Determining the right size generator for your travel trailer involves calculating your power needs and selecting a generator that can comfortably meet them without overloading or being inefficient. Generally, most travel trailers require a generator between 2000 and 3500 watts to run essential appliances and comfort systems.
Understanding Your Power Needs: A Crucial First Step
Choosing the right generator for your travel trailer is more than just picking a random model; it’s about understanding your specific energy demands. A generator that’s too small will leave you in the dark (literally!), while one that’s too big is an unnecessary expense and fuel hog. Therefore, a careful assessment is paramount.
Making a Power Audit: Listing Your Appliances
The first step is to create a comprehensive inventory of all the electrical appliances you plan to use in your travel trailer. This list should include everything from the essentials, like your air conditioner, refrigerator, and microwave, to the conveniences such as your television, coffee maker, and hairdryer.
Next to each appliance, note its running wattage (the power required to keep it operating) and its starting wattage (the surge of power it needs when initially turned on). This information is usually found on a sticker on the appliance itself or in its owner’s manual. Starting wattage is usually much higher than running wattage, especially for appliances with motors, like air conditioners and refrigerators.
Calculating Your Total Wattage Requirements
Once you have your list, it’s time to do some math. Add up the running wattage of all the appliances you anticipate using simultaneously. For appliances with high starting wattage, like your air conditioner, use the starting wattage figure instead of the running wattage. Then, add the running wattage of the remaining appliances you plan to use concurrently. This will give you a realistic estimate of your peak power demand.
It’s wise to add a safety margin of about 10-20% to your total wattage calculation. This buffer allows for fluctuations in power draw and ensures that your generator isn’t constantly operating at its maximum capacity, which can shorten its lifespan and reduce efficiency.
Generator Types and Considerations
Now that you know how much power you need, let’s explore the different types of generators and factors to consider when making your final decision.
Inverter Generators vs. Conventional Generators
Inverter generators are generally preferred for travel trailers. They produce clean, stable power that is safe for sensitive electronics like laptops and smartphones. They are also typically quieter and more fuel-efficient than conventional generators. However, inverter generators tend to be more expensive.
Conventional generators are less expensive but produce less refined power. While they can power many appliances, they are not ideal for sensitive electronics. They are also typically louder and less fuel-efficient.
Fuel Type: Gasoline, Propane, or Dual-Fuel?
Gasoline generators are widely available and relatively inexpensive. However, gasoline can be less convenient to store and can degrade over time.
Propane generators offer cleaner burning and longer shelf life. Propane tanks are also relatively easy to store and transport. However, propane generators may be slightly less efficient than gasoline generators.
Dual-fuel generators offer the flexibility of running on either gasoline or propane. This can be a convenient option, allowing you to choose the fuel that is most readily available or cost-effective.
Noise Level: Consider Your Neighbors and Your Sanity
Generator noise can be a significant concern, especially in campgrounds. Check the decibel rating of the generator before you buy it. Look for models that are advertised as being “quiet” or have noise levels below 60 decibels. Inverter generators are generally quieter than conventional generators.
Common Mistakes to Avoid
- Underestimating Power Needs: It’s better to err on the side of having too much power than not enough.
- Ignoring Starting Wattage: This can lead to overloading your generator and damaging your appliances.
- Neglecting Maintenance: Regular maintenance is crucial for keeping your generator running smoothly and extending its lifespan.
- Overlooking Noise Level: Be considerate of your neighbors and choose a generator that operates at a reasonable noise level.
- Ignoring Safety Precautions: Always operate your generator in a well-ventilated area to prevent carbon monoxide poisoning.
Frequently Asked Questions (FAQs)
1. What is the difference between running watts and starting watts?
Running watts are the amount of power an appliance continuously needs to operate. Starting watts are the surge of power required when an appliance, especially one with a motor (like an air conditioner or refrigerator), initially turns on. Always consider starting watts when choosing a generator.
2. How do I calculate the total wattage I need for my travel trailer?
Make a list of all the appliances you plan to use simultaneously, noting their running and starting wattages. Add up the running watts, using the starting watts figure for any appliance with a motor. Add a 10-20% safety margin to this total to ensure your generator isn’t constantly running at max capacity.
3. Are inverter generators worth the extra cost for travel trailers?
Generally, yes. Inverter generators provide cleaner, more stable power, crucial for sensitive electronics. They’re also usually quieter and more fuel-efficient, making them ideal for campground use.
4. Can I use an extension cord with my generator?
Yes, but use a heavy-duty, outdoor-rated extension cord of the appropriate gauge for the amperage you’re drawing. Avoid long extension cords, as they can reduce voltage and damage your appliances.
5. Is it safe to run my travel trailer’s air conditioner on a generator?
Yes, provided your generator has sufficient starting and running wattage to handle the air conditioner’s demands. Consult your air conditioner’s specifications and ensure your generator meets or exceeds them. Consider a soft-start device for your AC unit to reduce the initial power surge.
6. How often should I service my generator?
Refer to your generator’s owner’s manual for specific service intervals. Generally, change the oil every 50-100 hours of use, clean or replace the air filter regularly, and check the spark plug and fuel filter annually.
7. Can I run my generator inside my travel trailer or enclosed space?
Never run a generator inside your travel trailer or any enclosed space. Generators produce deadly carbon monoxide fumes. Always operate your generator outdoors in a well-ventilated area, away from windows and doors.
8. What is the best fuel type for a travel trailer generator: gasoline or propane?
Both have pros and cons. Gasoline is readily available but can degrade over time. Propane has a longer shelf life and burns cleaner, but propane generators might be slightly less efficient. Dual-fuel models offer the most flexibility.
9. How do I prevent my generator from being stolen?
Use a heavy-duty chain and padlock to secure your generator to a sturdy object. Consider a generator cover to make it less visible. Some generators also have built-in theft alarms.
10. What is the difference between a generator and a portable power station (solar generator)?
A generator typically runs on gasoline, propane, or diesel and generates electricity using an engine. A portable power station stores electricity in batteries and can be charged via solar panels, a wall outlet, or a car charger. Power stations are quieter and produce no emissions but have limited power capacity compared to traditional generators.
11. How do I store my generator when it’s not in use?
Drain the fuel from the carburetor and fuel tank if storing for an extended period. Store the generator in a dry, well-ventilated area. Cover it to protect it from dust and debris.
12. What features should I look for in a travel trailer generator besides wattage?
Consider features like a low-oil shutdown to protect the engine, an electric start for convenience, a fuel gauge to monitor fuel levels, and multiple outlets to connect various appliances. Also, check the noise level rating to ensure it meets your comfort and campground requirements.
