Description
Zoom on the Firman WT05571
In a nutshell, the Firman WT05571 is a portable inverter generator mostly geared towards:
- RV travellers looking for even more independence
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Food van owners who know that just a short power outage could lose them hundreds of dollars
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- 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.
Power & Run Time
The Firman WT05571
The Firman WT05571 delivers 120/240V and benefits from a tri-fuel technology that allows it to run on gasoline, propane, or natural gas. When gasoline-powered, it enjoys a running wattage of 5,500W and a peak wattage of 6,850W. When propane-powered, it benefits from 5,000 rated watts and 6,250 peak watts. Its natural gas operation offers 4,500W of rated wattage and 5,500W of starting wattage. Furthermore, its parallel capability (parallel kit not included) allows for increasing of power output when connected to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.
Enjoying a noise rating of 67 dBA (less noisy than an office), this inverter generator offers the versatility of starting with either a classic hand-operated recoil starting mechanism or a user-friendly and hassle-free electric starter (battery included).
Concerning its running time, the WT05571, featuring a 5.3 gallons fuel tank, can continuously run for up to 14.5 hours with a full gasoline tank (consuming fuel at approximately 0.37 gallons per hour). Alternatively, when utilizing propane, it offers up to 9.5 hours (estimation based on a 20 lbs tank - propane consumption around 0.49 GPH) of runtime.
The <3% Total Harmonic Distortion (THD) of the WT05571 ensures a clean sine wave output, providing a secure power source for your sensitive electronics through its AC outlets.
Outlets
The control panel includes the following 5 AC outlets:
Additionally, it features 2 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle offering a convenient battery charging option and a 5V USB port (USB-C) with which you may charge electronics, for example mobile phones or tablets, conveniently.
Featuring a TT-30R receptacle (TT for 'Travel Trailer'), this Firman generator is RV Ready, designed specifically for use with recreational vehicles. In addition, since it features a twist-lock L14-30R receptacle, the WT05571 is tailored to be transfer switch ready, making it easy to connect it to your breaker box for home power support during outages.
Portability
As an inverter generator, the Firman WT05571 showcases a closed design (L27.6 x W21.3 x H22.6 in), enhancing aesthetics and ensuring quieter operation compared to conventional, open frame models. This modern design aims to provide an ideal power solution to recreational users.
While technically classified as 'portable' due to its ability to be moved, the 131.4 lbs of this generator make manual lifting and transportation incredibly difficult. However, the limited maneuverability is remedied with its set of 2 wheels (⌀8") and its folding handle, facilitating convenient shifting once the generator is positioned on the ground.
Features
The WT05571's control panel
Designed with a digital data center, the control panel of the WT05571 grants you access to crucial data on the lifetime run hours, fuel level, remaining run time, power output, voltage and frequency, ensuring practical monitoring of its status and activity.
As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.
The WT05571 also benefits from Firman’s CO Alert carbon monoxide shutdown, which automatically shuts down the engine when harmful levels of carbon monoxide accumulate around the generator or a CO Alert fault occurs.
In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the Firman WT05571 also includes several accessories: funnel, oil, tool kit and propane hose.
Product Video
The Firman WT05571 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman WT05571 compare to inverter generators of similar power (between 5000 and 6000 W).
- As its weight is 131.4 pounds, the Firman WT05571 falls in the expected weight range of the inverters in the 5000-6000 rated wattage category. if you wish to prioritize weight, the Pulsar PGX60BiSRCO is one of the top contenders in its power category, weighing only 93.5 pounds.
- When compared to other units producing a similar running wattage, this inverter generator and its lowest emitted noise of 67 dBA stand out for being on the louder side. If you wish to prioritize minimal noise, the Honda EU7000iS stands out as one of the quietest options among generators of similar power, with a rating of 52 dBA.
- With a runtime of up to 14.5 hours under a 25% load on a full tank, the WT05571 falls within the average autonomy range among the inverter generators of a similar power. If you wish to prioritize autonomy, the Champion 201532 shines as one of the top contenders, offering one of the highest run times among generators with similar power output, totaling up to 18 hours.
- While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. This inverter generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.37 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the DuroMax XP7000iHT, with a fuel consumption of 0.19 GPH could be in your good books.
Price comparison
As you can see from these interactive charts, when compared to other 5000-6000W multi-fuel generators, the Firman WT05571 is on the expensive side of the price range.
While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
