Buying Guide: Key Purchase Considerations
- Fuel flexibility: Dual- and tri-fuel options provide resilience if one fuel type is scarce. Consider fuel availability in your area and expected run times at your typical load.
- Power needs: Assess starting Watts vs. running Watts for appliances and essential circuits. Larger homes may require tri-fuel or high-watt units with robust transfer-switch readiness.
- Transfer switch readiness: For seamless automatic backup, pair your generator with an appropriate transfer switch. Check compatibility with your home electrical setup.
- Remote start and digital displays: Remote push-button starts and VFT or hour-meter displays help you monitor performance and fuel usage easily from a distance.
- Safety features: Look for CO sensors, automatic low-oil shutdown, and rugged enclosures designed for outdoor use and weather exposure.
- Runtime and fuel capacity: Larger fuel tanks extend runtimes, but consider the space and weight implications for portability or storage.
- Outlets and receptacles: Ensure outlets match your needs (RV, 30A, 50A, standard 20A duplex) and that rubberized covers protect against weather.
- Maintenance and warranty: Check engine type, cast-iron sleeves, and warranty terms. These impact long-term reliability and total cost of ownership.
