How to pick the right Diesel Generator

Picking the Right Diesel Generator

Picking the right generator is a must if you want it to last as long as possible, and produce the right amount of power when you need it! Without knowledge of how generators work or what the key terminology means, it can be a difficult task sifting through all the information to find what is relevant to you. As such we have compiled this blog article to help you make the right choice, one question at a time.

What is the Application?

First up, the use case. If you need the generator running constantly with no breaks, then you'll be after a prime generator. These generators are used as a Prime source of power and often have a lower apparent power than that of a standby. On the other hand, if you are wanting to use the generator occasionally, or as a backup form of power, you'll be wanting a standby set. These gensets offer Standby power for when you need them.

TL;DR - If you need a generator to run permenantly, look at the Prime kVA rating. If you need one for standby usage only, look at the Standby kVA rating

What Power is Required?

With terms like 'kVA' and 'kWe' being thrown around all the time, it's no wonder that people get confused. There are many ways to calculate power requirements, from simply adding up the connected load to calculating diversity of use over time, to considering the maximum potential demand.

You should consider power in two ways, both real power (also known as kWe) and apparent power (also known as kVA). The difference between the two is known as power factor and this is normally specified by convention at 0.8 (so a 500kVA set may only provide 400 kWe of power).

TL;DR - The difference between kVA and kWe is that kWe is real power, where as kVA is apparant power.

What Conditions are you Using the Set In?

It's important to note what climate and conditions you will be using the generator in. Is it a residential area (so quieter is better), or is there a size restriction? Knowing all the conditions the generator will be in before purchasing a set helps make the process a whole lot easier. For example, if you know you need the generator to be as quiet as possible, you may want to purchase an open generator rather than a silent generator. Alternatively if size is of a large constraint, an open set may be smaller than a silent enclosed set.

Knowing temperature conditions and environmental conditions are also exceptionally useful, but a bit harder to differentiate what type of set you need. So if you want more information visit our contact us page or get in touch using our live chat feature.
