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.

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

The H05751, with a fuel capacity of 8 gallons, reaches a run time of around 12 hours at 50% load utilizing gasoline (fuel consumption around 0.67 GPH). Alternatively, it can reach a run time of around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH) with propane.

Since the H05751 has a somewhat high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel provides the upcoming 6 AC outlets:

Even though this Firman generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, as it features a twist-lock L14-30R receptacle, the H05751 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.

Portability

The Firman H05751 has a conventional, open frame design, of the following dimensions: L30.2 x W27.5 x H26.3 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

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. Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

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.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman H05751 also comes with several accessories, including: propane hose, funnel, oil and tool kit.

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 and therefore, can be used in forested areas.
