Description

The FIRMAN WH02942 Inverter generator features 3200 starting watts and 2900 running watts. Power is supplied by our Max Pro Series 171cc FIRMAN engine which runs cool and efficient thanks to its Phoenix Fat Head Block. Our Whisper Series muffler keeps the Wh02942 running a quiet 58 decibels – well below the standards set by the National Parks Service, and our spark arrester has been approved by the USDA Forest Service. The 1.8-gallon fuel capacity provides a whopping 9 hours of run time. Starting is simple with the reliable FIRMAN electric start system. (source: Firman (opens in a new tab))

Zoom on the Firman WH02942

In a nutshell, the Firman WH02942 is a quiet and compact portable inverter generator mostly geared towards:

  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating buffs looking to enhance their experience
  • RV travellers who wish to upgrade their experience to another level

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Firman WH02942 in use

The Firman WH02942

With its dual-fuel technology, the powerful and versatile Firman WH02942 provides an output of 120V. While gasoline-powered, it gives a running wattage of 2900W along with a peak wattage of 3200W. While propane-powered, it provides 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.

At a noise rating of 58 dBA (less noisy than a quiet suburb), this inverter generator can be started via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included).

The running time of the WH02942, with its 1.8 gallon fuel capacity, can reach up to 9 hours on a full tank of gasoline (fuel consumption around 0.2 GPH). With propane, it can reach up to 17 hours (estimation based on a 20 lbs tank - propane consumption around 0.28 GPH).

Delicate electronics can be plugged in an AC outlets safely, as the WH02942 generates a clean sine wave, reaching a <3% Total Harmonic Disruption (THD).

Outlets

The control panel features the following 3 AC outlets:

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

It also sports 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 allowing you to easily charge your batteries.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready.

Portability

Since the Firman WH02942 is an inverter generator, its closed design (L23.2 x W17.8 x H17.9 in) has an esthetical advantage over conventional, open frame devices. The design follows the contemporary trends and is perfect for recreationally generating power.

The WH02942's dry weight of 97 lbs lets you use its power anywhere needed. Furthermore, once placed on the floor, effortless displacement is possible thanks to its wheel kit (⌀5") and its folding handle.

Features

Panel of the Firman WH02942

The WH02942's control panel

The WH02942 and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, some light indicators allow you to instantly see if the oil level is too low, the generator is overloaded and the generator is ready.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman WH02942, the following accessories are also included: tool kit, funnel, propane hose, battery charger and oil.

Emissions

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 therefore, can 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).

  • With a dry weight of 97 pounds, the Firman WH02942 finds itself in the expected weight range for generators able to produce between 2500 and 3500 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • At a lowest noise rating of 58 dBA, this inverter generator is one of the quieter devices of similar power. If you are concerned with noise, check out the Honda EU3000iS, which is one of the least noisy generators in its power range, with a noise rating of just 50 dBA.
  • As far as autonomy is concerned, providing up to 9 hours of runtime with a full tank at a 25% load, the WH02942 falls into the low end in comparison with other devices of a comparable power output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EU3000iS, with up to 20 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. Standing at an estimated 0.2 GPH (gallon per hour) at a 25% load, this inverter generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Energizer eZV3200P, which boasts with a gas consumption of only 0.13 GPH, may be the right generator for you.

Price comparison

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.

Unlike many websites, we did our best to research each of the specs above. That being said, we are not immune to making the occasional mistake or omission. Should you notice any missing or incorrect values, don't hesitate to suggest improvements so we can address the issue.
* Propane runtime is our own estimation, based on a 20 lbs tank and NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs of propane = 1 gal of gasoline.
