The Ultimate Buying Guide for RV Generators
Choosing the right generator for your Recreational Vehicle (RV) is a big decision. It powers your lights, microwave, and air conditioning when you are far from an electric hookup. This guide helps you pick the best one for your adventures.
Key Features to Look For
Several features make an RV generator great. Think about what you need to run at the same time. This helps you choose the right size.
Power Output (Wattage)
Generators are rated in watts. You need enough watts to start and run your appliances. Air conditioners use the most power. Check the starting (surge) watts and the running watts for all your devices. A good rule is to add up the running watts and add an extra 10% for safety.
Inverter Technology
Inverter generators produce “clean” power. This power is safe for sensitive electronics like laptops and TVs. They are also usually quieter than traditional generators.
Noise Level (Decibels – dB)
No one wants a loud machine. Look for generators rated under 60 dB for quiet operation. This is important, especially when camping near others.
Fuel Type
Most RV generators run on gasoline or propane (LPG). Some can run on both (dual-fuel). Propane stores longer and is often easier to find at campgrounds. Gasoline runs hotter and might be slightly more efficient for pure power.
Important Materials and Build Quality
The materials used in a generator affect how long it lasts and how well it handles the road.
- Engine Quality: Look for well-known engine brands. A sturdy engine core means fewer breakdowns.
- Frame and Casing: The outer casing should be made of strong, weather-resistant metal. This protects the engine from rain, dust, and road debris.
- Copper Windings: Inside the alternator, copper windings handle heat better than aluminum. Copper lasts longer and provides more consistent power delivery.
Factors That Improve or Reduce Quality
Quality isn’t just about the parts inside. How the generator operates matters a lot.
Quality Boosters:
- Automatic Voltage Regulator (AVR): This keeps the power steady, protecting your RV appliances.
- Low-Oil Shutoff: This safety feature automatically turns the engine off if the oil gets too low, preventing serious damage.
- Easy Maintenance Access: If you can easily reach the oil drain plug and air filter, you are more likely to keep up with maintenance.
Quality Reducers:
- Cheap Plastics: If too many moving parts or exterior panels are made of thin plastic, they often break quickly.
- Unregulated Output: Generators without good voltage regulation can send surges to your RV, damaging electronics.
User Experience and Use Cases
How you plan to use your RV dictates the best generator type.
Portability vs. Built-In
Portable Generators: These are smaller, lighter, and you can use them away from the RV. They are great for weekend campers or those who use their RV infrequently. Setup requires you to carry them out and connect heavy cords.
Built-In (In-Frame) Generators: These are permanently mounted under the RV. They are much quieter and start with the push of a button inside the coach. They are best for full-time RVers or those who camp extensively.
Starting Your A/C Unit
If you need to run your rooftop air conditioner, you must check the generator’s surge wattage. Small, quiet inverter generators might struggle to start a single large A/C unit. Larger, built-in models usually handle this job easily.
10 Frequently Asked Questions (FAQ) About RV Generators
Q: What is the difference between an inverter and a conventional generator?
A: Inverter generators make clean, stable electricity, which is safe for electronics. Conventional generators are often louder and produce power that can sometimes harm sensitive gadgets.
Q: How much wattage do I need for a standard RV?
A: Most small to medium RVs need between 2,000 and 3,500 running watts. If you have one A/C unit, aim for at least 3,500 watts.
Q: Can I run my generator while driving?
A: Built-in generators are designed to run while you drive for topping off batteries or running the A/C while moving. Portable generators should never be run inside a moving vehicle.
Q: How often should I service my RV generator?
A: Most manufacturers recommend an oil change after the first 20 hours of use, and then every 100 to 150 hours of operation, or once a year if you don’t use it often.
Q: Is propane better than gasoline for my RV generator?
A: Propane stores indefinitely and is usually cleaner burning. Gasoline can go bad over time, which can clog the carburetor in older generator models.
Q: Why is my generator running but not producing power?
A: This often means the circuit breaker on the generator itself has tripped. Check the generator panel first and reset the breaker.
Q: What is “surge wattage”?
A: Surge wattage is the extra burst of power the generator can provide for a few seconds when a large appliance, like an A/C unit, first starts up.
Q: Can I use a small portable generator to power my whole RV?
A: You can use a small portable generator, but you must use a transfer switch or a heavy-duty extension cord. You usually cannot run everything at once, so you must choose which appliances to power.
Q: Do I need a special transfer switch for a portable generator?
A: Yes, if you are connecting a portable generator to your RV’s main shore power inlet, you need an external manual transfer switch. This keeps your generator power separate from the campground power.
Q: Are solar panels a good replacement for an RV generator?
A: Solar panels are great for quiet, low-power needs like charging phones and running lights. They cannot replace a generator when you need high power, like running an air conditioner on a hot day.
