Westinghouse iGen8200TFc Tri-Fuel Inverter Generator
The Westinghouse iGen8200TFc combines inverter efficiency with three-fuel flexibility to back up homes, offices, and essentials. Gasoline operation provides 6600 running watts and 8200 peak watts; propane delivers 5940 running and 7380 peak; natural gas runs at 5280 and 6560 watts respectively. It’s designed for lower fuel consumption and reduced noise, aiming for around 60 dBA at 25% load. A 50A transfer switch-ready outlet supports critical loads like air conditioning and refrigerators during outages. Inverter technology maintains clean, safe power for electronics and small appliances, while the unit remains parallel-capable for extra output if needed.
Westinghouse iGen11000TFc Tri-Fuel Inverter Generator
This 11,000-watt tri-fuel inverter powers whole-home backup with inverter-grade performance and quiet operation. Gasoline delivers 9000 running/11000 peak watts; propane provides 8100/10000 watts; natural gas offers 7200/8800 watts. The unit features a 50A transfer switch-ready outlet plus a twist-lock option and a GFCI 120V outlet, all with rubberized weather protection. Its inverter platform minimizes fuel consumption for longer runtimes between fills and maintains clean power less likely to harm sensitive electronics. Remote start adds convenience for routine testing or rapid response during outages.
WEN TF1450 Tri-Fuel Generator
The WEN TF1450 provides a robust 14,500 surge watts and 11,500 running watts, with three-fuel compatibility for versatile power during emergencies. It operates at 120V and 240V, making it suitable for standard home transfer switches and higher-demand setups. The electric start simplifies startup, and the unit is designed for frequent backup use with a heavy-duty engine. The ability to switch fuel sources on a dial makes it practical for regions with variable fuel availability, while the inverter approach helps keep voltage and frequency stable for electronics and communication devices during outages.
Westinghouse iGen12500 Peak Watt Tri-Fuel Generator
With 12,500 peak watts and 9,500 running watts on gasoline, plus higher outputs on propane and natural gas, this tri-fuel model targets larger homes and generators-ready setups. It includes remote start via key fob, a 6.6-gallon fuel tank with a fuel gauge, and multiple transfer switch-ready outlets, including 30A and 50A configurations. The unit emphasizes safety and convenience with rubber-covered outlets and a CO sensor. Its engine and design prioritize long runtimes, parallel operation, and real-time monitoring of voltage, frequency, and runtime to assist with maintenance planning and outage response.
WEN TF1050iX Tri-Fuel Inverter Generator
The WEN TF1050iX offers a 10,500-watt surge powered by a tri-fuel engine, with 8,550 running watts, suitable for transfer switches and emergency backup. It supports 120V/240V configurations and includes the Watchdog CO shutdown sensor to automatically shut down if carbon monoxide is detected. The unit is designed for versatile fuel use, enabling dependable power when natural gas or propane is more readily available than gasoline. It provides a practical balance between output and portability, suitable for occasional home backup and job-site reliability.
Buying Guide
Key purchase considerations for triple-fuel inverter generators include fuel availability, output needs, and safety features. Aim for a unit with enough peak watts to handle startup surges of essential appliances (refrigerators, AC, sump pumps) while maintaining clean power (low THD) for electronics.
- Fuel flexibility: Tri-fuel models offer gasoline, propane, and natural gas compatibility, reducing downtime when one fuel source is scarce.
- Power and efficiency: Inverter technology improves fuel economy and reduces noise, making the unit suitable for quiet neighborhood use and sensitive electronics.
- Transfer switch readiness: Outlets designed for transfer switches enable smooth integration with home electrical systems during outages.
- Safety features: CO shutdown, rubber outlet covers, GFCI outlets, and a CO watchdog are important for safer operation in enclosed or semi-enclosed spaces.
- Runtime and tank size: Larger tanks and efficient engines extend runtimes, but consider the weight and portability when choosing a model for camping or remote work sites.
Performance perspectives vary by use-case. For frequent home backup, prioritize models with higher peak watts and robust transfer-switch options. For portable outdoor use, weight, recoil or electric start, and quiet operation may be more critical. Finally, ensure the generator has the necessary outlets and configurations to match your existing transfer switch or panel setup, and check that the CO safety system meets your local regulations.
