Imagine a storm rolls in, the lights flicker, and suddenly your home goes dark. The refrigerator stops humming, the sump pump falls silent, and your family’s comfort hangs in the balance. That’s when a standby generator becomes your home’s silent guardian.

Buying Guide
Power Output: Matching Your Home’s Needs
The first step in choosing a standby generator is calculating your power requirements. A 10kW unit like the Generac 10kW Whole Home Generator can handle essential circuits such as lights, a refrigerator, and a well pump. For whole-house coverage, consider a 22kW or larger model. Think about your home’s square footage, HVAC system, and any high-demand appliances.
Fuel Type: Natural Gas vs. Propane
Most standby generators run on natural gas or liquid propane. Natural gas offers unlimited runtime if your supply remains intact during an outage, while propane provides flexibility and can be stored in tanks. Models like the Kohler 20kW unit allow simple field switching between fuels. Consider your home’s existing fuel infrastructure and local availability.
Automatic Transfer Switch: Seamless Power Transition
An automatic transfer switch (ATS) detects a power outage and starts the generator within seconds, then safely switches back to utility power when it returns. Many generators, including the 20kW Standby Generator with 200amp TS, include a 200-amp ATS for whole-home coverage. Ensure the ATS matches your electrical panel’s capacity.
Monitoring and Control: Stay Connected
Modern generators offer remote monitoring via Wi-Fi or cellular connectivity. Apps like Generac’s Mobile Link let you check generator status, receive maintenance alerts, and even start the unit from your phone. This feature is especially valuable if you travel frequently or have a vacation home. For more on monitoring options, see our generac 22kW maintenance kit review.
Final Thoughts
After reviewing these top contenders, our recommendation comes down to your specific needs and budget. For whole-house protection with robust power and advanced monitoring, the Generac 22kW Whole Home Generator stands out as a reliable workhorse. If you’re looking for a more budget-friendly option that still covers essential circuits, the Generac 10kW Whole Home Generator offers excellent value. Both models include automatic transfer switches and cellular connectivity, ensuring you’re never left in the dark. Whichever you choose, investing in a standby generator brings peace of mind during storm season and beyond.
