Consider this scenario, imagine working on a crucial project, enjoying your favorite TV show, making your favorite coffee with a coffee maker, drying your clothes with a cloth dryer, using a dishwasher to wash dishes, and taking advantage of the summer’s heat because you have a cooling system or the winter’s cold because you have a warming system, making your favorite meal, and then suddenly experiencing a power outage.

A power outage is an unanticipated set of events that can disrupt your life. A house generator is a crucial solution for this situation, especially during an extended power outage.

Finding a generator that can effectively power all your appliances and equipment is essential. Generators are available in different sizes. It is vital to choose the right generator size for your house. A generator that is too small for your needs won’t be able to power your equipment, while one that is too large will cost you money.

This blog post will answer questions like why proper generator sizing matters and what generator factors you should consider. And how to calculate your power requirements.


Generator Wattage Calculator

This generator calculator is intended to provide a reliable foundation to estimate your backup power needs. This will help answer the question What size generator do I need? and What size generator do I need for my house chart

Our calculator includes the square footage of your residence. Before calculating the total wattage:

  1. Make a list of the things that require the generator’s electricity.
  2. Write down the corresponding objects’ start and running wattage.



What You Need to Know About Generator Sizing

Size counts when it comes to generators. Choosing the right generator size is essential since an insufficient voltage generator could overload if it powers too many appliances, leading to equipment damage. Typically, A generator that is too small for your needs won’t be able to power your equipment, while one that is too large will cost you money. So, what is the perfect size to cater to your needs? Or what size generator do I need? Let’s start with the basics.

Ensure the generator you purchase has enough power to run your essential appliances efficiently. Typically, the power output of a generator is measured in Watts (W) or KiloWatts (kW). There are two outputs of a generator starting and running output/wattage. Knowing the proper starting and running wattage for the generator to power your devices efficiently is essential. These can be found in the manual with the equipment or on the manufacturer’s plate.

For instance, a typical Washing Machine starts up consuming 2250 watts of power but only consumes 1150 watts of power while it is operating.

Here are some advantages of choosing the right size generator:

  • No unplanned system failures,
  • Longer system life
  • Increased generator lifespan
  • Lowered risk of asset damage
  • No capacity overload shutdowns.
  • Safety


Making Your Power Go Further – Expert Tip from AAGENPRO.COM

Suppose you want to use the generator as your primary source of electricity, size it to operate at 70–80% of its maximum capacity. The performance will be improved, and future power needs can be accommodated by leaving a 20–30% safety margin.

Remember that you don’t have to operate all your equipment and appliances simultaneously. Turn off other devices when you are not using them to cater to appliances you need to use. For example, Use the washing machine only when you need to do laundry and turn it off when you do not want to do laundry.

Watts vs Amps

Various units called watts (W), and amps (A) are used when calculating power. The power the load will consume to provide a useful functioning output is measured in watts. The amount of power the load will consume to provide a useful functioning output is measured in amps. The following calculation formula makes it simple to convert an item’s listed power in watts to amps; watts divided by Volts equals Amps::

Amps = Watts ÷ Volts

and the following calculation formula makes it simple to convert an item’s listed power in watts to amps is Amps multiplied by Volts equals Watts:

Watts = Amps x Volts

The voltage will typically be 120V for most devices, but some run at a higher volt.

For example, Identifying the amps of a 25000w generator with a 120-volt will be,

Amps= 25,000 ÷ 120

Amps= 208.33A

and identifying the watts of a 208.33A generator with a 120-volt will be,

Watts= 25,000 x 120

Watts= 25000w

Resistive vs Reactive Loads

You can power many electrical equipments with your generator, but they generally fall into reactive or resistive equipment.

Resistive loads are devices that require a steady stream of electricity from the generator—for example, incandescent lamps and electric heaters.

Reactive loads are devices that use the generator to draw a fluctuating amount of power. Examples include a washing machine, refrigerator, and Fans.

Washing machines, refrigerators, Fans, and other appliances with electric motors require additional power to start up. These appliances are known as reactive loads because of the motors inside them.

Most loads are neither exclusively resistive, exclusively reactive, or exclusively inductive. Numerous real-world loads employ varied combinations of both.

Be Smart When Starting Appliances – Expert Tip from AAGENPRO.COM

We’ll assume, for the time being, that you’ll turn on the appliance with the lowest starting wattage first and then the highest starting wattage last. This leads to a lower maximum draw on the generator than starting them simultaneously.

Assume you wish to use a Heat Pump, Electric Stove, and freezer. The Heat pump has a starting wattage of 4500w, the Electric stove has a starting wattage of 2100w, and the freezer has a starting wattage of 1200w.

You might believe you require a generator with a maximum rating of more than 7,800 watts if you total up the starting watts. And this is the case only if you start all three appliances simultaneously.

Once the freezer is operating, the electric stove can be turned on. The generator’s maximum draw will be 2,300 watts at this time (200 running watts for the freezer plus 2100 starting watts for the electric stove).

The Heat pump can be added once the electric stove has declined its operating wattage.

The maximum demand is 6,800 watts because you need to add the starting watts for the heat pump with 2300 watts (the total operating watts for the freezer and electric stove).

Even more power savings are possible by:

Turn off other appliances and gadgets when using devices with high starting wattages. For example, Use the washing machine only when you need to do laundry and turn it off when you do not want to do laundry.

Can Cumming Generator Power a Whole House?

The size of your home will determine this.

Finding a smaller generator or a portable power station powerful enough to run every appliance and electrical equipment is essential, but power and cost must be considered. Generally, high-power generators are substantially much more expensive than lower-power ones, but it doesn’t stop you from buying a reliable generator for your home.

Having a reliable home generator to power your home is ideal. You should be able to power your lights, refrigerator, television, Desktop Computer and Monitor, and other appliances with a 5,000–7,000-watt generator. If you want to operate additional power-hungry equipment, such as an Electric Water Heater or Clothes Dryer, a 10,000-watt unit is necessary.

You can rely on a smooth energy transmission when you choose a high-quality item like a Cummins home standby generator.

The Best Generator for Sensitive Electronics

The electricity produced by conventional generators is High-frequency distortion caused by the generator’s erratic output of voltage and frequency. This behavior can damage sensitive electronics such as laptops and mobile phones.

Although inverter generators also utilize gasoline or propane as fuel, they function mechanically in different ways. The high-frequency AC from the engine is transformed into DC by an alternator. This is then changed back to AC by the inverter. As a result, making it a better option for powering delicate electronics.
