Acquiring a generator that can supply power is a critical exercise. The hardest part of it all is determining the right size of the generator you need to meet your requirements.
Generator size variations
With the current trend of technology advancement in the field of electric engineering, we now have a wide range of generator sizes available.
There are those designed for household uses their sizes range from 5kW to 50kW. These are convenient for personal use at home.
For industrial generators the sizes available ranges from 50kW to 3 Megawatts. There are also handy generators that are available for homes, small offices and RV’s.
Large businesses, data center buildings, and industries, however, need to utilize industrial generators of large sizes to meet their desired requirements.
Generator sizing, how much power?
There are many individuals out there who still believe that smaller generators can be used for standby electric power due to the fact that they are not running all the time. This kind of belief can be very detrimental.
It is true that the generator under sizing is one of the most common mistake usually committed by buyers.
It can lead to damage of your asset beyond repair. This means all the appliances connected to it may be at risk of damage.
Moreover, it may even limit the overall productivity of the business or unit relying on it for power supply.
How to determine the right size of a generator.
It is true that an electric technician is the best person to inspect and calculate all you need to know about the size of a generator.
However one should avoid going to a generator dealer and buying the cheapest of them all. One should at least look at the following in order to determine the right size.
-You need to make a list of items that you will require to be run electric power from the generator.
-you also need to make a note on the starting and running wattage of the given respective items
-you also need to calculate the total power requirements in the form of KW or KVA
How do you find the starting and running wattage?
What you need to do look for is the owner’s manual or the identification plate of all the appliances you intend to use.
On the part of ampere- watt conversion, you will first note the recorded amount then convert it using this formula;
-For resistive load, wattage equals amperes multiplied by volts.
-For reactive load, wattage is equal to amperes multiplied by volts multiplied by the load factor.

Generators are devices that can be confusing at times. Generator sizing calculator excel saves you all this headache.
This sizing calculator is able to give you the correct reliable kW rating. The moment you have the accurate kW reading then getting the right generator becomes a piece of cake. It saves you a lot of trouble trying to figure out which size suits you best.
Generac generator sizes
Choosing the right Generac generator size is not easy. Here are some of the things you need to consider in order to choose the right size of your Generac generator.
One of the most critical considerations when choosing the right Generac generator is whether it will meet its intended purpose supplying sufficient power to your intended appliances.
Coming from one phase 120V for the regular household needs to that of three-phase 208V and beyond, it is probably wise to step up the generator that provides the next level of power than you possibly require.
Consider the generators sound output.
Sometimes these generators can be so noisy. These high levels of noise can be an issue, especially in residential areas.
You should, therefore, choose a generator that is designed to operate quietly.
Look at the portability requirements.
This is one of the very first things one looks when purchasing a generator.
You must understand there is a real difference between permanently installed backups and portable generators. So you will consider according to the requirements and the needs you have.
You should know that generic generators come in either air cooled or liquid cooled models. Air cooling system is usually convenient for generators of small sizes like those used for household purposes. It is an economic method too.
For large size generators that are meant for industrial purposes a more powerful liquid cooling system is preferred.
The above discussion clearly describes how one can choose a generator according to the size.
It is important to understand the sizes of these devices so that one can easily identify the generator that will meet their desired purpose.
