Zoom on the Firman H05751

In a nutshell, the Firman H05751 is a portable generator mostly geared towards:

• RV travellers looking for even more independence
• People occasionally participating in sporting competitions, open-air performances and outdoor festivals
• Food truck owners who do not wish to see their business interrupted under any circumstances
• Homeowners in need of an emergency backup power for their essentials
• 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, and the extra features it benefits from.

Power & Run Time

The Firman H05751

Delivering 120/240V, the Firman H05751 is enhanced by dual-fuel technology, providing power and versatility. Running on gasoline, it boasts a running wattage of 5,700W and a starting wattage of 7,125W. Alternatively, when propane-powered, it delivers 5,700 running watts and 7,125 starting 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 user-friendly and efficient electric starter (battery included).

Regarding its running time, the H05751, with a 8 gallons fuel tank, can operate for around 12 hours at 50% load with a full gasoline tank (with fuel consumption estimated at around 0.67 gallons per hour). It also offers around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH) of operation when using propane.

As the H05751 has a high THD (<25%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI

120V 30A (L5-30R) receptacle

120/240V 30A (L14-30R) receptacle

While not classified as 'RV Ready,' this Firman generator can still provides the advantage of RV connection via its L5-30R receptacle, ensuring power supply to your RV with an L5-30P to TT-30R adaptor. Besides, thanks to its twist-lock L14-30R receptacle, the H05751 is transfer switch ready, facilitating easy hookup to your breaker box to provide backup power for your home during blackouts.

Portability

Measuring L30.2 x W27.5 x H26.3 in, the classic open frame build of the Firman H05751 delivers stability and easy maintenance access to components, facilitating air circulation. This type of design is ideal for tough environments and heavy outdoor use.

While technically classified as 'portable' due to its ability to be moved, the 194.5 lbs of this generator may make manual lifting and transportation somewhat difficult. However, the constrained maneuverability is addressed with the assistance of its wheel kit (⌀10") and its folding handle, allowing for easy shifting once the generator is placed on the ground.

Features

The H05751's control panel

The H05751's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, providing voltage, frequency, and lifetime hours data.

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).

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman H05751, the following accessories are also included: oil, propane hose, tool kit and funnel.

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 dual fuel generators of similar power (between 5500 and 6500 W).

• As its dry weight is 194.5 pounds, the Firman H05751 is one of the heavier of the dual fuel products which can generate 5500 to 6500 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGDA70BiSCO, with a dry weight of just 118 pounds.
• With noise emissions rated as low as 74 dBA, this generator falls within the typical noise range expected for devices of similar type and power. If noise emissions are one of your priorities, you may be interested in the Pulsar PGDA70BiSCO, one of the least noisy generators similarly powerful as this one, rated for 62 dBA.
• Compared to dual fuel devices of similar power, the H05751 stands out with one of the highest run times, lasting around 12 hours at 50% load.
• 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. Compared to its peers, this generator is not exactly fuel-efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.67 GPH at a 50% load. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the DuroMax XP7000iH, which has an impressively low fuel consumption of 0.38 GPH.
