Buying Guide
- Fuel flexibility: Tri-fuel units offer greater resilience during fuel shortages. Consider your access to gasoline, propane, and natural gas in your area.
- Transfer switch compatibility: Confirm that the generator has a transfer switch ready receptacle layout (L14-30R or similar) to simplify installation with a whole-house transfer switch.
- Power needs: Evaluate your essential circuits and total load. Larger homes may require higher peak and running watts, while smaller homes may suffice with mid-range outputs.
- Runtime vs. tank size: Long runtimes are convenient, especially in prolonged outages. Compare tank capacities and fuel efficiency at typical loads.
- Safety features: CO sensors, automatic shutoffs, and sturdy enclosures protect occupants and equipment during operation.
- Portability vs. stationary design: Wheel kits and lightweight builds improve mobility, but permanent installs may be preferred for frequent outages.
- Outlets and connectivity: Ensure the unit offers the necessary 120V and 240V receptacles, including RV-ready outlets if needed.
- Maintenance and serviceability: Opt for engines with easy oil changes and accessible air filters; check warranty terms and local service options.
