Hyundai HY3900Si Digital Inverter Suitcase Generator

*Please be advised that Hyundai Power Products now have an extended lead time and you may not receive them next day. The current delivery time is estimated at 1-2 working days.*

When a 2kW generator is not quite enough for your setup, the next step up matters. The Hyundai HY3900Si delivers 3.3kW / 3300W maximum output and 3kW / 3000W continuous from a 144cc four-stroke engine. That extra headroom means you can run a caravan fridge, charge multiple devices, power lighting and still have capacity left over. The pure sine wave output keeps sensitive electronics safe, while the ECO mode stretches your fuel when full power is not needed. At 21.15kg, it is still portable enough for one person to move.

With 3.0kW continuous output, the HY3900Si handles combinations that smaller generators cannot. Run a fridge, charge your devices and power lighting simultaneously without worrying about overload. Ideal for larger caravan and motorhome setups.

The inverter technology produces stable electricity with low harmonic distortion. Connect laptops, televisions, games consoles and other sensitive electronics with confidence.

When you are drawing less than full load, ECO mode automatically reduces engine speed, reducing noise and giving better fuel economy. This extends the runtime in between refueling.

The HY3900Si features a 16A industrial blue socket for connecting equipment that draws more than a standard connection. The 3-in-1 digital meter lets you monitor output in real time.

Please note that inverter generators are specially designed for leisure use, for weekend getaways, holidays or emergency standby use.

These generators are not suitable for continuous daily use or as an off-grid power supply.

For heavy-duty commercial use, we recommend a conventional 3000rpm petrol generator.
