When it comes to powering an RV air conditioner, the question of whether a 2200-watt generator is sufficient is a common one among RV enthusiasts. The answer, however, is not as straightforward as one might hope. It depends on several factors, including the specific model of the air conditioner, the starting and running watts required, and the overall power consumption of your RV.
Understanding Power Requirements
First, let’s break down the power requirements. Most RV air conditioners require a significant amount of power to start up, often much more than they need to run continuously. This initial surge is known as the “starting watts” or “surge watts.” Once the air conditioner is running, it settles into a lower power consumption mode, known as “running watts.”
A typical RV air conditioner might require around 1500-2000 watts to start and then settle down to around 600-1200 watts to run. This means that a 2200-watt generator could theoretically handle the starting watts of some RV air conditioners, but it would be cutting it close. If your air conditioner requires more than 2200 watts to start, the generator may not be able to handle the load, leading to potential issues like tripping the circuit breaker or damaging the generator.
The Role of Inverter Generators
Inverter generators, which are often more efficient and quieter than traditional generators, can sometimes handle higher starting watts than their rated output. This is because they can temporarily boost their power output to accommodate the initial surge. However, this capability varies by model, so it’s essential to check the specifications of your specific generator.
Other Power Considerations
Even if your 2200-watt generator can handle the air conditioner, you need to consider other power demands in your RV. Lights, appliances, and electronics all draw power, and if you’re running multiple devices simultaneously, you could easily exceed the generator’s capacity. It’s crucial to calculate the total power consumption of all the devices you plan to run at the same time to ensure your generator can handle the load.
The Importance of a Soft Start Kit
One way to reduce the starting watts required by your RV air conditioner is to install a soft start kit. This device reduces the initial surge of power needed to start the air conditioner, making it easier for your generator to handle the load. A soft start kit can be a worthwhile investment if you frequently rely on a generator to power your RV air conditioner.
Real-World Scenarios
In real-world scenarios, many RVers have successfully used a 2200-watt generator to power their air conditioner, especially if they’ve taken steps to reduce the starting watts. However, others have found that their air conditioner requires more power than their generator can provide, leading to frustration and the need for a more powerful generator.
Conclusion
In conclusion, whether a 2200-watt generator can run an RV air conditioner depends on the specific power requirements of your air conditioner and the overall power consumption of your RV. While it’s possible in some cases, it’s essential to carefully consider the starting watts, running watts, and other power demands before making a decision. Installing a soft start kit and using an inverter generator can increase your chances of success, but ultimately, the best course of action is to consult the specifications of your air conditioner and generator to ensure compatibility.
Related Q&A
Q: Can a 2200-watt generator run a 13,500 BTU RV air conditioner?
A: It depends on the starting and running watts of the air conditioner. Some 13,500 BTU units may require more than 2200 watts to start, making a 2200-watt generator insufficient. However, with a soft start kit, it might be possible.
Q: What is the difference between starting watts and running watts?
A: Starting watts (or surge watts) are the power required to start an appliance, which is often much higher than the running watts needed to keep it operating. Running watts are the continuous power required to keep the appliance running.
Q: How can I reduce the starting watts of my RV air conditioner?
A: Installing a soft start kit is one of the most effective ways to reduce the starting watts of your RV air conditioner. This device reduces the initial power surge, making it easier for your generator to handle the load.
Q: Can I run other appliances while using a 2200-watt generator to power my RV air conditioner?
A: It depends on the total power consumption of all the appliances you want to run simultaneously. If the combined wattage exceeds the generator’s capacity, you may need to prioritize which appliances to use or consider a more powerful generator.
Q: Are inverter generators better for running RV air conditioners?
A: Inverter generators are often more efficient and can sometimes handle higher starting watts than their rated output. They are also quieter and more fuel-efficient, making them a popular choice for RVers. However, it’s essential to check the specific capabilities of your generator model.
