How do paralleling generators work?

Paralleling 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 synchronization or parallel Able gensets load-sharing 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.

Running generators in parallel or not to parallel diesel generators?

The benefits of parallel generators

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

Replacing gensets in parallel

Greater reliability is offered than by a single generator, if one unit fails, the loads are redistributed among other units in the system. With paralleling generators, this means that the units will have the redundancy necessary to maintain power even if one of the units goes out.

Paralleling 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 synchronization 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, synchronous generators, synchronized generators, synchronizing generators, synchronised generators, generator paralleling, generator paralleling, and generators in parallel operation.

Why parallel? Why not simply get a bigger generator?

There are many reasons why somebody might not need to simply buy a bigger generator. The foremost common reason is once somebody already owns an electrical converter generator then discovers later they have a bit additional power needed. This is often smart to buy a further generator to accommodate the increased power desires instead of abandoning their current setup. what is more, electrical converter generators can be more fuel economical and considerably quieter than a comparable sized open frame generator? This is often a result of a larger 4000-5,000+ watt (non-inverter generators) run at an identical throttle till manually adjusted. Electrical converter generators (even once running in parallel) typically have an eco mode and technology to vary throttle-supported power demand. Thus, there is a way additional economical setup and far more moveable. Lastly, there are many parallel capable generators accessible for purchase that are roughly constant cost as an equivalently power-driven open frame unit. Having 2 generators offers additional flexibility supported power desires AND a possible backup if one were to fail while off the grid. Of course, one unit alone won't run an AC unit, however, the smallest amount would run the fundamentals.

Parallel generators does it harm the Generators?

Running synchronized 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 synchronization is usually solely attainable if the makers are identical like most powerful Able generators are. 

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 in the parallel operation of multiple generators is greater than what is offered by a single generator unit for critical loads. If one unit fails, the critical loads are redistributed among other units in the system on a priority basis. Critical loads that need the highest degree of reliable backup power usually account for only a fraction of the overall power generated by the system. In a parallel system, this means that the most critical elements will have power even if one of the units goes out.

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 the working of the individual generator and have to be in sync with the working of the parallel system which is controlled by the master controller. In traditional, older parallel systems, there is also a lot of electric noise due to the simultaneous operation of multiple controllers. This causes a lot of disturbance and these systems are often predisposed to temporary collapse. Therefore, it requires constant supervision for consistent power supply during power failures, which is an added expense and obstacle to overcome.

Ease of Maintenance and Serviceability

If a generator in the system breaks down or requires maintenance, individual units can be dismantled and serviced without disrupting the functioning of other units. The redundancy inherent in a parallel system provides multiple layers of protection and ensures an uninterrupted supply of power for critical circuits.


Individual units operating in parallel are typically 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
