Determining the right size generator for your travel trailer hinges on accurately calculating your electrical needs and choosing a model that can comfortably handle your peak power demands. Generally, a generator in the range of 2000 to 4000 watts is sufficient for most travel trailers, but a detailed assessment is essential to avoid overloading the generator and potentially damaging your appliances.
Understanding Your Power Needs
Before rushing out to buy a generator, it’s crucial to understand how much power your travel trailer consumes. This involves identifying the appliances and devices you plan to use simultaneously and calculating their wattage requirements. Let’s break down the process:
1. Identifying Your Appliances
Start by making a list of every electrical appliance you might use in your travel trailer. This includes:
- Air conditioner (AC): Often the biggest power consumer.
- Microwave: Another significant draw, especially on startup.
- Refrigerator: Typically runs intermittently, but still needs consideration.
- Television: Relatively low power consumption.
- Lights: LED lights are energy-efficient, but incandescent bulbs consume more.
- Coffee maker: Another high-wattage appliance used periodically.
- Electric heater: Very high power consumption and often not needed if the travel trailer has a propane heater.
- Hair dryer: Similar to a coffee maker, used for short periods but high wattage.
- Phone/Laptop chargers: Relatively low power consumption.
- Water heater: Can be electric or propane; electric versions draw significant power.
2. Calculating Wattage Requirements
Now that you have your list, determine the wattage each appliance requires. Look for a sticker on the appliance itself, or consult the manufacturer’s specifications. Note that some appliances list their starting wattage (surge wattage) and their running wattage. The starting wattage is the higher number and represents the power needed to initially turn on the appliance. The running wattage is the power needed to keep the appliance running continuously.
Create a table like this:
| Appliance | Running Wattage | Starting Wattage |
|---|---|---|
| ——————- | ————— | —————- |
| Air Conditioner | 1500 W | 3000 W |
| Microwave | 1000 W | 1500 W |
| Refrigerator | 200 W | 600 W |
| Television | 100 W | 100 W |
| Lights (LED) | 20 W | 20 W |
| Coffee Maker | 800 W | 1000 W |
| Hair Dryer | 1200 W | 1500 W |
| Phone/Laptop Chargers | 50 W | 50 W |
| Total |
3. Determining Peak Power Needs
This is the most critical step. You need to figure out the maximum power you’ll need at any given time. Add up the running wattage of all the appliances you anticipate using simultaneously. Then, add the highest starting wattage of any single appliance to account for the surge power.
Example:
Let’s say you plan to use the air conditioner (starting wattage 3000 W, running wattage 1500 W), refrigerator (running wattage 200 W), lights (running wattage 20 W), and charge your phone (running wattage 50 W) at the same time.
- Total running wattage: 1500 W + 200 W + 20 W + 50 W = 1770 W
- Highest starting wattage (air conditioner): 3000 W
- Peak power needs: 1770 W + (3000 W – 1500 W) = 3270 W
Therefore, in this scenario, you’d need a generator that can handle at least 3270 watts. It’s always wise to add a buffer of around 10-20% to ensure the generator isn’t constantly running at its maximum capacity.
Choosing the Right Generator
Once you know your peak power needs, you can start researching generators. Consider these factors:
- Wattage Rating: Make sure the generator’s continuous wattage rating exceeds your calculated peak power needs.
- Fuel Type: Gasoline, propane, and dual-fuel generators are common. Consider the availability and cost of each fuel type. Propane tends to be cleaner burning.
- Noise Level: Look for generators with low noise levels, especially if you’re camping near others. Measured in decibels (dB), lower is better.
- Weight and Portability: Consider the generator’s weight and size, especially if you need to move it frequently.
- Inverter Technology: Inverter generators produce cleaner power, which is safer for sensitive electronics. They are also usually quieter and more fuel-efficient.
- Features: Some generators have features like electric start, remote start, and low-oil shutoff.
FAQs: Your Generator Questions Answered
Here are 12 frequently asked questions to further guide you in selecting the ideal generator for your travel trailer:
1. What happens if I overload my generator?
Overloading a generator can cause it to shut down, damage the generator itself, or damage the appliances connected to it. Most generators have built-in overload protection, but it’s always best to avoid exceeding the rated wattage.
2. Is it better to get a generator that’s too big or too small?
It’s generally better to get a generator that’s slightly too big than too small. An undersized generator won’t be able to power all your appliances, while an oversized generator will run less efficiently if only lightly loaded, but it won’t damage your appliances. You also have room to add other electric devices to your travel trailer as time goes on.
3. Can I use an extension cord with my generator?
Yes, but use a heavy-duty, outdoor-rated extension cord with the correct gauge (thickness) for the amperage. A long, thin extension cord can cause voltage drop, which can damage appliances.
4. How often do I need to service my generator?
Refer to the manufacturer’s recommendations for service intervals. Typically, this involves changing the oil, cleaning or replacing the air filter, and inspecting the spark plug. Regular maintenance will extend the life of your generator.
5. Can I run my generator inside my travel trailer?
Never run a generator inside your travel trailer or any enclosed space. Generators produce carbon monoxide, a deadly odorless and colorless gas. Always operate the generator outdoors in a well-ventilated area, away from windows and doors.
6. Are inverter generators worth the extra cost?
Inverter generators are generally more expensive, but they offer several advantages, including cleaner power, quieter operation, and better fuel efficiency. They are a good investment if you have sensitive electronics and value peace and quiet.
7. How long will a generator run on a tank of gas?
The runtime depends on the size of the fuel tank, the load on the generator, and the generator’s efficiency. Check the manufacturer’s specifications for estimated runtime at different load levels.
8. Can I parallel two generators together to increase power?
Yes, some generators are designed to be paralleled, which means you can connect two identical generators to double the available power. This requires a special parallel cable. Check if your generator supports this feature.
9. What is the difference between a conventional generator and an inverter generator?
Conventional generators produce AC power directly, which may not be as clean or consistent. Inverter generators convert AC power to DC power and then back to AC power, resulting in cleaner, more stable power that is safer for sensitive electronics.
10. Do I need to ground my generator?
Yes, grounding your generator is important for safety. Refer to the manufacturer’s instructions for proper grounding procedures. This typically involves connecting the generator’s grounding terminal to a grounding rod driven into the earth.
11. How do I store my generator when not in use?
Drain the fuel tank and carburetor if you’re storing the generator for an extended period. Use a fuel stabilizer to prevent fuel from degrading. Store the generator in a clean, dry place, covered to protect it from dust and moisture.
12. What are some reputable generator brands for travel trailers?
Some popular and reputable generator brands for travel trailers include Honda, Yamaha, Champion, Generac, and Westinghouse. Research different models within these brands to find one that meets your specific needs and budget.
By carefully assessing your power needs and considering these factors, you can confidently choose the right size generator to power your travel trailer and enjoy a comfortable and convenient camping experience. Remember to always prioritize safety when operating and maintaining your generator.
