Motorhome air conditioners are a great way to keep cool while on the road, but they can be power-hungry. Solar panels provide a renewable and environmentally friendly way to generate energy for your devices, so it’s natural to wonder if you could also use them to run a motorhome air conditioner.
This article will examine how motorhome solar panels work and whether you can use them to run an air conditioner. We’ll also explore what size solar system you need to run an air conditioner and whether it’s worth using solar for your motorhome air conditioner.
Can You Run a Motorhome Air Conditioner on Solar Power?
The short answer is yes; you can run a motorhome air conditioner using just solar power. Solar panels convert sunlight into electrical energy, which you can use to run devices like air conditioners. They’ll reduce the cost to keep your motorhome up and running (and comfortable) and have a low maintenance cost, so they can be a great way to keep cool on the road without breaking the bank.
However, there are a few things to keep in mind if you’re planning on using solar to run your motorhome air conditioner.
You’ll need a solar system that is large enough to generate enough energy to run your air conditioner. The solar system size, in this case, isn’t about the dimensions but the battery capacity.
The capacity you’ll need will depend on several factors, including the size of your motorhome air conditioner and the amount of sunlight you get each day. If your motorhome is large and you want the cool air blasting 24/7, the solar system you’ll need will require a higher power rating. The dimensions go hand in hand, meaning the unit might take up more of your (already limited) space.
It’s also important to note that solar panels generate more energy when the sun is out. You’ll only be able to use your air conditioner if your solar system has enough access to sunlight during the day. If you are in an area with cloudy, rainy weather, the power you’ll get from your solar panels may not be sufficient.
How Motorhome Solar Panels Power a Motorhome Air Conditioner
Using solar panels to run your motorhome air conditioner might seem a more complex process than you initially thought, especially if you have never installed a solar unit. Let’s review how it works when using EcoFlo Solar Generators so you can decide whether it’s the right solution for you.
Solar panels feature individual photovoltaic cells that convert sunlight into electrical energy. This process generates electrical energy that the unit stores in batteries. You can use this energy to run devices like air conditioners.
The stored energy in the battery bank is consumed by your motorhome air conditioner when it’s turned on to keep your vehicle’s interior cool. With a 3600W output, EcoFlow’s Power Kit can supply enough energy needed to keep a motorhome A/C system up and running.
What makes our Power Kits different from most motorhome solar panel systems is that there are four ways to generate energy, including three alternative methods to solar. Even if you don’t have sufficient access to the direct sunlight you need for solar-only energy, you can still get the power you need through a hookup for your vehicle’s alternator, an input for a backup generator, or a shore input to plug directly into your campsite’s electricity hookup.
Standard solar panel systems for motorhomes can take up tons of your valuable space. Our Power Kit is a space-saving solution. It’s much smaller than traditional models, using components like thinner wires, stackable batteries, and conveniently concealed equipment. The result is a robust portable power solution that keeps the wiring and other components out of sight and out of mind.
Components Needed to Run a Motorhome Air Conditioner with Solar
Running your motorhome’s air conditioner with solar requires more than just solar panels. You need an entire solar power system, which requires several different components.
Solar Array
The solar array refers to the solar panels themselves. The number of panels in your array will depend on the size of your motorhome and the amount of energy you need to generate.
For example, suppose you want to run your air conditioner in your motorhome for around 8 hrs a day. A good general guideline is to look for an array and system that can generate about 1800 watts of solar plus about 700-800 amp hours (AH) from your battery bank.
Battery Bank
The battery bank is usually a lithium-ion battery bank that can hold and store the energy that your solar array generates. The larger your battery bank is, the more power you’ll be able to store and consume between charging times.
Our Power Kit’s battery banks are modular and stackable, so you can outfit your system with whatever batteries you need.
Inverter
Your battery bank will produce DC (direct current) energy. However, motorhomes run on AC (alternating current) power. An inverter will turn that DC energy into AC energy your motorhome can use.
EcoFlow’s Power Kit battery bank uses 48V power. It is safer and produces less heat than 12V, reducing energy loss. The battery bank transforms it into AC power, so you can charge appliances that require AC, including your air conditioner.
Power Hub
The hub makes EcoFlow’s Power Kit different from other models on the market. It’s a small, single unit that holds all your inputs and outputs in one place.
The EcoFlow hub combines a battery charger, two solar charge controllers, an inverter charger, and a converter all in one compact device.
Power Kit Console
The control centre for your setup is the Power Kit Console, which features a user-friendly touchscreen. You can monitor your usage, control your inputs and outputs and manage everything in one place via a simple ethernet cord.
What Size Solar System You Need to Run a Motorhome Air Conditioner
To figure out what size of system you’ll need to run your motorhome air conditioner, you’ll need to know the power requirements of your air conditioner. Most motorhome air conditioners will have a rating of watts (W) or amps (A).
You can find the power rating of your air conditioner in the owner’s manual or on the manufacturer’s website. Once you have this number, you’ll need to multiply it by 1.25 to account for any inefficiencies in the system. This calculation will give you the total energy that your air conditioner will use while running.
For example, say your motorhome air conditioner has a power rating of 1000W. You’ll need a system that can generate at least 1,250W to keep it running:
1000W power rating x 1.25 efficiency margin = 1250W continuous output
Is It Worth Using Solar for Your motorhome Air Conditioner?
Now that we’ve covered how to use solar power to run a motorhome air conditioner, you might wonder if it’s worth using solar for your motorhome air conditioner.
There are a few advantages of using solar to run your motorhome air conditioner that you should consider when making this decision:
- Renewable resource— more environmentally friendly than a fossil-fuel generator
- More convenient and requires less maintenance than fossil-fuel generators
- Quieter than fossil-fuel generators
- More cost-effective in the long run
On the other hand, there are several reasons why using a traditional solar system to run your motorhome air conditioner might be challenging:
- Solar power isn’t always readily available; power generation can be weaker on cloudy or stormy days
- Some solar systems can be expensive and bulky
- Not all motorhomes are suitable to be outfitted for solar
