How to Choose Best Inverter Generators for 50 Amp RVs
Power Output Requirements
Calculate your RV’s total power needs before choosing a generator. Add up the running watts of all appliances you’ll use simultaneously, then add 20% buffer for startup surge.
Most 50 amp RVs need 6000-8000 running watts minimum for comfortable operation. If you run dual air conditioners or high-draw appliances, consider 9000+ watt models for headroom.
Fuel Type Flexibility
Tri-fuel generators offer maximum versatility by running on gasoline, propane, or natural gas. This flexibility ensures you can always find available fuel during emergencies or remote camping.
Dual fuel models cost less but limit you to gas and propane only. Consider where you typically camp and which fuel types are readily available in those areas.
Runtime and Tank Capacity
Larger fuel tanks mean fewer refills during overnight operation or extended power outages. Look for tanks of 7+ gallons if you need all-night runtime without interruption.
Runtime specifications are typically measured at 25% load, so actual runtime will vary based on your power consumption. ECO mode extends runtime by adjusting engine speed to match demand.
Noise Level Considerations
Campground noise restrictions typically require generators under 65 dBA. Quieter models around 60 dBA are nearly conversation-level and won’t disturb neighbors.
Inverter technology runs significantly quieter than traditional open-frame generators. Check noise ratings measured at 23 feet, which represents typical campsite distances.
Portability and Weight
Generators for 50 amp RVs typically weigh 120-150+ pounds due to their power requirements. Look for models with wheels and handles if you’ll move them frequently.
Consider where you’ll store the generator in your RV and whether you can lift it in and out safely. Never-flat wheels and telescopic handles make repositioning much easier at campsites.
Frequently Asked Questions
Can a 50 amp RV run on a 30 amp generator?
Yes, but you’ll need an adapter and must limit your power usage significantly. Most 50 amp RVs need at least 6000 watts, which 30 amp generators cannot provide, so you cannot run all appliances simultaneously.
How long will an inverter generator run on a full tank?
Most inverter generators run 10-21 hours at 25% load depending on tank size. Actual runtime decreases with higher loads, so running multiple air conditioners may reduce runtime to 6-8 hours.
What’s the difference between inverter and regular generators?
Inverter generators produce cleaner power with less than 3% THD that’s safe for electronics, run quieter, and adjust engine speed to save fuel. Regular generators run at constant speed regardless of load.
Do I need tri-fuel or is dual fuel enough?
Dual fuel covers most situations with gas and propane options. Tri-fuel adds natural gas capability for home backup or permanent installations, but costs $150-300 more and is only necessary if you plan to use natural gas hookups.
Can these generators power two RV air conditioners?
Yes, generators rated 8000+ running watts can typically handle dual 15000 BTU air conditioners plus other loads. Models under 7000 running watts may struggle with two AC units running simultaneously.
Final Thoughts
The Westinghouse 11000W Tri-Fuel offers the best overall combination of power, fuel flexibility, and reliability for serious RV users. For budget-conscious buyers, the AIVOLT 8000W delivers excellent quiet performance at the lowest price.
Choose based on your specific power needs, fuel preferences, and how often you’ll move the generator. Tri-fuel capability provides maximum flexibility but costs more upfront.
Any of these six generators will reliably power your 50 amp RV when properly sized to your electrical demands.
