This generator is equipped with an AVR alternator which produces a clean and stable power supply this makes it perfectly safe to use with sensitive electronic appliances.

Hyndai DHY125KSE – 125kVA = High Power Output

The high power output of this Hyundai DHY125KSE generator ensures that it can easily power a substantial family home with even the most demanding requirements. Estate owners will also benefit from this powerful generator if one large or several smaller buildings need power at the same time.

Standby Power Pays for Itself Hyundai DHY125KSE

Power cuts cost UK businesses millions of pounds every year and a standby generator such as this Hyundai DHY125KSEis designed to protect your revenue. If your business relies on a server room, online sales, refrigeration or freezers, then regular or extended power cuts can be disastrous for your finances. A generator like this can pay for itself quickly in these circumstances.

Automatic Start on The Hyundai DHY125KSE

You can configure this Hyundai 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.

Remote Monitoring – Updates You on The Power Status Wherever You Are

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.

Designed for Long Service Life

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.
Note – this unit is hard wired busbar connection only – no sockets are included. For the recommended usage of this generator, please see here.

Hampshire Generators can also maintain your generator with a regular cost-effective service plan or one-off visit. Simply call 01329 722390 or inquire via contact us page for more information.

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.

Coronavirus Update – UK couriers and transport companies will not currently guarantee delivery times and we are seeing a slight delay in deliveries – please bear this in mind when ordering.

Specialist Couriers – Some items such as the larger portable power stations are sent by specialist courier as standard couriers will not accept them. These specialist couriers are very reliable but sometimes don’t have tracking or timed delivery.

Split deliveries – We sometimes need to send orders for more than one item by different courier networks (portable power stations for example) – so you may receive items at different times.

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. Pricing for extended shipping areas like Northern Ireland, the Scottish Highlands and outlying Islands, Outer Hebrides, Channel Islands, Isle of Man, Scilly Isles, and other postcodes not considered as UK mainland can be obtained also by calling our offices.

Please note that the processing of a payment and acknowledgement email does not constitute a legally binding contact. In the case of mispricing, changes in stock quantity, or if we believe the machine will be misused, we reserve the right to cancel the order and provide a full refund.

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.
