30 Amp Generators: Best Picks, How to Choose, and More

What Is A 30 Amp Generator

Whether planning for full-time RV living or going for a short camping trip, you'll need to pack a backup power source. With a 30-amp generator, you can power all your essential appliances, even when you're off the grid.

No matter if you're using a refrigerator, electric grill, or laptop, an RV battery backup source can keep you comfortable and connected regardless of where you are. But not all 30-amp solar generators are created equal. Some generators are too loud, while others don't have enough power.

If you want a large battery capacity power solution that emits little to no noise, consider Jackery solar generators for RVs. These solar solutions are specially built with industry-grade materials to charge most outdoor devices for long hours. In this Jackery article, we will dive deep into what size solar generator will meet your RV power requirements and some best 30 amp generators.

What Size Generator Do I Need For My 30 Amp RV?

Typically small to medium-sized motor homes, campers, and RVs have a 30-amp electrical system. This means you'll need a 30-amp generator to fulfill the electrical requirements of all appliances in the RV.

The simple formula to determine the maximum power that a 30 amp RV is volts × amps. Since the 30 amp electrical system uses 120V, you can calculate the maximum power by multiplying the two values.

Maximum Power from 30 Amp RV Plug = 120V × 30A = 3600W.

However, this doesn't mean you need a 3600-watt generator to run appliances. Since you'll be using only a few devices simultaneously, a 3000-watt generator can efficiently power most RV devices.

One such powerful and robust 30-amp power solution is Jackery Solar Generator 2000 Pro. It can keep your appliances powered during your travels. Its 2160Wh battery capacity and 2000W power output can seamlessly charge 99% of your electrical appliances.

How Many Watts Does A 30 Amp RV Use?

When connected to a 120-volt power source, a 30-amp RV can use up to 3600 watts. This is because a 30 amp plug has one 120-volt hot wire, unlike a 50 amp plug which has two.

The formula to determine the watt requirement in a 30 amp generator is multiplying amps by volts.

Watt Requirement = 30 amps × 120 volts = 3600 watts.

How Much Electricity Needs For My 30 Amp RV?

The simple way to understand the right size of solar generator for your RV trailer is by determining your electrical needs.

A few things you'll need to calculate before choosing the generator include:

How many appliances are you planning to use at one time?

What are the starting and running watts of your RV appliances?

What are the power needs of all your RV appliances?

The more RV appliances you use at a single time, the larger the battery of your generator should be. The reason is that only a large generator can support multiple high-power-consuming appliances, like ACs, refrigerators, etc., in your RV.

Another factor that determines the generator size is the running and starting watts of the devices. For instance, an RV refrigerator consumes 180 running wattage, while you need to supply 600 watts to start the appliance.

Similarly, other high-power-consuming appliances like electric grills, microwave ovens, blenders, RV AC, etc., require more starting wattage than running. Below we will reveal some most common RV appliances with their starting and running watts.


Starting Watts

Running Watts

RV Fridge



Coffee Maker



Electric Grill






Laptop Computer



Small Flat TV



Portable Fan



Hair Dryer






It is evident from the table that appliances draw more power when they start. Therefore, the right size of solar generator should be capable of providing starting wattage to all devices for efficient functioning.

A 30-amp generator is suitable for charging all the appliances in your RV. For example, suppose you are using an RV AC that consumes nearly 700 to 1500 watts of power, a refrigerator consuming 300-400 watts, and a few lights.

In this case, the total power consumption will be 700W + 300W + 60W = 1060W.

A 2500-2800 watt solar generator will be sufficient to run these appliances for a few hours in a 30 amp RV. However, if you want to power RV electrical devices for a long time, a 3000-watt solar generator or higher is suitable for your needs.

Best 30 Amp Generators

While it might be tempting to use a gas generator while RVing as they are cheaper, it is not highly recommended. This is because an RV is a closed space that requires a clean and quiet power source. You'll need to choose the right-size solar generator that can seamlessly supply power to all your desired RV and camping appliances.

Jackery is one of the leading solar brand manufacturers that build high-quality solar panels, power stations, and solar generators.
