Buying Guide
When choosing a natural gas generator set, consider these factors:
- Power needs: Compare surge and running watts across fuels to ensure the unit can handle your critical circuits and appliances during an outage.
- Fuel flexibility: Tri-fuel capability provides fuel redundancy, essential during shortages or price spikes. Check the availability of natural gas in your area.
- Safety features: Look for CO monitoring, automatic shutdown, and weatherproof outlets to protect occupants and equipment.
- Starting method: Electric start offers convenience, especially during emergencies. Ensure the battery and controls are accessible and durable.
- Runtime and fuel capacity: Larger tanks or efficient engines extend runtime. Consider fuel gauge visibility for maintenance planning.
- Transfer-switch readiness: For whole-home backup, confirm compatibility with your transfer switch and electrical panel.
- Noise and portability: For some homes, noise levels matter; wheels or handles help relocation during maintenance or non-emergency use.
- Warranty and service: A robust warranty and accessible service centers can reduce long-term ownership costs.
In sum, tri-fuel generators with CO safety features, electric start, and transfer-switch compatibility provide a comprehensive solution for reliable home backup. Evaluate your peak load, preferred fuels, and safety requirements to select the model that best meets your household’s needs.
