Were you ever able to sort out your air conditioning
problem? I ask because I am now in exactly the "same boat": I am in Malorca, Spain
, converted one input of my shore power
from 120VAc;60 Hz, to toaccept 240VAC 50 Hz (by a Victron isolation transformer) to supply ship's systems with 110VAC @ 50hz. Most systems work except the raw water
pumps for the airconditioners which will run noisily for a while and (predictably with 50hz) run slower, become quite hot and eventually trip the breaker after a few minutes. However, if I run my 12.5KW Westerbeke generator
(that supplies 110VAC at 60Hz for ship's systems), the airconditioner pumps run quietly and stay cool. This sounded like the problem you described. I wondered if you ever found a satisfactory solution.

Is it possible to convert these 110VAC 60hz units to accept 240 VAC 50 hz by simply switching out the compressors for suitably rated ones or is it more complicated than that?
