Diesel, Bio-Gas & Petrol Silenced Generators

If you do NOT have an Automatic Mains Failure (AMF) switch fitted to your premises, you MUST first turn OFF all mains fuse's, and preferably remove them, even if only testing your generator, removing the main fuses should be done when switched OFF, ONLY once that is done, then it is safe to test your equipment.  Then, people working on the state grid will not be in DANGER from electrocution from your tests!

Why purchase a Diesel Generator ?

To Blackout-proof your premises OR to become Energy Independent !

However, we advise people to First purchase Energy Storage, before a modern Gen-Set !

You might be thinking why ? The answer is simple, Batteries cost around $500kWh and SAVE energy that would be wasted or sold to the Retailers, where Generators cost from $300kW and Cost money to Operate, however a gen-set will also be Charging the batteries, reducing the running cost (...see FREE Fuel section below)


So, Assuming you already have Solar & Grid Connected. It is a lot Cheaper & Smarter to Store the energy you harvest than sell it for a feed-in tarrif, Off-Grid people know this & most already have Energy storage.

If you are Grid connected and Don't have energy storage, the Generator Fuel Cost or the Grid energy Rate costs is 300% more than any FIT rebate.

With Energy storage, a Generator will ONLY need to start when your battery energy gets low, and that will usually be for a short time early in the morning.  Energy storage only captures what would normally be waster energy !

A Hybrid inverter with an 'Auto Generator Start' (AGS) function, would ONLY be needed to charge or top-up your Battery bank to a pre-programmed time.

Diesel generators are cheap to purchase and operate, you don't actually need Solar, Aqua or Wind generation if you have a Diesel generator and Battery bank.  However a battery bank is the critical investment with all Off-Grid Solar & Gen-Set System, as mentioned above, it allows you to operate the Generator for short periods, providing maintenance free operation for many years, other than oil and filter changes.

FACT: In 2017 most Australian customers paid over 28 c/kWh for Electricity 24/7 (excluding off-peak), those that receive the measly solar feed-in Tariff (Rebate) of ONLY 6~8 c/kWh for there excess power - get ripped off after-sunset, as they get slugged with the full electricity rate of 28 c/kWh, that's over 300% more than the feed-in Tariff they receive!  So, who is really been taken for a ride ?

If you have Energy storage & Hybrid inverter, this is where a Diesel generator comes into play, as the auto-start switching gear will start & stop a gen-set as you program it, NOW you have the option to disconnect from the state grid, and save you the $320 year ($80 quarter) Connection Fee !

This 3.5kW Gen-set is super quiet (58dB), and weighs just 38kg, this unit will charge any battery bank and accomplish the same power production in approx. 1~4 hours depending on your battery bank size, and your daily kW consumption, the only cost will be Fuel.


A Diesel Generator engine can run on Clean Process Waste Vegetable Oil (WVO) as fuel.

A Petrol Generator engine can Run perfectly on Bio-Gas, harvested FREE from a small 3m3 organic Bio-Digester, & in-turn the bio-gas can be compressed into any LPG tank for better storage.

  3. This calculator Instantly evaluates Independent Power Grid-v-State Grid Cost.

These are the Generators we recommend you use, rarely will a modern Micro Grid need larger than a 10kWh Gen-set.

We ONLY recommend a Generator be used for these reasons;

  1. If your Battery voltage warns of Low voltage or if all other form of generation fails !
  2. If your Generator runs on FREE GREEN FUELS from;
    1. BioGas Harvested from a Bio-Digester, to be used in 4stroke Gen-Set Petrol engines (read more on Bio-Gas Digester’s).
    2. Waste Vegetable Oil to replace commercial Petrochemical Diesel, has Less Pollution!
  3. If used with Battery Storage: A small 3.5kWh Generator should Not need to operate for more than an hour or so at a time, and that would usually only be early in the morning or after sustained bad weather, and other harvesting like Wind & Solar has stopped.

Be smart and safe, install Automatic Mains Failure (AMF) switch gear:

An Automatic Mains Failure (AMF) switch is designed to automatically start your generator in the event of mains power failure or low battery bank voltage, and to automatically shut down the generator when the mains/battery power is restored.

Features of a good synchronised AMF panel are:

  • Load Manager, Reverse power protection, Earth fault, Auto manual synchronisation, Volt meter, Frequency meter, All should comes in a single panel.
  • Automatic start and stop of the generator and changeover the EB/generator lines.
  • Auto/manual selector is available.
  • Auto delay in start of Gen-Set.
  • Gen-Set stop with delay of 3 minutes.
  • Alarm for fail to start.
  • 4ST switch control for healthy start and stop of Gen-Set.
  • Manual start & stop switch.
  • Available with emergency stop switch.
  • Auto Low Lube Oil Pressure (LLOP), High Water Temperature (HWT) & Low Fuel (LF) Sensors-Relay protections.
  • Control wires and safety sensors according to their generators’ standard.
  • Checklist to find the fault and to correct.

