Zoom on the Firman WH02942
In summary, the Firman WH02942 is a quiet and compact portable inverter generator especially useful for:
- Handcrafting enthusiasts who wish to work on-the-go
- Homeowners in need of an emergency backup power for their essentials
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
- RV travellers wishing to enhance their freedom and nomad lifestyle
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 dual-fuel technology of the Firman WH02942 allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 2900W and a starting wattage of 3200W. If propane-powered, it gives 2600 rated watts and 2900 starting watts. In addition, the device is parallel capable (Firman parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.
The inverter generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 58 dBA (less noisy than a conversation at home).
Regarding its running time, the WH02942, with a 1.8 gallon fuel capacity can operate for up to 9 hours with a full tank of gasoline (fuel consumption around 0.2 GPH). When using propane, it can run for up to 17 hours (estimation based on a 20 lbs tank - propane consumption around 0.28 GPH).
As the WH02942 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.
The control panel features the upcoming 3 AC outlets:
Furthermore, it has 2 DC outlets: there's a 5V USB port allowing you to conveniently charge electronics such as mobile phones and tablets and a 12V 8A receptacle with which charging your batteries is made easy.
This Firman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').
Thanks to its closed inverter generator design (L23.2 x W17.8 x H17.9 in), the Firman WH02942, is more esthetical than a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.
As the WH02942's weight is only 97 lbs, it can follow you and your power needs anywhere. Moreover, its wheel kit (⌀5") and its folding handle will allow you to effortlessly shift it once it's on the ground.
The WH02942's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.
In addition to this info, several light indicators serve to show you when the generator is ready, the oil level is too low and the generator is overloaded.
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 an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman WH02942's package also includes these accessories: battery charger, funnel, propane hose, tool kit and oil.
The Firman WH02942 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor and thus, may be used in forested areas.
The Firman WH02942 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman WH02942 compare to generators of similar power (between 2500 and 3500 W).
- At a weight of 97 pounds, the Firman WH02942 places in the expected weight range of the generators in the 2500-3500 rated wattage range. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
- As its lowest possible noise is rated at 58 dBA, this inverter generator qualifies as one of the more quiet of the products of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
- Autonomy-wise, with up to 9 hours on a full tank at a 25% load, the WH02942 is on the low end when compared to other generators of a similar power output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EU3000iS, which is able to run for up to 20 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 reaches an estimated fuel consumption of 0.2 GPH (gallon per hour) at a 25% load, making it average, for the previously mentioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV3200P, with a fuel consumption of 0.13 GPH could be in your good books.
As you can see from this interactive chart, when compared to other 2500-3500W generators, the Firman WH02942 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
