Generac 7668 parallel kit with reset buttons and ground terminal for pairing two inverter generators

The Generac Inverter Parallel Kit for GP3000i, GP3300i and iQ3500 Connects Two Matching Inverters for Twice the Power

The Generac Inverter Parallel Kit, model 7668-0, is a cable box that connects two matching Generac inverter generators. It is rated 120V 50A and has a 14-50R receptacle and a TT-30R receptacle for RV plugs.

Generac names the GP3000i, GP3300i and iQ3500 for this kit. Use two of the same model. It is not for the GP2200i or GP2500i, which use kit 7118.


Generac Inverter Parallel Kit for GP3000i, GP3300i and iQ3500 Features

14-50R and TT-30R Outlets

The front panel has a 120V 50A 14-50R receptacle and a 120V 30A TT-30R receptacle for RV plugs. Reset buttons for each outlet sit between the receptacles.

Made for Two of the Same Model

Generac's literature shows two GP3000i, two GP3300i or two iQ3500 units. Pair like with like.

Carry Handle and Compact Box

The box measures 9.84 x 4.33 x 8.27 inches and weighs 3.53 lb. A carry handle makes it easy to bring along.

Ground Terminal on the Panel

A ground terminal on the panel is marked GND, so you can bond the kit as the instructions direct.


Real-World Applications

RV Camping. Run a 50A or 30A RV cord from the box and use the power of two inverters together.

Backup Power. Combine two matching inverters when one cannot carry all the loads you need.

Tailgating and Events. Pair two units to run more equipment from one outlet panel.


Practical Comparison

Versus Running Two Units Separately. Without a kit, each inverter powers only its own outlets. The kit combines them into one pair of outlets.

Versus the 7118 Kit. Kit 7118 serves the GP2200i, GP2500i, GB1000 and GB2000. This 7668-0 kit serves the GP3000i, GP3300i and iQ3500.


Is the 7668 Parallel Kit the Right Fit

  • Fits. GP3000i, GP3300i and iQ3500 (models 7127 and 7723 CoSense), two of the same model.
  • Output. Rated 120 VAC, 50 A. Generac does not give a combined wattage for the pair.
  • Warranty. 90 day limited, residential and commercial.

This May Be a Good Fit If

  • You own two GP3000i, two GP3300i or two iQ3500 inverters.
  • You need a 14-50R or TT-30R outlet.
  • You want to double up the units you already have.
