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)

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 not included), this power can be doubled when linked to another similar or compatible unit.

Enjoying a noise rating of 58 dBA (less noisy than a quiet suburb), this inverter generator can be started thanks to a simple traditional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).

The WH02942, with a fuel capacity of 1.8 gallon, reaches a run time of up to 9 hours utilizing gasoline (fuel consumption around 0.2 GPH). Unfortunately, and despite our research efforts, we couldn't find any information regarding its runtime when using propane. Don't hesitate to let us know if you know it.

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

The generator will allow you to simultaneously power various devices, for example:Note: The examples above are based on a maximum load of 75% and estimated wattages. The devices also may not be able to start at the same time. For a more accurate estimation, use our wattage calculator.

Outlets

The control panel features the following 3 AC outlets:

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

Additionally, it features 2 DC outlets: there's a 5V USB port with which you may charge electronics, for example mobile phones or tablets, conveniently and a 12V 8A receptacle with which you may charge your batteries with ease.

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 esthetical than conventional, open frame products. This type of design is the most modern and convenient way to recreationally generate power.

The 97 lbs of the WH02942's dry weight enables you to use it anywhere you will ever need. In addition, with a wheel kit (⌀5") and a folding handle, it may be displaced with ease, once placed the floor.

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 overloaded.

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.

Along the basic documentation and a user manual, useful for starting the generator right away, the Firman WH02942's package also includes these accessories: oil, funnel, tool kit, propane hose and battery charger.

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, so it is adequate 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).

  • 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 Honda EG2800i, standing at just 66.6 lbs.
  • Since this inverter generator is rated for a lowest possible noise of 58 dBA, it can be considered as one of the more quiet of the products generating similar power. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
  • As for its autonomy, the WH02942, with an autonomy of 9 hours at a 25% load, is placed on the low end among the generators of its kind. 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 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. Compared to its peers, this inverter generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.2 GPH at a 25% load. If fuel consumption is your top priority, we suggest to check out the Energizer eZV3200P, 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 dynamic 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.
