Westinghouse 12500 Watt Dual Fuel Home Backup Generator
This generator delivers 9500 running watts and 12500 peak watts on gasoline, and 8500 running watts with 11200 peak on propane. It includes remote Electric Start with a key fob for convenient startup and is transfer switch ready, with a 30A and a 50A outlet option for larger home circuits. Best for homeowners needing dependable back-up power for essential appliances and HVAC during outages. A potential limitation is its size and weight, which reduce portability compared to smaller units.
DuroStar DS13000MX 13,000-Watt Dual Fuel Generator
Equipped for high-demand needs, this 13,000-watt unit supports both gasoline and propane. It comes with remote electric start and is transfer-switch ready, making it a solid choice for whole-home protection or a job site needing substantial power. It also includes a CO safety feature for added protection. Choose this if you anticipate frequent power outages or larger appliances running simultaneously; note that it’s best for a solid, fixed setup rather than tight spaces due to its size.
AIVOLT 7500 Watt Dual Fuel Generator
This model delivers 7500 peak watts and 6300 running watts on gasoline, with 6800 peak and 5800 running watts on propane. It includes a 50A RV-ready outlet (NEMA 14-50R) and a CO Watch-Guard system for safety. It’s ideal for RV owners and light-to-moderate home backup tasks. Best for those who want robust RV compatibility and a strong safety package, but it may be less suitable for very large home loads compared with higher-wattage units.
AIVOLT 11250W Dual Fuel Inverter Generator
This inverter generator runs 11250W on gasoline and 10570W on propane, with 9000W and 8540W respectively, and features a remote start for convenient operation. It is CARB compliant and EPA certified, including an auto-shutoff feature for high CO levels. Best for homeowners who need quiet operation and clean power for sensitive electronics, though its inverter design may limit total surge compared to traditional open-frame models for very large loads.
WEN DF1100T Dual Fuel Generator
This WEN model features 11,000 surge watts and 8,300 running watts on gasoline, with a 240V/120V capability and a user-friendly electric start. It’s a more affordable option with transfer-switch readiness, suitable for moderate home backup or RV use. One limitation is that it may be noisier than premium inverter models, which is a factor for quiet-living scenarios or noise-restricted environments.
Buying Guide: Key Considerations For 220V 50 Amp Generators
- Power needs: Assess essential vs. non-essential loads to determine wattage requirements. For whole-home backup, target units with at least 8,000 running watts and 14-50R or higher outlets for 50A service.
- Fuel type and availability: Dual-fuel models offer flexibility during fuel shortages. Consider propane stability for long-term outages and gasoline for maximum power.
- Transfer switch readiness: If you want seamless home backup, ensure the unit is transfer-switch ready or compatible with your existing transfer panel.
- Safety features: Look for CO shutdown, low-oil shutdown, and reliable overload protection. Inverter generators provide cleaner power for electronics; open-frame units usually deliver higher surge watts.
- Portability vs. capacity: Heavier, higher-watt units offer more power but trade portability. Consider wheel kits and handles for easier movement.
- Noise and emissions: Inverter models tend to be quieter and emit fewer pollutants; non-inverter units may be louder and less fuel-efficient.
