Labatt...as you size the generator for the AC remember to factor in the AC water pumps, and higher amp requirements at startup. Our 8.5kw ran a 16k + 12K without a peep...I'm not sure what kind of leeway a 5kw unit will give you on a 16+5 so perhaps the AC mfr. can spec that out for you including start up and the pumps.
