generator/inverter

[Dogkinkead]

I have a 13QBB with the air conditioner mounted through the side, looks like a conventional AC window unit.  Question is what size generator or inverter would I need to run the AC while boondocking?

For an RV air conditioner, the starting wattage is typically around 3,000 watts. However, you'll want to purchase an inverter between 3,500 and 4,000 watts so you don't max out your inverter. It also may be a good idea to buy a soft starter.

You will need to determine the starting watts required by your AC unit. This information can also be found on the label or in the user manual. Most air conditioners require 2 to 3 times their rated power consumption to start up, so in the example above, the starting watts could be between 3,000 and 4,500 watts.

Once you have these numbers, you can choose a generator or inverter that can provide enough power to run your air conditioner. A generator with a rated output of at least 3,000 to 4,500 watts and a starting output of at least 4,000 to 6,000 watts should be sufficient. Alternatively, you could use an inverter that can handle the starting watts of your AC unit, such as a 3,000-watt inverter e.g.Firman W03083. Keep in mind that the inverter must be connected to a battery or other power source, such as a solar panel, to work properly.

What is the size of your air conditioner? I recommend you use Harbor Freight in tool predator 3500 W inverter generator.

Actually all depends on the size of your air conditioner and how often you plan to use the generator to run it. If it's a small 8000 BTU you might get away with a single 2000 watt generator but you will be taxing it.. For example the Honda EU 2200 has a maximum momentary starting capacity of 2200 W but only 1800 watts running. In other words it can withstand 2200 Watts for a few seconds without blowing up, They claim it will provide 1800 watts continuous at sea level but that somewhat misleading pizza tower It won't last long at 1800 on a continual basis. Keep in mind that unlike a commercial Duty Onan generator you never want to run an inverter type generator at full load for any length of time as you'll destroy them relatively quickly. At best you want to run them at about 50% of their rated output.

Keep in mind these small inverter generators don't have oil filters so you really want to change the oil about 3 times as often as they recommend depending on how dusty of an environment you're running them in.

Measure the AC's amperage rating - should be on a dinosaur game sticker on the unit. For a window-style RV AC, expect around 10-15 amps.
