Hyundai 4000W Petrol 4.0kW / 5kVA Portable Inverter Generator

The HY4500SEi is a compact yet extremely powerful portable inverter generator from Hyundai. Providing a convenient and cost-effective source of power this portable inverter generator is the perfect generator for domestic requirements along with providing power whilst camping or in a caravan away from mains power.

4 Stroke Engine Power

Powered by the Hyundai HY225E 223cc 4-stroke OHV engine, producing a max output of 4000w / 5kVA and continuous power of 3200w / 4kVA, the HY4500SEi is capable of powering microwaves, hair straighteners, air conditioning units, televisions, small air compressors for inflatable beds, electric heaters, power tools, laptops, lights and much more allowing you to take the modern luxuries from home with you wherever you go.

Portable Power

The compact symmetrical design allows effective storage, transportation and manoeuvrability. Weighing 50kg combined with the folding front, moulded rear soft-grip handle and heavy-duty rear wheels make transportation easy across a variety of surfaces.

LCD Display Screen

The HY4500SEI houses the latest Hyundai digital inverter technology designed to cope with the extreme inductive loads applied when using power tools and electric motors with high start-up currents. The LCD display makes it easy to monitor the performance of the generator, displaying voltage, frequency and hour count.

230v Sockets

The control panel features two 230v sockets for use with any appliance which uses a standard 3-pin 13A UK mains plug, as well as a 12v DC battery charging outlet. The HY4500SEi is a very low noise generator based on the average 50% load, the noise level is 59dB at 7m.

Clean Power For Sensitive Equipment

Producing a pure sine wave output, it can safely power sensitive electronics without the risk of damaging or overloading them. Starting the generator is simple after connecting the battery and switching ON, simply press the start button on the key fob and the generator will start immediately, there is also a recoil pull-start backup for emergency situations.

Low Maintenace Generator

Built to be user-friendly with low maintenance requirements the HY4500SEi features digital overload protection which will shut the generator down should the load pass the maximum threshold, and low oil shutdown also turns off the generator should the oil levels drop too far.

ECO Mode

Highly economical, the HY4500SEi has 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.

*kVA is based on an assumed load factor of 0.8.

All of our single phase generators have a kVA rating that is higher than the kW. This is because we have assumed the appliances you are going to power have a load factor/power factor of 0.8 - therefore the 'assumed' kVA rating of the load would be higher. This is industry standard and it is usually best to scope the right unit based on the kW.

    On Par with my little 1KW Honda Suitcase - but with LOTS more Power!

    Posted by Dale, Batley on 9th May 2021

    This generator is truly a 5* machine. Starts first time, every time. Quiet whilst running and even under heavy load, instant power delivery on demand, economical on fuel, not too heavy, convenient and easy manoeuvrability due to the extending carry/pull/push handle - I really can't fault it - Nice one Hyundai 5*****!
