How to Parallel Generators? (Installation, Problems and FAQs)

Generators are a great way to produce electricity for your home or office. But did you know that you can also use parallel generators to increase the amount of power you produce? Here is how to parallel generators.

Best generators can also be paralleled to increase power during the day and at night when there’s more demand for electricity in most homes or businesses.

How you choose to parallel generators depends on whether you want to use them together all the time or just during emergencies.

What are Paralleling Generators?

 

There are many reasons why someone wants to parallel generators.

  • Many people parallel generators to provide temporary power for more people or other purposes in an outage. Generators need repair, and a second generator can be connected and used until the first generator is repaired.
  • Besides removing one from service, you could use parallel as a way to increase power in your home. If you have two smaller units, it’s also possible that it may be less expensive than one big unit.
  • Lastly, it may be cheaper for larger facilities such as hospitals or schools that have multiple generators onsite and only need them during emergencies before shutting down again throughout the day, like normal power sources provide 24/7 coverage.

Besides having regular maintenance done on your generator, adding a second one eliminates the downtime that is created by such maintenance.

There are different ways in which generators can be connected to each other.

They can either be wired together with cables and then plugged into a single circuit or used independently in parallel.


What is Parallel Wiring?

Parallel wiring is when two or more appliances or sources of power, such as outlets, fuses, batteries, and lights, are connected to share a single circuit.

This is important to note because if there were a problem with one of the appliances or sources, then the others would also be affected, which increases risk.

How Parallel Wiring Works for Generators?

Parallel wiring works only for those generators which are parallel compatible.

The simplest way is to have two separate circuits where all appliances are wired together on one circuit using the same outlet, but this only works if you don’t want to parallel more than two generators.

Parallel wiring is usually used with appliances plugged into a single circuit or pathway because it’s more cost-effective and easier to maintain onsite without spending more money on equipment.

However, you can still connect multiple appliances into separate circuits using series wiring, but it’s less safe since one problem in the system can affect all appliances at once.

This is why generator parallel kits are not recommended for this type of connection.

What are Combiner Plugs?

Generators are connected using special cables with “combiner plugs” on them at the ends of the cable, where they are joined together.

The generators need to be properly sized so that one does not try to power another unit which leads to overloading and may result in damage to your generator engine or the other one being used.


What is Parallel Circuit?

A parallel circuit has multiple pathways which each appliance can use to receive power from an energy source such as a battery.

This is a safer way to connect generators because if one pathway burns out, the generator will still be able to function on the other pathways until it can be fixed.

Keep this thing in your brain that both paralleling the generator and grounding a generator are different things.

For this type of circuit to work properly, you should place the appliances that need power from each generator into separate circuits from one another, meaning they shouldn’t share anything in common besides the generators themselves.

For example, you shouldn’t install two appliances that need power from one generator into the same circuit because if something went wrong, they would be affected simultaneously instead of just one appliance.


How to Parallel Generators?

With Circuit Connections:

How to parallel generator without circuit connections? Let’s break into it:

  • The first thing you will need to do is purchase a special piece of equipment called a combination generator coupler or generator parallel kit. The installation process of this coupler/kit is relatively easy and requires only a few tools.
  • Now attach 2 generators together using a combination generator coupler. Once this part is done, you can connect appliances that need power from both generators into separate circuits from one another by installing special circuit breakers between each generator and the appliances.
  • Afterward, you should increase the capacity of the circuit breakers on your generators to match that of your appliances by running a single wire from one breaker’s hot terminal to another until all are combined into one large circuit.
  • This provides extra safety for both people and equipment in case there is ever a problem with one of the generators.

With Series Connections:

How to Parallel Generator with series connection?

Parallel wiring for generators is usually implemented with appliances plugged into a single circuit or pathway because it’s more cost-effective and easier to maintain onsite without spending more money on equipment.

However, you can still connect multiple appliances into separate circuits using series wiring, but it’s less safe since one problem in the system can affect all appliances at once.

This is why generator parallel kits are not recommended for this type of connection.

To make a series circuit, you will need to wire two or more appliances to share power from a single outlet or energy source, which works by electrons flowing through each appliance until they reach their destination.

When this happens, the voltage drops across every appliance so that they all receive a usable amount of electricity.

Generators can also be connected to one another in a series circuit by connecting them together along with a special device known as a series generator coupler at both ends in an order that provides equal electrical input and output.

This makes parallel circuits so useful because they can be connected in either order, but series circuits are always connected this way.

Series and Parallel Connect Generators Together:

If you want to connect your generators in a way that combines their power into series and parallel wiring, you should attach new outlets or wires between each generator.

If you’re using extension cords for this, then attach one of the generators to be used as a power source and an outlet on the other end, which will be plugged into either another extension cord or an appliance.

Once this is done, you can connect appliances that need power from both generators into separate circuits by installing special circuit breakers between each generator and the appliances.

For example, you shouldn’t wire two appliances that use power from one generator into the same circuit because if something went wrong, they would be affected simultaneously instead of just one appliance.


Generator Paralleling Problems

Some paralleling problems are mentioned below; we must keep them in mind when paralleling generators.

The first is that you should only connect appliances that require the same amount of power.

If you don’t, one generator will have to work harder than the other, leading to problems.

Another thing you should avoid is connecting two generators to the same circuit breaker.

This can be dangerous because if something goes wrong with one of the generators, then both will be affected.

Finally, you should always make sure that the wiring between the generators is properly done and that there is an adequate amount of load on each generator.
