What Size Generator Do I Need?
Whatever size you need, Powerlite has your ideal generator
Small Portable Genset
The ideal generator size is one that is correctly matched to power all the things you want to run at the same time. If it is too big, not only will it be more expensive to purchase, but it will not necessarily run as efficiently as the correctly matched size. If it is too small, some of your equipment may not give it maximum output, and consequently its lifespan may be reduced. We recommend using the calculator below to find out your ideal generator size. If you would like further information into how we calculate the right small 240v generator, please refer to the wattage worksheet below. Please note that the below wattages are simply a guide. For correct wattages, please check the specific power tool or appliance.
Larger Industrial Genset.
Selecting a generator that can handle all your power generation needs is one of the most important aspects of the purchasing decision. Whether you are interested in prime, temporary or standby power, if your new generator can’t meet your specific requirements then it simply won’t be doing you any good because it can put undue stress on the Generator and even damage some of the equipment connected to it. Unfortunately, determining exactly what size of generator to purchase is often exceedingly difficult and involves a number of factors and considerations.
Making a choice amongst single phase, three phase, kW, KVA, welder, standby or motor starting generators can be confusing. To prevent such confusion, Powerlite has written this article to help you get a better idea of how the sizing process works and some key things to keep in mind. This is not a substitute for a certified electrician, which we always suggest talking to before Purchasing (Powerlite can assist you here), but it should provide you with enough information to get an understanding of some of the key factors that are involved.
Generator Size Variations:
With the latest advancements in the field of power generation, Powerlite supplied and built generators are now available in a wide range of sizes. Powerlite Generators with power supply capacities of 1Kva to 80Kva are readily available for the home use, while Australian industrial generators are anywhere from 50Kva to over 3 Megawatts. Powerlite can build multi set applications where up to 32 generators can be synchronized to work as 1 (96 Megawatts). Portable Generators are available for homes, caravans and small offices, but larger businesses, data centers, buildings, and mining applications need to use a much larger sized Diesel generator / generators to meet their power requirements.
Generator Sizing :
Many people believe smaller generators can be used for standby power because they are not running all the time. This is not only wrong but can be very damaging. Unfortunately, generator under sizing is one of the most common mistakes committed by purchasers. Not only does it involve the risks of damaging your new generator, but it can also damage other assets connected to it, create hazardous situations, and even limit the overall efficiency of the unit and/or the business relying on it. If nothing else, the key thing to remember here is that more is always better than less.
