Buying Guide: Key Considerations For 50 Amp Dual Fuel Generators
- Fuel flexibility: Dual-fuel capability lets you choose gasoline for peak power or propane for longer runtime and cleaner emissions. Consider your typical outage duration and fuel availability when deciding.
- Power needs: 50A RV-ready outlets indicate substantial load capacity. Match running watts and peak watts to your home’s electrical load, including central AC, sump pumps, and essential circuits.
- Transfer-switch readiness: If you plan to connect to a home panel, ensure the unit is transfer-switch ready and compatible with your panel type. This simplifies safe, automatic switching during outages.
- Safety features: Look for CO sensors, low-oil shutdown, and RO/UV protection on outlets. A CO alert helps prevent dangerous fumes in enclosed spaces.
- Runtime and tank size: Larger tanks extend run time between refuels. Compare fuel capacities with rated watts to estimate continuous operation during outages.
- Starting method: Remote electric start and recoil/back-up options improve reliability. Keep spare keys or remotes accessible for quick startup.
- Portability and noise: Heavier units deliver more power but may require a stable installation. If you need mobility, consider wheelkits and weight, and review local noise regulations.
- Outlets and compatibility: Ensure the generator provides necessary outlets (50A RV, 30A, 20A household) and that the plug configurations match your transfer switch or RV hookup.
Frequently Asked Questions
- What is a 50A dual fuel generator best for?
– It suits large homes, RVs, and job sites that require high surge power and a dedicated 50A RV outlet, along with the flexibility to run on gasoline or propane. - Which fuel is better for longer outages?
– Propane can be stored longer and may offer longer runtime for the same tank size, but gasoline generally provides higher peak power for short bursts. - Do all 50A dual fuel generators require a transfer switch?
– Not all do, but using a transfer switch improves safety and simplifies connection to a home panel during outages. - Is CO safety important on portable generators?
– Yes. CO sensors and auto-shutdown features reduce the risk of carbon monoxide exposure, especially in enclosed spaces or sheds. - Can I run these generators indoors?
