Features include remote start, ATS readiness, CO sensor, and low THD safe for electronics. Best for RVs and whole-home backup with long runtimes and protection for electronics.
Who it’s best for: users needing a quiet, efficient, long-running tri-fuel solution with strong protection for electronics and ready-to-connect features. Choose this if you want extended runtime and safe power for delicate devices.
Limitations: may be heavier and require more space due to a larger fuel capacity.
Buying Guide: Tri-Fuel Generators For Your Needs
Fuel flexibility matters: Tri-fuel generators let you switch between gasoline, propane, and natural gas. If your primary outage risk includes natural gas availability, prioritize models with proven NG compatibility and stable running watts on NG fuel.
Noise and operational efficiency: Look for inverter generators with quiet operation (often measured in the mid-60s dBA, or lower at load). Inverter technology adjusts engine speed to match demand, improving fuel efficiency and reducing noise compared to traditional open-frame units.
Power output vs. load: Compare peak watts and running watts across fuels. For home backup, running watts are more important. If you plan to power high-draw appliances, choose models with higher running watts on your preferred fuel and adequate outlets for essential circuits.
Safety features: CO shutdown sensors protect occupants by automatically stopping the engine if CO levels rise. A bonded-neutral 120V/240V configuration helps with transfer switches and compatibility with home electrical panels.
Convenience: Remote start, electronic push-button starts, and included hose kits for propane or natural gas streamline setup. Consider the weight, wheel kits, and handle design for portability if you need to move the unit between locations.
Fuel availability and cost: Propane and natural gas typically offer more stable long-term fuel availability, while gasoline is widely accessible. Factor running time per tank and burn rate to determine how often you may need to refuel during an outage.
