Westinghouse 11000 Peak Dual Fuel Portable Inverter Generator
The Westinghouse 11000 Peak Watt Dual Fuel inverter generator combines high power with flexible fuel options. With 9000 running watts on gasoline and 8100 on propane, it stays within a compact footprint for a machine of this capability. It includes a remote start, multiple transfer switch ready outlets, and a 50A receptacle for serious backup loads. The CO sensor and low THD design protect electronics and ensure stable performance for sensitive devices. Run times approach 17 hours on a large fuel tank, depending on load.
Westinghouse 8200 Peak Watt Tri-Fuel Inverter Generator
The Westinghouse iGen8200TFc is a versatile tri-fuel inverter with emergency home backup capabilities and a 50A outlet. Gasoline offers 6600 running/8200 peak watts, propane provides 5940 running/7380 peak, and natural gas delivers 5280 running/6560 peak watts. Inverter technology optimizes fuel use and reduces noise, making it suitable for nighttime operation in residential areas. A transfer switch-ready configuration supports whole-home loads, while the unit maintains quiet operation and integrated safety sensors for peace of mind.
Westinghouse 10000 Peak Watt Portable Open Frame Inverter
This 10000 peak watt model provides robust gasoline-powered backup with a 50A transfer-ready outlet. It features a remote start with multiple ignition options, a digital VFT display for real-time voltage and runtime, and a propane-compatible design as a secondary option. The four GFCI outlets add convenience for daily power needs, while the 5.28-gallon tank offers a practical runtime for extended outages. The unit emphasizes safety with rubber-covered outlets and automatic low oil shutdown.
Westinghouse 12500 Watt Dual Fuel Home Backup Generator
The 12500-watt dual fuel powerhouse delivers substantial backup capacity with 9500 running watts on gasoline and 11200 on propane. Remote start, 50A-capable outlets, and a 6.6-gallon tank with a fuel gauge support longer runtimes. The included transfer switch-ready configurations and robust engine with a durable cast-iron sleeve ensure reliable performance for critical loads such as refrigerators, sump pumps, and essential electrical circuits during outages.
Westinghouse 13500 Peak Watt Tri-Fuel Home Backup Generator
The 13500-peak tri-fuel unit is designed for heavy-duty backup power with three fuel options. Gasoline provides around 10500 running watts, propane 9500 running watts, and natural gas 8500 running watts. It includes a remote start, transfer switch-ready outlets, and a 50A RV-capable configuration for simultaneous high-power tasks. Built-in safety features include a CO shutdown and a digital hour meter to monitor usage and maintenance needs.
Buying Guide: Key Considerations For 50 Amp Inverter Generators
- Fuel flexibility: Tri-fuel options enable continuity when a single fuel source isn’t available. Consider how you will use propane, natural gas, or gasoline for long outages or remote worksites.
- Power and outlets: A dedicated 50A outlet (L14-30R or 14-50R) is essential for high-load appliances and transfer-switch installations. Check running watts to ensure your critical loads fit within the generator’s capabilities.
- Inverter technology: Look for true inverter systems with regulated voltage and low total harmonic distortion (THD) to protect sensitive electronics such as TVs, computers, and chargers.
- Remote start and convenience: Remote key fobs, push-button starts, and recoil options can affect ease of use during outages or on job sites.
- Runtime and tank size: Larger fuel tanks extend runtimes under load. Compare gallons per hour at your expected load to estimate daily usage.
- Safety features: CO shutdown sensors, rubber outlet covers, and automatic low-oil protections minimize risks in homes and outdoor locations.
- Noise level: Inverter generators are typically quieter than traditional open-frame units. Consider noise restrictions in residential zones and hours of operation.
- Transport and storage: Wheels, handles, and a robust frame help with mobility. Factor weight and size into storage plans and vehicle fitment.
- Warranty and service: Look for comprehensive coverage and easy access to service centers to minimize downtime after purchase.
- Transfer switch compatibility: Ensure the unit supports a transfer switch kit or interlock solution compatible with your home’s electrical panel for safe whole-home operation.
