What Can a 15000-Watt Generator Run?

What Is a 15000W Generator?

A 15,000-watt generator is a reliable solution for those living off the grid. It can charge multiple devices like large home appliances, power tools, and other off-grid appliances. If you're planning to invest in a 15,000-watt generator, the first step is to understand what appliances you want to run and whether the generator can handle them.

Here are the different types of 15000-watt generators available:

15000 Watt Portable Generator: As the name defines, 15000-watt portable generators are lightweight and can be carried anywhere. While they are not small in size, they feature handles and wheels for easy movement.

15000 Watt Inverter Generator: They are quieter, fuel efficient, and safer solutions for charging sensitive electronics like phones or laptops. Many larger 15000-watt inverter generators can charge an entire home.

15000 Watt Solar Generator: These generators are quiet, reliable, and emission-free solutions to power various appliances at home or while enjoying outdoor excursions. Jackery Solar Generators are available in a variety of capacities as well as sizes to meet the needs of most use cases.

Before you power appliances with a 15000-watt generator, you'll need to check out the following terms:

Starting Watts: It is the amount of additional power an appliance draws when starting up and is also sometimes called surge watts.

Running Watts: Also called rated watts, it is the number of watts any appliance draws continuously when in use. Running watts are generally as important as starting watts, but you'll find them lower than the starting watts.

Surge Wattage: It is the maximum wattage a generator can deliver for a short time to power motorized-based appliances. The surge wattage of the popular Jackery Solar Generator is typically double its rated wattage.

Watt-Hour: It is the unit of energy that equals one watt of power used in one hour. The higher the Wh of the battery, the more appliances it can run for a long time.

What Size Generator Do I Need?

If you're wondering what size generator I need to charge home or outdoor appliances, here's a step-by-step process you'll need to follow.

Step 1: Start calculating the right generator size by listing the appliances you want to power "simultaneously." Check the running and starting wattage of each appliance you listed and note them down. If you cannot find the wattage on the appliance, use the formula:

Watts = Amps × Volts

Step 2: Add the running wattage of all the listed appliances to find the total running watt required. Similarly, find the appliance with the highest starting watts.

Step 3: Add the total running watts and the highest starting watts together. This number represents the surge wattage that the generator should supply.

What Can a 15000 Watt Generator Run?

A 15,000-watt generator can run various appliances, including large refrigerators, ACs, electric clothes dryers, washing machines, hair dryers, curling irons, microwave ovens, etc. While choosing what you can run on a 15000W generator, you'll need to focus on running and starting wattage. The following sections show what appliances you can run with a large 15000-watt generator at home, work site, RV, and off-grid living.

Will a 15000-watt Generator Run a House?

Yes. A 15000 running-watt generator is enough to run most standard home appliances, drawing anywhere between 100 - 2000W per hour. It can also charge power-hungry appliances like electric water heaters, central air conditioners, dryers, etc. With a 15000-watt home generator, it is possible to keep most medium to large appliances — and even run two or three simultaneously.

Work Site

Many builders and contractors typically need a larger generator of at least 15000 watts to power many electric tools. The best 15000-watt generator can supply electricity to circular saws, table saws, portable air compressors, bench grinders, chain saws, electric leaf blowers, etc. If you want to run multiple portable electric tools at the same time, make sure you do not run up against the generator's surge power limitations.

RV

A 15,000-watt generator is enough to charge small and large RV appliances. It offers enough energy to power the kitchen appliances, air conditioning unit, space heater, and lights. However, if you're planning to go for the best 15,000-watt dual-fuel generator for your RV, you'll need to pay attention to the space. A larger generator might take up a lot of space in an RV, making it hard to live comfortably. That's why opting for a small RV generator that fits the space and power needs is best.

Off-Grid Living

A 15000-watt generator can charge many off-grid appliances, including power-hungry electric stoves, central air conditioners, space heaters, sump pumps, well pumps, etc. Since these appliances use a lot of power, ensuring the total running and surge watts do not exceed the generator's power capacity is essential.
