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))

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

Thanks to its dual-fuel technology, the Firman WH02942 delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 2,900W and a peak wattage of 3,200W. When propane-powered, it has 2,600 rated watts and 2,900 peak 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 is rated for a noise of 58 dBA (less noisy than a conversation at home). Its starting mechanisms include a conventional pull-start mechanism and 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.

Sensitive electronics can be safely plugged in the AC outlets, as the WH02942 produces a clean sine wave, with a <3% Total Harmonic Distortion (THD).

Outlets

The control panel features the upcoming 3 AC outlets:

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

In addition, it provides 2 DC outlets: there's a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient 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').

Portability

The Firman WH02942 is an inverter generator and has an encased design of the following dimensions: L23.2 x W17.8 x H17.9 in. Thus, it is more aesthetical than conventional, open frame products. The featured design follows the latest trends and is ideal for easy and recreational use.

The WH02942 can be taken anywhere with you, thanks to its weight of 90 lbs. Moreover, its set of 2 wheels (⌀5.5") and its folding handle will allow you to effortlessly shift it once it's on the ground.

Features

Panel of the Firman WH02942

The WH02942's control panel

To help you monitor the WH02942's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.

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

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

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: propane hose, oil, tool kit, funnel and battery charger.

Emissions

The Firman WH02942 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all 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 inverter generators of similar power (between 2500 and 3500 W).

  • At a weight of 90 pounds, the Firman WH02942 places in the expected weight range of the inverter generators in the 2500-3500 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Pulsar PGD40iSCO, with a dry weight of only 46 lbs.
  • With a lowest possible noise of 58 dBA, this inverter generator places itself amongst the more quiet of the products delivering 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.
  • The WH02942's autonomy is somewhat low end compared to devices of its type and power range, as it reaches only up to 10 hours at 25% load on a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 200914, boasting with 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 fuel consumption is your top priority, we suggest to check out the Energizer eZV3500P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W dual fuel inverter generators, the Firman WH02942 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.

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.

    Great generator.Priced like a 2000w machine, but out put double to those smaller machines.

    Firman stands behind their products.
    I asked and was told that the LT warranty included, the Generator Brushes, Electric Starter motor, and Propane regulator.

    • Oh, and LIFETIME parts warranty!
    • Overall quality is great.
    • You can't beat that Value !!
    - CONS:
