Description

The FIRMAN H07552 generator features 9,400 starting Watts and 7,500 running watts (8,450/6,750 LPG). Power is supplied by our Max Pro Series 439cc FIRMAN engine which runs cool and efficient thanks to its Phoenix Fat Head Block. Our Whisper Series muffler keeps the H07552 quieter and efficient, and our spark arrester has been approved by the USDA Forest Service. The industry-leading 8 gallon fuel capacity provides a whopping 12 hours of run time. Starting is as simple as the push of a button on the H07552. (source: Firman)

Zoom on the Firman H07552

In a nutshell, the Firman H07552 is a portable generator mostly geared towards:

  • Food truck owners and people participating in outdoor fairs, festivals or events
  • Professionals who want to ensure that a power failure will not prevent them from working

In the following paragraphs, we shall explore the power characteristics, available outlets, portability and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Firman H07552 in use

The Firman H07552

Thanks to its dual-fuel technology, the Firman H07552 delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 7500W and a peak wattage of 9400W. When propane-powered, it has 6750 rated watts and 8450 peak watts.

With a noise rating of 74 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).

With a fuel capacity of 8 gallons, the H07552 can operate for around 12 hours at 50% load using gasoline (fuel consumption around 0.67 GPH), or for around 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH) using propane.

The H07552 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).

Outlets

The control panel features the following 5 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

This Firman generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, as the H07552 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 Firman H07552 has a conventional, open frame design, of the following dimensions: L29.8 x W26.4 x H26.3 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy 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 212 pounds. Never less, it can still be moved quite conveniently with the help of a wheel kit (⌀10") and a folding handle, once it is placed on the ground.

Features

Panel of the Firman H07552

The H07552's control panel

The control panel of the H07552 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of 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.

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.

Along the basic documentation and a user manual, useful for starting the generator right away, the Firman H07552's package also includes these accessories: tool kit, funnel, oil, cover and propane hose.

Emissions

The Firman H07552 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, which makes it suitable for use in forested areas.

Product Video

The Firman H07552 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H07552 compare to generators of similar power (between 7000 and 8000 W).

  • As its weight is 212 pounds, the Firman H07552 falls in the expected weight range of the devices in the 7000-8000 rated wattage category. In terms of weight, one of the champions in their power range is the Predator 8750, standing at just 183 lbs.
  • Because this generator emits noise as low as 74 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 WEN GN9500 with only 64 dBA.
  • As the H07552 features an autonomy of around 12 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 9000, as it provides around 13 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. With an estimated gasoline consumption of 0.67 GPH (gallon per hour) at 50% load, this generator is among the more fuel efficient of the products in the above-mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Predator 8750. With a fuel consumption of as little as 0.55 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this dynamic chart, when compared to other 7000-8000W generators, the Firman H07552 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

Questions & Answers

QOf the 4 outlets is only one a GFCI outlet? So can a non-GFCI transfer switch be connected to the 120/240 V 30 amp outlet without tripping the generator breaker which happens with a GFCI outlet? (Asked July 10, 2019)

ACorrect. Only the 5-20R duplex is GFCI

QCan it run on a homes in ground propane supply (Asked August 15, 2019)

ABelow-ground propane is no different than above-ground propane. So there's no reason why it wouldn't work.

QI have two circuit boxes I would like to power and selectively/manually pick and chose from. Can I use the 50 amp and 30 amp plugs simultaneously to drive both boxes (one for each) with attention given to the max loads of the generator? (Asked November 06, 2019)

AYou can absolutely use these two outlets simultaneously.
