Zoom on the Firman H03651

In summary, the Firman H03651 is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • 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, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Firman H03651 in use

The Firman H03651

The dual-fuel technology of the Firman H03651 allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3650W and a starting wattage of 4550W. If propane-powered, it gives 3300 rated watts and 4100 starting watts.

With a noise rating of 75 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 H03651, along with its 5 gallons fuel capacity, can run for around 14 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.36 GPH). If propane is used, it can operate for around 14 hours (on a 20 lbs tank - propane consumption around 0.34 GPH).

The H03651 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).

Outlets

The control panel features the following 4 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready.

Portability

The Firman H03651 has the following dimensions: L24.7 x W21.8 x H21.6 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 119.5 pounds. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀8") and its folding handle, once it is placed on the ground.

Features

Panel of the Firman H03651

The H03651's control panel

The H03651's status and activity may be monitored conveniently via the control panel, as it features 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.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman H03651 also comes with some accessories: propane hose, tool kit, oil and funnel are included.

Emissions

The Firman H03651 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

The Firman H03651 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H03651 compare to generators of similar power (between 3500 and 4500 W).

  • Since the generator weighs in at a dry weight of 119.5 lbs, the Firman H03651 belongs in the expected weight range for devices which can produce between 3500 and 4500 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 75 dBA can be judged as noisy. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • The H03651 provides a higher run time than similarly powerful devices, reaching around 14 hours at 50% load. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting with around 16 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator reaches an estimated fuel consumption of 0.36 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.
According to our stats, the following comparison is pretty popular: Firman H03651 vs Firman H03652.

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Firman H03651 is on the average side of the price range.
