Zoom on the Firman W02981

In summary, the Firman W02981 is a quiet and compact portable inverter generator especially useful for:

  • Amateur DIY lovers
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating buffs looking to enhance their experience
  • RV travellers who wish to upgrade their experience to another level

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from and any relevant emission compliance details.

Power & Run Time

The Firman W02981 houses a 171 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 2900W along with a peak wattage of 3200W. 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.

At a noise rating of 59 dBA (less noisy than a conversation at home), the inverter generator offers the possibility to start the device via a simple traditional pull-start mechanism.

The fuel capacity of 1.8 gallon allows the W02981 to operate for up to 9 hours with a full tank (fuel consumption around 0.2 GPH).

Delicate electronics can be plugged in an AC outlets safely, as the W02981 generates a clean sine wave, reaching a <3% Total Harmonic Disruption (THD).

Outlets

The control panel provides the upcoming 3 AC outlets:

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

Furthermore, it has 2 DC outlets: there's a 12V 8A receptacle allowing you to easily charge your batteries and a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient.

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

Portability

As the Firman W02981 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.

With a dry weight of 82 lbs, the W02981 can easily follow you wherever your power needs are. Moreover, a wheel kit (⌀5") and a folding handle allows you to effortlessly displace it once it's on the ground.

Features

Panel of the Firman W02981

The W02981's control panel

The control panel of the W02981 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, when the generator is on overload, the generator is ready and its oil levels are insufficient, you will be informed by the featured light indicators.

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 a user manual, useful for starting the generator right away, the Firman W02981's package also includes these accessories: oil, battery charging cables, tool kit and funnel.

Emissions

The Firman W02981 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, 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 generators of similar power (between 2500 and 3500 W).

  • In terms of its dry weigh, the Firman W02981 stands at only 82 lbs, meaning that is one of the one of the lighter devices of the 2500-3500 rated wattage category If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • With a lowest possible noise of 59 dBA, this inverter generator places itself amongst the more quiet of the products delivering similar power. If noise emissions are one of your priorities, you may be interested in the Honda EU3000iS, one of the least noisy generators similarly powerful as this one, rated for 50 dBA.
  • Regarding its autonomy, the autonomy of the W02981, reaching up to 9 hours at a 25% load, can be considered as low end, compared to other products of a roughly equal output. 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 up to 20 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. Standing at an estimated 0.2 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 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 W02981 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
