automatic start.

You can configure this DHY125KSE generator work with an ATS unit (auto transfer switch) this protects your premises from power cuts around the clock. An ATS system will automatically detect a loss of power from the mains, start your generator and transfer the load automatically. It continually monitors the mains and transfers back when the power returns. Once set up this all happens without any input from you. ATS upgrades are sold separately though why not call us to discuss and we can recommend the precise system you need.


All Hyundai 1500rpm diesel generators also have the optional extra of remote monitoring and control. Using WiFi or GSM, you can start and stop your generator from anywhere in the world via a PC, laptop, smartphone or tablet. The benefit of having a 1500rpm generator for standby power is that it will have a much longer lifespan. Housed in a sound attenuated canopy, this generator keeps noise levels to a minimum to avoid disturbance and it’s also protected from the worst of the British weather.


All Hyundai 1500rpm diesel generator sound proof canopies undergo an anti-corrosion painting process called electrophoretic painting. This process ensures all areas of the canopy have an evenly applied thickness of paint, ensuring maximum corrosion protection and therefore protecting your investment.

When will I receive my order?

In most cases, a product on our website will give you an indication of the current stock availability, but shipping is not uniform for all products. We maintain fantastic relationships with all of our suppliers and we aim to get products to customers within 3 business days of the order being taken. This availability is based on information from our suppliers and from sales and supply patterns. The availability information given is a guide only and not a guarantee as there are external factors that we may not have control over.

1500rpm machines or larger diesel gensets however are typically priced on application and all depend on the destination. We will be happy to quote on any large diesel generator and discuss your needs over the phone or via email.

Most orders placed before 12pm on a business day will be shipped from our suppliers on the same day provided the product is in stock. If you need to be certain an item is in stock and available, or if you need a lead time, it’s worth calling our sales team on 01329 722390.

Heavy Items

You will be contacted by phone after ordering a larger item to confirm a delivery date before your order is dispatched. Large or heavy items are dispatched through a pallet network, so if we can’t get in contact with you, we may be unable to send out your item on a next day delivery. Please be sure to include a working phone number with your order.

Heavy items will require the recipient to make arrangements to take delivery of the goods and may require the recipient to help the courier unload the item. For items that are delivered on a pallet the courier will leave the pallet as close to your door as possible.

1500rpm diesel generators will require forklift (or similar) offloading; if this is not available then we can arrange a Hiab offload at an additional price – please call us to discuss any delivery requirements.
