High-output 5.5kW inverter power with electric start for large motorhomes and off-grid leisure
Larger motorhomes, twin-axle caravans and off-grid glamping setups can draw more power than a mid-range generator can comfortably handle. The Hyundai HY6250SEi delivers 5.5kW / 5500W maximum output and 5kW / 5000W continuous, giving you the headroom to run a fridge, microwave, lighting and entertainment system without worrying about overload. The 223cc four-stroke engine starts at the turn of a key thanks to the electric start system, and the 11L tank provides a long run time. Despite the output, the inverter technology still produces pure sine wave electricity, keeping your sensitive electronics safe alongside heavier loads.
Key Benefits
Electric start for instant, reliable ignition
No pulling required. The HY6250SEi features electric start, so you turn the key and the 223cc engine fires up. This is particularly useful in cold weather or for users who find recoil starting difficult. A recoil backup is also fitted.
5kW continuous output for larger leisure setups
With 5.0kW continuous power, the HY6250SEi can run combinations of appliances that smaller inverter generators cannot handle. Power a fridge, microwave, air conditioning unit, lighting and entertainment system at the same time. The 5.5kW peak output handles motor startup surges.
Pure sine wave output despite the high wattage
Even at this output level, the inverter produces clean sine wave power. You can safely connect sensitive electronics alongside heavier loads without risking damage from unstable current.
Large 11L tank for extended running
The 11L fuel tank gives you up to 21.7 hours at light load (10%) and 6 hours at 50% load. ECO mode extends this further by reducing engine speed when demand drops, reducing noise and giving better fuel economy. The 3-in-1 digital meter helps you monitor output and plan refuelling.
Who Is This For?
This generator is ideal for:
- Large motorhome owners with high power demands
- Glamping and off-grid cabin setups needing serious portable power
- Boat owners and marina users with larger power requirements
- Motorsport & Equestrian vans and trucks
- Allotment holders and rural property owners needing seasonal off-grid power
- Anyone with a large off-grid leisure setup who needs to run multiple or larger appliances at once
This generator is NOT ideal for:
- Lightweight camping where a smaller, quieter unit would be more practical — consider the HY2350Si
- All-day continuous commercial use — this is a seasonal leisure generator, not designed for constant daily operation
