Hi Cooter,

With 1180 watts can you run your roof air from an inverter?

I most certainly could, but my inverter won't start the 15K A/C even though I installed a larger capacitor on it. Neither my Honda EB3500 or Yamaha 2800i will even start it! It must be a power hog.... I find it interesting that I can run it at home on the 15A plug without low voltage, but even that Honda generator with it's rated 23A+ output hates it!

I was toying with a smaller (8-10K) roof unit or a split for the bedroom for those warm/humid nights while on the road, but I really don't want to loose my roof vent or add more weight. As much s I need AC, it really isn't worth it yet.

I'm currently looking into the new 3K Magnum MSH3012M Hybrid inverter that will boost the incoming AC to start that bad boy and give me a little larger charger. My last trailer with a 360watts solar, Freedom 20 inverter, and 4 Trojan T105's would run the 13.5 AC for quite a while.

Not sure what larger capacitor you installed.
What might help is add a kick start kit, a HD electronic potential relay and start cap. And remove the current start cap if it already has one. Actually that might start you right up. Worth a try. A kick start kit cost around $30-40. As long as you're in there, might want to check/test the mfd on the run cap to make sure its in spec.

Let me know what a/c make and model#, and what compressor make and model# you have in your a/c and I might be able to make a suggestion on whats the best start assist kit to buy for your application.
