Will A 2200 Watt Generator Run An Rv Air Conditioner

Will a 2200 Watt Generator Run an RV Air Conditioner?

One of the most common questions asked by RV owners is whether or not a 2200 watt generator can run their RV air conditioner. The answer to this question can vary depending on various factors such as the size and efficiency of the air conditioner, the altitude at which you are operating, and the additional electrical loads that are present in your RV.

The Power Requirements of an RV Air Conditioner

Before determining whether a 2200 watt generator can power your RV air conditioner, it’s important to understand the power requirements of the air conditioner unit itself. Most RV air conditioners typically require a starting wattage of 3000 to 3500 watts and then settle into a running wattage of around 1500 to 2000 watts. However, it’s worth noting that some newer and more efficient models may require less power.

The Limitation of a 2200 Watt Generator

While a 2200 watt generator may seem like it has enough power to run an RV air conditioner, it’s important to consider its limitation. A generator’s rated wattage refers to its running power, not the surge power required to start certain appliances or equipment. This means that a 2200 watt generator may struggle to start an air conditioner that requires more than its initial surge wattage.

Additionally, if you are at a high altitude, the air density decreases, which affects the power output of a generator. In such cases, a 2200 watt generator may produce even less power than its rated wattage, reducing its ability to reliably run an air conditioner.

Factors To Consider

Before attempting to run your RV air conditioner with a 2200 watt generator, it’s important to assess the following factors:

  1. Air Conditioner Size and Efficiency: Larger or less efficient air conditioners may require more power to start and run, exceeding the capabilities of a 2200 watt generator.
  2. Additional Electrical Loads: Take into account other appliances or electrical devices running simultaneously in your RV, as they will add to the total power consumption.
  3. Altitude: If you plan to operate your RV at high altitudes, you may need to consider a larger generator to compensate for the decrease in power output.

Alternative Solutions

If your 2200 watt generator is unable to run your RV air conditioner, you still have a few options:

  1. Upgrade to a Larger Generator: Consider investing in a generator with a higher wattage rating to ensure reliable operation of your air conditioner.
  2. Reduce Power Consumption: Optimize energy usage in your RV by minimizing the use of other high-powered appliances while the air conditioner is running. Use energy-efficient light bulbs, unplug unused devices, and adjust your thermostat to save power.
  3. Utilize an Air Conditioner Soft Start Kit: Installing a soft start kit on your air conditioner can reduce the power surge required at startup, allowing it to run more efficiently on a smaller generator.
