The XP13000EH operates at 13,000 watts (gas) and supports propane as an alternative fuel, with electric start and transfer-switch readiness. Choose this if you want versatility for temporary outages or RV-ready power during trips. Caution: As a portable unit, it isn’t a fixed standby solution and requires manual startup during outages.
Westinghouse 12500 Watt Dual Fuel
Best for balanced performance with dual-fuel capability and transfer-switch readiness. It delivers 9,500 running watts and 12,500 peak watts on gasoline, with propane output around 8,500 running watts and 11,200 peak watts. Remote start and various outlets enhance versatility. Limitation: Gasoline runtime may be shorter under heavy loads; propane results depend on cylinder size and load.
Buying Guide: Key Considerations For Gasoline Home Backup Power
What size generator do I need?
Assess your essential circuits and approximate total wattage. A whole-home standby system is typically chosen for larger homes with high loads, while portable dual-fuel models fit smaller to mid-sized homes or for targeted back-up needs.
Do I want portable or standby?
Portable dual-fuel generators offer flexibility and lower upfront cost but require manual operation. Standby generators automatically start during outages and connect to a transfer switch, offering seamless power restoration.
Is dual-fuel important?
Dual-fuel units work on gasoline or propane, giving more fuel options during emergencies. Gasoline provides higher peak wattage; propane often has longer shelf life and cleaner burn in some climates.
What about fuel efficiency and runtime?
Look at running watts, tank size, and fuel consumption rates. Larger tanks and smarter control systems reduce the frequency of refueling during outages.
What about monitoring and remote features?
Cellular monitoring and mobile apps enable remote performance checks and maintenance alerts. Subscriptions may be required for some advanced features.
Installation considerations
Standby generators require professional installation and a transfer switch. Ventilation and noise levels are practical factors in residential settings.
Outlets and safety features
Ensure the generator provides standard household outlets, RV connections, and transfer-switch readiness. Look for safety features like CO shutdown, oil level monitoring, and weather-resistant enclosures.
FAQ
- What is the difference between running watts and peak watts? Running watts indicate continuous power, while peak watts reflect the surge the unit can handle for short periods, such as starting appliances.
- Should I choose a dual-fuel generator? Dual-fuel offers flexibility with fuel sources, beneficial during shortages, but may cost more upfront and require more maintenance.
- Do all standby generators require professional installation? Yes, most standby units need professional installation and a compliant transfer switch for automatic operation.
- Can I monitor a generator remotely? Many modern Generac models support cellular monitoring via an app, with some features requiring a subscription.
- Is a larger generator always better? Not always. Choose based on essential circuits, space, noise tolerance, and budget to avoid over- or under-sizing.
- How long can a generator run on a tank? Runtime depends on tank size, load, and fuel type; high-load periods shorten runtime significantly.
