Rubber-coated outlets enhance safety, and a cast-iron-sleeve engine with automatic low-oil shutdown and a digital hour meter support long-term reliability. The VFT display provides real-time voltage and frequency readouts for monitoring power flow.
Westinghouse 12500 Watt Dual Fuel — Remote Start
This model mirrors many Westinghouse dual-fuel features with 9,500 running watts on gasoline and 12,500 peak watts, plus 8,500 running and 11,200 peak watts on propane. It incorporates a remote start with a key fob, a digital hour meter, and a cast-iron sleeve engine. A standard 6.6-gallon tank supports long runtimes, and design considerations like safety outlets and a transfer-switch-ready configuration help integrate with home electrical systems. The built-in CO shutdown mechanism reduces carbon monoxide risks, making it a practical choice for whole-house backup power.
Buying Guide: Key Purchase Considerations
Power needs and fuel options: Start by listing essential appliances and their wattage. If you rely mainly on gasoline, prioritize high running watts; if you value flexibility or cost savings, prioritize dual- or tri-fuel models with propane and natural gas compatibility.
Transfer switch readiness and outlets: Choose models with transfer-switch-ready configurations and sufficient outlet types (GFCI, RV, 30A/50A) to cover your home’s circuits.
Fuel capacity and runtime: Larger fuel tanks extend runtimes, particularly for high-wattage loads. Consider predicted outage duration and whether you prefer longer runtimes at lighter loads.
Safety features: Look for CO detectors, automatic low-oil shutdown, rubber outlet covers, and reliable engine protection. These features help ensure safe operation during extended outages.
Sensor and monitoring features: Some models include digital hour meters and VFT displays for real-time voltage, frequency, and runtime data, aiding maintenance and power management.
Portability vs. stationary use: If you need portability for events or remote sites, weigh wheels and handle design. For home backup, ensure the unit is mounted and properly connected to a transfer switch.
In evaluating the five recommended options, consider your home’s size, typical outage duration, and local climate. For larger homes or areas with frequent outages, a tri-fuel model can provide maximum fuel flexibility. For homes with a strong preference for easy operation, models with remote start and straightforward maintenance features offer practical advantages. Always verify compatibility with your existing electrical panel and consult a licensed electrician before installation to ensure safe and compliant use.
