Can You Put a Tesla Powerwall in an RV?

Can You Install a Tesla Powerwall in an RV?

If you’re an RV enthusiast who’s interested in the Tesla Powerwall, you may be wondering if it’s possible to install one in your recreational vehicle. Unfortunately, the answer is no – at least not in its current form.

Tesla’s Powerwall is definitely not RV-friendly. Here’s why:

Designed To Be a Stationary, Home Battery

The Powerwall isn’t designed to be used as a portable battery system. It’s meant to be installed at your home or business, not in a vehicle.

It also wasn’t designed to handle the rigors of being moved around, so it could potentially break if used in an RV.

Even in their installation manual, it says the following:

… use the provided shims to ensure that Powerwall is level. The unit should be level within +/ 2 degrees side-to-side and within +/ 5 degrees front-to-back.

The Powerwall Is Too Large To Fit in an RV

The Powerwall is a large battery system that’s too big to fit inside an RV.

The Powerwall (the battery) comes with a Gateway (the brains of the whole operation).

The gateway needs about 2 feet of width and 3 feet of height. And the Powerwall itself requires 4 feet by 5 feet for each Powerwall and about 6 feet open in front of it.

It Would Be Very Expensive To Install a Powerwall in an RV

The Powerwall is expensive, and it’s not clear if it would be worth the investment to use one in an RV. There are cheaper and more efficient ways to store energy for RV use.

For example, if you only need to power small appliances and charge devices like a phone or laptop, portable power stations (Amazon) may be sufficient. And portable power stations are plug-and-play, so there’s no learning curve. Just take it out of the box and use it right away!

My wife and I have been living off-grid for awhile now and we solely live on our Ecoflow portable power stations (Amazon) and Renogy solar panels (Amazon). We have the River Mini, the River, the River Max, The River Pro with an extra battery, and an Ecoflo Delta Pro to run our entire off-grid home (my wife and I also work full-time from our home office).

However, we are very aware of how much energy we use and we downsized our fridge to a 58-quart Alpicool CF55 Portable Refrigerator/Freezer (Amazon) and got a gas-powered generator (Amazon) to run our washing machine and dryer.

And if you are looking for a small to mid-sized, DIY solar power system, there are plenty of solar power kits online. Solar power kits are a great way to learn how to build your own small to medium-sized solar system. (I’m a huge fan of Renogy’s solar kits – Amazon).

Keep in mind that if you need an uninterruptible power supply, especially if you need to run something like a CPAP (Amazon), you should think of including a gas, diesel, or propane generator (Amazon) to your setup.

Conclusion: Tesla Powerwall for RV Use

At the time of writing this post, the Powerwall is best suited for stationary homes, not RVs.

Plus, the Powerwall is about the size of a mini-fridge, so it would be difficult to fit that and the Gateway in an already cramped RV.

For RVs, there are better options available, like portable power stations (Amazon) and solar kits.

Unfortunately, the Powerwall is not designed to work with vehicles, and RVs are not equipped with the necessary wiring and hardware to support it.

However, there are some other battery options that may work for you. You really should consider a portable power station or a solar system with lithium batteries (Amazon). These batteries are designed for use in vehicles and can provide power for appliances, lights, and other electronics while you’re on the road.
