Buying Guide: Key Purchase Considerations
- Power needs and peak vs running watts: For whole-home backup, aim for 2x the expected running load during peak events to avoid overloads.
- Fuel flexibility: Dual- or tri-fuel units offer freedom when gas or propane is scarce; consider propane availability in your area.
- Safety features: CO sensors, automatic low oil shutdown, and overload protection reduce risk during use in occupied spaces.
- Outlets and transfer switch readiness: Ensure the generator includes a variety of outlets and is compatible with an automatic transfer switch (ATS) for seamless power transfer.
- Run time and fuel capacity: Larger tanks extend runtimes during outages; balance run time with weight and portability for practical use.
- Noise and portability: While higher power often means louder operation, look for models with idle control and rubber outlet covers for safer, quieter performance.
- Maintenance and service: Choose brands with broad service networks and readily available parts, to minimize downtime.
- Warranty and support: Review coverage length and what it includes, especially for critical home backup applications.
