Zoom on the Firman H08051

In a nutshell, the Firman H08051 is a portable generator mostly geared towards:

  • Food van owners and people participating in sporting competitions, open-air performances and outdoor festivals
  • Professionals who want to ensure that a power failure will not prevent them from working

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 H08051 in use

The Firman H08051

Thanks to its dual-fuel technology, the Firman H08051 delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 8000W and a peak wattage of 10000W. When propane-powered, it has 7250 rated watts and 9050 peak watts.

Enjoying a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included).

As for its running time, the H08051, along with its 8 gallons fuel capacity, can run for around 12 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.67 GPH). If propane is used, it can operate for around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH).

The H08051 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).

The generator will allow you to simultaneously power various devices, for example:Note: Not all of these items may be able to start at the same time. These examples are based on a maximum load of 75 % and on wattage estimates. Use our wattage calculator to find out if this product will be suitable for your needs.

Outlets

The control panel features the upcoming 5 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

This Firman generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, due to the featured twist-lock L14-30R receptacle, the H08051 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

With its dimensions of L29.8 x W27.5 x H26.1 in, the conventional, open frame design of the Firman H08051 offers stability and allows the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 212 pounds. However, its challenging mobility is solved by a wheel kit (⌀10") and a folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Firman H08051

The H08051's control panel

The control panel of the H08051 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

With the basic documentation and a user manual, letting you start the generator quickly, the Firman H08051 also comes with several accessories, including: funnel, tool kit, oil and propane hose.

Emissions

The Firman H08051 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, which makes it suitable for use in forested areas.

The Firman H08051 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H08051 compare to generators of similar power (between 7500 and 8500 W).

  • With a dry weight of 212 pounds, the Firman H08051 finds itself in the expected weight range for generators able to produce between 7500 and 8500 rated watts. If weight is your top priority, one of the champions in this power category is the Lifan LF8750iEPL, weighing just 185 pounds.
  • Since the generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Powermate DF7500E, whose lowest noise levels reach just 68 dBA.
  • With a run time of 12 hours at 50% load, the H08051 has one of the higher run times, compared to its similarly powerful peers.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator This generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.67 GPH (gallon per hour) at 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse WPro8500. With a fuel consumption of as little as 0.55 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this dynamic chart, when compared to other 7500-8500W generators, the Firman H08051 is on the average side of the price range.

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