Choosing the right generator size

Sizing options

There are two main options for generator sizing: standby generators and portable generators. Standby generators are permanently installed and are connected to your home’s electrical system, providing seamless power during an outage. Portable generators, on the other hand, can be moved around and are typically used for temporary power needs.

Standby generator

If you prefer a hassle-free solution and want your generator to automatically kick in during a power outage, a standby generator is the ideal choice. These generators are usually sized based on the square footage of your house, so a 2000 sq ft house would typically require a generator with a capacity of around 20-22 kW.

Portable generator

If you are looking for a more flexible and cost-effective option, a portable generator may be suitable for your needs. Portable generators are available in various sizes and wattage capacities. For a 2000 sq ft house, a portable generator with a capacity of around 5500-6500 watts should be sufficient, depending on your specific power requirements.

Determining load capacity

Load calculation

Load capacity refers to the amount of power a generator can provide. To determine the load capacity you need, calculate the peak load and running load of your appliances and devices. The peak load is the maximum power needed to start an appliance, while the running load is the continuous power it requires to operate.

Peak load

The peak load is usually higher than the running load and needs to be considered when sizing your generator. Appliances with motors, such as air conditioners, refrigerators, and pumps, often have a higher peak load due to the additional power required to start the motor. Ensure that your generator can handle these peak loads to avoid overloading and potential damage.

Running load

The running load is the power required to keep appliances running once they have started. This should be added up to determine the overall running load of your house, which will help you choose a generator that can handle the continuous power demands. Consider all essential appliances and devices that need to operate simultaneously during an outage.

Benefits of properly sizing the generator

Efficiency and cost-effectiveness

Choosing the right generator size ensures optimal efficiency and cost-effectiveness. A generator that is properly sized for your power requirements will operate at its most efficient level, consuming fuel more economically. This can help reduce fuel costs and maximize the lifespan of the generator.

Avoiding overloading

By correctly sizing your generator, you can avoid overloading the system. Overloading can lead to malfunction and potential damage to both the generator and your appliances. Proper sizing ensures that the generator can handle the peak loads and running loads of all your devices without putting excessive strain on the system.

Ensuring continuous power supply

The main advantage of properly sizing your generator is ensuring a continuous power supply during an outage. With a correctly sized generator, you can power all your essential appliances and devices without interruption, providing comfort, safety, and peace of mind.

Factors affecting generator capacity

Motor-driven appliances

Motor-driven appliances, such as air conditioners, refrigerators, and pumps, require a higher starting wattage due to the additional power needed to start the motor. These appliances can significantly impact the overall capacity of your generator, so it’s important to consider their wattage requirements when sizing your generator.

Starting wattage

Be mindful of the starting wattage of your appliances, as this is often higher than their running wattage. Appliances like refrigerators or air conditioners may need an extra surge of power to start up. Make sure your generator can handle these peak loads to ensure a smooth and uninterrupted power supply.

Power factor

The power factor is a measurement of how efficiently an electrical device consumes power. Some appliances, such as motors and fluorescent lights, have a lower power factor, which means they require more wattage to generate the same amount of useful power. Take into account the power factor of your devices when calculating the total power usage.

Efficiency rating

Consider the efficiency rating of the generator you are considering. A more efficient generator will convert more of the fuel it consumes into electricity, resulting in lower fuel consumption and increased cost-effectiveness. Look for generators with higher efficiency ratings to minimize fuel usage and maximize performance.
