7kW 8kW 9kW Home Standby Generators for Essential Power
Home Essentials Automatic Home Standby 7kW Generator or 8kW Generator or 9kW Generator
A Generac 7.5kW PowerPact Home Standby Generator for Backup Power
Powering the entire house isn't for everyone. Fuel considerations, upfront cost, and necessity govern most home standby generator decisions. If all family needs or want is power for essentials, 7kW to 9kW generators power critical and essential circuits with an automatic transfer switch that limits which circuits receive power. Many small homes don't need a larger generator to power everything, including small air conditioners. A standby generator installation makes a permanent connection to the home through an Automatic Transfer Switch (ATS). Manufacturers offer standby generator and ATS packages that save the consumer money and ease installation with a switch and generator designed to work together.

7kW 8kW 9kW Generator Fuel Considerations
What fuel will your generator use? Natural gas is widely available, less expensive than other fuels, enjoys delivery to small and large municipalities through a network of pipelines.
While “widely available” makes it convenient for most people, it doesn't mean everywhere. Rural areas, small towns far from pipelines, and areas with unstable geography often don't have access to natural gas.
Natural gas also carries less energy than propane, which means that many generators produce less power on natural gas than on liquid propane. In the following sections, compare the generator capacity on propane vs the capacity on natural gas. If you're using natural gas, make sure your purchase decision includes the generator capacity when running on natural gas.
For example, if you need a 9kW generator and you're using natural gas, consider buying a 10 kiliowatt model with a rated capacity of 9kW on natural gas.
Propane is also widely available. It is stored on your property in a large tank that commonly holds between 100 and 1000 gallons. The right size tank will mean the difference between fuel for a few days, or a few weeks. It generally costs more than natural gas. A local propane company truck will pump it into your tank until it's 80 percent full (20 percent allows the liquid to evaporate and provide the necessary pressure.) Propane's cost tends to run higher.