Automatic Transfer Switch (ATS):

An ATS disconnects the home/business from the power grid when the generator starts.  A cheap residential, single phase ATS mains board mounted switch/system costs upwards of $150, a small price to pay for a first level of safety, these should be installed by a licensed electrician!

Safety wise an advanced Transfer Switch (ATS), provides automatic switching of your premises from Solar, Battery, generator or to state grid supply and back again.

Using LPG, CNG, LNG as Fuel for Generators:

LPG, CNG are all clean dry fuels, and produce less Greenhouse gas than Diesel or Petrol.

What’s the difference between LPG, CNG, LNG, and Hydrogen?

Can you convert a 60 Hz generator to 50 Hz?

In general, most commercial generators can be converted from 60 Hz to 50 Hz. The general rule of thumb is 60 Hz machines run at 1800 Rpm and 50 Hz generators run at 1500 Rpm. With most generators changing the frequency will only require turning down the rpm’s of the engine. In some cases, parts may have to be replaced or further modifications made.

How do I determine what size Generator I need?

Getting a generator that can handle all your power generation needs is one of the most critical aspects of the purchasing decision.  Whether you are interested in prime or standby power, if your new generator can't meet your specific requirements then it simply won't be doing anyone any good because it can put undue stress on the unit and even damage some of the devices connected to it.  Determining exactly what size of generator to get is often difficult and involves a number of factors and considerations.  To get more detailed information on this subject, please use our expanded Calculator on Sizing a Generator

Utility transformers:

 Can increase a Generators 240volts of electrical up to thousands of volts, which is more than enough to kill a utility line person making outage repairs kilometres away, and could also cause extensive damage to utility equipment, home appliances and your generator etc.

HISTORY of the Diesel engine:

History shows that the invention of the Diesel engine was not based solely on one man's idea, but was the culmination of many different ideas that were developed over time.

In 1806, Claude and Nicéphore Niépce (brothers) developed the first known internal combustion engine, that later was successfully operated on pulverulent solid fuel (coal dust), as far as we know there is currently only one of these Coal Dust engines operational in the world, and is located in a museum in Australia.

In 1885, the English inventor Herbert Akroyd Stuart began investigating the possibility of using paraffin oil (very similar to modern-day diesel) for an engine.

In 1891, it is reported that Herbert Akroyd Stuart built an internal combustion engine that operated on heavy fuel oil.

In 1892, Akroyd Stuart patented a water-jacketed vaporizer to allow compression ratios to be increased but primarily to reduce auto-ignition problems at higher loads and compression ratios. In the same year, Thomas Henry Barton at Hornsbys built a working high-compression version for experimental purposes, whereby the vaporizer was replaced with a cylinder head, therefore not relying on air being preheated, but by combustion through higher compression ratios. It ran for six hours—the first time automatic ignition was produced by compression alone, however such a claim is not substantiated by any source and since until 1907 hot-bulb engines were supposed to be charged with fuel at the intake stroke, although separately from air, such an engine would have been prone to failure, poor performance or extreme malfunctioning due to pre-ignition.[citation needed] [21]

Herbert Akroyd Stuart was a pioneer in developing compression ignition aided by retained heat of combustion in the bulb, Rudolf Diesel however, was subsequently credited with the true compression ignition engine relying solely on heat of compression and not any other form of retained heat. Higher compression and thermal efficiency along with injection timing of fuel and vaporization of fuel through injection system and not by heated surface is what distinguishes Diesel's patent of 3,500 kilopascals (508 psi).

In 1892, Diesel received patents in Germany, Switzerland, the United Kingdom and the United States for "Method of and Apparatus for Converting Heat into Work".[22] In 1893, he described a "slow-combustion engine" that first compressed air thereby raising its temperature above the igniting-point of the fuel, then gradually introducing fuel while letting the mixture expand "against resistance sufficiently to prevent an essential increase of temperature and pressure", then cutting off fuel and "expanding without transfer of heat".[citation needed] In 1894 and 1895, he filed patents and addenda in various countries for his Diesel engine; the first patents were issued in Spain (No. 16,654), France (No. 243,531) and Belgium (No. 113,139) in December 1894, and in Germany (No. 86,633) in 1895 and the United States (No. 608,845) in 1898.[23] He operated his first successful engine in 1897.[24]

On February 17, 1894, the redesigned engine ran for 88 revolutions - one minute; with this news, Maschinefabrik Augsburg's stock rose by 30%, indicative of the tremendous anticipated demands for a more efficient engine. In 1896, Diesel rushed to have a prototype running, in order to maintain the patent. The first engine ready for testing was built on December 31, 1896; a much different engine than the one they had started with. In 1897, between deal signing, and brainstorming episodes they succeed, the engine runs; 16.93 kW with an efficiency of 16.6%, he is granted the patent. By 1898, Diesel had become a millionaire. His engines were used to power pipelines, electric and water plants, automobiles and trucks, and marine craft. They were soon to be used in mines, oil fields, factories, and transoceanic shipping.[25]
