How to choose a diesel generator

While the decision to invest in a diesel generator is an easy one to make – they’re reliable, cost-effective, easy to maintain and a lifeline against power cuts – choosing the right one might not be such a quick choice. This is because ensuring your standby generator is the right one for you is really important – it’s an investment that can affect your revenue, profits, productivity and more.

Rather than rushing into the decision or going it alone, why not contact our Vital Power team to discuss your options? We stock a wide range of UK leading brand names in our standby generator collection, and can also offer custom-built generators to find your perfect match.

So, what do you need to consider before choosing the right diesel generator for you?

Choosing the right budget for your generator

While diesel generators are one of the most cost-effective and efficient options, purchasing one (or choosing generator hire) is a significant financial situation. So, have an ideal generator budget in mind when you’re looking for a backup power solution.

At Vital Power we are specialists in generators and UPS (uninterruptible power supply) solutions, so we can help discuss your needs and find options that suit your budget.

Thinking about the space you’ll need for your generator

Evaluating and measuring the actual space you’re working with at your premises is crucial. Some high-quality generators feature a number of heavy components, which subsequently make the unit rather large. Naturally, generators for businesses like hospitals or agriculture facilities might need huge power output from their backup generator, which means a fairly sizeable piece of equipment.

You’ll need to think about the space you have at your business before you start planning for a generator – deciding the power output and generator type will dictate the space you need.

It may involve laying new concrete paving or foundation, or perhaps investigating new space for your backup power solution. Our team would be happy to do a site audit to make suggestions. As part of our comprehensive service offerings, we can ensure your generator always remains in top condition with a tailored service and maintenance plan, designed specifically for your site.

What size generator do you need?

Imagine the scene – you’ve bought your generator and gone through installation, only to find it lacks the output necessary to keep your operations up and running. At Vital Power our team won’t let this happen, and will thoroughly assess the size and output of generator you need.

We’ll add up the necessary power requirements for your business, and suggest a wide range of top generators to choose from that will suit your needs. In the long term, generator service and maintenance packages will help make sure your generator is operating at full capacity, and load bank testing will help make sure you’ve got reliable backup power when you need it.

How loud are diesel generators?

Naturally, standard generators can produce some noise, owing to the huge amounts of power they generate and the important job they do. If you’re keeping your industrial generator out away from buildings or other businesses, this might not be an issue. For example, you might house your generator with other large scale machinery or in a warehouse.

However, if you do have concerns about generator noise levels or need to put your power solution close to where people work or other businesses, a silent diesel generator may be the best option. Our team can help advise on the right choices for you with a site audit.

Where to buy a diesel generator

By now, you should have started to gain some sort of idea of what your ideal generator looks like. However, you might not quite know where to start or how to buy a generator.

Luckily, Vital Power is a company that is well-known for stocking diesel-fueled backup generators in all shapes and sizes. Our team works 24 hours a day year round from our UK-wide operational hubs, and can help with any query, emergency or issue. We’d be happy to discuss what’s right for your business and suggest the best generators for your needs.

Got a question? We’re always happy to help.

"I wanted to say a big thank you for the way my generator was installed by one of your engineers. It was done extremely professional and quickly. The engineer projected a tremendous sense of enthusiasm and confidence – and his small-talk is also most interesting to hear. I was left in awe of his complete understanding of the installation requirements. He even management to iron out a difference on the auto start that the manufacturer did not tell him about. A very clean and good working in all respects, he is a tribute to your company"
