Can You Install a Tesla Powerwall on a Yacht?

In addition to taking the automotive industry by storm, the introduction of the Tesla Powerwall has revolutionized home energy and acts as a large battery pack that acts similar to a generator in some ways. But, could you use it outside the home, like putting a Powerwall on a Yacht?

Unfortunately, the Powerwall was not built to marine power supply standards and poses numerous safety and longevity concerns on yachts or other watercraft due to the environment below deck. However, the Powerwall remains an excellent solution for any land-based applications.

There is a time and a place for the Tesla Powerwall. Unfortunately, it is not recommended to use them on a yacht. Let’s talk about a few advantages and disadvantages of Powerwalls for maritime use.

Is a Tesla Powerwall a Good Idea on Your Yacht?

Technology is making the shift toward solar energy. Not only is it renewable, but it is also much more affordable than other types of sustainable energy. Tesla has been a leading name in alternate energy on the market, and the introduction of the Tesla Powerwall allowed consumers to harness the power outside of the automotive world.

Having reserve batteries or generators is common on yachts and other large boats. Not having to run your engine continually can save not only your motor as a whole but fuel and money. For most people, the Tesla Powerwall seemed like the perfect solution for onboard solar generators.

There are a few problems with attempting to use the Tesla Powerwall on boats:

  • The Powerwall was simply not made to be used on boats.
  • Solar power is not typically enough to power large moving vehicles, such as yachts.
  • Lithium poses safety concerns when used near water.
  • The batteries can heavily increase the weight of your yacht.

These are just a few of the main reasons that the Tesla Powerwall is not recommended for use on a yacht. With that being said, yacht owners have installed a source of solar power on their yachts and have had great results. By doing this may, in fact, void out your insurance or even cause severe damage to your boat.

In all honestly, no one can tell you what to install on your yacht and what not to. Even though a Powerwall is not ideal, there are some advantages of using solar power banks. Let’s talk about a few of the advantages and disadvantages of using a Tesla Powerwall on your yacht.

What are the Advantages of Using a Powerwall on Your Yacht?

The Tesla Powerwall is a versatile solar energy source. Although it is not recommended for use on yachts, that does not mean that you cannot install it on yours.

In addition to renewable energy, here are a few more advantages of the Tesla Powerwall.

  • Less noticeable than other solutions
  • Provides top-tier energy density storage
  • Lower overhead costs
  • Extends the life of boat batteries

One of the biggest draws of the Tesla Powerwall for yachts is the reduced costs as well as the Powerwall being an alternative form of energy. Since boats are out in the sun, it seems like using a solar power bank may be the best solution to supply power to your boat.

Many boaters love the idea of having a source of power on their yacht that is not only free but also renewable. What makes the Powerwall seem like the perfect solution is the compact appearance, a reputable brand, and powerful energy output.

However, there are also plenty of reasons you probably shouldn’t stick a Powerwall on your yacht, as we’ll see below.

Why Shouldn’t You Put a Powerwall on Your Yacht?

Now that we have covered a few reasons why you may be thinking of the Tesla Powerwall for your yacht, it is essential that we also cover some of the main reasons why it is not ideal for maritime use.

Some of the biggest reasons not to use a Powerwall on a yacht are:

  • The Powerwall is not certified for marine use. Any power storage and electric system that will be used on watercraft are engineered specifically for that purpose, and are designed to handle wet, humid, and high salinity conditions. The Powerwall was never designed with this in mind.
  • Using a Powerwall on a yacht could void your insurance. Any disaster or damage caused by using a product not rated for marine use on your yacht will likely not be covered by most insurance policies. If something did go wrong, you’d be on the hook for the full cost of repairs.
  • The Powerwall was not designed to be lightweight. Since it was designed for land use, the engineers were not attempting to make the Powerwall lightweight and portable. It would add a large amount of weight to your ship, and that can have negative consequences depending on the size of your yacht.
  • The Powerwall may cost an arm and a leg to install on your yacht. Marine power supplies often operate at voltages and amps that are different from land based systems. This could mean that the Powerwall would either be fully or partially incompatible, and could require an expensive workaround.

Another huge reason why they are not recommended is because of the severe risk of fire they can cause. Lithium is extremely flammable, even more so than fuel or oil. The use of lithium on a ship can increase the heat of your fire as well as making them very difficult to extinguish completely.

Something that is important to remember is that the Tesla Powerwall was not designed to power mobile vehicles. This means that you will run into issues with any solar panels having enough sun to charge the device properly. As with all Tesla products, they also use internet access for updates and changes, which will be an issue as well.

Is it Even Possible to Put a Tesla Powerwall on a Yacht?

Even though a Powerwall is not recommended for maritime use, that does not mean that you, as a yacht owner, cannot choose to use them on your personal watercraft. In doing so, you need to make sure that you are aware of the risks you are facing.

Due to water appearing almost anywhere on a boat, you will want to take extra precautions to ensure your Powerwall does not possibly overheat in a locked compartment or come in contact with any water.

Here are some additional things to keep in mind if you plan on installing a Powerwall on your yacht.

  • Weight distribution
  • Safe connections and wiring
  • What you plan on using all the energy for
  • How long you plan to be out to sea or offshore

Something else to consider when using a Tesla Powerwall is if your yacht has safe locations to install solar panels, which it needs to charge and store power. If you do not have many areas to install solar panels, then the output expectation will not be high.

Another option is for those who have some way of charging the Powerwall even further. If you are able to park your yacht at a personal dock, then you can also install solar panels there as a way of providing more power to the Powerwall, but you will run into issues with connections and the overall mobility of the Powerwall.

Final Thoughts

Although the Tesla Powerwall is ideal for those who are looking to supply their home with additional solar energy, that is really where the benefits end. The idea of using the Tesla Powerwall on your yacht may seem like a great solution, but using this device has drawbacks.

It is technically possible to install a Powerwall on your yacht; however, experts recommend against it.

If you still wish to install one on your yacht, make sure that you take the time to install it properly as well as understand the risks involved. Lithium can often void your boating insurance as well as permanently damage your boat and the environment.
