If you’ve ever wondered if you can use a Tesla Powerwall in your RV, then you are in the right place. Imagine being able to have seemingly unlimited “off-grid” power in your RV. So, is it possible to install a Tesla Powerwall in an RV?
Yes, a Tesla Powerwall can absolutely be installed in an RV, further you can even add solar panels to your RV roof to charge the Powerwall’s battery bank. This allows you to park your RV anywhere you’d like and have independent power to run all of your electronic items such as:
- Air Conditioners
- Appliances (refrigerators, microwaves, ovens)
- Water heaters
- Phone chargers and power banks
- Satellite dishes
Tesla has taken its position atop the electric power industry and leveraged it to produce the Tesla Powerwall. This technology harnesses the power of the sun and, with an inverter, supplies power to your RV as if you were connected directly to a conventional power source. Read on to see how simple it is to get started.
The Tesla Powerwall for RV Power Freedom
Imagine choosing the most remote spot for a beautiful, peaceful getaway for you and your high-tech camping companions without wondering if there is a power source at that site. It is possible with the ultimate Tesla Firewall.
In a conventional setup (non-Powerwall), an RV draws power from either the 12-volt system (the battery) or an Ampere system (generator). There are some typical uses for each, as outlined in this video:
|12-volt system (battery)||Ampere system (generator)|
|Water pump||Air conditioning (not auto air conditioning)|
|Water heater||Small kitchen appliances|
|Refrigerator||Washer/Dryer if installed|
- The 12-volt system provides power to typical items via the discharge and recharge of the batteries via an external source like a campsite outlet or the RV engine.
- The generator: powers “campsite” items or as if you were at home such as the TV, stove, refrigerator, toaster, etc. This generator will store power and also provide it when requested and can do so based on its capacity, which is determined by design.
In the exciting new scenario, the system is replaced with a natural-power sourced Tesla Powerwall system. The time you spend in the RV can be more independent than you have ever imagined, and your power will be from a natural source – the sun.
How is the Tesla Powerwall different?
It is all about the energy! Your energy use is not going to change by installing the Powerwall. What will definitely change is how your energy is sourced. Fossil fuel, nuclear, and other current energy sources are practically non-renewable, while sources such as wind, water, and solar can be.
This is how the Tesla Powerwall is different: It’s battery technology is far superior than traditional batteries used to power RV’s, and the Powerwall can store a whopping 13.5kWh of power!
Whether your incentive to use solar power is for the environment, convenience, or novelty, the Powerwall can provide the energy you need, and at the greater independence, the RV lifestyle provides.
Can Tesla Powerwall Replace My RV Batteries?
Yes. The Powerwall becomes your battery bank. All those appliances and electrical items can power on with the Powerwall as if you were in the conventional mode.
A kWh is the amount of power, in thousands of watts (kW) per hour, that the Powerwall can produce. So, is 13.5 kWh a lot? According to Silicon Valley Power, appliances use this much power:
|Washer/Dryer||10.0 per load*|
|Total load||11.0 kWh (can run 13.5)|
*Washer/Dryer uses a lot of power compared to other appliances.
How Much Energy Can Powerwall Store?
One of the biggest questions an RV enthusiast may want to know is how much energy the Tesla Powerwall can store.
Each Powerwall can store 13.5 kWh (or 13,500 watts). Looking at a single Powerwall of 13.5 kWh stored, that means a typical RV can run under its own power (at “full activity” described in the table) for almost 16.5 hours!
Consider that an RV will drive half of the daylight hours, charge for half of daylight hours and operate independently at night. That means 13.5 kWh is plenty sufficient for a nightly camp.
What If I Need or Want More Power?
One of the outstanding capabilities of the Powerwall is you can connect up to 10 Powerwalls together (135kWh or 135,000 watts maximum).
How do I charge the Tesla Powerwall?
There is some easy math for this question. Say you have a typical solar panel that can produce 210 watts of power per hour, and you put 12 panels on your RV, as did “we call it camping” in their real-world demonstration. That is 2,520 watts per hour.
If you position your RV right in “high daylight,” as I call it, you can generate your 13.5 kWh charge in 5.35 hours (13,500 watts / 2,520 watts).
As with your current generator system, watching your consumption and charge is part of the deal. And yes, you can charge your Powerwall in a fraction of the day.
Important: Always keep in mind you can charge your Tesla Powerwall via shore power if solar power is not available.
Can A Powerwall Be Mounted Externally?
Typical RV batteries and generators are stored beneath the living area. This is less of an option for the Powerwall because it must be installed perpendicularly to the ground according to Tesla and the dimensions of the Powerwall are around 4 feet in height and almost three feet wide.
The height means you need a high wall and its weight of 276 lbs. means you need a strong attachment to the wall (specs). Since Tesla states that the Powerwall can be installed indoors or outdoors and at comfortable ranges of -4 degrees to 122 degrees Fahrenheit, exterior mounting is possible. Follow your RV instructions for attaching add-on components to determine the best location.
How Does Weather Impact an RV’s Use of Solar?
The intensity of sunlight and time of clarity is the name of the game for solar power. Direct sunlight on a clear day at the highest part of the day is just about perfect.
When collecting solar power, monitoring the collection by time and intensity over a period will help to understand how weather (cloudy, rainy, bright and clear) affects the system.
The brighter and clearer the day, the quicker the charge. On cloudy days, expect a loss in power output, depending on how thick the cloud cover is and how long it lasts.
Is It Difficult to Connect an RV To A Tesla Powerwall?
If you have experience installing electrical systems and typical RV power operations, you will only need to become familiar with Tesla’s requirements for the Powerwall and integrate it into your own knowledge. If you are a novice or are not intimately familiar with solar panels and systems, it is best to consult a professional in this area.
RV Life Only Gets Better with The Tesla Powerwall
Yes, you can power your RV with the Tesla Powerwall, and you can enjoy the outdoor life with a renewable energy source – the sun. Listen to tunes, watch the game and prepare a delicious meal all at once while conserving limited energy sources using your RV’s Tesla Powerwall.
