Firman P03501 - Spec Breakdown

Description

Zoom on the Firman P03501

In summary, the Firman P03501 is a portable generator especially useful for:

• RV travellers looking for even more independence
• People occasionally participating in sporting competitions, open-air performances and outdoor festivals
• Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 P03501

The Firman P03501's design includes a gasoline-fueled 208 cc Firman Max-Pro Series OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3550W and also a peak wattage of 4450W.

Enjoying a noise rating of 67 dBA (less noisy than a normal conversation), this generator gets running thanks to a simple traditional pull-start mechanism.

Thanks to a fuel capacity of 5 gallons, the P03501 can operate for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).

The P03501 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)

120V 30A (L5-30R) receptacle

120V 30A (TT-30R) receptacle

This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The Firman P03501 has a conventional, open frame design, of the following dimensions: L24.8 x W21.7 x H21.7 in, which offers support and allows it 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 108.5 pounds. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.

Features

The P03501's control panel

The P03501's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, a light indicator allows you to instantly see if the oil level is too low.

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

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman P03501, the following accessories are also included: cover, oil, funnel and tool kit.

Emissions

The Firman P03501 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, which makes it suitable for use in forested areas.

The Firman P03501 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P03501 compare to generators of similar power (between 3500 and 4500 W).

• With a dry weight of 108.5 pounds, the Firman P03501 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
• Because this generator emits noise as low as 67 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 52 dBA.
• As the P03501 features an autonomy of around 14 hours at 50% load, it has a higher run time than an average generator of its power range. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Predator 4375, as it provides around 16 hours.
• Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Standing at an estimated 0.36 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you could look out for.
