Planning to camp off-grid? Discover the differences between onboard and portable RV generators, how much power you actually need, and how to choose the right fuel.

Onboard Generators: The "Built-In Powerhouse"

If you love convenience and want a "set-and-forget" power source, an onboard generator is the way to go.

The Set-and-Forget Source: These generators are permanently integrated directly into your RV's chassis and electrical system, meaning you never have to haul heavy external units or mess with extra power cords.

How It Works: They feed directly off your RV's main fuel tank, whether your rig runs on gasoline, diesel, or propane. With a simple push of a button from your indoor control panel, the generator fires up and starts producing electricity.

Why It Matters: Onboard units offer incredible convenience. You can easily run your air conditioners to keep the cabin cool while driving down the highway, and you never have to worry about protecting your generator from rain, snow, or wind.

High-Wattage Power: They typically deliver massive power, ranging from 4,000 to over 12,500 Watts, allowing you to run multiple high-draw appliances simultaneously.

Where to Find It: These are standard features on most motorhomes (Class A, B, and C) and high-end fifth wheels.

Portable Inverter Generators: The "Quiet Powerhouse"

If you tow a travel trailer or a pop-up camper, a portable inverter generator is likely your best friend. They have quickly become the darling of modern campgrounds, and for good reason.

The Campground Darling: Portable inverter generators offer maximum flexibility for towable RVs.

How It Works: Unlike old-school, open-frame generators that are incredibly loud and produce unstable electricity, inverter generators are highly sophisticated. They electronically throttle their engine speed up and down to match your real-time electrical demand. They also digitally refine the power by converting AC to DC, and then back to an ultra-clean AC sine wave.

Why It Matters: This digital refinement provides "clean" electricity that is safe for sensitive electronics like your laptop, smartphone, and smart TV.

Quiet and Efficient: Because they throttle down when power demand is low, they are exceptionally fuel-efficient, lightweight, and run so quietly they won't disturb you or your camp neighbors.

Where to Find It: These are standalone units from reputable brands like Honda, Champion, or Cummins that you can easily pack in your truck bed or RV storage compartment.

The Power Duo in Action: Generator & Transfer Switch

Have you ever wondered how your RV knows to switch from battery power to generator power without blowing a fuse? It all comes down to a coordinated dance between your generator and your RV's internal electrical system.

You fire up the generator: When you hit the start button, the generator's engine roars to life, spinning its alternator to produce raw AC electricity.

The "Brain" monitors the line: Your RV's Automatic Transfer Switch (ATS)—which is a combined controller and relay system—acts as the safety supervisor. It waits a few seconds for the generator's power output to fully stabilize.

The "Muscle" snaps shut: Once the ATS controller verifies that the power is stable, it triggers a heavy-duty internal relay. This relay physically switches your RV's power source from "shore power" to "generator power," safely routing electricity directly to your AC, microwave, and outlets without any risk of dangerous back-feeding.

Finding Your Fuel: Gas, Propane, or Diesel?

The fuel your generator runs on will impact how you travel, store your rig, and maintain your equipment.

Gasoline: This is the most common fuel for portable units. It’s incredibly easy to find at any local gas station. However, gas doesn't store well long-term, so you'll want to use a fuel stabilizer if your rig sits unused for long periods.

Propane (LP): Propane is an incredibly clean-burning fuel that has an almost infinite shelf life. Best of all, LP generators can tap directly into the propane tanks already mounted on your RV. Many modern portable generators are now "dual-fuel," giving you the flexibility to run on either gasoline or propane.

Diesel: This is the gold standard for large, luxury Class A diesel-pusher motorhomes. Diesel generators are highly efficient, extremely durable, and conveniently draw fuel directly from your motorhome's main diesel tank.

Sizing It Up: How Much Power Do You Need?

Before you purchase a generator or try to run every appliance in your rig, you need to understand its wattage capacity.

2,000 to 2,400 Watts: This is perfect for small travel trailers. It will easily run your lights, charge your devices, and power a small TV. However, it cannot run a standard RV air conditioner unless you pair it in parallel with a second generator.

3,500 to 4,500 Watts: This is the sweet spot for the majority of RVers. A generator in this range provides enough power to start and run a single 13,500 or 15,000 BTU air conditioner, while still leaving enough headroom for smaller appliances.

5,500+ Watts: Designed for larger fifth wheels and motorhomes, this heavy-duty power level allows you to run dual air conditioners, the microwave, and your water heater all at the same time.

Understanding Your RV Electrical System: Relays, Controllers, and More

Modern recreational vehicles depend on complex electrical systems to operate everything from lighting and appliances to slide-outs and power management equipment. Behind many of these functions are RV relays and controllers small but important components that help manage electrical power and keep different systems operating as intended.

