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))

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.

With a noise rating of 58 dBA (less noisy than a refrigerator), the inverter generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).

With a fuel capacity of 1.8 gallon, the WH02942 can operate for up to 10 hours using gasoline (fuel consumption around 0.18 GPH), or for up to 19 hours (estimation based on a 20 lbs tank - propane consumption around 0.25 GPH) using propane.

The WH02942 produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel includes 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 with which charging of electronics like mobile phones and tablets is made convenient and a 12V 8A receptacle with which you may charge your batteries with ease.

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. The design follows the contemporary trends and is perfect for recreationally generating power.

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

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

In addition to this info, the light indicators show you if its oil levels are insufficient, the generator is ready and the generator is on overload.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

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, tool kit, propane hose, oil and funnel.

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, 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 inverter generators of similar power (between 2500 and 3500 W).

  • Having a dry weight of 90 lbs, the Firman WH02942 belongs in the expected weight range for inverter generators which produce 2500 to 3500 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGD40iSCO, with a dry weight of just 46 pounds.
  • With a lowest possible noise of 58 dBA, this inverter generator places itself amongst the more quiet of the products delivering 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.
  • Autonomy-wise, with up to 10 hours on a full tank at a 25% load, the WH02942 is on the low end when compared to other inverter generators of a similar power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200914, reaching up to 22 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 0.18 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 are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you could look out for.

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.

    Does the noise/sound level vary much when using propane instead of gasoline? We use propane. I’m reworking my sound box, and considering how much effort to put into improving the sound box.

    We purchased online through Costco and had it delivered last year. I thought I would need two units joined together so I ordered two. One had a broken case. Turned out only one was sufficient for our GD 23BHE trailer. Costco and Firman were great about picking up the broken unit. Of course a broken unit should never have been delivered in the first place.

    Thanks for your review.

    + PROS:
    • Propane option ready to go, and is clean enough for us to put the generator under the dining table in the RV/trailer while traveling.
    - CONS:
    • Generally solid

    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.

    + PROS:
    • Price. Costco Canada has them for 800 CND ,which is about 575 USD.
    • Oh, and LIFETIME parts warranty!
    • Overall quality is great.
    • You can't beat that Value !!
    - CONS:
    • Could be more economical and quieter
