So, what exactly is the Generac 7040 Speed Air Cooled Home Standby Generator?  Well, it is known as one of the best standby generators for home on the market! From durability to warranty and support, the Generac 7040 Home Standby Generator is certainly two steps higher from its competitors. Take a look at its amazing high-tech features!


At first glance, it seems like this product does not live up to the Generac-brand of durability. But you’d be quite wrong! In actuality, this model takes durability to a whole new level. Unlike its competitors, this product is protected both on the inside and outside.

This best-rated home standby generator is made of durable aluminum steel that’s designed for long-lasting use. But, thanks to the RhinoCoat powder finish, this product is entirely corrosion-resistant! With this feature, you can use it at scorching days or rainy nights.

Other than that, this product’s engine is protected from overuse. Due to its pressure-lubrication feature, its engine is quite capable of long, rigorous use. It also doesn’t require much maintenance, unlike its other competitors.


With a newer model comes a newer engine. The Generac 7040 Speed Air Cooled Home Standby Generator has a new engine with twice the power. Known as the G-force engine, this engine can produce 18,000 to 20,000 watts of emergency power. This amount of electricity is enough to charge essential appliances, miscellaneous devices, and probably one whole room!


Other generators on the market are operated through a complex system of levers and pulleys. For many users, this system is too complicated and takes away the fun of standby generators. But, the Generac 7040 Home Standby Generator is quite different. It is operated by a 200-amp, NEMA 3 smart transfer switch. With a flick of a switch, this generator can provide enough power for a whole house protection.

If you are worried that this product will keep you up at night, then worry no further! This ideal standby generator for home is considered as one of the quietest generators on the market. It utilizes a special G-flex technology that reduces noise levels and fuel consumption during operation. Moreover, it has a Quiet-Test Self-test mode that further reduces its noise levels.


As a newer model, this best standby generator utilizes up-to-date technology. For example, it has a Mobile Link Remote Monitoring system that makes your generator maintenance so much easier! With this system, you can access information about your generator’s condition and maintenance status in the comfort of your mobile devices.

Its G-Force engine also uses a new technology. With its new and patented G-Flex technology, your standby generator can easily adjust its speed operation based on your home’s needs. No more manual speed and voltage adjustments; your generator can do that for you!
