What Can You Run On a 7500 Watt Generator

When buying a generator, it’s crucial to think about what power requirements your devices have. For example, if you need an air conditioner running during a heatwave, then you’ll want something that has more watts than someone who needs lighting and some outlets for their phone charger. So, what can you run on a 7500 watt generator.

A 7500 watt generator is an excellent option for people who need to run powerful equipment without access to the grid. It is a perfect size for a home power backup solution. With its power output (7500 watts), you can power a wide range of appliances, including a water heater, refrigerator, well pump, AC unit, among others. This blog post will get into details about what you can run on a 7500 watt generator.

How to Determine Your Energy Load?

A 7500 watts generator is a perfect choice for cushioning you from the frustrations that come with power outages. It can power a variety of household appliances, construction equipment, power tools, and an RV. To determine whether this generator can handle your power demands, you need to calculate your energy load.

Here is a quick way to determine your energy load:

  • Take an inventory list of all appliances and equipment in your home, workplace, or RV. Check out each appliance’s wattages by checking their respective power label (the fine print found near the item’s plug) or checking on their manuals. You may also consult a professional electrician to establish the wattages for you.

Determining your total wattage demand will help you know what you can run on your 7500 watt generator and help you not to overload it. Overloading a generator can lead to overheating and wearing out of the engine; this will shorten the generator’s life. Other risks involved with overloading a generator include:

  • Damaging your home’s wiring system
  • Inadequate power supply to your power equipment
  • It can destroy your power equipment.
  • Electrical hazards such as fire, electrocution, or death from equipment malfunctioning

You must avoid overloading your generator. When determining your power load, you must take into account your appliances’ starting and running wattage. Failure to differentiate the two types of wattages may lead you to buy the wrong size of a generator.

So, what is starting and running wattage?

  • Starting watts: Also referred to as the surge watts or peak wattage, is the wattage required by a device to start up. However, not all devices have starting watts; it is only reserved for devices with an electric motor, e.g. refrigerator, power tools, blender, among others. So, starting power of wattage is the amount of power required to start the electric motor of power equipment. Typically, the starting watts is only required during the first three to five seconds of starting a device with a motor component in it.
  • Running watts: The running wattage is the continuous power or rated watts an electrical appliance requires to run after starting. It is also called the continuous draw, and it is the wattage power equipment operates at when in use. Running watts are lower than starting watts.

When considering the total power load for electrical equipment, you must consider the starting power. A device may require high wattage to start but, once it is running, then the power requirement decreases.

So, when calculating the total power load that you can power concurrently with your 7500 watt generator, add all the starting wattages. The results will be the total watts required to start and run such items.

Powering a Home with a 7,500 Watt Generator

What Can You Run On a 7500 Watt GeneratorMost homeowners look for generators that can power their essential household appliances during an emergency. Among the essential appliances, there are power-hungry appliances and some which are low consumers. Heavy-duty household appliances are refrigerators/freezers, water heaters, heating, and cooling systems. Powering such appliances concurrently can consume more power than running them separately. Appliances such as TVs, PCs, toasters, and light bulbs are low-energy consumers.

In a home set-up, a 7,500 watt generator can run:

A normal fridge has a starting watt of 800 to 1200W and a running wattage of about 150W. The high starting wattage is due to the compressor, which may require more than one second to power up and run efficiently.

  • A water heater that has 120 volts element consumes about 1125 watts, while a 240 volts element consumes 4500 watts.
  • Air-condition units 7,000 BTU (Starting watts 2200W and 1000 running watts) to 10,000 BTU (5000 starting watts and 1500 running watts).
  • A 1/3HP well pump may have 1400-3000 starting watts and 750 running watts.
  • An average washing machine has 1400 surge watts and 500 starting wattage.
  • A coffee maker 600 to 800 watts depending on model
  • An average microwave 800 watts

To determine whether you can power your appliances concurrently, add the wattage of your appliances. If you get this number to be more than 7000 watts, then it is wise to power them separately or purchase a more significant generator.

This becomes necessary if some household appliances are high-consumers and others low-consumers. For instance, a water heater, lights, TV and refrigerator can run simultaneously with no issues but not the two air-conditioners because of their high wattage consumption.

With careful consideration of your household appliances, a 7,500 watt generator can power your house as if there was no blackout, only that you will be limited on running heavy-duty appliances concurrently.

Powering a Job Site with a 7,500 Watt Generator
