Zoom on the Generac GP3000i

In summary, the Generac GP3000i is a compact and lightweight portable inverter generator especially useful for:

  • Camping and tailgating buffs looking to enhance their experience
  • DIYers who wish to improve their efficiency with tools
  • RV travellers who wish to upgrade their experience to another level

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 houses a 149 cc Generac OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 2300W along with a peak wattage of 3000W. Moreover, since it is parallel capable (Generac 7668 Parallel kit (opens in a new tab) not included), its power may be doubled if linked to a second compatible unit.

This inverter generator is started via a conventional 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).

The GP3000i produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the upcoming 3 AC outlets:

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

Additionally, it features 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.

This Generac generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.

Portability

The Generac GP3000i is an inverter generator and has an encased design of the following dimensions: L22.2 x W13.3 x H18.4 in. Thus, it is more aesthetical than conventional, open frame products. The featured design follows the latest trends and is ideal for easy and recreational use.

The GP3000i can be taken anywhere with you, thanks to its weight of 59.5 lbs. Furthermore, moving the GP3000i from A to B is made easier thanks to its convenient handle (molded in the case), which vastly improves your grip.

Features

Panel of the Generac GP3000i

The GP3000i's control panel

When the generator is on overload, the oil level is too low and the generator is ready, you will be informed by the featured light indicators.

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.

Accessory-wise, along with the previously mentioned features, the Generac GP3000i is packaged with the standard documentation and an owner's manual (opens in a new tab), helping you start the device right away.

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, which makes it suitable for use 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).

  • Since the generator weighs in at a dry weight of 59.5 lbs, the Generac GP3000i belongs in the expected weight range for devices which can produce between 1500 and 2500 rated watts. If weight matters to you, one of the champions in this power range is the Champion 200949 with only 38.6 pounds.
  • 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 WGen2000, which is able to run for up to 26 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.18 GPH at a 25% load. If fuel consumption is your top priority, we suggest to check out the Predator 2000, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.

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.
