Zoom on the Firman H08051
In a nutshell, the Firman H08051 is a portable generator mostly geared towards:
- Food truck owners who do not wish to see their business interrupted under any circumstances
- Professionals in need of safely powering high-intensity work or lighting equipment
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
With its dual-fuel technology, the powerful and versatile Firman H08051 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 8000W along with a peak wattage of 10000W. While propane-powered, it provides 7250 rated watts and 9050 starting watts.
With a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), the generator features a conventional pull-start mechanism, but also a convenient and easy-to-use 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).
Since the H08051 has a somewhat high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.
The control panel features the upcoming 5 AC outlets:
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, as it features a twist-lock L14-30R receptacle, the H08051 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.
The dimensions of the Firman H08051, which are L29.8 x W27.5 x H26.1 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 212 lbs make it incredibly difficult to manually lift and transport. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.
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 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.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman H08051 also is packed along with the following accessories: oil, funnel, propane hose and tool kit.
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).
- At a weight of 212 pounds, the Firman H08051 places in the expected weight range of the generators in the 7500-8500 rated wattage range. 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. For those who are looking for a less noisy device, we suggest the Powermate DF7500E. With just 68 dBA, it is one of the most quiet devices in this power range.
- With a run time of around 12 hours at 50% load, the H08051 has one of the highest 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 can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.67 GPH (gallon per hour) at 50% load, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.55 GPH, the Pulsar PG10000B16 is a device you should look out for.
As you can see from this interactive 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.
