system is highly beneficial to residential owners and the environment, so consider switching to the Tesla Powerwall for all your energy needs.
