Can conventional generators be connected in a series?
Yes, you can do that.
However, the process is not as simple as it may seem and requires a number of subtle steps.
In this piece, I'll explain the rationale behind paralleling a generator, as well as the most efficient means of linking together several generators to produce a single, continuous output.
It is possible to double the output power by connecting two parallel-running generators and operating them in tandem.
As a general rule, it's simpler to link together generators of the same brand or of the same output power.
Connecting generators in parallel is considerably easier if the generators themselves are parallel-capable; however, if your generator is not serial-enabled, the process will alter slightly.
You may think there are complicated rules behind load sharing. As soon as you compare the various load-sharing strategies, you will see how easy it is.
The following are examples of load sharing in its different forms:
This method of load sharing is straight forward, and involves the reduction of either the alternator voltage or the engine speed. This is made possible by the output range having a constant fraction.
Isochronous control systems provide load data measurement. They are also able to determine the load percentage of the generator. While kilowatts (kW) measure active power, kilovolt-ampere-seconds (kVAR) measure reactive power.
The control systems determine the loads in order to distribute the power demand evenly across the available generators.
A single-board paralleling controller makes it easy to add more generators as you scale up your system. Furthermore, these controllers permit simple system upgrades. In addition, generators that are paralleled can be used under any load.
The ability to do cross-current correction is dependent on there being no voltage drop between paralleled generators. As a result, if you wish to maximize alternator load sharing, you must employ identical voltage regulators.
Adjusting the outputs of both generators to the same value is required. In order to maintain a consistent output, it is important to monitor the bus voltage or generator speeds, if possible.
As a result, we won't have to rely on just one overworked generator.
Overloading the generator and distribution system can occur when there is a frequency mismatch between the generator and the associated systems, a phenomenon known as motoring.
Whether in a user manual or online, most companies will detail which alternators work with their products.
Having two generators with nearly comparable engine capacities, or the flexibility to adjust capacities to the same kilowatt value, can considerably improve efficiency.
Paralleling non-inverter generators from various manufacturers may need the usage of adapter cables.
There are bundled sets available from each manufacturer, or you might consider purchasing separate adapters.
It is possible to safely parallel non-inverter generators if you carefully adhere to the instructions and verify that the system is functioning optimally with the load split between the two generators.
The vast majority of you cannot survive without constant access to electricity. Electricity powers the vast majority of your household gadgets. In the event of a blackout, you should be prepared with alternative power sources.
Consider your emergency power needs before purchasing a generator. Keeping an appliance running may require a tiny backup power supply. However, bigger machines may need more juice to stay functioning.
If the amount of power you need varies a lot or you like smaller generators while camping but still want it to be useful at home, then in this case, parallel generators are the optimal solution.
The justification for using generators in parallel is as follows.
In case of a failure in one of your paralleled generators, the others will take over automatically. That's good news because it means your appliances should continue working normally. Be wary about putting too much strain on the alternators.
Larger space requirements apply to higher-rated generators. If you just have one massive generator, things could get tricky.
Smaller generators are easy to maintain, and you could service them at different times ensuring you maintain electrical backup.
Generator paralleling can only function at their optimal levels if certain restrictions and safeguards are observed.
The generator must be set up at this time, running at synchronous speed while the voltages are balanced, in order to be connected in parallel.
The phase sequence of the oncoming generator must also coincide with the phase difference of the operating system.
Easily verify this by switching the ends of two generators that are connected to a small induction motor.
Both generators' phase sequences will be identical if the motor always rotates in the same direction.
Two of the generator's wires can be swapped to alter the phase order if the motor rotates in the opposite way.
The sequence can also be monitored in a less complex way by using a sequencing device, which can be electrical or electromagnetic and works on the same principles as the engine described above.
Having a synchroscope, which is a device used to show that the generators are in sync. It is also the simplest technique because it can be used to calculate the phase difference between the two systems for any given phase.
Both electronic and analogue needles are on the product.
Two generators, of varying sizes and brands, can be used in a parallel arrangement. However it is naturally easier if they are the same brand and the same size. It is just easier to work on them in the same way with the same set up.
Different brands will be different shapes and might require different tools, but parallel kits should work universally.
