Buying Guide
Power Output and Whole House Coverage
The first factor is how much power you need. A 10kW generator can run essential circuits like lights, refrigerator, and a well pump. Larger homes with central air conditioning, electric ovens, or multiple appliances may need 22kW or more.
Generac offers models from 10kW to 28kW, all with automatic transfer switches. DuroMax and DuroStar portable units deliver 13,000 watts, which can power most essentials when connected to a transfer switch. For a deeper dive on sizing, read our guide to residential standby generators.
Fuel Type and Flexibility
Standby generators typically run on natural gas or propane, offering clean combustion and lower maintenance. Generac’s Guardian and Whole Home series are natural gas or propane ready, with electronic fuel control for efficiency.
For portable options, DuroMax XP13000EH runs on gas or propane, while DuroStar DS13000MXT adds natural gas capability. Tri fuel flexibility gives you backup options during fuel shortages. Learn more about fuel choices in our best whole home generators for power outages guide.
Remote Monitoring and Control
Modern generators offer cellular or WiFi connectivity. Generac’s Mobile Link app lets you check status, receive maintenance alerts, and control the generator from anywhere. This is invaluable if you are away during a storm.
Models like the Generac 10kW and 22kW Whole Home generators include built-in cellular capability. The Guardian series adds WiFi monitoring. For a closer look, see our generac 28kW generator review.
Reliability and Warranty
Generac backs every standby generator with a 5-year limited warranty and 24/7 customer support. Features like oil level sensors, cold start performance, and weather-resistant enclosures ensure readiness in harsh conditions.
DuroMax and DuroStar portable generators use all-metal frames and copper windings for durability. The DuroStar DS13000MXT includes CO Alert for safety. For more reliability comparisons, visit our standby generators category page.
Final Thoughts
Choosing the right whole house generator depends on your home size, fuel preference, and desire for automation. For permanent, hands-free backup with remote monitoring, the Generac 10kW Whole Home Generator offers excellent value and reliability.
