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.
