Description
Zoom on the Firman H05751
In a nutshell, the Firman H05751 is a portable generator mostly geared towards:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- Food truck owners who do not wish to see their business interrupted under any circumstances
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to ensure that a power failure will not prevent them from working
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The Firman H05751
With its dual-fuel technology, the powerful and versatile Firman H05751 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 5700W along with a peak wattage of 7125W. While propane-powered, it provides 5700 rated watts and 7125 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 simple and elegant electric starter (battery included).
The running time of the H05751, with its 8 gallons fuel capacity, can reach around 13 hours at 50% load on a full tank of gasoline (fuel consumption around 0.62 GPH). With propane, it can reach around 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH).
The H05751 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).
Outlets
The control panel features the following 6 AC outlets:
While this Firman generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, because the H05751 is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
Portability
The dimensions of the Firman H05751, 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. The design is ideal for rough environments and demanding outdoor use.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 196 lbs. Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
Features
The H05751's control panel
To help you monitor the H05751's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
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.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman H05751 also is packed along with the following accessories: funnel, tool kit, propane hose and oil.
Emissions
The Firman H05751 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.
Product Videos
The Firman H05751 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman H05751 compare to generators of similar power (between 5500 and 6500 W).
- At a weight of 196 pounds, the Firman H05751 places in the expected weight range of the generators in the 5500-6500 rated wattage range. If weight is your top priority, one of the champions in this power category is the Lifan LF7250, weighing just 140 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 noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU7000iS with only 52 dBA.
- Since the H05751 boasts with a run time of around 13 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Cat RP5500, as it provides around 15 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 0.62 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Lifan ESI 7000iER-EFI, with a fuel consumption of 0.38 GPH could be in your good books.
Price comparison
As you can see from this interactive chart, when compared to other 5500-6500W generators, the Firman H05751 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.
