Description

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 buffs looking to enhance their experience
  • Handcrafting enthusiasts who wish to work on-the-go
  • RV travellers wishing to enhance their freedom and nomad lifestyle

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Generac GP3000i in use

The Generac GP3000i

The Generac GP3000i is powered by a 149 cc Generac OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 2300W as well as a peak wattage of 3000W. Moreover, since it is parallel capable (iQ3500 Parallel kit 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.

The fuel capacity of 1.06 gallon allows the GP3000i to 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 includes the following 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 you may charge electronics, for example mobile phones or tablets, conveniently.

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

Since the Generac GP3000i is an inverter generator, its closed design (L22.2 x W13.3 x H18.4 in) has an esthetical advantage over conventional, open frame devices. The featured design follows the latest trends and is ideal for easy and recreational use.

As the GP3000i's weight is only 59.5 lbs, it can follow you and your power needs anywhere. 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

The light indicators show you if the oil level is too low, the generator is ready and the generator is overloaded.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

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. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

Product Video

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. Regarding dry weight, one of the champions in the same power range is the Champion 200949, with a dry weight of only 38.6 lbs.
  • As far as autonomy is concerned, providing up to 5.8 hours of runtime with a full tank at a 25% load, the GP3000i falls into the low end in comparison with other devices of a comparable power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Westinghouse WGen2000, boasting with up to 26 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.18 GPH. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.08 GPH, the Predator 2000 is a device you should look out for.

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.
