Can You Safely Run Two Generators Together

Usually, small residential houses have a single portable generator that has a low capacity. You can power up your lights and fans on these portable generators. Portable generators are easy and handy to use, they occupy less space and have low noise.

But what if you want to run your AC, fridge, and other heavy appliances on generators without breaking the bank? Don’t worry! In this article, we will discuss how we can parallel two generators of the same capacity to run our heavy-duty appliances.

The science behind paralleling two generators is that the total capacity will increase and the electricity produced by these generators will be enough to run AC and fridge etc. This is very easy and we gonna discuss it in detail.

Can You Parallel Different Brand Generators?

Yes, you can parallel two generators without worrying about their sizes or brands. The only thing that is considered essential is that both have the compatibility to connect in parallel. Moreover, both should have matching parallel ports to connect to each other.

Care must be taken if you are connecting paralleling two different-size generators. As in the parallel connection, the current is drawn from both generators equally, and if one has more capacity than the other, there are chances that the generator will stop working due to overloading.

However, avoid paralleling two non-parallel generators due to a lot of technical reasons and it is not an easy task to do so.

How Do Parallel Generators Work?

This process is very simple. When two generators are connected parallel, power is drawn from both of the generators equally and through a single connection, it is distributed to all the appliances at your home. The steps are very simple for paralleling, lets’s have a look;

How Do Parallel Generators Work

Step #1

There are some things that must be checked before paralleling two generators otherwise it will prove damaging;

  1. Both generators have the same size
  2. Both generators have the capacity for paralleling
  3. If brands are different check their paralleling ports that must be matched
  4. Both generators have equal frequency

Step #2

In the second step, it’s time to connect the two generators with a parallel kit that must be designed specifically for this. I will suggest that if you don’t have the proper knowledge of how to parallel two generators then take the help of some professional to make this task easier and more accurate for you.

This is a highly crucial step. You can also consult the owner’s manual where guidance is given about paralleling.

Can You Parallel Two Different Inverter Generators?

Yes, you can parallel two different inverter generators but all you need is a compelling and planned setup. Paralleling the generators is an option if you require more power than one can provide.

When you say you’re “paralleling two generators,” it means that you are connecting two generators to double the electricity supply. As we have discussed earlier, this is a very simple and easy step but care must be taken on every step.

You can generate more current by employing this strategy. It is the best option for people who love to visit the world. It helps them at their campsite locations too.

As long as the voltage and frequency are the same where the connection is made, you can connect up to any generator, regardless of its size or brand. (with care)

Benefits of Running Parallel Generators

There are many benefits of running parallel generators, some of which are given below;

Increases the generator Electrical capacity

Suppose you have a small factory that generates very little revenue as you have just started it. You need a single portable generator with low electrical capacity to fulfill your demand.

But as time passes and your business flourish, your electrical need may increase. In that case, in spite of buying a new big generator that demands a large expense, you can make your small generator useful by paralleling a new generator of the same capacity. This will saves a lot of your money and you can increase the capacity of your generator.

Increase generator Efficiency

You know that the electrical load doesn’t remain the same every time, it always fluctuates which can cause damage to your expensive appliances. Due to these fluctuations, the efficiency of the single larger generator may be lower as the system might get underloaded or overloaded. Moreover, it will also increase fuel expenses and it requires maintenance off and on.

However, in a paralleled system generators keep on running at the ideal capacity of 75–80% which results in an increase in generator efficiency, lowers fuel consumption, and is also cost-effective. Fluctuations in capacity are handled exceedingly effectively by this configuration.

Increase generator Efficiency

Adds Redundancy

Suppose, your generator stops working because of fluctuations or some other reasons, the paralleling system will now distribute the load among other generators without interrupting the electrical supply. All this is because the most essential emergency components still have power because of redundancy.

The creation of redundancy and the maintenance of the power supply are the primary reasons that make parallel generators reliable and efficient.

Paralleled generator systems are better than ever thanks to recent technological advancements. That’s why they are considered the priority among business systems. Additionally, these technologies are currently widely accessible, and quite simple to handle with a little upfront cost.

Lower Expense

As we have discussed that parallel generators are cost-effective now let us see how? This parallel system is also able to work when they are undergoing maintenance. As multiple generators are connected in the team so the load is shifted to other generators without interpreting the power supply.

This might reduce the requirement for temporary tools during maintenance or remove the danger of entirely turning off the backup power system thus saving a lot of money. Moreover, its maintenance is very easy.

What to look for using two parallel generators?

While using two  parallel generators always check;

  1. Both generators have the same size
  2. Both generators have the capacity for paralleling
  3. If brands are different check their paralleling ports that must be matched
  4. Both generators have equal frequency
  5. Generators must be of high quality

Can You Use Two Generators Together – FAQs

What will happen if two generators are connected to each other?
When two generators are connected to each other, the power supply will increase which will be enough for you to run heavy appliances pon this load.
Can you run different size generators in parallel?
Yes, you can run different generators in parallel if they have the same frequency, same size, and matching paralleling ports.
What is needed for a generator to parallel with another generator?
All you need is a paralleling port or check the paralleling capability of the generators. If both have the capacity to paralleling they are good to go.



You may enjoy all the advantages of inverters with parallel generators without being concerned about running out of electricity. You can be sure that there will be enough dependable, clean power available to power your daily activities without lying heavy on your pockets.
