Understanding RV Power Requirements

To fully appreciate the great outdoors while maintaining a comfortable indoor environment, a reliable power source is paramount. This is where your RV generator steps in. It powers everything from your air conditioning units to your kitchen appliances, ensuring your RV truly feels like a home on wheels.

When it comes to RVs equipped with two AC units, the need for a substantial and consistent power supply is even more critical. Air conditioning is one of the highest power-consuming appliances in an RV, and having two units can significantly increase your power needs.

Selecting the Perfect Generator for Your RV with 2 AC Units

First, let’s answer the question that brought you here: What size generator do you need for an RV with two AC units? The answer lies in understanding your air conditioners’ power requirements. The majority of RVs come standard with 13,500 BTU air conditioners.

A single AC of this 13,500 BTU value requires a 3,000-watt generator. This is because the starting wattage for this AC is around 2,800 watts, and the running wattage is approximately 1,800 watts. So, when you install two of these AC units, your required starting wattage is around 5,600 watts, and your running wattage is approximately 3,800 watts. Therefore, a 6,000-watt generator should be sufficient for powering two RV air conditioners, given that their BTU value is 13,500.

You might be thinking, “That’s fantastic! I’ve got my answer!” But hold on. We’re just getting started. While the numbers above give you a general idea, there’s more to understand about selecting the ideal generator for your RV, and we’re here to help you navigate through it.

Consider Other Things While Selecting the Generator

The wattage requirement isn’t the only factor to consider when choosing a generator. You also need to think about its fuel efficiency, noise level, portability, and how well it can handle other electrical devices in your RV. After all, your RV is more than just an air-conditioned space; it’s your home on the road.

Fuel Efficiency is a critical factor because it directly impacts how long your generator can keep your RV powered. A more fuel-efficient generator will run longer on the same amount of fuel, saving you money and trips to the gas station.

Noise Level is another important consideration. Nothing ruins the serene ambiance of a natural setting like a loud generator. Look for generators that operate quietly without sacrificing performance. There are models available that balance power output and noise level beautifully, ensuring your peace and comfort.

Portability is essential, especially if you often move your generator around. You don’t want a generator that’s a struggle to transport. Look for models that are compact, lightweight, and come with features like wheels and handles for easy movement.

Finally, don’t forget that your RV has more electrical devices besides the air conditioners. From refrigerators and microwaves to TVs and laptops, all these devices add to your total power requirement. So, while a 6,000-watt generator might suffice for your dual AC units, you might need a slightly more powerful one if you plan to use several appliances simultaneously.

Wrap Up

In conclusion, finding the perfect generator for your RV with two AC units isn’t a complicated task. With a bit of knowledge about your power needs, and with the considerations we’ve outlined, you’re already well on your way to making an informed decision. Remember, an RV with two 13,500 BTU air conditioning units will require a generator with at least 6,000 watts of power. This will ensure that your AC units run smoothly, keeping your RV cool and comfortable.

However, this is not a strict rule, as your total power needs might be higher depending on the other appliances and electrical devices in your RV. Therefore, always calculate your total power requirements and choose a generator that can meet these needs efficiently and quietly.

Remember, a comfortable RV adventure is not just about having the right size generator but also about making the most of the journey. So choose wisely, keep cool, and enjoy the ride!

Frequently-Asked Related Questions (FAQs)

Q1: Can a generator run both AC units simultaneously?

Yes, a 6,000-watt generator should be able to power two 13,500 BTU AC units simultaneously. However, it’s advisable to stagger the starting times of the units to avoid overloading the generator.

Q2: Can I run other appliances while the AC units are running?

It depends on the total power requirement of the appliances. If the combined wattage of all appliances, including the AC units, doesn’t exceed the generator’s capacity, you can run them simultaneously.

Q3: What if my AC units are larger than 13,500 BTUs?

If your AC units are larger than 13,500 BTUs, you would need a more powerful generator. For instance, a 15,000 BTU AC unit requires about 3300 starting watts and 2,000 running watts, so a 4,000 to 5,000-watt generator would be necessary. However, it’s likely that you wouldn’t need a second AC unit in this case.

Q4: What if my AC units are smaller than 13,500 BTUs?

If your AC units are smaller, say 11,000 BTUs, then each unit would require at least 1600 starting watts and 1010 running watts. In this case, a 2000-watt generator would be sufficient for each AC unit. You may, however, need two AC units to keep your RV cool enough​

Q5: Can I use a generator larger than 6,000 watts for two 13,500 BTU AC units?

Yes, you can use a larger generator, but it may not be energy-efficient. Oversized generators could lead to unnecessary fuel consumption and increased costs.
