It produces the 5kVA / 4Kw of power effortlessly in spheres such as large motorhomes, powering air-conditioning units, power tools, televisions, and more besides. Plus has the added benefit of having a remote electric start key fob.

At just 50kg the Hyundai HY4500SEI is perfect portable generator for your needs. Getting the power where you need it has been made easy. There is an integrated wheel kit with the Hyundai HY4500SEI. Its robust wheels and folding handles makes it a total breeze to move about to wherever you need it.

Using Sensitive Equipment with The Electrical Power from The Hyundai HY4500SEI

The power produced by the Hyundai HY4500SEI leisure generator enables a smooth voltage output via the Hyundai’s AVR alternator. Using the latest Hyundai digital inverter technology, the generator can cope with the extreme inductive loads such as; using power tools and electric motors with high start-up currents. It keeps the 230v output within a +/- 3% tolerance making it safe to use with electronic equipment like PC’s, laptops TV’s and more besides. However, the Hyundai’s AVR alternator is sturdy enough to cope with building site equipment and the power tools and paraphernalia within that industry.

Is the Hyundai HY4500SEI Easy to Start and Use?

You bet it is – simply push the remote electric start key fob and up it starts! The electric start button makes starting straightforward and there is also a recoil start too as a backup, so you are never let left without any power. The battery on the Hyundai HY4500SEI recharges itself when in use. And has a run time of 7 hours @ 50% load / 3.5 hours @100% load for long continued use on a full 9 L tank of fuel.

There is an “ECO” mode which, when selected, will lower the engine speed to match the load applied to the generator, which in turn increases the fuel economy, lowers the noise produced and extends the lifespan of the engine.

What Sockets Does The Hyundai HY4500SEI Have?

There are 2 x 230v / 13a sockets & 1 x 12v 5amp DC sockets fitted to the Hyundai HY4500SEI to connect your electrical equipment up to. An easy to read onboard digital display is on hand so you can see information such as, hours run, output voltage and frequency. This is important as you will need to know when your generator will need servicing after the scheduled hours run time has been reached, this will keep your generator maintained and running for thousands of hours use.

What Happens If I Do Not Use My Hyundai HY4500SEI For Long Periods?

As with all petrol engines, if you are planning to store your generator for a long period its ‘best practice’ to either drain the fuel tank then run the generator until it stops. This will prevent any unused fuel congealing and clogging the carburettor. Or to stop the fuel from going off use a petrol additive. Remember, stale fuel can stop your generator from starting when you need it.

Low Noise Levels

You might think having a petrol generator will be very noisy. Well think again; the Hyundai HY4500SEI is surprisingly quiet at 59 dBA @ 7 metres at 50% load.

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.
