Step by Step Instructions on Determining the Generator Size for 50 Amp RV

Step #1: Consult the RV owner’s manual

The best way to size generator to run a 50 amp RV is to check the owner’s manual. You can find all you need to know about your camper through the manual, including the generator requirement.

With modern RVs, there is already a generator installed in the camper. But if you don’t have one, then you definitely need to buy a new generator.

Step #2: Understand the 50 amp RV service

In order to find the best generator for your camper, it’s ideal to understand the kind of service that a 50 amp RV provides. The fact is, this kind of RV offers 12,000W in total with its two hot wires of 120V. The 50 amp plug is commonly called a 120/240 split amp service.

This leads to a potential 12,000W generator for your RV. With this amount of power, you can have plenty of appliances running at the same time.

However, as tempting as it is to buy a 12000 watts 50 amp inverter generator for RV, it’s best not to.

This kind of generator is super expensive, which is not practical. Plus, the majority of RVers don’t use over 6000W of power, even while dry docking. The normal usage for a 50 amp camper is between 4000W and 6000W.

And you can prove this fact by actually finding the estimated power usage for all your appliances and fixtures.

Step #3: Check the appliances’ wattage

With a 50 amp RV, it’s safe to say that your camper is quite big. And so it follows that you have plenty of appliances, since you have more space for them.

What you need to do is make a list of all the electrical devices, equipment, and fixtures in your RV. And then consult the table below for the wattage of each appliance.

Step #4: Determine pattern of power usage

Though you have many appliances in your RV away from home, it’s not likely you utilize all of them at once. For example, when you are using the electric stove, you are probably not using the microwave or the dishwasher.

You need to focus on the appliances that you use simultaneously, such as the air conditioner, lights, refrigerator, and water heater. Once you figure out the normal pattern of power usage, you can find the perfect 50 amp RV generator to purchase.

Add the watts of all devices you use at the same time, and find a generator with a wattage close to the number you got.

Understanding the Generator Power Needs of Your RV

It’s imperative that you understand the kind of power your appliances need to function well.

Below is the table for the most common appliances in an RV. The data may not be 100% accurate, but they’re the normal wattages according to reliable sources. The important thing is, you have a baseline for your calculations for the generator size you need.

Appliances Watts Required
Air conditioner 1200W – 2400 W
Stove 900W – 2500W
Clothes iron 1000W – 1800W
Coffee maker 650W – 1750W
Dishwasher 1200W – 2400W
Hair dryer 1200W – 1875W
Washer 1000W – 1500W
Microwave 1000W – 1500W
Toaster 850W – 1200W
Blender 450W – 700W
Refrigerator 400W – 1200W
TV 43W – 600W
Radio 50W – 200W
Laptop 25W – 200W
Gaming console 70W – 180W
Light 60W – 75W
Electric grill 1600W – 1650W
Satellite receiver 240W – 250W

Another thing you need to understand is the startup power and running power requirements of your appliances. To have the right size generator, you need to consider the starting power the most. Keep that in mind as you find the power requirement for your RV.

Due to the bigger size of a generator for a 50 amp camper, the noise level can be high. However, most large-capacity generators utilize a quiet technology, so look for this feature when you search for a new generator to purchase.

Generators have different weights. Choose one that is less heavier than others, but of course, be wise and incorporate other factors into your decision.

Before you go charging alone to the nearest store selling RV generators, you need to understand that it’s better to come with a friend. A portable generator for 50 amp RV is anything but lightweight.
