An affordable solution for recreational applications. Perfect size for tailgating,camping and power tool use. (source: Generac (opens in a new tab))

Zoom on the Generac GP3000i

In a nutshell, the Generac GP3000i is a compact and lightweight portable inverter generator mostly geared towards:

  • Camping and tailgating hobbyists looking for a portable power source
  • DIYers who wish to improve their efficiency with tools
  • RV travellers looking for even more independence

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Generac GP3000i in use

The Generac GP3000i

The Generac GP3000i's engine, 149 cc Generac OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 2300W and reaches a peak wattage of 3000W. In addition, the device is parallel capable (Generac 7668 Parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.

This inverter generator is started via a simple traditional pull-start mechanism. It features Generac's PowerDial™, an easy-to-use dial with three operation settings.

Thanks to a fuel capacity of 1.06 gallon, the GP3000i can operate for up to 5.8 hours with a full tank (fuel consumption around 0.18 GPH).

Delicate electronics can be plugged in an AC outlets safely, as the GP3000i generates a clean sine wave, reaching a <3% Total Harmonic Disruption (THD).

Outlets

The control panel provides the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

It also sports 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

This Generac generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.

Portability

Thanks to its closed inverter generator design (L22.2 x W13.3 x H18.4 in), the Generac GP3000i, is more esthetical than a typical, open frame generator. This type of design is the most modern and convenient way to recreationally generate power.

The GP3000i's dry weight of 59.5 lbs lets you use its power anywhere needed. Additionally, a conveniently placed handle (molded in the case) is a great enhancement to the grip, which tremendously helps when moving the GP3000i across any distance.

Features

Panel of the Generac GP3000i

The GP3000i's control panel

Some light indicators allow you to instantly see if the oil level is too low, the generator is on overload and the generator is ready.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Along with the aforementioned features, from an accessory standpoint, the Generac GP3000i's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

Emissions

The Generac GP3000i is CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

The Generac GP3000i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac GP3000i compare to generators of similar power (between 1500 and 2500 W).

  • At a weight of 59.5 pounds, the Generac GP3000i places in the expected weight range of the generators in the 1500-2500 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Genmax GM2000i, with a dry weight of only 34.2 lbs.
  • As for its autonomy, the GP3000i, with an autonomy of up to 5.8 hours at a 25% load, is placed on the low end among the generators of its kind. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse WH2200iXLT, which is able to run for up to 13 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This inverter generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.18 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV2200P, with a fuel consumption of 0.08 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 1500-2500W generators, the Generac GP3000i is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
