Firman P03602 Spec Review

Description

Zoom on the Firman P03602

In summary, the Firman P03602 is a portable generator especially useful for:

• RV travellers wishing to enhance their freedom and nomad lifestyle
• Occasional participants of outdoor events, competitions, concerts and festivals
• Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 P03602

The Firman P03602's engine, 208 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3650W and reaches a peak wattage of 4550W.

The generator is rated for a noise of 67 dBA (less noisy than background music). Its starting mechanism is based on a simple traditional pull-start mechanism.

Thanks to a fuel capacity of 5 gallons, the P03602 can operate for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).

Since the P03602 has a somewhat high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel includes the following 4 AC outlets:

Duplex 120V 20A (5-20R)

120V 30A (L5-30R) receptacle

120V 30A (TT-30R) receptacle

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

Portability

The Firman P03602 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 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 108.5 lbs. 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 P03602's control panel

The P03602's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

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

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman P03602 also is packed along with the following accessories: funnel, oil and tool kit.

Emissions

The Firman P03602 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor and therefore, can be used in forested areas.

The Firman P03602 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P03602 compare to generators of similar power (between 3500 and 4500 W).

• With a dry weight of 108.5 pounds, the Firman P03602 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
• As this generator can emit noise as low as 67 dBA, it finds itself in the average expected noise for this kind of power. For those who are looking for a less noisy device, we suggest the Cummins Onan P4500i. With just 52 dBA, it is one of the most quiet devices in this power range.
• The P03602 provides a higher run time than similarly powerful devices, reaching around 14 hours at 50% load. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, 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. 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
