Generator Sizing

One of the most important things to bear in mind when buying or hiring a generator is the generator sizing. If the generator is too small you won?t have enough power to supply the equipment you need it for. If the generator is too big, you?ll be wasting money, generating too much power and paying out more for the generator than you need to.

Generator sizing, 24-Hour Generator Hire

The first thing to do when working out how big of a generator you need, is to calculate the load size. Make a list of everything that the generator will be used to power and calculate the total wattage. This information can be found in the handbooks for your equipment or direct from the manufacturers. It is important to use starting wattages in your calculations if they are higher than the running wattage.


kW to kVA Conversion

Once you?ve done that, you should convert your total wattage from kilowatts into kilo volt amperes. In order to work out the total kilo volt amperes, the following formula should be used:

kilowatts / power factor (0.8) = kilo volt amperes

In short, the kilo volt amperes value will be 80% of the kilowatt figure you calculated earlier.

You should then consider the requirements you have for running the generator. Will it be used for temporary or standby power or will it be your main power source? If it?s your main power source, you?ll need to ensure you?re not running at more than 70-80% capacity, and should allow accordingly. Generators should never run at full capacity for more than 30 minutes, so this gives you a 20-30% margin of safety.


Now you know the amount of electrical input you need from your generator, you should look at the location and site access requirements.?If the site is going to be difficult to access, you might need to position your generator offsite or use multiple smaller generators to split the power load. At this stage, you should speak to your generator supplier to see what the best option would be.

As an additional safety check, you should speak to a certified electrician before installing a generator. They will be able to ensure that your site is suitable and that the generator will be right for your requirements.
