Window AC 5000btu

If you do decide to try it, could you perhaps take some pics? So we can...uh...maybe get some....er....ideas and such......

 

I'm confused reading this post, no AC unit plugs into an inverter that uses 4.5volts(I think you mean amps?) But otherwise I'd expect to see 450-600 watt draw, thats do able at a constant, but the compressor start up is much, much higher and would likely exceed the inverter's capacity, meaning the AC would draw 2000watts+ on start up. I'd love to be wrong, for your comfort... but I don't think the numbers work.

Instead I'd look at the price of fixing the trucks AC, what's wrong there?

 

Well then there's no point to get an ac if you still need to idle.

@scottied67 has a portable ac, he might help

 

Watts are what counts when it comes to inverters. Add up all the watts that the items you are running at the same time are rated at and add 10% and as long as your inverter is rated for that amount or more you are OK.

With something like an AC unit with a motor and compressor, TheDude1969 is correct, it will draw a lot more power when starting up so you may want to figure for 25% - 35% more instead of 10%.

 

I installed a 6000 btu window AC through my back wall and it will run about 3 hours on just the inverter and standard battery bank when it is hot. On temperate nights around 80 degrees, it can run all night cycling on and off as needed to keep truck at 73 degrees just on batteries.
I added a 3100 champion generator and it powers the AC at idle consuming very little just over a gallon per night or up to 10 nights on the extended run tank.

 

what size inverter do you run, would be helpful to the OP?

 

I just got done mounting a champion 4000 on my truck , 5000btu window unit going in tomorrow when the mounting plate is ready.
I'll let ya know how it works .

 

My inverter is a 2000 watt puresine. I purchased this size more for microwave almost 2yrs ago.
It is bigger than needed for a window ac

I am also confused..... to use the inverter, you need to idle the truck. if you're idling the truck, why aren't you using the truck AC?