Understanding how RV relays and controllers work can make it easier to troubleshoot electrical problems, choose compatible replacement parts, and maintain dependable performance while traveling.

What Are RV Relays?

An RV relay is an electrically operated switch used to control a circuit. It allows a low-current signal to switch a higher-current electrical load on or off. This makes relays useful in RV systems where direct control of a high-power component would be inefficient or impractical.

RV electrical relays may be used with:

Lighting systems

Electric motors

Battery circuits

Generator systems

Slide-out mechanisms

HVAC equipment

Water pumps

Other 12-volt electrical components

When a relay receives an electrical signal, it opens or closes contacts inside the unit. This action controls the flow of electricity to the connected component. Because relays are involved in many important systems, a faulty relay can cause equipment to operate intermittently or stop working completely.

What Are RV Controllers?

While relays generally switch electrical circuits, RV controllers manage more complex operations. An RV controller may receive signals from switches, sensors, or other electrical components and then direct the connected system to perform a specific function.

Controllers can be found in several areas of a motorhome or camper. Depending on the RV design, they may help manage slide-out systems, leveling equipment, lighting, battery functions, generators, or other electrical accessories.

Some controllers are designed for a single application, while others coordinate multiple functions. Because controller designs vary considerably, choosing a compatible replacement is essential.

The Difference Between RV Relays and Controllers

Although RV relays and controllers both play important roles in electrical systems, they perform different functions.

A relay primarily acts as a switch. It receives a small electrical signal and uses it to control a larger electrical load. A controller, on the other hand, can manage a sequence of operations or respond to multiple inputs.

For example, a relay might turn a motor on or off, while a controller may determine when the motor should start, stop, or change direction.

In many RV systems, relays and controllers work together. The controller manages the operation, while one or more relays handle the electrical switching required to power the equipment.

Common Signs of a Faulty RV Relay

Electrical problems can have many causes, but a damaged or worn relay may produce several noticeable symptoms. These can include:

A component that does not turn on

Intermittent electrical operation

Clicking sounds without equipment activation

A circuit that works only occasionally

Overheating around the relay

Visible corrosion or damaged terminals

Before replacing a relay, it is important to inspect related wiring, connectors, fuses, and power sources. A problem elsewhere in the electrical system can sometimes produce symptoms similar to relay failure.

Signs an RV Controller May Need Attention

A faulty controller can affect the operation of the entire system it manages. Common symptoms may include unresponsive controls, irregular operation, incomplete movement, unexpected shutdowns, or error indicators.

For example, a slide-out system may stop before fully extending, or an electrical accessory may fail to respond to a control switch. However, these symptoms do not always mean the controller itself has failed. Wiring issues, weak batteries, damaged switches, sensors, motors, and poor electrical connections can also cause similar problems.

Proper troubleshooting is important before purchasing replacement RV electrical parts.

How to Choose the Right RV Relay

Not all relays are interchangeable. Before ordering a replacement, compare the specifications of the original component with the new part.

Important details to check include:

Manufacturer and part number

Voltage rating

Current or amperage rating

Number of terminals

Terminal configuration

Mounting style

Intended application

Many RV electrical systems operate on 12-volt DC power, but this should never be assumed without checking the original component or equipment specifications.

Using the correct RV relay helps ensure that the connected circuit operates safely and reliably.

How to Select a Compatible RV Controller

Replacing an RV controller often requires even more attention to compatibility. Controllers may be designed for a particular system, manufacturer, model, or equipment configuration.

Before purchasing, check the original controller for a model number, serial number, or manufacturer identification. It can also be helpful to review the RV owner's manual or the documentation for the specific equipment being repaired.

Physical appearance alone is not enough to confirm compatibility. Two controllers may look similar while having different programming, wiring connections, or operating requirements.

Why Regular Electrical System Inspection Matters

RV electrical components are exposed to vibration, temperature changes, moisture, dust, and regular use. Over time, these conditions can contribute to loose connections, corrosion, worn terminals, and component failure.

Periodic inspections can help identify problems early. Check electrical connections for signs of corrosion, heat damage, loose wiring, or damaged insulation. Keeping terminals clean and secure can support reliable electrical performance.

Always disconnect the appropriate power source before inspecting or servicing electrical equipment. If you are unsure how to diagnose or replace an electrical component safely, consider consulting a qualified RV technician.

Keep Your RV Electrical Systems Working Reliably

RV relays and controllers may be small components, but they can have a major impact on the operation of important RV systems. From controlling electrical loads to coordinating more complex functions, these parts help keep motorhomes, campers, and travel trailers operating efficiently.

When replacing an RV relay or controller, accurate part identification and compatibility are essential. Checking part numbers, voltage requirements, terminal configurations, and equipment specifications can help you select the correct component.
