Another unit from the Generac stable, the 22kw 7043 model is a little louder still, at 67 dBA, but this is still relatively low, especially when you consider that the Generac 7043 Guardian Series is also the largest air-cooled generator on the market, boasting all the features and capabilities that you would expect from a manufacturer of Generac’s renown.

It’s also cheaper than many of the best liquid cooled generators (the 7043 is air-cooled), and also utilises the brand’s innovated combined engine and alternator, using powertrain technology to attain it 22kw output. It also consumes less fuel than many of the other generators in its class.

Another of the best standby generators on the market is the Generac 7042, another 22kW generator from the manufacturer’s acclaimed Guardian Series. The 7042 has no transfer switch, but at 67dBA is one of the quietest of standby generator units, and one of the best air-cooled home standby 22kW/19.5kW generators.

This appliance is probably most suitable for someone who already has an automatic transfer switch installed on their property, although it would be recommended that you consult a Generac dealer on whether an existing automatic transfer switch can be used wit the 7042 or any Generac unit.

However, the the installation process is much simpler than other brands, the installation kit includes removable door panels, a base pad requiring only minimal ground preparation, and efficient wiring techniques. All Generac units are backed by 24/7/365 customer support, in addition to a 5,000+-strong nationwide dealer network.
