Air conditioners come in small and large sizes, and one of the smallest is a 5000 BTU air conditioner used to cool RV’s, tents, and small spaces.

So, how big of a generator to run 5000 BTU air conditioner? It usually takes a 500-watt generator to run a 5000 BTU air conditioner, but a 1500-2000 watt generator would be ideal. But there are other factors involved as well. To learn more about it, keep on reading!

The Requirements of a Generator for a 5000 BTU Air Conditioner

These small air conditioners are best for people living in small rooms, RV’s, convertible vans, tents, or exploring the wild while setting camp at a single place. While setting up a cooling system, it is essential to know how much power they run. Simple math will reveal the answer.

To find how many watts are needed to run a 5000 BTU air conditioner, you have to divide the BTU number by 10. Here 10 is the Energy Efficient Ratio which is also known as EER. In this case, since the BTU number is 5000 so dividing it by ten is 500. Tada! You just deduced that your air conditioner uses approximately 500 watts of energy.

Although experts suggest that a 5000 BTU unit consumes from 417W to 625W, this is because the BTU and power are affected by the EER rating. The higher the EER rating, the better the efficiency, so the more cooling effect it provides per watt. So, when calculating how many watts are needed to run a 5000 BTU air conditioner, you have to consider the Energy Efficient Ratio, EER rating.

What Kind of Generator is Ideal for A 5000 BTU unit?

Air conditioners might function at 500W or any Watt mentioned in their specifications; however, they need extra power to jump-start the turning on the process for an air conditioner. Hence, you would think that a 500-600 W generator would suffice for these wonderful machines, but you would make a grave mistake. So, how big of a generator do I need to run a 5000 BTU air conditioner?

Since these power-house machines require a hefty amount of power to start machines, a 2000-watt generator will be perfect for these beasts. There are air conditioners that use low voltage, which can benefit from a generator with lower power. But these low-voltage models are far too scarce and challenging to get your hands on. Hence, for a regular voltage model, a 2000-watt generator is ideal.

Make Sure Other Appliances Can Run Simultaneously

Whether you live in a small room with its roots embedded in the ground or live in a small space that you drive around to cruise around the world, there isn’t just one kind of appliance that is attached to these homes. Hence, you will want a generator that caters to all your needs by supporting other appliances too. As a result, it is only fair to wonder what size generator to run the window unit and fridge as they are the two most essential appliances for a person. Again, a 2000W generator will suffice for operating different kinds of appliances simultaneously. Preferably, do not operate machines that consume more than 300 watts of energy. 

Things to Consider While Operating a Generator

An air conditioner only consumes a hefty amount of power when turned on, but it resumes to consume just a required amount of energy, as mentioned in its specification chart for the rest of the time.  As a result, you can plug in other appliances like fans, lights, televisions that do not take more than 300 watts to run. However, be mindful only to start other devices when your air conditioner has adjusted, or else there is a possibility for your generator to overload and malfunction.

Final Words

Air conditioners pull a ton of energy when turned on, but they consume adequate energy once they have been running for a little while. Hence, it is only fair if you wonder how big of a generator to run a 5000 BTU air conditioner, and the simple answer resides in how energy efficient the air conditioner is. The higher the EER ratio, the better cooling it can provide. Ideally, a 2000W generator would suffice for a 5000 BTU air conditioner, whether it is a window unit or a portable one.
