Description

Zoom on the Generac iQ3600DF

In a nutshell, the Generac iQ3600DF is a portable inverter generator mostly geared towards:

  • Amateur DIY lovers
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating hobbyists looking for a portable power source
  • Professionals who want to be able to deliver results, even during a power failure
  • 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.

Power & Run Time

Featuring dual-fuel technology, the Generac iQ3600DF provides 120V, and offers both power and versatility. Running on gasoline, it delivers a running wattage of 2,800W and a starting wattage of 3,600W. When propane-powered, it offers 2,500 running watts and 3,200 starting watts. Moreover, the parallel capability (parallel kit (opens in a new tab) not included) enables doubling of power output when paired with another similar or compatible unit, providing increased energy capacity and versatility for a wide range of needs.

This inverter generator features a standard recoil pull-rope starting mechanism, but also a practical and straightforward electric starter (battery included).

Regarding its running time, the iQ3600DF, with a 3.17 gallons fuel tank, can operate for around 13 hours at 50% load with a full gasoline tank (with fuel consumption estimated at around 0.24 gallons per hour). It also offers around 16 hours (on a 20 lbs tank - propane consumption around 0.29 GPH) of operation when using propane.

The iQ3600DF generates a clean sine wave with <3% Total Harmonic Distortion (THD), ensuring minimal electrical noise and fluctuations. This feature makes it ideal for powering sensitive electronics, providing stable and reliable AC power through the outlets.

Outlets

The control panel includes the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) with which you may charge electronics, for example mobile phones or tablets, conveniently.

While this Generac generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.

Portability

Thanks to its closed inverter generator design (L24.6 x W20.3 x H22.5 in), the Generac iQ3600DF not only offers superior aesthetics but also operates with reduced noise levels compared to a typical, open frame generator. This modern design aims to provide an ideal power solution to recreational users.

Despite its weight of 107 lbs, the generator is still considered 'portable,' meaning it is movable, although its heftiness may restrict portability in certain environments or require additional considerations for transportation and setup. However, the constrained maneuverability is addressed with the assistance of its set of 2 wheels and its folding handle, allowing for easy shifting once the generator is placed on the ground.

Features

Enhancing monitoring capabilities, the iQ3600DF features a digital data center within its control panel, furnishing essential details on the power output, lifetime run hours and fuel level for tracking activity and status.

In addition to this info, light indicators on the device will signal if the generator is on overload and its oil levels are insufficient.

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

The iQ3600DF also benefits from Generac’s COsense® carbon monoxide monitoring. This technology senses and manages CO output and shuts down the unit when necessary, to protect you from CO poisoning.

Apart from the standard documentation and an owner's manual (opens in a new tab) to facilitate setup, the Generac iQ3600DF features extra accessories: funnel, propane hose, oil and tool kit.

The Generac iQ3600DF versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac iQ3600DF compare to inverter generators of similar power (between 2500 and 3500 W).

  • With its weight of 107 lbs, the Generac iQ3600DF is one of the heavier inverter generators in the 2500-3500 rated wattage category. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGD40iSCO, with a dry weight of just 46 pounds.
  • Among its inverters with similar power, the iQ3600DF offers one of the highest run times, running for around 13 hours at 50% load.
  • 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. With a fuel consumption rate around 0.24 GPH (gallon per hour) at 50% load, this inverter generator is one of the more fuel-efficient models within the aforementioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PGD40iSCO. With a fuel consumption of as little as 0.22 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from these interactive charts, when compared to other 2500-3500W dual fuel inverter generators, the Generac iQ3600DF is on the average side of the price range.

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