The 1980s marked Generac’s growth in home backup power solutions which has made the company what it is today. Generac’s home and industry backup power solutions provide up to 2MW of power and are available in formats as diverse as trailer-mounted generators and large home backup generators.

Ever on a growth trajectory, Generac went public in 2010 and continues to develop and innovate in the portable power sector.

Generac’s reputation and profile certainly have enough swagger for them to boast themselves as the “#1 name in home backup generators”. But really, Generac is one of the first brands that come to mind when you look for quality portable power for your home, workshop, or recreational needs. 

In particular, the GP series of portable generators (of which the 8000E is one), are designed specifically as an affordable and reliable power solution that harnesses Generac’s industry-leading innovation.

  • Puncture-proof rugged wheels do not need replacing over the lifetime of the generator and will keep the unit portable over all sorts of surfaces.
  • POWERRUSH™ proprietary advanced technology beefs up the starting capacity of these generators by up to 40%, meaning you get way more productivity from your power.
  • HOMELINK™ compatibility provided by Generac is an amazing manual transfer switch that enables you to let your Generac 8000E generator take over the powering of your home’s hardwired devices like gas furnaces!

The GP8000E has insightful engineering and features that make its use and maintenance hassle-free. Firstly, you will benefit from being able to start the 420cc engine with an electric start, with a 12-volt battery included making sure that this option is always available.

The start switch on the control panel has start, run, and off positions. Alternatively, the classic recoil method is also available if the battery goes flat. The choke for the generator is located on the engine. 

The generous fuel and oil capacity means that you can run this generator for a long time before requiring a refill. The fuel tank has a visual gauge meaning you can stay on top of refills.

Generac recommends 10w30 oil for lubrication which is distributed in the engine by the splash lubrication method. This generator has a low-oil shutdown and the fuel tank shut-off is prominently located on the fuel tank. 

Moving your generator around is easy and the generator comes with never-flat wheels of 9.5 inches in diameter. The wheels need to be assembled on the generator as well as the folding handle that has a comfortable dual grip. 

An easy-to-use control panel that has everything right where you need it.

Aside from robust hardware, the control panel of this generator stands out as being straightforward to use with easy access to a variety of outlets. Here is what you can expect on the control panel:

  • An hour meter so you can keep track of running time.
  • The start switch.
  • Two 120V 20A GFCI (ground fault circuit interrupter) outlets. These outlets can detect ground faults and protect you and your connected equipment by shutting off the power to the outlet.
  • Two 1-pole 20A circuit breakers.
  • One 120V/240V 30A twist-lock outlet
  • A 12V battery charger input
  • One 2-pole 30A circuit breaker.

What can I power with the GP 8000E generator?

With 8000 watts in hand, you have a lot of options for running larger household appliances like furnaces, fridges, freezers, and of course, your lighting.

Many owners of this generator say that it will run a large RV or small house with ease. To prevent overloading, you will need to do a bit of power management homework, jotting down starting and running wattages for your equipment and appliances to ensure that everything can be handled by this generator. 

You can expect to run this generator for up to 15 hours with a 25% load and 10 hours with a 50% load. Keep track of running time via the timer on the control panel. 

Pros and Cons

This is a pretty smart generator but as with any product, there are both pluses and minuses. Let’s take a look at the take-home pros and cons of making this generator your own:

Pros of the Generac GP 8000E Generator

  • Great fuel and oil capacity: it is clear on visual inspection that this generator has prioritized maximizing the fuel tank size and dimension. This makes all the difference to running the unit as you will have less frequent fuel and oil top-ups.
  • High spec engine: the engine makes all the difference in how the generator performs. We also appreciate the splash lubrication that ensures that all parts are kept running smoothly.
  • Compact for its capacity: Generac has nailed a very compact design for the capacity of this generator. It may weigh as much as a man, but it certainly takes up less space.
  • Low oil shut down: is always useful, though you have a whole liter oil tank to work with.
  • Robust overload protection and warning lights: if you overload this generator, you can be confident that it will shut itself off before it does itself damage!

Cons of the Generac GP 8000E Generator

  • More outlets would be great – especially DC: you can never have too many outlets, but the range on this generator is a little sparse, especially as there is no DC outlet.
  • The handle adds a whole lot of excess length: it is almost the same length as the generator making the setup look like a plow.
  • Assembly work is needed: some purchasers were unpleasantly surprised by having to attach the handles, wheels, feet, and wiring up the battery.
  • You have to charge the battery: the generator will not charge the battery itself.

Frequently Asked Questions

Q. Is this generator brushless?

The GP 8000E is a brushless generator. 

Q. Can I use the GP 8000E with propane gas?

To use this generation with propane would require a carburetor conversion. This is entirely possible, but Generac is very clear that this completely invalidates the warranty. Generac does not produce a proprietary liquid propane converter kit for this generator.

Q. Can I connect the Generac GP 8000E directly to a building’s electrical system?
