Buying Guide: Key Purchase Considerations
- Fuel flexibility: Tri-fuel and dual-fuel models offer resilience if one fuel source is scarce or expensive. Consider your fuel availability at home and storage capacity.
- Power needs: Match peak and running watts to the appliances you plan to run. Common essentials include refrigerators, sump pumps, lights, and a modem/router. A higher running wattage provides headroom for intermittent loads.
- Transfer switch readiness: For seamless home backup, ensure the generator supports a transfer switch and has appropriate outlets for your main circuits and RV use if needed.
- Safety features: Look for CO sensors, automatic shutoff, and rubber outlet covers to protect against accidental contact and moisture.
- Starting method: Electric start adds convenience, especially during outages. Recoil backups and remote start provide flexibility when the battery is depleted or inaccessible.
- Runtime and tank size: Larger tanks extend runtime, but weigh more and require space. Balance runtime with the available storage area.
- Noise level: Inverters and certain models offer quiet operation, which is beneficial for RVs, camping, and neighborhoods with noise restrictions.
- Emissions and compliance: Check CARB or EPA compliance if you plan to use the generator in regulated areas or on jobsites.
