Investing in a 30kVA diesel generator means long-lasting performance, fuel efficiency, and reliable power whenever you need it most.
Is a 30 kVA generator sufficient for agricultural use?
Yes, a 30 kVA generator is more than sufficient for many agricultural applications. It can power irrigation systems, barn lighting, milking machines, feed systems, and small machinery. It’s particularly valuable in rural areas where power outages can disrupt operations. By ensuring reliable power, a 30 kVA generator helps maintain productivity and protects against losses due to equipment downtime.
How do I choose between a single-phase and three-phase 30 kVA generator?
The choice between a single-phase and three-phase generator depends on the type of equipment you need to power. Single-phase generators are commonly used for residential and light commercial applications, where the power demand is lower. Three-phase generators, on the other hand, are suited for industrial and agricultural applications that require more power, such as heavy machinery or large HVAC systems. Three-phase generators provide smoother and more efficient power delivery, which is essential for equipment that draws a large load.
What is the fuel consumption of a 30 kVA generator?
A 30 kVA generator typically consumes around 6 to 7 litres of diesel per hour at full load. This consumption rate can vary depending on the generator’s efficiency, load percentage, and operating conditions. Regular maintenance, such as keeping filters clean and using high-quality fuel, can help optimize fuel efficiency and reduce operating costs.
How much does a 30 kVA generator cost?
New sets this size typically run about £6,000 to £11,000 ex VAT, depending on engine brand, canopy and options such as a transfer switch. Most are built to order, so enquire for a firm quote.
What can a 30 kVA generator power?
It powers larger sites, farms, workshops and small factories, running three phase machinery, welders, pumps and retail units, delivering about 24 kW of continuous power for that duty.
Do you provide installation services?
Yes. Our professional team can arrange full installation, including delivery, siting, cabling, and commissioning, so your generator is ready to run safely and reliably.
Are 30kVA generators noisy?
We supply both open frame and silent canopy models. Open sets are cost-effective for industrial and remote sites, while silent generators are designed for use in residential or noise-sensitive areas.

How many amps does a 30 kVA generator give?
Around 43 amps per phase on a 400V three phase supply. Always size against your real load and starting currents.
How much fuel does a 30 kVA generator use per hour?
Roughly 3 to 6 litres an hour depending on load, and less at part load. Sizing to your true demand keeps fuel down.
