Recommended Generator Sizes for a 13500 BTU Air Conditioner
When it comes to choosing a generator to run a 13500 BTU air conditioner, there are a few different options to consider.
Here are some recommended generator sizes to consider:
A 3500-watt generator is the minimum recommended size for a 13500 BTU air conditioner.
This generator will provide enough power to run the air conditioner, along with some additional small appliances or devices.
A 4000-watt generator provides a little more power than a 3500-watt generator, which is useful if you have additional appliances or devices.
That needs to be powered at the same time as the air conditioner.
This generator will also have some additional capacity to handle occasional spikes in power demand.
A 5000-watt generator is a good option if you have multiple larger appliances or devices.
This generator will provide ample power to run the air conditioner along with other larger appliances, such as a refrigerator or microwave.
A 6000-watt generator is a good option for those who want some extra power capacity for occasional spikes in power demand.
This generator can handle a 13500 BTU air conditioner along with other large appliances or devices without the risk of overloading the circuit.
Factors to Consider When Choosing a Generator Size
When selecting a generator size to run a 13500 BTU air conditioner, there are several factors that you should consider. These include:
Power requirements of the air conditioner
Check the air conditioner’s user manual to determine its running wattage.
Consider the air conditioner’s start-up wattage, which is typically twice the running wattage.
Other appliances that may be running simultaneously
Determine the wattage requirements of other appliances that may be running simultaneously with the air conditioner.
Add up the total wattage requirements to determine the generator size needed.
Altitude and temperature of the environment
Consider the altitude and temperature of the environment where the generator will be used, as these factors can affect the generator’s performance.
A generator’s power output decreases as altitude increases, and it may need to be derated in high-temperature environments.
Fuel type and availability
Consider the fuel type that the generator uses like gasoline, diesel, propane, or natural gas.
Determine the availability and cost of the chosen fuel type in your area.
Calculation of Generator Size for a 13500 BTU Air Conditioner
To calculate the generator size needed to run a 13500 BTU air conditioner, follow these steps:
Determine the Running Wattage
The running wattage of the air conditioner can typically be found in the user manual or on the manufacturer’s website.
For a 13500 BTU air conditioner, the running wattage is typically around 1200-1500 watts.
This is the amount of power required to keep the air conditioner running once it has started.
Factor in Surge Power
When the air conditioner is first turned on, it requires a surge of power to start up.
This surge power is twice the running wattage. For a 13500 BTU air conditioner, the surge power will be around 2400-3000 watts.
It is important to factor in this additional power requirement to ensure that the generator can handle the start-up load.
Consider Additional Loads
There can be other appliances or devices running on the circuit.
It is important to factor in the power requirements of these additional loads to ensure that the generator can handle the total power demand.
Add up the wattage of all additional devices that will be running at the same time as the air conditioner.
Choose a Generator Size
Add together the running wattage, surge power, and additional loads to determine the total wattage required.
When selecting a generator, choose one with a capacity that exceeds the total wattage required to ensure optimal performance.
For a 13500 BTU air conditioner with additional loads, a generator with a capacity of at least 3500 watts is recommended.
This ensures that the generator can provide enough power to run the air conditioner and any additional loads without overloading the circuit.
Types of Generators for Running a 13500 BTU Air Conditioner
When running a 13500 BTU air conditioner, there are a few different types of generators to consider.
Here are three types of generators that are commonly used for this purpose:
Portable generators are popular because they are affordable, easy to use, and can be moved around as needed.
These generators run on gasoline or propane and come in various sizes, from small 2000-watt units to larger 8000-watt models.
Inverter generators are a more expensive option than traditional portable generators, but they offer some unique benefits.
These generators produce clean, stable power that is safe for sensitive electronics and appliances, which can be especially important if you are running a high-end air conditioner.
Inverter generators are also quieter and more fuel-efficient than traditional portable generators.
Standby generators are a permanent backup power solution that can be installed outside your home or business.
These generators are designed to turn on automatically and provide enough power to run a 13500 BTU air conditioner along with other appliances and devices.
Standby generators typically run on natural gas or propane and are more expensive than portable or inverter generators.
Tips for Running a 13500 BTU Air Conditioner on a Generator
Running a 13500 BTU air conditioner on a generator requires some careful planning and attention to detail.
Here are some tips to keep in mind to ensure that your air conditioner runs smoothly and safely on your generator:
Choose the Right Size Generator
Make sure that you choose a generator with enough power to run your air conditioner without overloading the circuit.
You will need a generator with a capacity of at least 3500 watts to run a 13500 BTU air conditioner.
The actual size of the generator depends on the identification of the air conditioner, so check the manufacturer’s website or user manual for specific power requirements.
Factor in the Surge of Power
When choosing a generator size, make sure to factor in the surge power required to start your air conditioner.
Surge power is the extra amount of power required when the air conditioner first turns on, which is twice the running wattage.
Choose a generator with a surge rating that is at least twice the running wattage of your air conditioner.
Use the Right Type of Extension Cord
Use the right type of extension cord to connect your air conditioner.
Look for a heavy-duty, outdoor-rated extension cord that is designed to handle the wattage of your air conditioner and generator.
Keep the Generator Away from the House
Keep your generator at least 20 feet away from your house and any windows or doors. Never run a generator indoors or in a garage.
Turn Off Non-Essential Appliances
To avoid overloading the circuit, turn off any non-essential appliances or devices when running your air conditioner on a generator.
This will help to identify whether your air conditioner has enough power to run smoothly.
What Is Surge Power, And Why Is It Important When Choosing A Generator Size?
Surge power is the extra amount of power that is required when an air conditioner first turns on.
This amount is typically twice the running wattage. It’s important to factor in surge power when choosing a generator size to ensure that the generator can handle the initial power draw of the air conditioner.
Can I Run A 13500 BTU Air Conditioner On A Smaller Generator?
It’s not recommended to run a 13500 BTU air conditioner on a smaller generator as it can overload the circuit and potentially damage the air conditioner.
It’s best to choose a generator that is at least 3500 watts and has a surge rating of at least 7000 watts.
Can I Run Other Appliances Or Devices At The Same Time As My Air Conditioner On A Generator?
Be careful not to overload the circuit when running an air conditioner on a generator.
It’s recommended to turn off any non-essential appliances or devices to ensure that the air conditioner has enough power to run smoothly.
Can I Run A 13500 BTU Air Conditioner On An Inverter Generator?
Yes, you can run a 13500 BTU air conditioner on an inverter generator as long as the generator has a sufficient power output.
Inverter generators are known for their fuel efficiency and quiet operation, which can make them a good choice for powering air conditioners in outdoor or camping settings.
Choosing the right size generator to run a 13500 BTU air conditioner is essential to ensure optimal performance and avoid potential damage.
It’s important to consider the running wattage, surge power, and other factors such as the type of generator and tips for running the air conditioner.
By following these guidelines and selecting the appropriate generator size, you can enjoy a comfortable indoor temperature even in the event of a power outage or while off-grid.
