Pro Tip: This model requires a 12-Volt Group 26R (540 CCA) or Group 35R (650 CCA) battery—commonly found at automotive or hardware stores.


FAQ: Generac Generator Cost & More

  1. How much does a Generac 18kW Generator typically cost?
    • Generac generator cost can vary depending on local installation charges, permitting fees, and optional accessories like cold-weather kits. Contact X Factors Motorsports for a tailored quote.
  2. Will this generator run my entire home?
    • Yes, with the 200-Amp Service Rated Transfer Switch, it’s designed to handle a standard home’s full electrical load, including 5-ton A/C units.
  3. Is professional installation required?
    • For safety and warranty compliance, a licensed electrician or plumber should handle the fuel and electrical connections.
  4. What fuel options are available?
    • This generator runs on either LP Propane or Natural Gas, making it highly versatile in urban and rural settings.
  5. Can I monitor it remotely?
    • Absolutely. Mobile Link remote monitoring is included, allowing for real-time updates and alerts straight to your phone or computer.

How big of a house will an 18kW generator run?
An 18kW generator is typically suitable for medium to larger-sized homes (around 2,000 to 3,000 square feet), depending on the specific appliances and HVAC systems in use. It can handle essential circuits such as air conditioning (up to 5-ton units), water heaters, kitchen appliances, and more—though total coverage depends on individual load requirements.


What can an 18kW Generac generator run?
An 18kW Generac generator can power the majority of a home’s essential needs, including:

  • Central air conditioning (5-ton or smaller)
  • Refrigerators and freezers
  • Electric water heaters
  • Most lights and outlets
  • Sump pumps and well pumps
  • Home electronics like TVs and computers

For specific details, calculate your total running wattage and starting/surge wattage to ensure the generator can cover all simultaneous loads.


What size Generac do I need for a 2000 square-foot house?
Many 2,000 square-foot homes can be sufficiently covered by a 14kW to 20kW standby generator, depending on how many high-demand appliances (like multiple A/C units or electric ranges) are in use. Conduct a thorough load analysis or consult a professional electrician to match the generator size to your specific home’s power needs.


How loud is a Generac 18kW generator?
Generac’s 18kW generators typically produce about 65 dBA under normal operating load, which is comparable to the sound of a running dishwasher or normal conversation. In Quiet-Test mode, the noise can drop to around 55 dBA, significantly reducing audible sound during routine self-tests.
