Benefits of choosing the right size generator

Reliable power: Right size generator will provide a reliable supply of power that meets your specific needs. To ensures all of your home's essential devices and appliances will function smoothly, keeping you comfortable and safe during power outage.

Economically efficient: Opting for generator that fits your power needs will prevent unnecessaryinitial costs and continual operational costs tied to larger models. It represents a sensible investmentthat will meet your power requirements without overstretching your finances.

Prevent hardware damage: Employing a generator that meets your exact power requirements safe guards against potential harm from excessive or insufficient load. As a result, generator and devices it powers are less prone to suffer damage, leading to an extended service life and areduction in repair expenses.

Generator size-rated wattage and running wattage

The essence of generator sizing comes down to identifying its rated and running wattage (wattage).

Rated wattage

The rated wattage of generator refers to its peak output potential, typically quantified in watts or kilowatts. This figure indicates the highest power level that the generator is capable of supplying at any single moment. This is critical to ensuring your generator can handle the peak power demands of all connected appliances and devices without overloading.

Running wattage

This refers to the actual wattage that the generator produces under normal operating conditions. It's crucial to align this with average combined wattage of appliances and electronics that you need to energize. Running wattage must take into account the continuous and surge (starting) wattage of the equipment to prevent overloading the generator when demand suddenly increases.

Essentially, understanding these two key aspects helps ensure your generator can reliably and efficiently meet your needs without being oversized or undersized.

What size home do you need to run?

Step 1: List all equipments you plan to use generator to generate electricity.

Step 2: Pinpoint both the continuous and startup wattages for each one on your list.

There are two crucial types of wattage for any appliance:

The chart displayed below provides running and starting wattages for common home devices:

Step 3: Calculate total power requirements

To work out total power needs of your generator:

1. Compute running power: Tally up the operational power of all appliances you need to engageconcurrently.

2. Add highest starting power: Determine which appliance has the highest starting power andinclude this in your total continuous power calculation. This accounts for extra power required tostart the most power-hungry appliance.

For example, providing power to a refrigerator, furnace and lamps:

• Refrigerator: 700W running, 2200W starting

• Furnace: 600W running, 1800W starting

• Lamps: 240W running, n/a for starting

Total running power: 700+1000+240 = 1940W

Peak starting power: 2200W (refrigerator)

Total power requirement = Running power tally +Maximum starting power

So in this scenario: 1940W + 2200W = 4140W

Given this sample, generator with minimum capacity of 4140W would be necessary to comfortably operate these appliances without overshooting generator's output provisions.

By adhering to these three steps, you can successfully calculate the total generator capacity needed to keep your home appliances running during a power failure. Always consider running and starting wattage to ensure your generator can handle peak loads and maintain steady operation.

The capacity of generator required to fuel your home is contingent on the extent of your electrical consumption. Certain homes might warrant higher power demands during blackout, while others might only need fewer appliances running simultaneously. Generally speaking, generator capable of producing between 5000 and 8000 watts can sufficiently energize an average home.

Other factors to consider when choosing the right size generator

Selecting right generator size is fundamental, but many other factors will also steer your decision, ensuring that you opt for ideal generator tailored to your unique requirements. Here's a rundown of some important factors to contemplate:
