Best for users needing substantial peak power with reliable dual-fuel capability. Caution: heavier unit may require a larger setup area and stable surface for operation.
Buying Guide
What to consider when shopping for a 50 amp dual fuel generator:
- Power needs: Estimate the total running watts for essential circuits and appliances. Choose a model with higher running watts if you expect concurrent loads.
- Fuel flexibility: Dual fuel adds versatility during a outage or remote work site; propane tends to offer longer shelf life than gasoline.
- RV-Ready and transfer switch readiness: If you plan to run a home transfer switch or RV hookups, verify 50A outlets (14–50R) are available and accessible.
- Safety features: CO shutoff, low-oil shutdown, and covered outlets reduce risk in enclosed spaces or during long outages.
- Runtime: Look at gallons on board and fuel efficiency metrics. Larger tanks provide longer runtimes between refueling.
- Portability vs. capacity: Some units are heavy but packed with power; consider wheel kits and handle design if you need frequent movement.
- Noise and emissions: Consider decibel levels and EPA/CARB compliance if you live in noise-restricted or emissions-sensitive areas.
Frequently Asked Questions
- What does 50A RV-ready mean on a generator?
It means the generator has an RV-ready outlet (typically a 14–50R receptacle) that can power standard RV electrical systems and can be connected to a home transfer switch when needed.
- Are dual fuel generators safer for propane than gasoline?
Propane offers cleaner emissions and longer shelf life. However, both fuels require proper storage, ventilation, and maintenance to ensure safe operation.
- What should I consider for long runtimes?
Choose models with larger fuel tanks and higher efficiency, and plan for refueling access during extended outages.
- Is CO protection essential in a generator?
Yes. CO sensors and automatic shutdown reduce the risk of carbon monoxide exposure when used in or near occupied spaces.
- Can I use a transfer switch with any 50A generator?
Most 50A outlets are compatible with commonly used transfer switches designed for 120/240V outputs. Confirm switch compatibility with your specific model.
- Which model is best for a mid-sized home?
Models with 9500–12500 running watts and a 50A outlet provide robust backup for most mid-sized homes during outages.
