Premium Commodore | Off Grid Diesel Generator | 27.5KVA Three Phase | 2 Wire Auto Start


SKU: HD8000SDG-1-1-1-1 Categories: ,


Here at Commodore we are pedantic about quality and reliability, when it comes to off grid power there is nothing more frustrating than having issues caused by lower quality equipment. Which is why our smurf blue Commodore generators are built to specification not to price, high quality equipment works out substantially cheaper in the long run.

All of our Smurf blue diesel models are standard with an advanced Deep Sea controller pre configured for 2 wire auto start, making them perfect for off grid backup and emergency power. Featuring electric start with a heavy duty starter motor, reliable 1500 RPM 3 cylinder engine, and large output terminals for hard-wiring to your switchboard. Ours employ a warm up and cool down cycle managed by the deep sea controller to further look after the engine. Also supplied with a 10W solar panel trickle charger to keep your generator battery topped up & ready to rock n roll whenever you need it.

This unit will deliver a maximum AC output of 27.5kVA/22KW (@ PF0.8) or 25kVA/20KW continuously. A water cooled engine means that it can run for extended periods of time whereas air cooled generators can be run for approximately 4 hours at one time.

An Automatic Transfer Switch (ATS) is available which allows this generator to be used for automatic mains power failure protection. If the mains power fails, the ATS will disconnect from the mains then start the generator to safely switch over & supply power to your property. Once the mains power is restored, the ATS will shut down the generator and re-connect your property to the mains power grid. ATS is available for grid switch over. Please contact us for more information.


– A lot of other generators on the market are running a smaller engine, for example a 10kVa 2 cylinder revving to 3000rpm vs our 9kVa 3 cylinder revving to 1500rpm. Running with less cylinders and at a higher RPM means they are working much harder, and likely to have a shorter life span. It’s a bit like having a Hyundai Getz and a Landcruiser both towing a 1.5 tonne trailer, they’ll both physically be able to tow the trailer however one will be able to tow that trailer for a hell of a lot longer than the other.

– Another feature of the lower 1500rpm is that there is less noise, less vibration, less wear and tear, meaning more reliably and a steadier output power. Ours also have a foam padded sound proofing inside the enclosure which keeps them quieter again.

– A large majority of generators are not set up for off grid as they don’t have two wire auto start, which means the generator will not kick in automatically to charge your batteries and/or provide direct back up to your house. With some generators it is impossible to add a two wire start onto it afterwards as the controller isn’t designed to do so, other generators you can add a two wire auto start later but it’s difficult and expensive to do.
