How to Parallel Two Portable Generators

It’s 103 degrees Fahrenheit on a blistering summer afternoon. Your RV is parked in the sun and your family is taking refuge under an awning while you struggle to start your portable generator to run the A/C.  

Generally, it takes more power to start and run an RV air conditioning unit than one portable generator can provide. The problem is, generators large enough to power an air conditioner are not very portable and can’t be moved by one person.

Thankfully, by running two smaller, portable inverter generators in parallel, you can start and run your air conditioner with ease. 

Why Run Generators in Parallel?

Today's demands for mobile power require more than what the traditional portable generator was made for. A basic portable generator will power the necessities for short periods of time, but running multiple generators in parallel will increase the power available to use, and extend the time you can use it. 

Two Small Generators Paralleled TogetherAdditionally, it's much easier to add to your power setup than to purchase a heavier, larger generator on its own. To power the A/C in a mobile home, you're going to want generators that are portable, powerful, and lightweight.

Portable RV inverter generators have all of those benefits and are the best option for paralleling power away from home.

Benefits of Inverter Generators

  • Can be run in parallel for increased power
  • Lightweight and very portable
  • Fuel-efficient (gas and electric)
  • Run very quietly without disturbance
  • Many offer an "eco mode" to vary throttle power during usage
  • Some newer models can run RV A/C units without being paralleled

Tandem Generators

30 Amp OutletIf you already own an inverter generator, you can buy an accompanying compatible unit, which tethers to the original generator with a set of cables, and back to the AC unit. 

The Honda companion unit has a 30-amp twist-lock outlet so you can plug into the air conditioner. In this instance, you'll need to buy the companion generator and the cables separately to complete the kit.

Yamaha Tandem Inverter GeneratorsFor some models, there may be no exclusive companion unit, but you can still parallel most inverter generators with parallel cables that have a 30-amp outlet.

These cables are used to parallel two of the same generators when a companion unit is not available. You can use these cables for 3000-watt inverter generators as well but be sure to only pair matching generators with the same amperage and voltage.


Companion Kits

Companion Generator KitIf you don't have a generator yet or are looking to start fresh, our Honda companion kits and Yamaha parallel kits offer everything you need in one package.

Instead of buying all the components separately, just make one purchase that includes everything you need. Inverter generators that are compatible for pairing together using parallel cables come in one convenient package. All you need to do is pack up and go.


Will 'Paralleling' Damage the Generators?

Generators designed to be paralleled are perfectly safe as long as you follow the manufacturer's instructions, use the proper required cables, and ensure that the generators you are using to parallel are compatible with each other as determined by the manufacturer.
