Hyundai DHY12500SE Backup Generator

The DHY12500SE is a diesel single-phase backup generator from Hyundai. Ideal for providing your home or business with reliable backup power when the national grid lets you down, this high-quality diesel genset is able to produce up to 12.5kVA.

This generator’s Hyundai twin cylinder air-cooled engine can produce up to 12.5kVA / 10kW backup power, perfect for your peace of mind that you won’t be without power, wifi and heating during a power cut.

Diesel Generator for Backup Power

Equipped with an AVR alternator, the DHY12500SE backup generator is suitable for powering sensitive electronic equipment in your home or business, such as televisions, games consoles, computers, laptops, and more.

The long run 60L base-mounted fuel tank will give up to 18 hours run time under ¼ load, meaning you won’t need to keep topping it up with fuel as often for fuss-free power.

Diesel generators are ideal for backup applications as sometimes petrol can go stale and prevent a generator working. Our diesel generators also run happily on budget-friendly red diesel, without voiding the warranty and making it cost-effective to refuel.

Quiet and Portable Generator

Thanks to the DHY12500SE’s engine operating at a low noise level within the sound attenuating enclosure, this diesel generator only emits a noise level of 70dB @ 7m whilst operating at a 75% load. This makes this a great option if you’re looking for a quiet standby generator that won’t interrupt you at home or work.

Mounted on 4 wheels, (2 steerings with brake and 2 fixed), it can be easily moved on a flat surface to wherever it is required.

ATS Compatible

For ultimate convenience, the DHY12500SE can be paired with an ATS - Automatic Transfer Switch - system (not included) which will automatically turn on the generator when a loss of power to the property is detected. When power returns from the mains, the ATS module will then safely turn your generator off.

This is ideal for those who need to guarantee constant power - for example, if you run servers or have refrigeration units.

It also has key start and two wire start options available, ideal for standby power in large homes or small businesses in the event of a power failure.

Easy-To-Read Control Panel

The control panel features a digital panel to display volts, hours and frequency. This generator also has 32A and 63amp sockets at 230v mains voltage, an emergency stop button, overload breakers, and a 12v DC output.

3000rpm Generator

3000rpm diesel generators are ideal for use as a standby/backup power in homes and small businesses. They are also suitable for use as standalone power in small workshops, farms or barns - when you need a few hours of power for tools or equipment.

Our 3000rpm gensets can also be used for mobile field repairs. If you work in agriculture or farming, these generators can fit in the back of a pick-up, and will run power tools and welders up to 150Amp to keep your farm machinery mobile and running without needing to take it back to the yard.

For more frequent use, or if running for extended periods of time every day (prime power) you should purchase a 1500rpm water-cooled, slow running generator that has a much longer lifespan.

Generator kVA Ratings

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.
