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:

  • DIYers who wish to improve their efficiency with tools
  • Homeowners in need of an emergency backup power for their essentials
  • Camping and tailgating hobbyists looking for a portable power source
  • RV travellers who wish to upgrade their experience to another level

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 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, as it is parallel capable (Firman parallel kit (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.

With a noise rating of 58 dBA (less noisy than a quiet suburb), the inverter generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included).

The WH02942, with a fuel capacity of 1.8 gallon, reaches a run time of up to 10 hours utilizing gasoline (fuel consumption around 0.18 GPH). Alternatively, it can reach a run time of up to 19 hours (estimation based on a 20 lbs tank - propane consumption around 0.25 GPH) with propane.

The WH02942 generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the upcoming 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 with which charging your batteries is made easy.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready.

Portability

As the Firman WH02942 is an inverter generator, its encased design (L23.2 x W17.8 x H17.9 in) offers more aesthetics than a conventional, open frame product. This modern design aims to provide an ideal power solution to recreational users.

As the WH02942's weight is only 90 lbs, it can follow you and your power needs anywhere. Furthermore, once placed on the floor, effortless displacement is possible thanks to its set of 2 wheels (⌀5.5") and its folding handle.

Features

Panel of the Firman WH02942

The WH02942's control panel

The control panel of the WH02942 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, the device’s light indicators will display if the generator is on overload, the generator is ready and the oil level is too low.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman WH02942 also is packed along with the following accessories: battery charger, funnel, propane hose, tool kit and oil.

Emissions

The Firman WH02942 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use 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).

  • Regarding its weight, the Firman WH02942 only weighs in at 90 pounds, which means it's one of the lighter generators in the 2500-3500 rated wattage range. In terms of weight, one of the champions in their power range is the Generac GP3300i, standing at just 59.5 lbs.
  • At a lowest noise rating of 58 dBA, this inverter generator is one of the quieter devices of similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
  • The WH02942's autonomy is somewhat low end compared to devices of its power range, as it reaches only up to 10 hours at 25% load on a full tank. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 200954, which is able to run for up to 22 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. As this inverter generator uses an estimated 0.18 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. 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.

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.
