I have a Honda 2500w contractor generator. I tried running the AC on my '85 Excella. It's a 15000 btu unit ( I think). If I started on fan then went to low cool then to high cool it would start the compressor and run ( and cool ). BUT, after about 20 min I found the plug ( 30a adapter to 20a ) was way toooooo hot. If the compressor shut off I doubt that it would re-start. So my scientific analysis is that the 2500w generator is NOT able to handle the load. I now have an '01 Excella and have not tried to see. Maybe one day I will. I'm wondering if the newer units are more efficient and less stress on the generator.
