Before buying a backup generator for providing power to the air conditioner during a power outage you need to look into a lot of factors, one of them being the size of the generator. this article will clear your doubts based on which size and wattage of generator you should use to run an air conditioner.
What size of generator is needed to run an air conditioner?
- A standard air conditioner approximately needs 1000 watts for that you need to run a generator that is able to provide the wattage of 1000 watts.
- If the AC is required to use for an hour or two every day then you required a generator that is able to provide 500 watts of power.
- If you are using the air conditioner for long periods for example 8 hours each day then you need a generator which is able to provide at least 2000 watts of power.
There are various things to be considered to find out which size of generator to run an AC such as:
- Firstly you should look for the wattage consumed by an air conditioner that can be seen on the label mentioned AC. A typical window air conditioner does need a wattage of upto 1000 watts.
- The second point you need to check is the start-up wattage which means the power that the AC requires at the starting stage because the power consumed will always be higher than the power consumed at the running time. You can determine the startup wattage on the AC unit itself or on its manual of it.
- The third point is to look at the surge wattage as it is the amount of power which is required to run an AC unit and it is not required continuously
