Description
Zoom on the NorthStar e9250s
In short, the NorthStar e9250s is a portable generator adequately designed for:
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Homeowners in need of an emergency backup power for their essentials
- Professionals who want to be able to deliver results, even during a power failure
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.
Power & Run Time
Running on gasoline, the NorthStar e9250s utilizes a 420 cc NorthStar e420 OHV 4-stroke engine to deliver 120/240V, offering a running wattage of 7,250W and a starting wattage of 9,250W.
At a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator provides the choice between a standard recoil pull-rope starting mechanism or a convenient and efficient electric starter (battery included) for starting.
The Electronic Fuel Injection (EFI) system enhances the engine's reliability, lowers fuel consumption, improves startup, reduces servicing, boosts stale fuel resistance, and offers better altitude adaptability.
The e9250s can operate for around 10.8 hours at 50% load with a full tank (fuel consumption around 0.74 GPH), due to its fuel capacity of 8 gallons.
With a <5% Total Harmonic Distortion (THD), the e9250s delivers a clean sine wave—essential for safeguarding your delicate electronics when plugged into its AC outlets.
Outlets
The control panel features 8 AC outlets as follows:
This NorthStar generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, since it features a twist-lock L14-30R receptacle, the e9250s is tailored to be transfer switch ready, making it easy to connect it to your breaker box for home power support during outages.
Portability
With a size of L41 x W32 x H29 in, the NorthStar e9250s features an open frame design, providing stability and simplified maintenance access to components, enhancing air circulation. The featured design is ideal for the outdoors and all tough environments.
Though weighing 277 lbs, the generator remains classified as 'portable,' indicating its capability to be moved, though its weight could pose transport challenges. However, the constrained maneuverability is addressed with the assistance of its wheel kit (⌀10") and its folding handle, allowing for easy shifting once the generator is placed on the ground.
Features
The e9250s's control panel
To help you monitor the e9250s's status and activity, the unit's control panel is equipped with a digital display that provides extensive information on the generator (more information about it below).
As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during use.
It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.
Alongside the typical set of documentation and owner's manual (opens in a new tab) to assist with setup, NorthStar has included a funnel in the packaging of the e9250s.
Full-Featured Display
The excellent digital display
The unit is fitted with a colored, multi-function LCD display that offers simple, yet incredinbly exhaustive, at-a-glance monitoring. It features 3 screens:
- Home: Gives you information about the load that is connected, fuel level, estimated remaining run time, and total runtime of the generator
- Service: Displays maintenance intervals and the time remaining before each service is due
- Diagnostic: Provides various electrical data, such as voltage, current, and frequency
The NorthStar e9250s versus other generators
The following charts are provided to give you an idea of how some of the key specs of the NorthStar e9250s compare to generators of similar power (between 6500 and 7500 W).
- A weight of 277 lbs makes the NorthStar e9250s one of the heavier devices in the 6500-7500 rated wattage range. If weight matters to you, one of the champions in this power range is the Sportsman GEN85KIDF with only 133 pounds.
- Since the generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Champion 201175, whose lowest noise levels reach just 61 dBA.
- Compared to devices of similar power, the e9250s stands out with one of the higher run times, lasting around 10.8 hours at 50% load. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Predator 9000, with around 13 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.74 GPH at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Cummins Onan P9500df, with a fuel consumption of 0.6 GPH could be in your good books.
Price comparison
As you can see from these interactive charts, when compared to other 6500-7500W generators, the NorthStar e9250s 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.
