What Generator Size for RV Do I Need?

Finding the right generator size is crucial to ensure that all your electrical appliances and systems can operate smoothly while on the road. The size of the generator you require depends on the power demands of your RV, which are typically categorized by the electrical service they offer: 30-Amp and 50-Amp RVs.

Understand Your RV’s Amperage Needs

Most RV's require either 30 or 50 amp electrical service, commonly referred to as a "shore power source." Knowing this information is crucial to finding the right generator size that can handle the same power output.

A 30-amp generator can supply up to 3,600 watts of power, while a 50-amp generator can provide up to 12,000 watts of power. However, it's essential to note that not all RV appliances and devices operate at their maximum wattage simultaneously. Therefore, it's advisable always to consider your power needs to avoid overloading or underfeeding your generator.

Furthermore, it's essential to note that running multiple appliances and devices simultaneously will require a higher generator size. In contrast, fewer devices and appliances can be supported by smaller generators. This is essential to keep in mind when selecting a generator size for your RV to avoid overloading or underfeeding power that could damage your appliances and devices.

Selecting the Right Size Generator to Run Your RV

When it comes to selecting the right generator size for your RV, there are a few expert recommendations and guidelines to consider:

  • Assess Your Power Needs: Start by evaluating the electrical appliances and devices you plan to use in your RV. Consider the wattage ratings of items like air conditioners, refrigerators, microwaves, and other essential equipment. Make a list of all the appliances you will run simultaneously to determine your total power requirements.
  • Calculate Power Consumption: Once you have identified your appliances, calculate their power consumption in watts. This information can usually be found on the appliance labels or in the user manuals. Sum up the wattage of all the appliances to get an estimate of the total power needed.
  • Consider Surge Power: Certain appliances, such as air conditioners and refrigerators, require extra power during startup, known as surge power or starting wattage. It's crucial to factor in this additional power requirement when selecting a generator size to ensure it can handle the initial surge without overloading.
  • Match Generator Capacity: The generator you choose should have a rated power output that meets or exceeds the total power requirements of your RV. It's generally recommended to have a generator that can supply at least 20% more power than your estimated needs to accommodate any power spikes or fluctuations.
  • Seek Professional Advice: If you're unsure about calculating power requirements or selecting the right generator size, it's always advisable to consult with a professional or an experienced RV dealer who can provide personalized recommendations based on your specific RV setup and power needs.

Solar vs. Propane Generators: Which is Better?

When it comes to powering your RV off-grid, two popular options stand out: solar generators and propane generators. Each option offers unique advantages and considerations, so let's delve into the details to help you determine which is better suited for your specific needs.

Solar Generators: Harnessing the Power of the Sun – The Pros

Solar generators are an eco-friendly and renewable energy solution that harnesses the power of the sun to generate electricity. They consist of solar panels that capture sunlight and convert it into usable energy stored in built-in batteries.

Here are some key benefits of solar generators:

Clean and Quiet Operation: Solar generators produce electricity without emitting harmful fumes or noise, making them an environmentally friendly and peaceful choice for your camping adventures.

Fuel Independence: With solar generators, you don't need to rely on external fuel sources. As long as the sun is shining, you have a continuous source of energy, making them highly convenient and cost-effective in the long run.

Low Maintenance: Solar generators have few moving parts and require minimal maintenance. Once installed, they typically operate silently and efficiently, with no need for oil changes or regular upkeep.

Solar Generators: Harnessing the Power of the Sun – The Cons

Dependence on Sunlight: Solar generators rely on sunlight to generate electricity. This means that their power output can be affected by cloudy days, low light conditions, or if the panels are obstructed by shade. This limitation can result in reduced power availability during unfavorable weather conditions.

Initial Cost: Solar generators typically have a higher initial cost compared to propane generators. The cost of solar panels, batteries, inverters, and installation can be significant. Although prices have been decreasing over time, the upfront investment for a solar generator can still be a deterrent for some.

Propane Generators: Reliable Power On-Demand – The Pros

Propane generators, on the other hand, utilize propane gas as their fuel source to generate electricity. They offer distinct advantages that may be more suitable for certain RV owners. Here are some notable aspects of propane generators:

High Energy Density: Propane has a high energy density, meaning it can store a significant amount of energy in a relatively small space. This allows propane generators to provide a reliable and powerful source of energy for your RV appliances and systems.

Versatile Fuel Source: Propane is widely available and can be easily sourced from various locations. This accessibility makes propane generators a convenient option, especially when camping in remote areas where other fuel sources might be scarce.

Propane Generators: Reliable Power On-Demand – The Cons

Fuel Dependence: Propane generators require a steady supply of propane fuel to operate. This means you need to have access to propane cylinders or a propane storage tank. Depending on usage, the cost and availability of propane fuel can vary, and you may need to periodically refill or replace the propane.

Noise and Emissions: Propane generators can produce noise and emissions during operation. While newer models are designed to be quieter and more eco-friendly, they still generate some level of noise and exhaust emissions. This can be a consideration if you prioritize a quieter and cleaner camping experience.

Maintenance and Storage: Propane generators require regular maintenance, including checking fuel levels, inspecting connections, and servicing the engine. Additionally, propane cylinders or tanks need to be stored safely, which may require additional space and precautions.

Recap on Solar vs. Propane Generators: Which is Better?

Deciding between solar and propane generators ultimately depends on your specific requirements and preferences. Consider factors such as your camping style, power needs, budget, and environmental concerns. Some RV owners opt for a combination of both systems to maximize their power options.

By carefully weighing the pros and cons of each option and understanding your power demands, you can make an informed decision that best aligns with your RV lifestyle. Whether you choose the clean and renewable energy of solar generators or the reliable and versatile power of propane generators, both options provide viable solutions for powering your RV off-grid.


By understanding the appropriate and right generator size for your RV and weighing the pros and cons of solar and propane options, you can make an informed choice that aligns with your power needs and travel style. Let's explore the world of RV generators and ensure you have a reliable and efficient power source for your adventures.
