The short answer to that is yes. In fact, Tesla Powerwall could be installed in any RV. You could even include solar panels to the RV roof to charge the battery bank of the Powerwall. That enables you to park your RV anywhere you would prefer and have independent power to run all the electronics items like air conditioners, TVs, lighting, washer or dryer, satellite dishes, phone chargers, water heaters, and other appliances.

Tesla has already taken its position atop the electric power industry. They leveraged it to create the Tesla Powerwall. That technology harnesses the power of the sun and supplies power to your RV with an inverter as if you’re connected directly to a conventional power source.

Everything You Need to Know about the Tesla Powerwall for RV

Visualize picking the most remote place for a serene and majestic getaway for you and your advanced camping companions without thinking if there’s a power source at the place. Now, it is highly possible with the Tesla Powerwall.

In a traditional setup, an RV draws power from either an ampere system (generator) or a 12-volt system (battery). There are other standard uses:

  • Generator – It can power campsite items or as if you’re at home like a toaster, refrigerator, stove, TV, and others. That generator will store power and deliver it when requested. It can do so based on its capacity that is determined by design.
  • 12-volt system – It offers power to standard items through the discharge and recharge of the batteries through an external source such as an RV engine and campsite outlet.

In a new scenario, the system is replaced through a natural-power sourced Tesla Powerwall system. Thus, the time you spend in your RV could become more independent than you have ever thought. The best part here is your power will be coming from a natural source, the sun.

What is the Tesla Powerwall?

In case you didn’t know yet, Powerwall is a rechargeable lithium-ion battery recharging through solar power. It is a simple concept, right? That Powerwall could be utilized to store solar power or be utilized as backpack power in the wake of a power outage. Take note that the Tesla Powerpack is the same idea as the Powerball but designed for commercial use.

The Powerwall connects to a solar system and an inverter, which converts the current from the solar pane into electricity used by your RV. Any excess energy from this process should be stored somewhere for later use. You see, the Powerwall is the storage receptacle for that excess energy.

As you can tell, there’s some kind of technology that goes into the actual execution, but you still get the idea.

What makes the Tesla Powerwall different from others?

You see, everything is about energy. Your energy. The energy use isn’t going to change by installing the Powerwall. Instead, what will change is how the energy is sourced. Nuclear, fossil fuel, and other current energy sources are non-renewable. Other sources such as water, solar, and wind could be.

That’s what makes the Tesla Powerful different. Its battery technology is far more superior to the standard batteries to power RVs, not to mention the Powerwall could store 13.5kWh of power. How amazing is that?

Whether you wish to use solar power for convenience, the environment, and novelty, you can rest assured that the Powerwall can offer the energy you want and at the convenience your RV lifestyle offers.

Can you replace RV batteries with Tesla Powerwall?

Of course. The Tesla Powerwall can become your battery bank instead. All the electrical items and appliances you have can power on with the Powerwall as if you’re in the conventional model.

Remember that kWh is the amount of power in thousands of watts per hour that the Powerwall can generate. You may be wondering, is 13.5kWh a lot? Based on the information provided by Silicon Valley Power, appliances that use this much power are the following:

  • Washer or dryer: 10.0 kWh per load (water or dryer consumes a huge amount of power compared to other appliances)
  • Lighting – 1.0 kWh
  • Laptop computer – 0.05 kWh
  • Television – 0.071 kWh
  • Refrigerator – 0.04 kWh
  • Coffee maker – 0.4 kWh
  • Oven – 2.3 kWh
  • Air conditioner – 1.8 kWh

Total for that: 11.0 kWh (it can run 13.5 hours)

How can you charge the Tesla Powerwall?

Suppose you have a standard panel that can generate 210 watts of power per hour, and you place twelve panels on your RV. That is 2,520 watts per hour. Right?

Now, if you place your RV right in high daylight, you can produce your 13.5 kWh charge in 5.35 hours (13,500 watts / 2,520 watts).

Watching your consumption and charge is part of the entire deal as with your existing generator system. And yes, you can easily charge your Powerwall in a fraction of the day.

Just bear in mind that you can charge the Tesla Powerwall through shore power when solar power is not accessible.

How much energy can a Tesla Powerwall store?

One of the major concerns RV enthusiasts would like to learn is how much energy the Powerwall can store. You see, every Powerwall could store 13.5 kWh (or 13,500 watts). If you look at a single Powerwall of 13.5 kWh stored, that only indicates a standard RV could run under its own power at a full activity for nearly 16.5 hours.

Assume that your RV can drive at least half of the daylight hours. You can charge it for half of the daylight hours and run independently at night. That only indicates 13.5 kWh is enough for a nightly camp.

However, what about if you need or want more power? Don’t worry. One of the remarkable features of the Tesla Powerwall is that it enables you to connect it to ten Powerwalls together.

Can you externally mount a Tesla Powerwall?

Average RV generators and batteries are stored under the living area. That is less of an option for the Tesla Powerwall as it should be installed perpendicularly to the ground (as per Tesla’s instruction). Further, its dimensions are roughly four feet in height and nearly three feet wide.

The height indicates you need a high wall and its weight of 276 pounds indicates you also need a powerful attachment to the wall. Tesla mentions that the Powerwall could be installed outdoors or indoors and at relaxed ranges of -4 degrees to 122 degrees Fahrenheit. Exterior mounting is highly possible.

Just make sure that you follow the instructions from your RV for connecting add-on components to identify the ideal location.

Can the weather affect the RV’s use of solar power?

The time of clarity and the intensity of sunlight is the name of the game for solar. Keep in mind that direct sunlight on a clear day at the highest part of the day is about ideal. Every time you are collecting solar power, paying attention to the collection by intensity and time over a set time will help you understand how weather (clear, bright, rainy, and cloudy) influences the entire system.

The clearer and brighter the day, the faster it will charge. On cloudy days, you can expect a loss in power output. But it will depend on how thick the cloud cover is and how long it will last.

How difficult is it to connect the RV to a Powerwall?

Have you experienced installing electrical systems and standard RV power operations? If yes, then you need to become extra familiar with the requirements of Tesla for the Powerwall and incorporate it into your know-how.

Are you a beginner and are not intimately familiar with solar systems and panels? Then it will help if you consult a professional in this aspect.


There’s no doubt that you can power your RV along with the Tesla Powerwall, not to mention you can enjoy the great outdoors and the outdoor life with a renewable energy source, which is the sun. Now, you can comfortably listen to the tunes, watch your favorite shows and prepare tasty meals all at once while saving limited energy sources using the Tesla Powerwall of your RV.
