An air conditioner usually will have 2 watt ratings. A watts forced to carry out the start up and the watt that room consumed by it throughout running. A start-up watts compelled are greater as compared to the running watt requirement. Thus, the generator you space using to operation the AC should have actually watts much more than the begin watts compelled by the AC.


Now, coming to the main point, how plenty of watts are required by the air conditioner in rv? as i said, it counts on BTU, allows see average watts needed by different BTU rated air conditioners to save running and likewise the begin up watts. These number are typical values and also not accurate because it counts on lots of components like the age of AC, brand the ac etc. A much more efficient generator will certainly use much less wattage however on an typical the numbers will certainly be approximately the watts mentioned below.

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