Westinghouse 12500 Watt Dual Fuel Backup Generator
The Westinghouse model runs on gasoline or propane, offering 9500 running watts and 12500 peak watts on gas, or 8500 running and 11200 peak on propane. It features a remote start with a key fob, plus electric and recoil start options. A 6.6-gallon tank delivers up to 12 hours of runtime, and the unit includes essential outlets: two GFCI 120V 5–20R, a 30A transfer switch-ready 120V L14-30R, and a 50A RV-ready 14–50R with safety rubber outlet covers. Its 457cc heavy-duty engine includes automatic low-oil shutdown and a digital hour meter for real-time status. This generator is best for larger homes or properties needing strong, flexible backup power with transfer-switch readiness. Caution: heavier and bulkier to move, and propane efficiency may vary with temperature.
WEN 4,750-Watt Dual Fuel Generator (DF475T)
The WEN DF475T switches between gasoline and propane with a simple dial, delivering 4750 surge watts and 3800 running watts on gas, or 4350 surge and 3500 running watts on propane. It supports 120V and 240V output, making it suitable for transfer switches and emergency backups. An electric start powers the 224cc four-stroke OHV engine with a key turn. This option is best for smaller homes or apartments where a compact, cost-effective dual-fuel solution is desired. Limitation: lower overall power may not support a full electric home during extreme outages.
DuroMax XP13000EH 13,000-Watt Dual Fuel
The XP13000EH delivers 13,000 watts and features dual-fuel capability for maximum flexibility in outages. DuroMax positions this line as a versatile option for powering an entire home during storms or extended outages. It emphasizes robust engine design and a focus on power reliability for whole-home backup. Best for homeowners who want substantial wattage with dual-fuel convenience. Caution: dual-fuel units tend to be larger and heavier, which can affect moveability and storage space.
Generac 22kW Whole Home Generator
This option is a high-end standby generator with automatic backup power and cellular monitoring. It offers whole-house protection, ensuring refrigeration, heating/cooling, lights, and connectivity stay uninterrupted during outages. Features include remote monitoring via Mobile Link and weather-activated operation, with propane or natural gas readiness. Best for premium homes seeking automatic, remote-managed power without manual intervention. Limitation: higher upfront and installation complexity, often requiring professional setup for permanent installation.
Oxseryn 4400-Watt Inverter Generator
The Oxseryn model provides 4400 peak watts and 3400 running watts, with 2x120V outlets and a 30A RV outlet. It includes 12V DC output and up to 14 hours runtime at 25% load. An inverter enhances electricity quality and fuel efficiency. Ideal for emergency household use or RV-ready scenarios, especially when quiet operation and fuel economy matter. Caution: lower continuous power compared to larger portable dual-fuel units, so not suitable for powering a full home during long outages.
Buying Guide
What to consider when choosing a generator for an all-electric home:
- Power requirements: Assess your home’s essential circuits and total watts needed during an outage. For full-home backup, aim for models in the 8000–22000 running watt range depending on appliances and climate control.
- Fuel options: Gasoline offers easy refueling, propane provides longer shelf life, and dual-fuel gives flexibility during emergencies. Consider fuel availability and storage space.
- Starting mechanism: Electric start is convenient for frequent outages; remote start adds extra ease during cold weather.
- Transfer switch compatibility: If you plan to connect to a home transfer switch, ensure the generator has matching receptacles and is transfer-switch ready.
- Automation and monitoring: Cellular or Wi-Fi monitoring helps track status and maintenance, reducing manual checks during outages.
- Portability vs. permanence: Standby generators are installed and remain in place, while portable units are movable but require manual setup.
- Safety features: Look for automatic low-oil shutoff, overload protection, and weatherproof outlets with rubber covers for outdoor use.
FAQ
- What size generator do I need for a full-electric home?
Determine total running watts of essential circuits. A typical full-home backup may require 8000–22,000 watts, depending on climate control and appliances. - Is dual-fuel preferable for long outages?
