When the power goes out, the Generac 24kW Home Standby Generator restores power automatically—helping keep your home comfortable, protected, and running normally through outages. Designed for extended run times and demanding conditions, this model combines utility-quality power (less than 5% THD), advanced monitoring, and a durable, sound-attenuated enclosure for reliable, quiet operation.
This 24kW standby generator runs on natural gas (NG) or liquid propane (LP vapor) and is ideal for homeowners who want dependable whole-home backup power with modern controls, remote monitoring, and strong motor-starting performance for essential systems and large loads.
A properly sized Generac 24kW Home Standby Generator can support many of a home’s critical and high-demand circuits—often including:
Heating equipment and fans, sump pumps, well pumps
Refrigeration and freezers
Lighting and receptacles throughout the home
Home office and electronics
Select HVAC systems and other motor loads (application dependent)
(Final coverage depends on your home’s electrical load and the installation design—especially for large HVAC and multiple motor loads.)
Automatically starts during an outage and supplies power through your transfer switch configuration.
Built for standby use during utility outages.
True Power™ Electrical Technology with less than 5% Total Harmonic Distortion (THD) helps provide utility-quality electricity for electronics and micro-chip based appliances.
Cellular connectivity is standard, with Wi-Fi™ and Bluetooth™ capabilities
Monitor generator status, readiness, maintenance alerts, and more through compatible mobile applications.
Installers/technicians use a dedicated mobile service app for setup and service functions.
G-Force™ 1000 Series engine is purpose-built for extended run times
Hydraulic lifters for reduced maintenance
Electronic fuel and ignition control (EFIC) and electronic governor
Sound-attenuated enclosure designed to withstand winds up to 150 mph (241 km/h)
Quiet-Test™ low-speed exercise option
Adjustable exercise duration: 5–20 minutes (5 minutes factory default)
Listed for installation as close as 18 in (457 mm) from a structure (must still be located away from doors, windows, and fresh air intakes and installed to local code).
