Westinghouse 13500 Peak Watt Tri-Fuel Generator
This model offers a robust tri-fuel configuration with 13500 peak watts on gasoline and strong outputs on propane and natural gas. It features a remote start via included key fob, a transfer switch-ready package, and dual 120V outlets plus a 50A RV-ready outlet. It includes a CO shutdown system and a digital hour meter for maintenance tracking, plus a heavy-duty 500cc Westinghouse engine designed for long life. Fuel capacity supports extended runtime, while safety outlets with rubberized covers reduce exposure to the elements.
WEN 14,500-Watt Tri-Fuel Generator
The TF-1450X switches among gasoline, propane, and natural gas with a simple dial. It delivers 14500 surge watts and 11500 running watts on gasoline, and lower outputs for other fuels—suitable for transferring power to essential circuits via a transfer switch. The generator operates at 120V/240V, making it compatible with most home standby needs. Its CO watchdog provides additional safety by automatically shutting down if carbon monoxide levels become dangerous. The unit is designed for mobility with a wheel kit, offering a balance of power and portability for emergencies.
Westinghouse 14500 Peak Watt Tri-Fuel Generator
This larger Westinghouse model is designed for bigger homes requiring substantial backup power. With tri-fuel capability (gasoline, propane, natural gas), it delivers up to 14,500 peak watts and 11,500 running watts on gasoline, and strong outputs on other fuels. A 9.5-gallon tank with a fuel gauge supports lengthy operation, and the heavy-duty 550cc engine withstands continuous use. The unit is transfer switch-ready to support a safe, code-compliant home installation and provides ample outlets for whole-house circuits. It serves as a reliable solution for prolonged outages while maintaining safety features and durability.
DuroStar DS13000MXT Tri Fuel Generator
The DS13000MXT is built to power an entire home during outages with 13,000 watts of tri-fuel capability. It emphasizes safety with CO awareness and a user-friendly power panel, including multiple outlets and a transfer switch-ready setup. The tri-fuel support provides fuel flexibility during emergencies or supply disruptions. This unit targets homeowners seeking a strong, all-in-one backup power solution with straightforward operation and compatibility with home electrical systems.
Westinghouse 8200 Peak Watt Tri-Fuel Inverter
This inverter-style generator combines tri-fuel capability with inverter efficiency, delivering 6600 running/8200 peak watts on gasoline, with lower outputs on propane and natural gas. It’s designed for sensitive electronics thanks to low total harmonic distortion (THD). A key feature is its transfer switch capability and multiple outlets, including a 50A outlet that supports home backup power for essential devices. The CO sensor and quieter operation make it suitable for urban or suburban settings where noise and air quality matter.
Buying Guide: Key Purchase Considerations and Comparisons
- Fuel flexibility: Tri-fuel models provide versatility during shortages, making natural gas a practical option for consistent home backup if you have natural gas service.
- Power needs: Assess running and peak watts to cover essential circuits. For whole-home support, prioritize models with 11,000+ running watts on gasoline and robust natural gas outputs.
- Transfer switch readiness: A transfer switch-ready generator simplifies safe connection to your home electrical system during outages; verify compatibility with your panel.
- Safety features: Look for CO shutdown, CO watchdog sensors, and rubber outlet covers to protect against moisture and accidental contact.
- Run time and fuel economy: Larger fuel tanks extend runtime; inverter-based models typically offer better fuel efficiency and quieter operation, beneficial for noise-sensitive areas.
- Portability vs. permanence: Portable units suit temporary outages or job sites, while larger, transfer-ready units better serve as a semi-permanent home backup solution.
- Maintenance access: Engines with cast iron sleeves and durable components tend to last longer under intermittent load; consider digital hour meters for maintenance planning.
- Safety and code compliance: Ensure models accommodate transfer switch installation by qualified professionals, and verify that any setup adheres to local electrical codes.
