Zoom on the Firman W02981

In a nutshell, the Firman W02981 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 sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Firman W02981 in use

The Firman W02981

The Firman W02981's engine, 171 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 2,900W and reaches a peak wattage of 3,200W. Additionally, as the generator is parallel capable (Firman parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.

At a noise rating of 58 dBA (less noisy than rainfall), the inverter generator is started via a conventional pull-start mechanism.

Thanks to a fuel capacity of 1.8 gallon, the W02981 can operate for up to 10 hours with a full tank (fuel consumption around 0.18 GPH).

The W02981 generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel provides the upcoming 3 AC outlets:

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

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

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

Portability

Since the Firman W02981 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. This type of design is the most modern and convenient way to recreationally generate power.

The W02981's dry weight of 84 lbs lets you use its power anywhere needed. In addition, with its set of 2 wheels (⌀5") and its folding handle, it may be shifted with ease, once placed on the floor.

Features

Panel of the Firman W02981

The W02981's control panel

The W02981 and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

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

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman W02981 also is packed along with the following accessories: battery charging cables, tool kit, oil and funnel.

Emissions

The Firman W02981 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 W02981 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman W02981 compare to inverter generators of similar power (between 2500 and 3500 W).

  • Since the generator weighs in at a dry weight of 84 lbs, the Firman W02981 belongs in the expected weight range for inverters which can produce between 2500 and 3500 rated watts. If weight is your top priority, one of the champions in this power category is the Pulsar PGD40iSCO, weighing just 46 pounds.
  • 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. 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 for its autonomy, the W02981, with an autonomy of up to 10 hours at a 25% load, is placed on the low end among the generators of its kind. 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.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.18 GPH (gallon per hour) at a 25% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Energizer eZV3500P. With a fuel consumption of as little as 0.13 GPH, it is one of the most efficient generators currently on the market.

Here's a list of the most popular specific comparisons:

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W inverter generators, the Firman W02981 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.

How much oil does my firman w3200i take (Asked July 19, 2020)

Oil capacity is 20.3 oz.

Does this invertor have an inline gas shut off? (Asked October 03, 2021)

The unit has a fuel valve knob. Turning it off will allow you to let the generator run until it stops from lack of fuel, and to dry out all remaining fuel in the carburetor.

What kind of oil mine did not come with oil (Asked January 16, 2022)

For general, all-temperature use, SAE 10W30 is recommended.
