Buying Guide: Gas-Fired Generator Sets
- Fuel flexibility: Tri-fuel options expand fuel availability during shortages. Consider your most accessible fuel type and the availability of natural gas lines or propane in your area.
- Power needs: Estimate essential circuits first. For whole-home backup, aim for higher running watts and a transfer-switch-ready model.
- Portability vs. capacity: Inverter-based, lighter units are easier to move but usually have lower peak power. Tri-fuel and larger displacement engines provide more sustained power for bigger loads.
- Runtime and fuel capacity: Larger tanks extend runtime but increase weight. Check fuel gauge readability for quick monitoring during outages.
- Safety features: CO sensors, low-oil shutdown, and rubber outlet covers improve safety. A CO watchdog is valuable in homes with sensitive occupants or pets.
- Outlets and transfer readiness: Ensure the generator has outlets compatible with your appliances and a transfer switch-ready configuration when wiring to a home panel.
FAQ
- What does “tri-fuel” mean and why pick it?
– Tri-fuel means the unit can run on gasoline, propane, or natural gas, offering flexibility if one fuel type becomes scarce or expensive. - Is an electric start essential?
– Electric start is convenient for quick power, especially in cold weather or during storms, but manual starting options exist on some models. - How many watts are needed for basic home backup?
– For essential loads like refrigeration, lighting, and heating, plan for 6000–9000 running watts, plus surge capacity for appliances. - What safety features matter most?
– Look for CO sensors, automatic low-oil shutdown, and robust enclosure or mufflers to reduce noise and improve safety around occupants. - Do I need a transfer switch?
– A transfer switch streamlines panel wiring and protects against backfeeding, a critical feature for permanent backup installations. - How should I store and maintain a gas generator?
– Store in a ventilated area away from living spaces. Regularly check oil levels, fuel stability, and battery condition for electric starts.
