How to Choose Inverter Generators For RV

Choosing the best inverter generator for your RV is a critical decision that directly impacts your comfort, convenience, and ability to enjoy off-grid adventures. With a myriad of options available, understanding the key factors involved will help you make an informed choice that perfectly matches your RV lifestyle. From power requirements to fuel types and advanced safety features, here’s a comprehensive guide to navigating the selection process.

Understanding Your Power Needs

The first and most crucial step in selecting an RV inverter generator is to accurately assess your power requirements. This involves identifying all the appliances and devices you plan to run simultaneously. RVs typically have varying electrical needs, ranging from basic lighting and charging to powering air conditioners, microwaves, and entertainment systems.

Calculating Wattage

To determine the total wattage you’ll need, list all the appliances you intend to use at the same time. Check their labels for “starting watts” (also known as surge watts) and “running watts.” Starting watts are the brief burst of power an appliance needs to kick on, especially those with motors like air conditioners, refrigerators, and microwaves. Running watts are the continuous power required to keep them operating. Always prioritize the highest starting wattage among your simultaneously used appliances, then add the running watts of all other devices. Your generator’s surge watts must be able to handle this highest starting load, and its running watts must exceed the sum of all running loads.

For example, an RV air conditioner might require 2000-3000 starting watts but only 1500-2000 running watts. If you also want to run a microwave (1000 running watts, 1500 starting watts) and charge a laptop (50 watts running) at the same time, you’d need a generator with surge capacity to handle the AC’s starting load, plus enough running watts for the AC, microwave, and laptop combined.

Fuel Type Considerations

Inverter generators primarily run on gasoline, but many modern units offer dual-fuel capabilities, allowing them to operate on both gasoline and propane. Each fuel type has its advantages and disadvantages.

Gasoline Generators

Gasoline is widely available, making it easy to refuel on the go. Gasoline generators often provide slightly higher power output compared to their propane counterparts. However, gasoline has a shorter shelf life and can become stale, potentially causing carburetor issues if not properly stored or treated with stabilizers. It also has a distinct odor and is highly flammable, requiring careful handling and storage.

Propane (LPG) Generators

Propane offers a cleaner burn, leading to less engine maintenance and fewer emissions. It has an indefinite shelf life and is safer to store than gasoline, as it’s kept in sealed tanks. RVs often come equipped with propane tanks for heating and cooking, making it a convenient shared fuel source. The downsides are that propane typically yields slightly less power output and is generally less fuel-efficient, meaning shorter run times per tank compared to gasoline. However, propane generators are often easier to start in cold weather.

Dual-Fuel Generators

Dual-fuel generators offer the best of both worlds, providing flexibility to switch between gasoline and propane based on availability, cost, or convenience. This versatility can be invaluable for extended trips or in remote locations where one fuel type might be scarce.

Noise Level: Quiet Operation is Key

One of the most significant advantages of inverter generators for RV use is their quiet operation. Unlike conventional generators, inverters typically operate at much lower decibel levels, often ranging from 50 to 65 dBA. This is crucial for maintaining peace in campgrounds, adhering to noise ordinances, and simply enjoying a serene outdoor environment.

Look for generators with an “Eco Mode” or “Economy Mode,” which automatically adjusts the engine speed to match the load, further reducing noise and improving fuel efficiency. A lower decibel rating, especially at a quarter or half load, will make a big difference in your camping experience and relationships with fellow campers.

Portability and Design

An RV inverter generator needs to be portable enough to load, unload, and move around your campsite. Consider the weight and physical dimensions of the unit. Many models feature built-in wheels, telescoping handles, or sturdy carry handles to facilitate transport. Lighter units (under 60 pounds) are ideal for easier handling, while heavier, higher-wattage models may require wheels or two people to move.

Also, evaluate the overall design: is it compact enough to fit in your RV’s storage compartments or truck bed? Does it have a robust frame that can withstand the rigors of travel and outdoor use?

Output and Safety Features

Beyond basic power output, modern inverter generators come with a host of features that enhance functionality, safety, and convenience.

Clean Power Output (Low THD)

Inverter generators produce “clean power” with a low Total Harmonic Distortion (THD), typically less than 3%. This is crucial for safely operating sensitive electronics such as laptops, smartphones, TVs, and medical equipment, preventing damage that can occur with the “dirty power” from conventional generators.

RV-Ready Outlets

For RV use, look for a generator equipped with a 30-amp RV receptacle (TT-30R). This allows for direct plug-and-play with your RV’s shore power cord, eliminating the need for adapters. Additional outlets like 120V household receptacles, 12V DC ports, and USB charging ports increase versatility.

Safety Protocols

• Low Oil Shutdown: Automatically shuts off the engine if oil levels are too low, preventing costly damage.
• Overload Protection: Prevents damage to the generator and connected appliances by shutting down if the load exceeds capacity.
• CO Sensor (Carbon Monoxide Shutdown): A vital safety feature that automatically turns off the generator if dangerous levels of carbon monoxide are detected, protecting users from this odorless, colorless gas.

Parallel Capability

Many inverter generators are “parallel capable,” meaning you can connect two identical units together to effectively double your power output. This is an excellent feature if you sometimes need more power (e.g., to run two ACs) but prefer the flexibility and portability of two smaller, lighter units for everyday use.

Electric/Remote Start

While recoil (pull) start is standard, many advanced models offer electric push-button start for effortless ignition. Some even include remote start with a key fob, allowing you to power up or shut down the generator from inside your RV, which is a significant convenience, especially in inclement weather.

Brand Reputation and Warranty

Invest in a generator from a reputable brand known for quality and customer service. Brands like Honda, Yamaha, Generac, Champion, WEN, and Westinghouse are popular choices in the RV community. Check the warranty period and what it covers, as well as the availability of parts and service centers.

Budget Considerations

Inverter generators generally cost more than conventional models, but the benefits of quiet operation, fuel efficiency, and clean power often justify the investment. Set a realistic budget based on your power needs and desired features. Remember that the cheapest option isn’t always the best value in the long run.

Conclusion

Choosing the best inverter generator for your RV involves a careful evaluation of your specific power needs, preferred fuel type, desired noise level, and essential features. By prioritizing clean power, portability, quiet operation, and key safety protocols, you can find a reliable and efficient power source that enhances your RV experience, allowing you to enjoy all the comforts of home wherever your adventures take you. Happy travels!
