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

Thanks to its dual-fuel technology, the Firman H05751 delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 5700W and a peak wattage of 7125W. When propane-powered, it has 5700 rated watts and 7125 peak watts.

At a noise rating of 74 dBA (just slightly more noisy than a shower), this generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included).

With a fuel capacity of 8 gallons, the H05751 can operate for around 12 hours at 50% load using gasoline (fuel consumption around 0.67 GPH), or for around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH) using propane.

The powering of sensitive electronic devices with the H05751 is not recommended due to its relatively high THD (<25%).

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 dimensions of the Firman H05751, which are L30.2 x W27.5 x H26.3 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

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 194.5 lbs. 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 control panel of the H05751 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

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: tool kit, propane hose, funnel 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.
