Why Choose Generac for Your Home Standby Generator?
When you invest in a standby generator, you need to know it will be ready when the power goes out. That’s why GEM Electrical recommends Generac for residential backup power. With more than 65 years of experience in power generation, Generac offers automatic operation, remote monitoring and a wide range of standby generators designed to keep homes powered during an outage.

Automatic Backup Power
When utility power is interrupted, the system automatically detects the outage and starts the generator. The automatic transfer switch moves your home from utility power to generator power, supplying electricity to the systems your generator has been configured to support.
Once utility power returns, the system automatically reconnects your home to the grid and shuts the generator down.
Generac Generator Sizes for Different Homes
There isn’t one generator that works for every property. A home that only needs essential systems protected will have very different power requirements from a homeowner looking for broader whole-home backup.
Generac offers residential standby generators across a range of capacities, including air-cooled systems from approximately 10 kW to 28 kW, with larger options available where additional capacity is required.
The important part isn’t choosing the biggest generator. It’s determining how much power your home actually requires and what you want operating during an outage.
Natural Gas or Propane Backup Power
Generac home standby generators can operate using natural gas or liquid propane, depending on the model and installation. Where natural gas is available, the generator can be connected to the home’s existing gas supply. Properties without natural gas may be able to use an appropriately sized propane system instead.
Because the fuel source is permanently connected, there’s no need to continually refill the generator with gasoline during an extended outage. When the power goes out, your backup power system is ready without hauling fuel cans, running extension cords or manually setting up a portable generator.
Warranty and Long-Term Support
A standby generator is a long-term investment, so manufacturer support matters long after the installation is complete. Generac home standby generators include manufacturer warranty coverage, with current standby generators carrying a five-year limited warranty. Generac also provides access to product documentation, maintenance information, replacement parts, technical resources and qualified service providers.
Proper installation and ongoing maintenance are important parts of protecting your generator and keeping it ready for the next outage.
