In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including 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 simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).

As for its running time, the H05751, 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 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH).

The quite high THD (<25%) of the H05751 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the upcoming 6 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 the H05751 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

The Firman H05751 has the following dimensions: L30.2 x W27.5 x H26.3 in. In combination with its conventional, open frame design, they provide support and allow 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 194.5 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit (⌀10") and its folding handle, which will ease its displacement, once it is on the floor.

Features

The H05751's control panel

The H05751 and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

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 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.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman H05751's package also includes these accessories: funnel, propane hose, tool kit and oil.

Emissions

The Firman H05751 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.
