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...

If there's nothing wrong with the AC unit, nothing wrong with the inverter, and nothing wrong with the low voltage supply to the inverter, what could be the problem?
The inverter and supply powering it just doesn't have the capacity to deal with the A/C's LRA (Locked Rotor Amp) rating which will be many times it's running amps. As an example it's not uncommon that a typical roof mount 13,500 BTU A/C would have an LRA of 60+ amps even though it's total running amps may be well under 15 smps. Just because you have a smaller A/C doesn't mean it's exempt from this sudden high current demand that is overwhelming your inverter. Equipping the A/C with a Micro-Air Easy Start soft starter kit would likely solve this issue.
