Buying Guide: Key Considerations For Choosing A Natural Gas Generator Set

  • Fuel flexibility: Prioritize models that support gasoline, propane, and natural gas or offer a high-wattage natural gas option. Tri-fuel units provide the broadest contingency planning for outages and fuel supply shifts.
  • Power output vs. load needs: Determine your essential load profile (refrigeration, heating, sump pumps, lighting) and compare running watts. Higher peak watts matter for startup surges on appliances like air conditioners.
  • Runtime and fuel storage: Consider fuel tank capacity and expected run time on each fuel. Inverter-based models often optimize fuel use but may have smaller tanks; traditional open-frame units usually offer longer runtime per fill.
  • Transfer switch readiness: If you plan whole-home backup, ensure the generator is transfer-switch ready or compatible with an interlock kit. This simplifies safe, automatic transfer when the grid fails.
  • Safety features: Look for CO shutdown, low-oil shutdown, and robust overload protection. Inverter technology with peak-to-running watt balance helps protect electronics from surges and damage.
  • Ease of starting and maintenance: Remote electric start improves reliability during outages. Maintenance indicators, tool-free cartridge filters, and accessible spark plugs help with routine upkeep.
  • Portability vs. stationary needs: For frequent relocation or limited space, portable tri-fuel units with compact footprints are useful. For stationary backup, dedicated transfer-capable models provide a steadier installation.
  • Accessories and compatibility: Confirm that hoses, quick-connect fittings, and conversion kits are compatible with your chosen generator model, and ensure the fittings meet local safety codes.
  • Noise and emissions: If you’re in noise-sensitive areas, inverter-based tri-fuel generators generally offer quieter operation and lower exhaust emissions, which can be a consideration for daily use.
  • Budget and warranty: Balance upfront cost against warranty length, service options, and parts availability to ensure long-term reliability and support.
