How to Choose Inverter Generators for RVs
Power Output Requirements
Calculate your RV’s total power needs before buying a generator. Add up the wattage of all appliances you’ll run simultaneously, then add 20% for surge capacity.
Air conditioners typically need 2000-3500 watts, while refrigerators use 600-800 watts. Smaller RVs can operate on 2000-3000 watts, but larger rigs need 4000-6000 watts or more.
Fuel Type Flexibility
Dual fuel generators offer significant advantages for RV travelers. Propane is often more convenient to store and has longer shelf life than gasoline.
Gasoline typically provides more power output, while propane burns cleaner and runs quieter. Tri-fuel models add natural gas capability for ultimate flexibility at home or RV parks with hookups.
Noise Level Considerations
Most campgrounds enforce quiet hours and noise restrictions. Look for generators rated 65 dB or lower for comfortable camping experiences.
Inverter technology inherently runs quieter than conventional generators by adjusting engine speed to match power demand. The quietest models operate at conversation levels around 60-64 dB.
Portability and Weight
Consider how you’ll transport and store your generator in your RV. Lighter models around 50-60 pounds are easier to handle but may sacrifice fuel capacity.
Built-in wheels and telescoping handles help with heavier units over 70 pounds. Compact dimensions matter for storage in RV compartments or truck beds during travel.
Safety Features
Carbon monoxide sensors are essential safety features that automatically shut down generators when CO levels become dangerous. Never run a generator inside your RV or in enclosed spaces.
Low oil shutdown protects the engine from damage, while overload protection prevents electrical system damage. Fuel shutoff extends engine life by clearing the carburetor before storage.
Frequently Asked Questions
What size inverter generator do I need for my RV?
Most RVs need 3000-4000 watts for basic operation including lights, refrigerator, and outlets. If you want to run a roof air conditioner, you’ll need at least 3500-4000 watts starting capacity.
Can I run my RV air conditioner on an inverter generator?
Yes, but you need sufficient wattage. A 13,500 BTU RV air conditioner typically requires 2800-3000 running watts and 3500-4000 starting watts. Choose a generator with at least 3600-4000 peak watts.
Is propane or gasoline better for RV generators?
Propane offers longer shelf life, cleaner burning, and easier storage, making it ideal for occasional RV use. Gasoline provides more power output and faster refueling, better for frequent high-demand use.
How long can an inverter generator run continuously?
Most inverter generators run 8-14 hours continuously at 25% load. Runtime decreases at higher loads. Always allow cooling periods during extended use and never exceed manufacturer recommendations.
Do I need a transfer switch for my RV generator?
No, RVs typically use a simple plug connection to the generator through the RV’s shore power inlet. Transfer switches are primarily for home backup power installations.
Final Thoughts
The Champion 4000-Watt Dual Fuel generator offers the best overall value with its ultra-quiet operation and exceptional propane runtime. For budget shoppers, the PowerSmart 4400-Watt delivers solid performance under $300.
Consider your power needs, fuel preferences, and budget when choosing. Dual fuel capability and CO sensors are worth the investment for safety and convenience.
Match your generator’s capacity to your RV size and typical usage patterns for the best experience on the road.
