New Generators
How do I choose the right generator for my power needs?
Firstly, you need to know how much power you would require, and then how many phases your system runs on.
If you’re unsure, fill in our Contact Form and give us as much detail as possible. One of our colleagues will be in touch to assist you.
How long does diesel last in a generator?
How much diesel a generator uses will depend on its size and how it is used.
Often generators come with an internal fuel tank. These are usually designed to allow that particular generator to run for 8, 10 or 12 hours. If the generator is not in constant use, then the fuel will sit in the tank. The diesel, if stored correctly, will last a long time.
The biggest factor is water getting into the tank or biological agents developing within the fuel. However, this does not render the fuel useless. If the tank is emptied and cleaned and the fuel is filtered, it can be used again.
Get in touch via our Contact Us page to arrange this.
Can I get an automatic transfer switch with my new generator?
Yes, we highly recommend pairing your generator with an automatic transfer switch for seamless power during power outages.
How much fuel does a new generator use?
Fuel consumption depends on the size and load. For example, a 20kW diesel generator might use 1.6 gallons per hour at 50% load.
How to calculate amps to kVA?
To calculate the kVA a generator produces, you need to know either the number of KiloWatts (kW), the Voltage (V) or the Ampages (A) the generator provides.
You can go straight to our kVA Calculator to take care of all of the figures!
What’s the difference between air-cooled and liquid-cooled generators?
Air-cooled units are smaller and ideal for residential use, while liquid-cooled systems are larger, quieter, and better for commercial applications.
What are the safety features on new generators?
New models include features like overload protection, low-oil shutoff, and remote monitoring. We’ll explain these features during your purchase.
What size diesel generator do I need?
The size of the generator needed is all dependent on the supply and demand.
All individual appliances demand a certain amount of power (measured in watts) and generators supply a certain amount of power (also measured in watts).
You need to ensure enough power is supplied to operate and fulfil all of the power requirements for all equipment.
Do new generators qualify for energy rebates or incentives?
Depending on your location and the model you choose, you might qualify for rebates or incentives. We can help you find eligible options
Used Generators
How can I tell if a used generator still has a good lifespan left?
Check the total runtime hours—generators designed for industrial use can last tens of thousands of hours if maintained well. Look for units with low-to-moderate usage and a solid service record.
Do used generators come tested and inspected?
Yes, we thoroughly inspect and test every used generator to ensure it’s in good working condition before offering it for sale. Ask us for the inspection report.
Are spare parts still available for older used generators?
Most models we sell have parts readily available, but we can also help you source hard-to-find parts if needed. Let us know the model, and we’ll guide you.
Can I trade in my old generator for a used one?
We offer trade-in options where you can exchange your old generator for a newer used model. Contact us for a valuation of your unit.
Can I see a used generator in operation before purchasing it?
Of course! We’re happy to demonstrate the generator under load conditions so you can see how it performs.
Where can I sell a generator?
Just contact us!
Go straight to our Sell Your Generator page and send us your details. One of our colleagues will be in touch to offer you a great price.
Service and Maintenance
What’s included in your maintenance services?
Our maintenance includes oil and filter changes, fuel system cleaning, load testing, and overall system checks to ensure reliable operation.
Can you service generators not purchased from you?
Yes, we service all major generator brands, regardless of where you bought them.
What’s a load bank test, and do I need one?
- A load bank test simulates full-load conditions to ensure your generator can handle its rated capacity. It’s essential for standby generators used in critical applications.
Can you use red diesel in a generator?
Most generators on the market are diesel generators, and yes, you would generally use red diesel in these as they cannot be used on public roads. You can also use normal diesel, but this would be a lot more expensive to run.
We can supply fuel to your diesel generator at great prices per litre, just visit our Contact Us page and we’ll be in touch to make the arrangements.
What causes generators to fail during an outage?
Common reasons include old fuel, battery failure, or neglected maintenance. Regular servicing minimises these risks.
Do you offer emergency generator repairs?
Yes, we have a team available for 24/7 emergency repairs to get your generator back online quickly.
How do I store my generator when not in use?
Store it in a dry, ventilated area with the fuel drained and the battery disconnected. We offer storage tips and accessories to help.
What’s the warranty on your maintenance services?
We guarantee our work and parts for a specified period, depending on the service. We’ll provide clear warranty terms upfront.
