How Many Watts Does a 50 Amp RV Use?

The wattage of a 50-amp RV will depend on the appliances you are using in your mobile vehicle. A 50 amp plug has two 120-volt hot wires, which means it can provide more watts of power than a 30 amp plug.

Each hot wire in 30 amps or 50 amps plug is 120 volts. When we multiply 50 amps by 120 volts, we get a rating of 6000 watts. Since the 50 amp connection has two hot wires, the maximum rating becomes 12,000 watts. In short, a 50-amp RV uses nearly 12,000 watts of power.

However, you don't always need a solar generator that can provide that 12kWh power to efficiently run appliances in a 50 amp RV. The exact amount of wattage you need will depend on the electric needs of the devices you are using and how many of them are working at the same time.

To determine the wattage required, you can multiply the amps by the volts. For example, if you are using an air conditioner that draws 15 amps and a refrigerator that draws 5 amps, the total wattage required would be 15 amps * 120 volts + 5 amps * 120 volts = 1800 watts + 600 watts = 2400 watts.

Similar to the above example, you can determine how much electricity you are planning to use in your RV by adding the wattage of all appliances. If all your RV devices use 4000 watts combined, you can choose a solar generator that supplies 4000 watts or more power.

How Much Electricity Needs for My 50 Amp RV?

The electricity needs of your 50-amp RV will depend on the starting and running watts of all the RV appliances. Startup or starting watts refers to the power a device requires to get started while running watts means the energy needed to keep the appliance running for hours.

While choosing the best solar generator for your RV, you need to ensure that it can supply enough startup wattage for your appliances. This is because some devices, such as ACs and microwaves, require a lot of power to start up.

In the below table, we will include some common RV appliances with their starting and running wattage.


Starting Wattage

Running Wattage

Microwave oven



Electric grill



RV refrigerator



Coffee maker












Note: These are the general numbers to give you an idea of how much electricity your appliances consume. If you want to find the exact wattage requirements of the devices, you can check the user's manual.

To calculate the basic wattage needed for an RV, you will need to add up the running watts you are planning to use simultaneously. For example, if you use an RV AC (1200 watts), a portable refrigerator (200 watts), and lights (60 watts), the total basic wattage you'll require will be 1200 + 200 + 60 = 1460 watts. In this case, you will need a solar generator that efficiently supplies 1500 watts or more electricity to all the appliances.

It is also essential to consider the peak wattage of your RV devices when choosing a 50-amp inverter. Peak wattage is the maximum amount of power an appliance can draw at any time. For example, an air conditioner may have a running wattage of 500 watts, but its peak wattage might be 1500 watts.

If you plan to use multiple appliances at the same time, you will need to make sure that your 50-amp portable generator can handle the peak wattage of all of the devices.
