In this article, allows see exactly how much watts does one rv wait conditioner draw and also some other considerations for making use of AC in her motorhome or take trip trailer or any kind of other camper.


What is the mean power intake by a rv wait conditioner

The power consumption of a wait conditioner in rv will be different depending upon the BTU rating the the AC. BTU is nothing however an acronym because that British thermal unit, which basically measures the heat or thermal energy.

An wait conditioner normally will have actually 2 watt ratings. A watts required to execute the begin up and also the watts that space consumed by it during running. A start-up watts forced are greater as contrasted to the running watts requirement. Thus, the generator you are using to operation the AC should have watts much more than the start watts forced by the AC.


Now, comes to the key point, how countless watts are essential by the air conditioner in rv? together i said, it depends on BTU, allows see average watts essential by different BTU rated air conditioners to store running and also the begin up watts. This number are average values and not accurate because it depends on lots of components like the age of AC, brand of ac etc. A more efficient generator will certainly use much less wattage but on an average the numbers will be approximately the watts stated below.

 On an mean a 15,000 BTU wait conditioner needs around 3200 to 3500 watts for begin up On an average a 13,500 BTU air conditioner needs roughly 2700 come 2900 watt for start up On an median a 10,000 BTU air conditioner needs roughly 1900 to 2050 watts for begin up On an average a 7,000 BTU waiting conditioner needs roughly 1600 come 1800 watts for begin up On an average a 5,000 BTU air conditioner needs roughly 1100 come 1300 watt for begin up

Similarly, the running wattage to compare for various RV air conditioners for different BTU is together below. As you can see, the watt are an ext than fifty percent of that forced for beginning up.


 On an mean a 15,000 BTU wait conditioner needs about 1200 come 1700 watts for running On an average a 13,500 BTU wait conditioner needs around 1000 come 1300 watt for running On an average a 10,000 BTU air conditioner needs around 600 to 750 watt for running On an average a 7,000 BTU wait conditioner needs roughly 500 to 650 watt for running On an typical a 5,000 BTU wait conditioner needs roughly 300 to 450 watt for runningAC BTUStarting WattsRunning Watts
50001100 -1300 W300 – 450 W
70001600 – 1800 W500 – 650 W
10,0001900 – 2050 W600 – 750 W
13,5002700 -2900 W1000 -1300 W
