The Best Places to Install A Tesla Powerwall

The Tesla Powerwall is one of the most innovative advancements seen in the field of technology. With the ability to power your entire house with renewable energy, the Tesla Powerwall is worth the investment. But where is the best place to install it?

The Tesla Powerwall can be installed in a range of areas, but some factors have to be considered. While it is a highly durable piece of technology, it is not indestructible. When necessary precautions are taken, your Tesla Powerwall will be able to function at maximum efficiency.

Continue reading to learn about the best places to install a Tesla Powerwall. There is a range of options for the installation location, with several aspects to consider for different situations. Based on your opinion, you might find that some circumstances prove more reliable than others.

Regional Location

Of course, the first thing to think about is where you live; this will be the initial determining factor of how easy of a process it will be to order your Tesla Powerwall and have it professionally installed.

Tesla licenses installation abilities to companies worldwide, so if there is a company with licensing privileges near you, you are in luck. If not, Tesla will still happily accommodate their services to your needs, but the process might take a bit longer.

So, geographically, the best place to install a Tesla Powerwall is in an area where a company is close enough to get to you and complete the installation process. If there is no company with installation privileges nearby, not all hope is lost, but it certainly makes the process easier.

Outside Vs. Inside

Once you have contacted someone to install your Tesla Powerwall, you can begin thinking about the specifics of where in your house it is going to go. The first order of business: is it going inside or outside?

A Tesla Powerwall is not unnecessarily large – about 4 ft. x 2 ½ ft. If you have space in your home for it, it has a sleek enough design to fit in without standing out. However, being a large piece of technology to power your whole house, you might wish to have it installed outside of your home. As long as you have space for it and follow the steps in the rest of this article, whether you install it inside or outside is predominantly up to you.

The leading cause for concern when installing your Tesla Powerwall outside is if you live in a region of extreme climate. This might affect the installation area of your Powerwall in a few ways:

  • Tesla Powerwall is operative in the range of -4 to 122 degrees Fahrenheit.
  • However, it works best between 32 and 86 degrees, so if this would be a problem for you if installed outdoors, you should consider installing it inside.
  • In extreme temperatures, the Tesla Powerwall will often adjust to using power at a lower rate for increased efficiency.
  • If you want to avoid this happening, avoid installing it outside.

Below are other factors that might influence where exactly you install your Tesla Powerwall. While it still is efficient in extreme conditions, you do not want to test your Powerwall’s limits too severely.


While the Tesla Powerwall is fully capable of functioning off of solar power, too much exposure to direct sunlight is not an ideal situation.

If you decide to install your Powerwall outside, it should be in an area with at least some sort of cover from the sky. If the Powerwall is continuously exposed to the Sun, it will not work at the highest quality possible.

This is not typically a common problem because if your Powerwall is installed outside of your house on an outer wall, it is likely that the outer wall’s shade will protect it for at least some of the day.

Of course, the indoor installation will not pose a risk for this circumstance.


The Tesla Powerwall is manufactured with an outer layer that adds water resistance, so precipitation is not a problem. Any rain, sleet, snow, etc. is not going to damage your Tesla Powerwall.

On the other hand, you do not want to install your Tesla Powerwall in an area that often floods due to weather conditions, especially if your Powerwall touches the ground.

Saturated terrain can be highly detrimental to the capability of your Tesla Powerwall, so avoid installing in direct contact with ground that floods regularly. In any case, your Powerwall can be installed higher up on your wall so that it is not in contact with the ground.


Similarly, you do not want natural outdoor items to lessen your Tesla Powerwall’s ability to function. The wear and tear of nature can take a toll on anything.

For instance, be careful installing your Powerwall in an area where a tree might stand overhead. When all of its leaves fall, they can crowd the Powerwall and block its openings from proper ventilation.

This can also happen if your grass is too long, excess dirt surrounds your Powerwall, or any other type of debris gets in the way. So, if you decide to install outside, make sure that your Tesla Powerwall is installed in a clean area.

Underground Installation

You might also have the option of installing your Tesla Powerwall underground. While the process includes additions that will aid ventilation and other functions, there are still some things to consider.

With underground installation, your Powerwall will be unlikely to experience problems from the weather, so that is a definite plus.

On the other hand, you should consider the additional cost of having to dig underground and invest in critical structural and functional support systems to ensure that your Powerwall works correctly. With this in mind, you might not want to spend the extra money.

There are going to be pros and cons to every scenario. With underground installation, you have the same situation:

– Less risk of weather damage

– Chance of problems from debris blocking ventilation decreases

– You do not have to worry about seeing it (although many think the Powerwall is a sight for sore eyes)
– Extra cost for digging and installing

– If problems do occur, even more money to dig it up for an examination

– Location might not be ideal for connection to electrical or solar panels

Safety Precautions

Regardless of if you are installing your Tesla Powerwall inside or outside, there are still some general safety precautions to keep in mind. As with any large piece of technology – especially one with the energy sufficient to power your house – you will want to make sure it is in a safe place.


  • Beware of objects around your Powerwall that could block ventilation
  • Consider putting it in an area without much foot traffic throughout the day
  • Keep it in a close enough location to reach your main electrical panel


  • Keep it in a clean area with little risk of outdoor interruption
  • Do not put it in a place where it will be crowded by an electric box, air conditioning unit, etc.
  • Take note of the climate in your region to see if outdoor installation is truly the best option


  • Before digging, locate water pipes or underground power lines
  • Gather necessary materials for keeping the Powerwall safe and secure underground
  • Install underground close enough to your home

Distance to Main Electrical Panel

As briefly discussed above, you will want to make sure that where you install your Tesla Powerwall is close enough to connect to the main electrical panel.

