Zoom on the Generac GP3600
In summary, the Generac GP3600 is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
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 GP3600 is powered by a 212 cc Generac OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3600W as well as a peak wattage of 4500W.
Its starting mechanism is based on a conventional pull-start mechanism.
With a full tank, the GP3600 can operate for around 9.3 hours at 50% load (fuel consumption around 0.4 GPH), thanks to its fuel capacity of 3.7 gallons.
The quite high THD (<25%) of the GP3600 makes it unsuitable for powering sensitive electronic devices.
The control panel features the upcoming 5 AC outlets:
Even if this Generac generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.
The design of the Generac GP3600 is a typical, open frame, with the dimensions of L24 x W22.5 x H21.3 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 105 lbs. However, its challenging mobility is solved by a wheel kit (⌀8") and a folding handle, which will ease its displacement, once it is on the floor.
Monitoring of the GP3600's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).
Along the basic documentation and a user manual, useful for starting the generator right away, the Generac GP3600's package also includes these accessories: oil, funnel and tool kit.
The Generac GP3600 is CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor, making it usable in forested areas.
The Generac GP3600 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Generac GP3600 compare to generators of similar power (between 3500 and 4500 W).
- As for its weight, the Generac GP3600 weighs only 105 pounds, making it one of the lighter generators in the 3500-4500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
- As far as autonomy is concerned, providing around 9.3 hours of runtime with a full tank at a 50% load, the GP3600 falls into the low end in comparison with other devices of a comparable power output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000, which is able to run for around 16 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.4 GPH (gallon per hour) at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.
As you can see from this dynamic chart, when compared to other 3500-4500W generators, the Generac GP3600 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
The bottom line
- Several accessories included
- Lightweight for its kind (105 lbs)
- Decent fuel efficiency
- No electric start
- Relatively low run time
