How to Choose an RV Generator

Buying a generator for your RV is different from choosing one as a home backup generator. You have to think more about its portability, installation and noise level.

These are the factors you need to consider before choosing the perfect portable generator for your RV.

Storage Space

Conventional portable generators are not the smallest machines so make sure that you have enough space in your RV to store it safely while driving. Make sure that the generator won’t be sliding around and is easy enough to pull out.

If you already have limited space then consider 2 smaller inverter generators instead of one big conventional portable generator. This not only saves space but is often also easier to install.

Power Requirements

Make a list of all the electrical devices in your RV and their power requirements. Aim for a generator with a capacity that is about 20% more than your minimum power requirement from that list.

Don’t forget to check the surge power, too. Also, consider whether you really need all appliances running at the same time.

Noise Level

In the silence of nature, noise travels faster so a generator may seem even louder on a campsite. Certain national parks and campsites may also have their own noise restrictions so make sure that your chosen generator falls within the noise limits.

Inverter generators are always the safer bet when it comes to low noise levels. Though they are not completely silent, a difference of 10 decibels already makes a huge difference in noise levels.


Depending on where you are heading, you might not have fuel readily available for your generator. If you enjoy spending time in remote areas then it is wise to choose a generator that is fuel-efficient.

Try to keep a few extra gallons in your RV as a reserve, in case of emergencies. For an even more environmentally-friendly solution, find a portable generator that you can link up to solar panels.