If you are using solar power only, this is not going to be a problem, but if you decide to connect your Powerwall to the public grid, it will need to be able to connect securely.

During the installation process, you will have to have access to your home’s electric motherboard so that you can hook the Powerwall up to it. If you cannot, your Powerwall will not work.

Therefore, wherever you install your Powerwall, make sure that it is not too far from the electric panel. You will not want to spend extra money on additional wiring or any other materials to fix this problem.

To simplify things and avoid a distance problem, contact the installer of your electric panel, and get information regarding its location in your home and what you will need to do to connect your Powerwall to it.

Network Connection

This aspect of the installation process is not entirely required, but having a special network connection will allow your Tesla Powerwall to function best.

If you wire your Powerwall to your main electrical panel, you should be able to also use a wired network just fine. If not, you can connect to the network through your Wi-Fi.

The reason you might want to connect to your network is for overseeing the inner workings of your Tesla Powerwall. If it is connected to the internet, you can monitor its energy output from your smartphone.

If you choose to do this, you will need to make sure your Powerwall is installed close enough to your router to have a stable connection. If you struggle to have reliable service in your home, you might want to consider installing your Powerwall indoors and near your network connection. If you have a secure enough connection that it could still work outside, that is also a viable option.

Benefits of installing your Powerwall close enough to your network connection include:

  • Monitoring and adjusting the energy of your Tesla Powerwall
  • Being able to recognize internal problems and either fix them or get professionals to help
  • Make your overall experience with your Tesla Powerwall all the more straightforward and worthwhile

While it is not absolutely necessary, connecting to your network will give you many more benefits with your Tesla Powerwall. However, if you choose to do so, there are more options to think about. Read below for more information on the Tesla Powerwall and your network connection.

Wired Vs. Wireless

If you have a wired connection, chances are that it will be more secure than a wireless network. However, there can be advantages and disadvantages for both.

Whichever type of connection you have is likely to work out fine, so do not worry about changing your whole network set up just for your Tesla Powerwall. The only significant difference is that you will probably have less say when your Powerwall is installed if you have a wired connection. As mentioned earlier, it will have to be close enough to be wired to the network.

– Likely a more secure connection

– Fewer options for installation location

– Internal wiring problems can be a burden to deal with
– Sufficient connection, but not always as reliable as wiring

– You will not have to worry about wiring problems; if something goes wrong with the connection, it is all through a wireless network

– More room to expand the distance of your Powerwall from the network

These advantages and disadvantages are not always the case when comparing wired vs. wireless connection, but they are ordinary circumstances among each. However, as a network connection is not a major deciding factor for installing a Tesla Powerwall, you should not spend too much time on the choice.

Also, Tesla is one of the -if not the number one- most technologically advanced companies in the world. With their products and installation processes, things like wiring problems might be completely irrelevant.


The idea of controlling the energy output of your Powerwall is a considerable advantage in the technology industry. This is especially beneficial if you do not use your Tesla Powerwall as the primary energy source for your home.

In the circumstance of using it as a backup generator, you have the power to shut your Powerwall completely off. In the event of a power outage, you can fire it up in the palm of your hand.

Even if you use it as the main energy supply, it can still be beneficial. If you recognize that you do not need as much energy as your Powerwall battery is supplying, you can crank the output down a bit to conserve more energy.

Structural Support

This one might be a given, but the best place to install a Tesla Powerwall must be sufficient to hold its weight. The Powerwall and all of its components weigh over 250 lbs., so you are going to need some structural support.

If you install your Powerwall outside, you will probably not have any trouble with this. However, indoor installation might cause problems. You are not going to be able to install your Powerwall on a simple piece of drywall. Without studs or another type of strong wall, your Powerwall might just rip your wall to shreds.

Before installing indoors, find out the strong parts of your wall that can support your Tesla Powerwall, whether it be drywall with thick studs behind it or a cement basement wall. The last problem you will want to face with your Powerwall is installing it on a weak frame.

Mounting Multiple Powerwalls

One Tesla Powerwall will take care of your needs, but having additional ones can boost your power to the highest amount possible. In this instance, however, you might want to consider where to install all of your Powerwalls.

With the installation of multiple Powerwalls, you are obviously going to need more space. Indoor installation can pose problems in this event because you might not want your home’s entire wall to be covered with Tesla Powerwalls.

Outdoor installation might be your best choice because multiple Powerwalls can be stacked or placed side-by-side easily. Still, you will need to make sure all of the previously mentioned things – adequate ventilation, strong structural support, distance to the electrical panel, etc. – are considered.

Popular Choice

Most people with Tesla Powerwalls install their Powerwalls outside. Because Tesla manufactures their products with the most innovative advancements available, outdoor installation works well.

Just because most people do it, however, does not mean it is without question the best option. Your personal preferences will have a significant influence on the best place for you to install your Powerwall.

However, if you have qualms about installing your Powerwall outside, knowing that most people do this might give you a bit of peace of mind.

It is also worth noting the use of your Powerwall to connect your Tesla vehicle to its battery charger. Many people install their Powerwalls outside of the garage for efficiency when charging a Tesla car.
