Generator Buyers Guide: Which Generator Should I Order?

Diesel Generator Direct offers a broad range of diesel generators, and each is suited to a slightly different type of commercial or domestic application. Choosing the right one for you and your home or business might seem a bit overwhelming, so we’ve put together this guide to help you narrow the possibilities down to a few good choices. Our friendly, helpful staff can then help you make the final decision.

Where to start

There are four big determinations you need to make to narrow the field down to a few really good possibilities.

1)    Do you need a domestic or professional-grade genset? Some gensets are better suited to supply power to a single home or for leisure/hobby applications. Others are designed for commercial use or more extensive workshops.

2)    Will you need a primary power generator, or a standby generator? A primary power genset is intended to be used more or less constantly, whilst a standby genset is intended to ‘kick in’ quickly in the event of a power cut or brownout.

3)    Will you need an inverter? If you’ll be running sensitive devices like computers or televisions directly off the genset, you’ll need an inverter generator.

4)    How much power do you need? There is a detailed guide to calculating your power needs below.  Always make sure to allow a safety margin!

 

which diesel generator Domestic or Professional Use?

–using a domestic grade genset for commercial purposes will probably void the warranty.

The basic technology behind our professional and domestic lines of gensets are not all that different. The main difference is really the type of use they are intended for, and the terms of their warranties.

Domestic generators are designed to be used for back-up power during storms or power line maintenance, for providing small quantities of easily portable power – say for power tools, camping or other hobby use. They tend to be light, portable, durable and usually only boast modest fuel capacities. They are perfect for camping or garden use, or to keep the lights on when the national grid can’t, but you wouldn’t use one to run heavy equipment or a whole store.

If you plan to use a genset commercially, or to rely on it for power pretty much every day in any capacity, you really need a professional grade genset. They also come with long-term, commercial use warranties, so you know you can rely on them to keep your business running or for any truly important purpose.

We also offer a series of midrange professional grade gensets which feature full commercial warranties, but are at a lower price point and better suited for backup power or more sporadic commercial use.

Better still, professional grade gensets come in all shapes and sizes. That means you won’t need something that could power the whole neighborhood if you only have to supply a few hundred watts in a very reliable, steady fashion.

Standby Generators:

A standby generator is ideal for back-up or emergency power, but should not be used constantly for days at a time.

Work or play, at home, at the office or on a worksite, there is nothing more disruptive, frustrating, and occasionally expensive as an unexpected power cut. Business and residential customers all over the UK are discovering that the nation’s aging power grid was developing problems even before the shift to more ecologically friendly yet highly unreliable renewable energy sources.  To domestic customers, this might not mean more than inconvenience and an argument over whether you actually own candles anymore. At work, though, these sudden cuts can damage machinery, destroy data and leave your entire workforce standing around for hours at full pay but zero productivity.

The solution more and more people are relying on at home and at work is a backup power genset. A backup power installation requires 3-4 pieces.

-A reliable, efficient and fast-starting diesel motor

-An electrical generator for the motor to turn

-A transfer switch to ‘cut in’ the generator when the power grid fails

-An optional battery or capacitor power bank to keep the lights from flickering and your PCs from crashing in the few seconds when the genset gets itself up to speed.

A manual transfer switch (MTS) does just what it says on the tin – you have to switch your home or business’ power over to the standby generator manually by pressing a button. The actual control is easy to install nearly anywhere, so you won’t necessarily have to go out into the shed to turn on your genset.

An Automatic Transfer Switch (ATS) is much easier to use. The ATS is computerized, and can sense when the power levels supplied by the grid drop to unacceptable levels or cut out entirely. It then sends the command to start up the genset on its own, any time of the day or night. Within a few seconds, the lights come back on and you can carry on just as before. Of course, when the grid once again sends power your way reliably, the ATS switched you back to the power grid and shuts off the genset.

Needless to say, a standby genset can salvage the day’s productivity at nearly any kind of commercial or industrial site. Even at home, though, there is more at stake than the potential of missing the footie. Depending on your homeowner’s insurance provider, a standby genset can reduce your insurance rates. It is also likely to increase the value of your home even if you never use it.
