Buying Guide: Key Purchase Considerations
- Fuel flexibility: Dual fuel and tri-fuel generators offer versatility during fuel shortages and outages. Consider how long each fuel type can sustain essential circuits.
- Power output: For home backup, prioritize units with high peak and running watts to cover critical loads like refrigeration, HVAC, and lights. Ensure the 50A outlets can feed prepared circuits via a transfer switch.
- Transfer switch readiness: A transfer switch connection simplifies integration with your home’s electrical panel and minimizes manual switching risks.
- Safety features: Look for CO sensors, automatic shutdowns, and weather-resistant outlets with protective covers to prevent exposure to the elements during outages.
- Run time and tank size: Larger fuel tanks extend runtime; match to typical outage durations you anticipate and consider fuel availability in your area.
- Engine durability: Cast iron sleeves and robust OHV engines are indicators of longevity. Regular maintenance intervals should be understood before purchase.
- Noise and comfort: Inverter-based models generally run quieter and more fuel-efficient, which matters if you’ll use the generator near living spaces.
- Portability vs. stationary needs: Portable models are versatile for RVs and job sites, while transfer-switch ready units may be better for fixed home backup setups.
