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

The HY4500SEi is a compact yet powerful portable inverter generator from Hyundai.

Providing a convenient and cost-effective source of power, this portable generator is perfect for providing power whilst camping or in a caravan away from mains power or for use in a garden workshop.

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.

Caravan and Camping Generator

Powered by the Hyundai HY225E 223cc 4-stroke OHV engine, producing a max output of 4000w / 5kVA and continuous power of 3.8KW / 4kVA, the HY4500SEi camping generator 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.

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

Portable Generator

The compact symmetrical design of this portable generator makes it easy to store and transport in the back of your car or van.

Weighing 50kg, this - combined with the folding front, moulded rear soft-grip handle and heavy-duty rear wheels - makes transportation easy, even across rough or uneven surfaces.

Sine Wave Output 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.

Easy To Use 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.

This petrol inverter generator also comes with 2 remote start keys and 2 manual start keys, allowing you to start your generator without going outside your caravan or motorhome - especially handy if it's raining!

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.

3 Year Warranty

For ultimate peace of mind, this generator is covered by Hyundai's 3 year platinum domestic warranty* / 1 year commercial warranty* (terms apply) with UK parts and service backup to maintain your petrol inverter generator for years to come.

*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.
