Running Your Rv Ac: How Many Watts Are Needed?

If you're planning an RV trip, you'll want to know how many watts you'll need to keep your air conditioning running and your camper cool. The average RV air conditioning unit needs between 1,900 and 3,500 watts to start up and between 600 and 1,700 watts to run. However, this can vary depending on the size and model of your AC unit, with some requiring as little as 500W and others as much as 2700W. To choose the right generator to power your AC, you'll need to know both the starting (surge) and running (rated) watts it requires.

Rooftop air conditioners use 500W-2700W and are hard to install

Rooftop air conditioners are the most common type of AC unit for RVs. They typically have between 5,000 and 15,000 BTUs and use a lot of power, ranging from 500W to 2700W. They are challenging to install and maintain, especially if you don't have prior knowledge of how to do so.

Rooftop AC units are also difficult to access for cleaning and maintenance, often requiring a ladder to reach them. They can be heavy and awkward to handle, and proper safety precautions must be taken to avoid injury. It is important to ensure that the unit is securely mounted to the roof to prevent damage or detachment while the vehicle is in motion.

In addition, the installation process can be complex and may require modifications to the RV's roof or electrical system. It is crucial to carefully follow the manufacturer's instructions and ensure that all connections are secure and properly sealed to prevent leaks.

Furthermore, rooftop AC units can be noisy, as they are located close to the sleeping area. This can be mitigated by choosing a unit with a lower decibel rating or installing sound-dampening measures such as insulation or vibration isolation pads.

Overall, while rooftop air conditioners are powerful and effective, they require careful consideration and planning for installation and maintenance. It may be advisable to seek professional assistance or guidance if you are unfamiliar with the process.

Portable air conditioners are low-power, low-maintenance, and quiet

Portable Air Conditioners: Low-Power, Low-Maintenance, and Quiet

Portable air conditioners are a convenient and versatile way to cool your RV, camper, or home.

RV AC wattage depends on BTU rating

The wattage required to run an RV air conditioning unit depends on its BTU rating. BTU stands for British Thermal Unit, a measure of the energy required to remove heat from the air and cool it within an hour. The higher the BTU rating, the greater the cooling capacity and the higher the wattage required to run the unit.

RV air conditioners typically have a BTU rating of either 15,000 or 13,500, although other sizes are available. A 15,000 BTU unit has a greater cooling capacity but requires more power, with average starting watts of 5,100 and average running watts of 1,600. A 13,500 BTU unit draws less power, with average starting watts of 3,800 and average running watts of 1,300.

The average RV comes with a 13,500 BTU air conditioning unit, which uses around 1,350W. This is based on an energy-efficient ratio (EER) rating of 10, with a 1,000 BTU output producing 100 watts of power. A 10,000 BTU unit typically draws between 600 and 750 watts per hour, while a 15,000 BTU unit will use 1,200 to 1,700 watts per hour.

RV air conditioning units with higher BTU ratings will have higher wattage requirements, so it is important to consider the size and power capacity of your generator when choosing an air conditioning unit for your RV.
