Buying Guide
- Fuel versatility: Tri-fuel or dual-fuel models offer flexibility when fuel sources are limited. Consider the availability and cost of gasoline, propane, and natural gas in your area.
- Power needs: Calculate your essential loads (refrigeration, heating, sump pump, lighting) and select a generator with sufficient running and surge watts. A home backup scenario often benefits from 10,000–15,000 running watts for full coverage.
- Transfer switch compatibility: If you plan to connect to a home panel, ensure the generator supports a transfer switch and matches your panel’s amperage (50A, 30A, etc.).
- Runtime vs. fuel tank size: Larger fuel tanks yield longer runtimes. For extended outages, prioritize models with longer runtime at a practical load.
- Remote/automatic features: Electric or remote start adds convenience during cold weather or at night. Auto-restart after a brief outage can enhance reliability.
- CO safety and sensors: CO detectors and automatic shutoff sensors protect occupants and help meet safety requirements in enclosed spaces.
- Portability vs. durability: Portable units ease transport but may compromise tank size; stationary setups require stability and mounting considerations.
- Maintenance access: Look for readily available replacement parts and straightforward maintenance schedules to ensure long-term reliability.
- Noise and emissions: Quiet operation and EPA-certified emissions are important for neighborhoods and compliant use in various locales.
In summary, choosing between these options depends on your home size, fuel readiness, and how you plan to use the generator. For whole-home backup with flexible fueling and strong transfer-switch capabilities, tri-fuel models like the DuroStar DS13000MXT or DuroMax XP13000HX stand out. For high-capacity, transfer-switch-ready performance with robust safety features, the WEN TF1450X and Westinghouse 12500 offer compelling configurations. For smaller to mid-range needs, the PowerSmart and Generac iQ5200 provide portable, efficient choices that balance power and convenience.
