Free UK Delivery*1,500rpm Diesel Generators
1500rpm Diesel Generators are ideal for static installation for daily prime power, as well as for regular standby generator/backup generator use both in the home and in your business.
1500rpm generators have slower running, water-cooled engines which are less stressed than the smaller 3000rpm air-cooled generators, which make them the best option if you’re going to use your generator as your main power source.
1500rpm generators are also able to provide a higher level of kVA than 3000rpm generators so could be the perfect solution if you’re looking to power larger appliances over longer periods.
Diesel generators are ideal for backup applications as sometimes petrol can go stale and prevent a generator working. Our diesel generators will happily run on red diesel, without voiding the warranty and making them more cost-effective.
We offer single-phase generators up to 28kVA and 3-phase up to 125kVA in the Hyundai range.
Our 1500rpm generators are ideal for use in your business, workshop or factory, or even as an off-grid prime power home generator.
These Hyundai generators can be installed with an Automatic Mains Failure switch or a Manual Transfer Switch to easily switch to backup power in the event of a power cut.

1,500rpm Diesel Generators - FAQs
Why do generators run at 1,500rpm?
Generators often run at 1500 RPM (Revolutions Per Minute) because this speed aligns with the standard for generating electricity at 50 Hz in many parts of the world. Running a generator at 1500 RPM ensures that it produces consistent and stable electrical output, suitable for powering homes and businesses. This synchronization with the electrical grid frequency is crucial to prevent issues like power surges and fluctuations, ensuring the safe and reliable distribution of electricity.
What is the best rpm for a generator?
The best RPM for a generator depends on factors such as the generator's size, design, and intended use. For most portable generators, 3,600 RPM (Revolutions Per Minute) is common, providing 60 Hz output for typical household appliances. However, larger generators designed for industrial or commercial use may run at lower RPMs for enhanced fuel efficiency and reduced wear and tear. Choosing the right RPM involves balancing power output, fuel consumption, and longevity to meet specific power generation needs.
Why would you need a 3,000rpm generator?
A 3000 RPM (Revolutions Per Minute) generator can be a practical choice for specific applications. These generators are often favored for their compact size, lightweight design, and portability. They are commonly used in small recreational vehicles, camping, and as backup power sources for essential appliances. The higher RPM allows them to generate power at 60 Hz, suitable for standard household devices. However, they may not be suitable for larger or industrial-scale power needs due to their limited output capacity. Choosing a 3000 RPM generator is ideal when you require a portable, efficient power source for smaller-scale uses.
