Generator sets produce either single or three-phase power. Choose a single-phase set if you do not have any motors above five horsepower. Three-phase power is better for motor starting and running. Most homeowners will require single-phase whereas industrial or commercial applications usually require three-phase power. Three-phase generators are set up to produce 400/420 volts. Single-phase sets are 230/240. Use the low voltage to run domestic appliances and the high voltage for your motors, heaters, stoves and dryers.

Going Fully Automatic

All of our generators are partnered with a Smartgen 6120 controller system this gives the user the option of going fully automatic.
To go fully automatic add ATS & AMF HAT520 Transfer box depending on the size your electrician would only need to run the wiring between the generator, transfer box and the main switchboard. And when you lose power the generator would auto start and when the power returns the generator would auto shutdown. Note: The Transfer Box is not waterproof


Getting a generator that can handle all your power generation needs is one of the most critical aspects of the purchasing decision. Whether you are interested in prime or standby power, if your new generator can’t meet your specific requirements then it simply won’t be doing anyone any good.
