Description

10kW of single-phase diesel power for a large home or small business. The Hyundai DHY12500SE is a twin-cylinder standby generator in a sound-attenuating canopy, with 20 hours of running at half load and an ATS input ready for automatic changeover. It's built for when a small petrol generator simply won't cover the load.

Why buyers choose the DHY12500SE

  • Real standby capacity. 10kW continuous and 11kW maximum on 230V single phase.
  • Long running. The base-mounted tank gives 12 hours at full load, or 20 hours at half load.
  • Automatic standby ready. An ATS input lets it work with Hyundai's automatic transfer switch, so it can start itself in a power cut.
  • Twin-cylinder diesel. The 20hp air-cooled HY290F engine holds its speed steadily as heavy loads come on.
  • High-current outlets. One 63A and one 32A 230V socket, with overload breakers and an emergency stop.
  • Quieter canopy. The sound-attenuating enclosure brings it down to 68 dB(A) at 7m.

Is it right for you?

Ideal for: large homes with heavy loads, small commercial units, farms and rural businesses wanting dependable single-phase standby.

Look elsewhere if: you have three-phase equipment, in which case see our three-phase generators. If 5 to 6kW would cover your essentials, our smaller diesel generators are easier to site and move.

What will it run?

Plan around the 10kW continuous output, and have an electrician survey your actual load first. The 11kW maximum is for short bursts, such as a motor starting. A 32A socket supplies up to about 7.4kW, so use the 63A outlet for the full output.

Appliance Typical running watts
Fridge freezer (higher start-up draw) 150 to 300W
Central heating pump and boiler electrics 100 to 200W
Lighting for a whole property 200 to 500W
Microwave (800W cooking power) around 1,200W
Kettle 2,500 to 3,000W
Immersion heater 3,000W
Electric shower 8,500W: only with little else on. Showers over about 9.5kW are too much

Example: fridge freezer 200W + boiler electrics 150W + lights 300W + TV and broadband 200W + kettle 3,000W + microwave 1,200W + immersion heater 3,000W comes to about 8,050W, which leaves around 1,950W in hand. Check the rating plates on your own appliances, as figures vary.

Connecting it for standby

This generator should be connected by a qualified electrician. Use a manual changeover switch, or Hyundai's automatic transfer switch package with the ATS input for automatic start. Either way, the generator and the mains must never be connected together, and it must never be fed through a socket.

Getting it running

  • Choose a level, solid base outdoors with clear air around the canopy. At 295kg, it moves only on flat, firm ground on its castors, two of which have brakes.
  • Add 2.25 litres of SAE 15W-40 oil before the first start and check the level.
  • Fill with clean diesel and check that the battery is connected.
  • Hyundai's schedule asks for the first oil change after one month or 20 hours, then every 3 months or 100 hours, along with air and fuel filter service.
  • Start it regularly under load if it's on standby, so that it's ready when needed.

Delivery note: at 295kg, you'll need a way to unload it safely, so please check access before ordering. Hyundai stock can take 1 to 3 working days to dispatch. Contact us before ordering if you need one by a certain date.

FAQs

Will it start automatically in a power cut? Not on its own. It has an ATS input, and needs an automatic transfer switch installed to do this. Ask us about the Hyundai ATS package.

Can it run three-phase equipment? No, this is a 230V single-phase generator.

Will it power an electric shower? An 8.5kW shower will run with little else on, but larger showers exceed what it can supply continuously. Have an electrician check your actual load.

Is it really silent? Hyundai calls it silent, but 68 dB(A) at 7m is still clearly audible, so site it away from neighbours.

Not sure it's the right size? Send us your appliance list at sales@generator-uk.co.uk or call 01744 520110, Monday to Friday, 8:30am to 5pm, and we'll help you size it.

Safety: run outdoors only, well away from doors and windows. Generator exhaust contains carbon monoxide. Let the engine cool before refuelling.
