Buying Guide: Key Purchase Considerations
- Fuel options: If fuel availability varies in your area, choose dual- or tri-fuel models to ensure power during shortages.
- Power needs: Compare running watts (continuous load) and peak watts (surge). For whole-home backups, ensure the running watts meet your essential circuits plus a safe margin.
- Starting method: Remote/electric start saves effort during outages; recoil start is a basic backup but may be harder in cold weather.
- Transfer switch readiness: Essential for seamless connection to home electrical systems and to prevent backfeeding.
- Safety features: Look for CO shutoff, coated outlets, and rubber outlet covers. Carbon monoxide safety is crucial for indoor or semi-enclosed spaces.
- Runtime and tank size: Larger tanks extend runtime under typical loads; plan around your blackout duration expectations.
- Weight and portability: Heavier units require stable placement and proper handling equipment; consider wheel kits and handle design.
FAQ
- What is the difference between running watts and peak watts?
Running watts are the continuous power you can draw; peak watts are the surge power available for startup of heavy appliances. - Do tri-fuel generators require special installation for natural gas?
Yes, natural gas connections may require professional setup and proper gas line sizing for safe operation. - Is remote start necessary for emergencies?
Not strictly necessary, but it improves convenience and reliability during adverse conditions or cold starts. - Can I run a whole house on these generators?
Some models can support whole-house loads if sized to cover essential circuits and with a transfer switch setup; consult a licensed electrician for exact needs. - What maintenance is required for dual-fuel generators?
Regular oil changes, spark plug checks, air filter cleaning, and fuel system maintenance are typical; follow the manufacturer’s maintenance schedule. - Are these generators safe for indoor use?
Never operate generators indoors or in enclosed spaces; always provide proper ventilation and follow safety guidelines.
