Fuel Type

Generators can be powered by different fuel types, including gasoline, diesel, propane, or even solar energy. Each fuel option has its own advantages and considerations. Gasoline-powered generators are commonly available and more affordable, but they require regular refueling.

Diesel generators are fuel-efficient and offer longer run times but are generally more expensive. Propane generators are quieter and cleaner-burning, but propane may be less readily available in some areas. Consider your fuel preferences and availability when choosing a generator.

Noise Level

Another crucial factor to consider is the noise level of the generator. RV camping often involves staying in campgrounds or RV parks where noise restrictions may be in place. It’s important to choose a generator that operates at a noise level that won’t disturb you or your fellow campers. Look for generators labeled as quiet or low-decibel models for a more peaceful camping experience.

Portability

Portability is a significant consideration, especially if you plan on moving your RV frequently. Generators come in various sizes and weights, and it’s important to choose a generator that is lightweight and compact enough to fit your RV storage space and easy to transport when needed. Consider the size and weight of the generator to ensure it aligns with your mobility needs.

Budget

Your budget is another critical factor when choosing a generator for your RV. Generators come at different price points depending on their power output, fuel type, and additional features. It’s essential to set a budget and find a generator that offers the best combination of features and performance within your price range.

3. Determining the Generator Size You Need

Determining the right generator size for your RV involves calculating the minimum wattage requirement, surge wattage requirement, and total wattage requirement.

Minimum Wattage Requirement

The minimum wattage requirement refers to the amount of power needed to run essential appliances and systems in your RV. These typically include items like lighting, water pumps, and basic electronic devices.

To calculate the minimum wattage requirement, add up the wattage ratings of all your essential appliances and systems.

Surge Wattage Requirement

In addition to the continuous power consumption, some appliances require a higher wattage during startup. This surge wattage requirement accounts for the initial power surge needed to get the appliance running.

Appliances like air conditioners, refrigerators, and microwaves often have a surge wattage requirement. Make sure to consider the highest surge wattage rating among your appliances when calculating the generator size you need.

Calculating Total Wattage Requirement

To determine the total wattage requirement, simply add up the minimum wattage requirement and the highest surge wattage requirement. This total wattage requirement will give you an idea of the size and power output your generator needs to meet.

It’s always recommended to choose a generator with a slightly higher power output than your total wattage requirement to ensure a reliable power supply.
