Having an RV doesn’t mean you can hit the road without any planning. Some aspects are vital to know, especially if you are new to RVing. It doesn’t matter how you want to travel or camp power is one of the crucial aspects.
Your RV needs a fair amount of power to run efficiently and operate its important appliances to stay comfortable when camping. In this regard, if you have a 30 amp RV, you should know what size generator for 30 amp RV is good that you can have.
When at a campground or RV park, it is not always possible to plug your 30 amp RV into a stable and dependable power source. In such a situation, you’ll be required to get the right size generator for a 30 amp RV that can consistently supply power to all the RV appliances.
What Size Generator For 30 Amp RV?
Ideally, I recommend a 3,000W generator for 30 amp RV. Having a 3,000W generator for 30 amp RV means it will generate enough amount of power to efficiently run even the most power-hungry RV appliances such as air condition unit and microwave without any issue.
This is the question that needs an in-depth discussion, and that is why I’m here today. Below, I’ll discuss everything you want to know related to the 30 amp RV and 30 amp RV generators.
What Exactly 30 Amp Service is?
The electrical system of an RV is intended to let through the only electrical power, depending on the RV’s voltage and amperage. This is what makes 30 amp and 50 amp services a whole lot different. However, the focus here lies in the outlets of the electrical systems.
In my previous article that was about 30 amp and 50 amp services, I’ve mentioned that 30 amp RV service comes with three wires that include a neutral one, a ground wire, and a 120V wire, while on the other end, a 50 amp service comes with four wires that include a neutral wire, a ground wire, and two 120V wires.
You now may want to know how to express an ampere? Well, an ampere can be expressed as,
Amp = W/V (where Amp is Ampere, W is Watt, and V is Voltage)
Since both 30 amp and 50 amp services have both the amperage and voltage, it is easier for you to calculate their maximum Wattage by rearranging the above-stated formula.
For the 30 amp service, the maximum wattage would be 3,600W (120V x 30A = 3,600W).
While calculating the 50 amp Wattage, we have to multiply 12V by 2. Why? Because 50-amp service comes with two 120V wires. It is as simple as that.
Now, most people think that there is not much difference in amperage between 30 amp and 50 amp services, but the capabilities they tend to have is significantly different. In other words, 30 amp service performs 3x less than what 50 amp service is capable of.
That is why almost all the RVs that have fewer appliances and equipment come with a 30 amp service. However, if you need additional Wattages because you want to add more appliances in your RV, a 50 amp service is optional that you can have.
Moreover, if you think you don’t need additional Wattages and the existing power requirements are sufficient for all the appliances in your RV, you do not need to go with 50 amp since it will be nothing but a waste of your money that you will overspend.
What Size Generator for 30 Amp RV?
Generally, I recommend a 3,000W generator for 30-amp RV. Having a 3,000W generator for a 30-amp RV means it will generate enough amount of power to efficiently run even most power-hungry RV appliances such as air condition units and microwaves without any issue.
However, the maximum power that is required for a 30 amp RV is 3,600W. So, if you are dead serious about getting more than enough power for your 30 amp RV to turn all your RV appliances on simultaneously, you should go for a 3,000W portable generator.
Now that you know what size generator for 30 amp RV is ideal, you should also know how to choose the right size generator for a 30 amp RV. Most of the RVs come armed with a pre-installed generator underneath the compartment, but this isn’t always the same. You may also want to change your 30 amp RV generator or supplement the existing one.
So, how to choose the right size generator for a 30 amp RV?
Let’s discuss this matter in details;
How to Choose Right Size Generator for 30 Amp RV?
Here are some aspects that you may consider to get the right size generator for 30-amp RV.
1. Wattage of Generator
If you want to calculate the maximum Wattage for your 30 amp RV, it is simple math. You just have to multiply amp by the voltage to convert them into Watts.
