I have a 9 kw Diesel 3 cylinder single phase Perkins Marine generator that I put a radiator on to make it a land generator. I have a house in La Paz Mexico (just north of Cabo San Lucas). I built a house there and have three air conditioners that are (2) two tons and a single 5 ton air conditioner. I vbrought down the generator after being frustrated with the sparatic power situation. We are on the grid but the power goes off often. I have my electrician run power directly into the main breaker to my garage where I have a female plug and a large breaker. When I go the main breaker on the street and fire up my generator, all the lights, washing machine and dryer as well as my water pump work just fine. My 2 ton units and 5 ton units don't work. I'm aware the five ton unit will draw too much from the generator and runnning both two ton units will have the same consequences. I tried to run just the single two ton unit and it will not power up. The light on the unit does not illuminate. There is a way to double up the wires that come from my generator to make it 240 volts. I did this and still no A/C power. Does anyone have any recommendations? I am at work at the moment and do not have any technical data in front of me for the generator. Do I need a different phase generator?? Any assitance is greatly appreciated. Thanks in advance, Pete..
