If you’re new to RVing, you’ll quickly realize that without a power source, RV camping can be difficult. You won’t be able to use your air conditioning or appliances, and your RV batteries will die after a few days. That’s why, if you’re going to camp somewhere without hookups, you’ll need an external power source!
A generator is the simplest way to start getting that extra power. If you’ve never used a generator before, they can be intimidating, but we’ve got you covered with everything you need to know to operate an RV generator.
Types of RV Generators
The first thing to understand is that generators are classified into two types: portable generators and onboard generators that are already wired into your RV.
Onboard generators are standard on most motorcoaches, including Class A and Class C. They’re also showing up in larger fifth-wheel trailers. These are usually built into the RV and can be activated with a switch from inside the vehicle. They usually (but not always!) run on the same fuel that your RV’s engine does. Depending on the model, onboard generators can run on gas, diesel, or propane. If your car has a generator built in, check the owner’s manual to find out what kind of fuel it uses.
The other type of generator is a portable one, which is plugged into your trailer via the shore power cord. These generators come in a variety of sizes and power outputs, and they run on various types of fuel. If you don’t have an onboard generator, this is the best option.
Selecting an RV Generator
Even though most new motor homes have generators built in, trailer owners should think about buying a portable generator before boondocking.
Portable RV generators are not one-size-fits-all; there is much to consider when selecting the best generator for your rig. You must first consider the type of fuel. Portable generators can run on gasoline, diesel, propane, or a combination of the three.
You should also consider the size and power output of a portable generator to determine whether it will be sufficient to power your rig. Consider how frequently you will use the generator, how many appliances you want to run, the size of your unit, and so on. Don’t forget about the noise level! Inverter generators are more expensive but much quieter.
Generator Security
Now that you have your generator, go over some basic safety precautions. First, make sure your vehicle has a carbon monoxide detector. When generators burn fuel, they produce carbon monoxide, a highly poisonous but odourless gas. You don’t want that blowing back into your rig, so check your CO detector. For the same reason, never run your generator in a closed garage or anywhere with poor ventilation.
Keep an eye on the weather and conditions when using a portable generator. Avoid getting your generator wet or running it in the rain or snow. If you’re dry camping in the desert or a dry forest, however, be careful where you put it because heat or sparks could start a wildfire.
You’ll also want to keep your generator secure while travelling so it doesn’t overturn. Generators must be stored upright, so find a secure location where they will not slide around or fall over while driving.
Finally, while it is not a safety concern, be mindful of where you use your generator. Dry camping in the middle of nowhere won’t be an issue, but running a generator all night in a crowded campground will result in irritated neighbours. Many campgrounds don’t allow generators to be used at night, so check with the campground before you turn it on.
How to Use an RV Generator
After all of that, we’re finally ready to turn on your generator. The first step is to pull out your trusted user manual and read through the instructions for your specific generator model! Although each RV generator is unique, we will provide a general guide on how to use them. Turn to the user manual for all details on operating and troubleshooting your generator!
How Does an Onboard Generator Work?
Using an onboard generator is usually quite simple. Most RVs have a “Start/Stop” switch on the control panel that allows you to turn the generator on and off. Depending on the rig and generator, there may be a “Prime” button that will prime the generator before turning it on, or you may need to hold the “Stop” switch to prime the generator. Check your user manual to learn how to prime and start your specific generator, as well as how long it needs to be primed. Once primed, press and hold the start button for a few seconds until you hear the generator start.
How Does a Portable Generator Work?
Portable generators require a few additional steps to operate, which is why it’s critical to read the user manual to learn exactly how to use them (seeing a pattern here?).
First, unload the generator and move it at least 5–10 feet away from your rig. To prevent fumes from entering your rig, make sure the exhaust output is facing away from it. Depending on where you’re camping and how loud the generator is, you may want to move it further away from your trailer. Check the oil and fuel levels to ensure you have enough for the duration of your run. Plug your shore power cable into the power supply port on the side of your rig while everything in the trailer is turned off.
It’s now time to start the generator. To prime and start your specific generator model, consult your owner’s manual and follow the manufacturer’s instructions. Allow it a minute or two to warm up after it has been primed and started. Plug the other end of the rig’s power cable into the generator once it has warmed up and started. Depending on the type of generator, a dogbone adapter may be required to connect the cable. And voila, your rig now has 120-volt power!
