Paralleling Generators – How Does it Work?

If you already own a 2000 watt inverter generator and need more power to run your RV, paralleling it with another generator would be your best bet. Paralleling generators works great when one unit is not enough to run more demanding equipment such as a large air conditioner. In the following article, we’re going to talk about what paralleling is, why it is often a better choice than getting a single larger generator and what are some of the best paralleling kits available out there.

What is Paralleling Generators?

In a nutshell, paralleling is simply connecting two generators to each other via a dedicated parallel cable or kit. This allows the two generators to join their forces and produce more power.

Eg. if you already own an inverter generator with 2000 starting and 1800 running watts, paralleling it with another similar inverter would give you 4000 starting and 2000 running watts.

Note that not all generators can be paralleled. Only the good quality inverters offer such capability. Honda EU2200i is one of them. A much cheaper yet good alternative is WEN 56200i.

Usually, both inverter generators need to have the same wattage to make paralleling possible. However, in the case of some manufacturers, this is not always a strict requirement. It depends a lot on how the generator engines and parallel kits are built.

Is Running Generators in Parallel a Better Choice than Buying a Large Generator?

In most of the circumstances getting two inverter generators and paralleling them together is a better choice than investing in one individual large generator.

First, in case one of the generators fails you are still left with the other to provide the badly needed power.

Second, you have more flexibility in terms of how you use the generators. If your power needs aren’t high at a specific time then one inverter generator should do the job just fine.

It goes without saying that it’s always a better idea to use two inverters in parallel rather than one open frame generator.
That’s because the inverters produce a clean sine wave, making them suitable for running sensitive portable electronics. This is not the case with the large open frame gens. Small inverters are also much quieter and much easier to carry around than bulky portable generators. This is the big selling point for RV and camping. You will certainly find it much more convenient to walk around with two Honda 2000-watt generators rather than having to push one bulky unit around the campsite.

On the other hand, nowadays you can find the medium-sized 3000-watt inverter generators that are ideal for RVs. They should run all your RV equipment (including a 13,500 BTU AC) without having to parallel them with another generator.

One such inverter generator is Champion 3400 Dual Fuel Inverter. It is a good dual fuel inverter and an extremely popular choice for RV.

The even better news is that you can also parallel this unit with another Champion 3000 watt inverter generator too.

So if for example, your friend gets this generator for their RV, you can connect them together and have a great uninterrupted power supply to run pretty much everything in both of your travel trailers.

Can you parallel two different brand generators?

Usually yes, but both generators should ideally have the same wattage.

What’s more, the frequency and voltage of connection should be the same too.

For example, a lot of users reported paralleling Honda EU2000i with WEN56200i successfully.

The same goes for WEN56200i paralleled with Yamaha EF2000iSv2.

If in doubt, I’d suggest asking this question at your generator’s listing page on Amazon.

You’ll probably find other users who will be happy to share their experiences with paralleling this specific generator with another brand.
