The Generac Guardian Home Standby Gas Generators have now been officially approved as a Type A appliance in all Australian states. What does that mean for you? It means the Generac Guardian 8, 10, 13 & 20 kVA Gas Generator models can be easily installed like a simple gas appliance using a Type A gas fitter for installation and certification. The gas generators by Generac are also rated for operation in areas with low natural gas pressure.


Reliable Gas Generators For Standby Power


With an automatic transfer switch, your gas generator will switch on as soon as it detects that mains power has failed, meaning your home or business is never without power, even if you’re away. It’s that simple! The gas generator is designed to sit outside your home or business, like an air con unit, so it doesn’t take up any space inside.
