How to Choose 50-Amp RV Generators

Choosing the right 50-amp generator, however, involves more than just picking the most powerful unit. It requires a careful consideration of various factors to ensure it perfectly matches your specific RV lifestyle, power needs, and budget. This guide will walk you through the essential criteria to help you make an informed decision and invest in the best 50-amp RV generator for your adventures.

Understanding Your Power Requirements

The first and most critical step in choosing an RV generator is accurately assessing your power needs. A 50-amp service indicates a robust electrical system, capable of handling significant loads. To determine the exact wattage you require, list all the appliances you plan to run simultaneously. Pay particular attention to “starting watts” (surge watts) for appliances with motors, such as air conditioners, refrigerators, and microwaves, as these require a brief burst of extra power to kick on.

These surge watts can be significantly higher than their continuous “running watts.” Sum up the running watts of all appliances you anticipate using at once, then identify the highest starting wattage among your motor-driven appliances. Your generator’s surge rating should comfortably cover this peak starting requirement, and its running watts should exceed your total continuous draw. Most 50-amp RVs will comfortably operate with a generator offering between 9,000 to 12,500 running watts, ensuring ample power reserves for various scenarios.

Fuel Type: Flexibility for Your Journey

Modern RV generators come in several fuel configurations, each with distinct advantages. Your choice of fuel type can significantly impact convenience, cost, and environmental footprint.

Gasoline Generators

Gasoline is the most common and readily available fuel. These generators are typically powerful and can be found at various price points. However, gasoline has a relatively short shelf life, requires careful storage, and produces more emissions than other fuel types. Its availability, especially at remote gas stations, is often a key factor for many RVers.

Propane (LPG) Generators

These generators offer a cleaner burn, longer storage life, and typically produce fewer emissions than gasoline. Propane tanks are often built into RVs, making them a convenient, pre-existing fuel source. While generally more expensive per gallon than gasoline, propane’s efficiency and clean-burning nature can offset some costs. Availability can be a concern in very remote areas, but it’s widely accessible across most of the country.

Dual Fuel Generators

Dual-fuel generators are increasingly popular for RVers because they offer the best of both worlds, allowing you to switch between gasoline and propane. This versatility is invaluable when one fuel source is scarce or when you want to leverage propane’s clean-burning benefits. Having multiple fuel options enhances preparedness and extends your total run time when away from refueling stations.

Tri-Fuel Generators

Tri-fuel generators take versatility a step further by adding natural gas capability to gasoline and propane. While natural gas isn’t typically practical for mobile RV use (as it requires a connection to a residential line), this option is fantastic for home backup scenarios where a natural gas line is accessible. For RVers, the primary benefit remains the dual-fuel flexibility, with the tri-fuel option serving as a bonus for stationary use.

Generator Type: Conventional, Inverter, or Open Frame

The type of generator determines its performance characteristics, particularly noise levels and power quality.

Conventional Generators

These are robust, workhorse generators known for their high power output. However, they are typically the loudest, which can be an issue in campgrounds or quiet natural settings. They also produce “dirty” power with higher Total Harmonic Distortion (THD), making them less suitable for sensitive electronics without a surge protector.

Inverter Generators

Inverter generators are prized for their quiet operation and “clean” power (low THD, typically under 3%). This makes them ideal for sensitive electronics like laptops, smart TVs, and medical devices, which are common in modern RVs. They are also more fuel-efficient, as their engines can adjust speed to match the load. While often more expensive and sometimes less powerful than conventional generators of the same class, high-wattage inverter generators suitable for 50-amp RVs are now readily available and are often the preferred choice for RVers who value peace and quiet.

Open Frame Inverter Generators

An emerging category, open-frame inverter generators bridge the gap between conventional and fully enclosed inverter models. They offer the clean power and fuel efficiency of inverter technology but in a more open, often lighter, and sometimes slightly louder, frame than traditional enclosed inverters. They can still be quieter than conventional generators but might not reach the whisper-quiet levels of premium enclosed inverter units. For 50-amp RVs, these offer a powerful, clean, and often more cost-effective inverter solution.

Noise Levels

Noise is a significant consideration, especially for RVers who spend time in campgrounds or serene natural environments. Generator noise is measured in decibels (dB). For comparison, a normal conversation is around 60 dB. Many campgrounds have noise restrictions, particularly at night. Inverter generators are generally the quietest, often operating in the 50-65 dB range. Conventional generators, especially high-output 50-amp models, can easily exceed 70-80 dB, which can be disruptive to neighbors and your own peace. Look for generators with “Quiet Technology” or enclosed designs if noise is a priority.

Starting Mechanism

Ease of starting can make a big difference, especially on cold mornings.

Recoil Start

This is the traditional pull-cord start. It’s simple but can be physically demanding, especially for larger engines.

Electric Start

Most 50-amp generators feature an electric start, which means turning a key or pushing a button to fire up the engine. This is a highly convenient feature.

Remote Electric Start

For ultimate convenience, some generators include a remote key fob that allows you to start and stop the unit from a distance. This is perfect for when you want to power up your RV from inside without stepping out.

Portability and Size

While a 50-amp generator will always be a substantial piece of equipment, portability still matters. Consider its physical dimensions, weight, and whether it has a built-in wheel kit and handles. If you plan to move it frequently, a robust wheel kit and ergonomic handles are essential. Even if it’s primarily for stationary use, you’ll still need to transport it to and from your RV.

Safety Features

Modern generators come equipped with crucial safety features:

Carbon Monoxide (CO) Sensor

An absolute must-have. This sensor detects dangerous levels of CO gas and automatically shuts down the generator, protecting you and your family from harmful fumes. Many reputable brands now include this as a standard feature.

Automatic Low Oil Shutdown

This feature protects the engine from damage by automatically turning off the generator if the oil level drops too low.

Overload Protection

This prevents damage to the generator and your appliances by automatically shutting off power if the load exceeds the generator’s capacity.

GFCI Outlets

Ground Fault Circuit Interrupter outlets offer protection against electric shock, particularly important in outdoor or damp environments.

Outlets and Connectivity

For a 50-amp RV, ensuring the generator has the correct outlet is critical. Look for a NEMA 14-50R outlet, which is the standard 50-amp RV receptacle. Additionally, check for other useful outlets like 30-amp twist-lock (L14-30R or L5-30R), 20-amp household outlets (5-20R), and even USB ports for charging smaller devices. If you plan to use the generator for home backup, ensuring it’s “transfer switch ready” is also a valuable feature.

Run Time and Fuel Efficiency

The fuel tank size and engine efficiency determine how long a generator can run on a single tank of fuel at a given load. A longer run time means less frequent refueling, which is especially beneficial when boondocking. Inverter generators typically offer better fuel efficiency due to their ability to vary engine speed.

Brand Reputation and Warranty

Choose a generator from a reputable brand known for quality and customer service. A strong warranty (typically 2-3 years) provides peace of mind and protection for your investment. Read reviews and consider the availability of replacement parts and service centers.

Conclusion

Selecting the best 50-amp RV generator involves balancing power output, fuel efficiency, noise levels, safety features, and budget. By carefully evaluating your specific needs against the various options available, you can confidently choose a generator that will provide reliable power for all your RV adventures, ensuring comfort and convenience wherever the road takes you. Invest wisely, and your RV experience will be truly boundless.