30amp x 120 Volts= 3,600W
So, it is clear that a 30 amp RV can have a generator that generates up to 3,600W and not more than that. It also means if you’re going to buy a 5,000W generator for a 30 amp RV, it will be nothing but a waste of your hard-earned money since you’ll not be able to use those extra 1,400W.
However, all of that doesn’t mean you need to rush out to buy a 3,600W generator for your 30 amp RV since those 3,600W means they are the maximum that your RV needs. In certain cases, your RV might require fewer Watts. So, to determine how much Wattages your RV really needs, you have to break it according to the appliances.
This is also the point where you will need to differentiate between startup and running watts. By any chance, if you don’t know what startup and running watts mean,
- Startup Watts: The amount of power an appliance needs to get started.
- Running Watts: The amount of power an appliance requires to keep running smoothly.
Generally, Startup Watts is greater than Running Watts, making them essential when determining your RV need’s exact power.
If you add startup Watts for all the appliances, you will get the maximum power your RV needs at once. However, in reality, it is unlikely to happen, running all the appliances simultaneously.
The bottom line, you should buy a generator for a 30 amp RV that produces enough power to keep the most power-hungry appliance running efficiently.
2. Generator Noise Level
When buying a generator for a 30 amp RV, you should consider the generator’s noise level. After all, you don’t want a generator that keeps you awake all night when running. The normal sound level of humans is approximately 60 decibels.
For some of us, even a casual conversation can be disturbing when we are trying to sleep. It means you don’t really want to invest in a noisy generator that generates far greater noise than that. Luckily, you will find 30 amp RV generators that only produce 55 to 80 decibels when running.
Unfortunately, most of the 30 amp RV generators are not the most compact and lightest ones on the market. If you’re going to move the RV generator around, you don’t really want to break your back lifting a generator weighing up to 80 lbs – unless you are a professional weightlifter
When buying a 30-amp RV generator, look out for the ones with a collapsible handle and never-flat wheels.
4. Fuel Type
Most of the 30-amp RV generators require either gas, propane, or diesel to run themselves. If you have an RV with diesel fuel type, you may want to get your hands on the same fuel-type generator.
If you have a gas-powered RV, you may want to get the same fuel type generator since you can get the fuel anywhere you go. The same is applicable for propane fuel type generators and RVs. However, you may find it arduous to get propane in some places when the generator runs out of fuel.
Furthermore, you may want to buy a generator with a dual-fuel type. These generators are convenient since you can easily switch to other fuel types when one runs out. But, you should also know that dual fuel type generators are also more expensive than single fuel type generators.
5. Economy Mode
30 amp RV generators that come equipped with economy mode are great to have since they seriously impact on your machine functionality. Having this mode means the generator will be able to smartly control the fuel consumption by determining how much power an appliance need at a time and when to slow the engine down.
Moreover, when the engine’s electrical load reduces, it automatically puts the engine to idles lower, which allows the machine to run efficiently and quietly. Furthermore, this also extends the engine lifespan and delivers higher fuel efficiency.
6. Fuel Efficiency
Having a portable 30 amp RV generator with an economy mode feature means you can save a serious amount of money that otherwise you have to spend on fuel. You should consider having a 30 amp RV generator that gives you an impressive run time with a single fuel tank.
7. Generator Cover
Don’t waste your time looking to have a 30 amp RV generator with a cover, as there is no on the market. Also, it is not a feature but an accessory that you have to buy separately if you want. Although buying a generator cover is not mandatory, I suggest you buy one if you are going to place it outside. This will protect your 30 amp RV generator even if you treat it rough to extend its life a bit more.
8. Parallel Capability
Even though it is more unlikely to happen with a 30 amp RV, but still if you want to increase Wattage for your RV appliances to run them all at once, you should buy another generator that produces the same Wattage to double the power.
For example, if you already have a 2,000W generator, but you need additional Watts to run your RV air conditioning unit, you don’t have to go out and spend $1,000, as it is better to spend half of that to get yourself another generator.
However, in such a scenario, you will still have to buy an inverter generator parallel kit.
So, what are the best 30-amp generators?
