Updated - October 11th 2023

Whether you work in utilities, construction, manufacturing, events or on a site without mains power, HSS can get you up and running with a portable power generator.

Our fleet of generators offer a full range of power outputs from 1.6kVA to 60kVA as well as multi-socket outlets and low noise emission units.

Below is a diagram to that explains how you can choose the right generator for your needs.

Choosing the right generator

Calculating the kVA

At HSS, the Abird and APEX generator output is expressed in kVA units (kilovolt amperes). To find the usable output for your generator, you need to work out the kilowatt output.

First - Add up all the wattage of the pieces of equipment you need to power.

Next - Once you know how many watts you'll be working with, divide that by 1000 to get the kilowatts. For example, 1700 watts divided by 1000 = 1.7kW.

Then - Once you have your kW figure, you're going to then divide that by 0.8 to find your generator size in kVA units.

Once you've been through the steps to find the generators kVA, you'll need to take in to consideration the length of time you're going to require power. Will it be needed short term or will it be the only power source you have? When choosing your generator, we advise giving yourself a 20% leeway so you can be sure to have enough power. It's best to have extra power then not enough. We also advise using the generator to 70% capacity as they should only be ran at 100% for a short period of time.

Domestic or commercial?

Now the maths is out of the way, you need to think about the purpose of the generator. Generators are made for different purposes, both domestic and commercial so it's best that you choose one that's fit for purpose.

Petrol or Diesel?

If you're looking at petrol or diesel fuelled generators, you'll need to consider the cost needed to keep them going. Petrol generators costs less to run than diesel whereas diesel uses less fuel than a petrol generator.

At HSS we have a large fleet of the latest diesel generators from 20kVA to 1260kVA, available on short or long term contracts. As well as ancillary equipment and lighting towers, we also offer power solutions for all industries too. We can even supply, fit, service and manage all of your power requirements.