Most parallel kits consist of six terminals. Two of the lines are ground leads that go to the bottom of the generator, while the other four are live wires.
You can still use this method even if none of your generators support parallel processing officially, but nearly all generators can be joined, but you might void the warranty if something goes wrong.
To begin, link the first generator output pin to the other generator's input source. Just hook up the second generator to whatever it is that needs power.
Start the first generator. Then start the second generator after a couple of minutes or after you are sure the first generator has no running problems. Following these instructions, users can properly couple two generators of varying sizes and brands.
The use of parallel generators has various benefits. You may, however, still be able to identify some problems.
When utilizing parallel generators, you may encounter the following problems:
Many organizations and households use parallel generators instead of singular generators. That's because setting up a set of parallel generators is a lot less complicated than setting up a set of separate generators or buying one large one.
Series generators are more costly with minimal benefits. It is far more beneficial and economical to use generators that operate in parallel.
In addition, you can get adequate power from either a parallel or a series generator setup. There is no need to go into debt. To ensure you receive all the benefits you need at more reasonable prices, paralleling may be the best option.
Larger generators might not provide enough power even in theory. It's possible that upgrading to a more powerful generator won't be worth it.
You should only put your money into safe investments. In that case, experts recommend connecting many generators simultaneously.
Larger generators wouldn't offer any advantages that smaller, parallel generators wouldn't. If your massive generator goes down, everything will have to stop. But if you set up parallel generators, you can ensure a steady flow of electricity.
One potential problem is that huge generators are not easily transportable. They're a hefty weight to carry about. To put it another way, you clearly can't carry them around with you.
It is not difficult to relocate a tiny generator from one place to another. You may take it with you anywhere. If you find yourself in need of electricity while having fun in the great outdoors, you can always rely on your parallel generators.
Of course the easiest way to parallel generators is to buy inverter generators which are designed for this purpose.
Here are some of the best:
For starters, we'll look at Generac, which is widely recognised as the best generator brand and one of the most well-liked inverter generator choices because of its dependability.
Because of its innovative design, Generac's converter generator is far quieter than standard models. A 212cc engine, together with PowerRush Advanced Technology, allows this generator to successfully produce 3500 starting watts and 3000 running watts. The Generac GP3500iO can also run in tandem with another similar device.
At a 25% load, this inverter generator's 2.37-gallon gas tank allows for about 11 hours of operation. There are a pair of 120V 20A outlets on the unit's back, as well as a 120V 30A twist-lock plug. Moreover, two 5V USB outlets are included. The design is quite lightweight and functional. A three-year guarantee is included from Generac as well.
The WEN 56200i Portable Inverter Generator has a rated output of 1600 watts and a surge power of 2000 watts, making it suitable for use during power outages, camping trips, and other outdoor gatherings.
Thanks to the pure energy it produces, this gadget can be used around sensitive gadgets like computers, TVs, phones, and tablets without risk.
The device has two 120V three-pronged plugs, a 5V USB port, and a 12V DC port. All of your electronic devices and appliances may be plugged in right here.
If you're looking for a portable option, this one really is, unlike many others out there. Because of how light it is, transporting it shouldn't be too difficult. It has a quiet operation that won't wake the forest or annoy your neighbors. It also features an eco-mode for producing only eco-friendly energy.
A basic interface can be accessed. This generator is straightforward enough for non-specialists to use. Everyone can simply take it up and start employing it right away.
Since Westinghouse is a popular name in the premium market, they are well made and reliable.
The 224cc engine in this premium inverter generator choice provides 4500 watts of starting power and 3700 watts of constant operating power, so its strength is not in question. It uses relatively little fuel, has a low noise output (only 52 decibels), yet can produce a lot of force.
This generator boasts a massive fuel tank of 3.4 gallons, providing it with enough energy to operate for around 18 hours without refueling. In terms of extras, it has a 5-20R 120V Duplex Household Outlet, an RV-Ready Tt-30R 30 Amp Outlet, and two USB Ports on the back, all of which can be used in parallel.
When connecting two generators, one of the determining elements is the total capacity of the machines being paralleled.
If one generator is noticeably larger than the other, the combined output of the two will be reduced.
So, yes you can parallel non inverter generators, but I would recommend buying inverter generators to make your life easier.
