Synchronised 660kVA-2200kVA

Australia's Synchronised Generators Specialists

Synchronized generators or parallel generators can be 2 to 32 or more generators working as 1. Some Able's Synchronised power range is in stock and is already synchronized readily to go anytime. All our ABLE Generators 137 kVA and above are synchronised-ready.

The advantages of Synchronised Generators are :

  • Built-in Redundancy in the unlikely event of generator failure - The other Generators keep the site powered.
  • Convenient Servicing while the other Generators keep your site running giving no downtime.
  • Flexible System for varying power requirements - Increase or Reduce your number of Generators easily.
  • Underloading of Generators is Limited due to Flexible Generator Usage Options.
  • Lower Initial Investment Cost Savings - Sometimes Can be Cheaper than Purchasing 1 Large Generator.
  • Fuel Usage is Similar or Better to Single Generator Systems.
  • Can be set up for 90% Plug & Play Operation.
  • Any Combination of Generators can be Used in Parallel.
  • All Generators can be Monitored and Controlled off-site via the Internet.

How do paralleled generators work?

Paralleling or synchronising generators is a method of connecting one or more generators together with the lead machine turning on and off generators as extra power is needed, so if you had five 100 kVA generators connected that would be like having one 500 kVA generator, having synchronised generators is beneficial in saving on fuel costs and machine wear and tear.

Parallel Load Sharing Generators

Using generator synchronisation or parallel generators as a Power Management System has many benefits, like saving on fuel costs, equipment replacement can be done easily with a power disruption, and improved flexibility with maintenance.

The benefits of paralleling generators

Synchronised generators have always been a significantly better choice than a single large generator. Up to now using generator load sharing system or running parallel generators has been limited to large projects like mining or  hospitals because of the higher cost, space, and level of complexity to set up and maintain.
Able Sales with their use of specialised digital control systems have now become cheaper and easier to operate. So, what are the benefits of running generators in generator load sharing?

Greater reliability than a single generator, if one unit fails, the load is shared among other units in the system.

Generator Load Sharing Expandability

Parallel diesel generators can match your load requirements as your power needs fluctuate, it is often difficult to accurately project increases in load and adequately plan for anticipated additional requirements. If the load on a single generator is too light it will reduce the life of that machine but with Parallel Generators, it will switch off unnecessary machines. On the other hand, if load projections were too small, you will be left without reliable power or may have to resort to expensive upgrades, or purchasing another unit altogether. By using synchronised generators,

Paralleling or generator synchronisation is easier to allow for variations in load without overrunning your budget or piling up expensive gensets that rarely get used.
This type of generator setup is also known as load sharing in parallel generators, load sharing generators, synchronised generators, synchronising generators, synchronised generators, generator paralleling, and generators in parallel operation.

Why opt for paralleled generators and not simply get a bigger generator?

There are several reasons why one might opt for generator load sharing instead of simply getting a bigger generator:

Flexibility: Paralleling generators allows for greater flexibility in terms of power output. If you have a single large generator, you are limited to the power output of that generator. However, with generator load sharing, you can add or remove generators as needed to meet changing power demands. This can be particularly useful in situations where power demands vary widely or are unpredictable.

Cost: In many cases, paralleling smaller generators can be more cost-effective than purchasing a single large generator. Smaller generators are often less expensive, and can be more easily transported and installed than larger generators. Additionally, if one of the paralleled generators fails or needs maintenance, you can simply take it offline without losing all power, whereas with a single large generator, any downtime would result in a complete loss of power.

Efficiency: Paralleling generators can also be more efficient than relying on a single large generator. By using multiple smaller generators, you can run only the generators that are needed to meet current power demands. This can help reduce fuel consumption and lower operating costs.

Redundancy: Paralleling generators can provide redundancy and backup power in case of generator failure or maintenance. By having multiple generators, you can ensure that there is always a backup power source available in case of emergency.

Does Paralleling generators harm the generators?

Running synchronised generators or Generator Load Sharing isn't a harmful exercise as long as they're 2 generators that are designed to be run in this manner. Moreover, most generators need a specific parallel cable to create this work. The explanation for this can be that every generator has its own laptop within. They're not designed to figure well together among totally different makers. This synchronisation is usually solely attainable if the makers are identical like most powerful Able generators.

Paralleling Issues

The main problem with generators is the workload, generators need a hard life, preferably a workload running at 75% and less than 30% will cause glazing or wet stacking and if the demand is too much the controller will switch it off and this is where the beauty of running 2 generators in sync comes in. The main problem with most home generators is that they just don’t get worked or used enough. Most people only use their generators occasionally. Unfortunately, when they put them into storage, they usually leave untreated gasoline in the tank. Old fuel left in a generator’s tank will make your life a living nightmare in just a matter of months, untreated gasoline can leave a thick gooey varnish-like residue in the fuel system, Diesel lasts longer but still has age issues. As you can see, running generators in parallel has some clear advantages and should be a consideration for any company looking to get high level, redundant, backup power. However, there are costs and other considerations to take into account and because of the complexity involved, technical expertise is an absolute must to design and install a properly configured parallel system.

More on reliability

The reliability of parallel generators is much greater than a single generator. If one unit fails, the load is redistributed among other units in the system on a priority basis. Most synchronised generator set ups can handle at least one generator failure without causing a disaster amongst the others.

Able Sales Genset Controller

Able Sales uses only the best controller for syncing and all generators over 35kVA can be synchronised. The controller is installed for checking the parameters of the engine and the alternators of each unit in the system. Load control and scheduling generators to go on/off. The controller checks for proper synchronization, load and voltage balance, and reverse power functions. In traditional parallel operating systems, each of the generators has its own controller in addition to a master controller that governs the combined system.

Each of the controllers has to be installed so they control individual generators and have to be in sync with the master controller. In traditional, older parallel systems, there is also a lot of electric noise this causes a lot of disturbance and these systems often collapse. Therefore, it required constant supervision which is an added expense 
and obstacles to overcome.

Ease of Maintenance

If a generator in the system breaks down or requires a service like replacing the oil and filters, individual units can be worked on without disrupting the others. 


Individual units operating in parallel typically have smaller capacities. The engines used in these generators are usually industrial or high-quality engines designed with advanced manufacturing technology that gives them a high degree of reliability and low cost of generation per unit of power. Able Sales can sync up to and including 1100 kVA
