Having problems running AC from inverter.
I'm converting a cargo trailer into a camper. Over the weekend, I tried to install an AC unit. The unit that I bought requires 8.8 amperes at 115 volts. My inverter is an 1800 watt trip lite that I ha...

Those things are not cheap!!
What I'm finding when I google that looks like about $300. For not a lot more, I could upgrade to a larger inverter.
The 1800 watt unit that I have is supposed to support a peak of 3600 watts for starting motors, just like you're talking about. 3600 watts should be about 30 amperes. How much do I need to start a 9 amp motor?
Wouldn't a spike in draw cause a momentary dip in the low voltage supply, at least until the inverter cut off. I'm not seeing any dip at all. Even setting my volt meter to record max and min voltage, its, recording a min that's still 13+ volts, and it's watching on millisecond time scales.
Even “if” you get an inverter large enough to run the ac, it would require a “very” large battery bank to make a sustained run. I haven’t “crunched” the numbers....but, it would require many typical batteries!
