Gas Generators Portable

Gas generators run on LPG or natural gas, so there's no petrol or diesel to store, and a mains gas connection means no refuelling at all. Paired with an automatic transfer switch, a gas standby generator such as the Generac home backup range starts within seconds of a power cut and keeps running until the mains returns.

LPG and natural gas

Natural gas generators connect to your existing mains gas supply and run for as long as the supply lasts. LPG generators run from gas bottles or a bulk LPG tank, which suits properties without mains gas. Output can differ between the two fuels, so check the LP and NG ratings in each model's specifications.

Gas standby generators for homes

A gas standby generator is permanently installed outside the home in a weatherproof, sound-attenuated enclosure. With an automatic transfer switch it starts itself, so nobody needs to be home when the power goes. The transfer switch, gas connection and installation are separate from the generator, and we can supply and install the complete system.
