8. Best Standby Generator Review – Generac 7042

Generac round off our reviews of the best standby generator appliances with the 7042, another 22kW generator from the manufacturer’s acclaimed Guardian Series. The air-coooled 7042 has no transfer switch but remains one of the best air-cooled home standby 22kW/19.5kW generators on the market. The 7042, as a generator-only proposition, is 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 your existing automatic transfer switch can be used with Generac generators.

The good thing about such situations is that the installation process is much simpler than other brands, including removable door panels, a base pad requiring only minimal ground preparation, and efficient wiring techniques.

Another point in favour of Generac’s units is that they are backed by 24/7/365 customer support, in addition to a 5,000plus-strong network of dealers across the nation.
