Installing a Generator in Your RV: A Complete Guide

When it comes to boondocking and RVing off the grid, one of the biggest challenges is ensuring a reliable source of power. While most RVs come equipped with a shoreline for connecting to power at a campground, it's essential to have a generator for times when you're not staying at a park. In this guide, we will discuss everything you need to know about installing a generator in your RV, including determining the right generator size, the installation process, and important maintenance tips.

Introduction

Boondocking, or camping off-grid without access to traditional electrical hookups, has become increasingly popular among RV enthusiasts. However, relying solely on a shoreline for power won't be sufficient in these situations, making the installation of a generator a necessity. A generator provides the freedom to enjoy all the comforts of home on the road, even in remote locations. Whether you're a seasoned RVer or a beginner, understanding the power needs of an RV and installing a generator will give you peace of mind during your travels.

Understanding the Power Needs of an RV

Before diving into the installation process, it's crucial to understand the power requirements of your RV. Most RVs come with either a 30-amp or 50-amp electrical system. To determine which one you have, check the main plug of your RV. If it has three prongs, it's a 30-amp system, while four prongs signify a 50-amp system. Knowing the amperage will help you choose the right generator for your RV and avoid electrical overload.

Types of Generators for RVs

When it comes to generators for RVs, there are a few different types to consider. The two most common options are portable gasoline generators and permanently installed propane generators. Portable generators offer versatility and lower cost, but they require manual connection and fueling. On the other hand, propane generators, such as those from the Onan brand, provide a more convenient and seamless power source but may come with a higher price tag.

How to Install a Generator

Now that you have a basic understanding of the power needs and generator options, let's dive into the installation process. Installing a generator in an RV involves several steps, including determining the type and size of the generator, preparing the RV, mounting the generator, connecting fuel and power lines, and potentially adding an automatic transfer switch (ATS) for seamless power transfer.

Determining the Type and Size of Generator Needed

The first step in the installation process is determining the type and size of generator required for your RV. Consider your power needs based on the appliances and electronics you typically use while camping. A general rule of thumb is that a 3000 to 4000-watt generator is suitable for smaller RVs, while larger units with a 50-amp system may require a 5500 to 7000-watt generator for adequate power supply.

Preparing the RV for Generator Installation

If your RV is not pre-plumbed for a generator, the next step involves cutting a hole in the bottom of the RV to accommodate the generator. Ensure you measure the dimensions accurately and reinforce the area around the hole with sturdy material. If your RV comes pre-fitted for a generator, skip this step and proceed to the next.

Mounting the Generator

Once the RV is ready, the generator needs to be securely mounted in the designated space. Most RVs come equipped with a metal plate or bracket for easy installation. Cut out the designated area, insert the generator, and bolt it down firmly. Ensure there is ample space for airflow, as generators generate heat and require proper ventilation.

Connecting the Fuel Line and Power Cables

After mounting the generator, it's time to connect the fuel line and power cables. If you opted for a portable gasoline generator, install a quick disconnect for a marine fuel tank to simplify fueling. For propane generators, ensure the unit is properly set up for propane use or consider purchasing a generator specifically designed for propane. Connect the positive line to the RV's auxiliary battery system and ground the generator using appropriate grounding screws.

Installing an Automatic Transfer Switch (ATS)

To streamline the power transfer process, consider installing an automatic transfer switch (ATS). An ATS allows for seamless switching between the generator and shore power, and it eliminates the need for manual switching. Installing an ATS usually involves locating a suitable space, such as below the bottom drawer in the kitchen, and connecting the generator and shore power wires to the switch as per the provided diagram.

Pros and Cons of Using an ATS

While installing an ATS offers convenience and automatic power transfer, it's essential to consider the pros and cons before deciding if it's right for you. The advantages include a seamless transition between power sources, no manual intervention required, and the ability to continue using electrical appliances without interruption. However, ATS installation can be more expensive, requires additional wiring and components, and may be more complex to set up.

Powering the RV with Generator

Once the generator and necessary components are installed, you can begin powering your RV with the generator. Start the generator according to the manufacturer's instructions and let it run for a few minutes to stabilize. If using an ATS, the power transfer to the generator should occur automatically, allowing you to use your appliances and electronics without interruption. Remember to follow generator maintenance guidelines and refill fuel as necessary to ensure a continuous power supply.

Maintenance and Safety Tips for RV Generators

To ensure the longevity and safe operation of your RV generator, regular maintenance is essential. Follow the manufacturer's guidelines for servicing and inspecting the generator, including oil changes, air filter cleaning/replacement, and spark plug checks. Additionally, always operate the generator outdoors in a well-ventilated area to prevent carbon monoxide buildup. Consider installing a carbon monoxide detector inside your RV for added safety.

Alternative Power Options for RVs

While generators are a popular choice for RV power supply, they are not the only option. Depending on your needs and preferences, you may consider alternative power sources such as solar panels, lithium battery systems, or even wind turbines. Each alternative power option comes with its own set of pros and cons, and research and careful consideration are necessary to determine the best fit for your specific RVing style.

Conclusion

Installing a generator in your RV is a valuable upgrade that enables you to enjoy the comforts of home while off-grid. By understanding your RV's power requirements, choosing the right generator, and following the installation steps, you can ensure a reliable and consistent power source during your travels. Whether you opt for a portable gasoline generator or a permanent propane installation, investing in a generator will enhance your boondocking experience and open up endless possibilities for adventure on the road.
