Description

Zoom on the NorthStar e18000s

In short, the NorthStar e18000s is a powerful portable generator adequately designed for:

  • Professionals who want to ensure that a power failure will not prevent them from working
  • Homeowners who wish to power almost all appliances in their house under any circumstances

Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.

Power & Run Time

The NorthStar e18000s in use

The NorthStar e18000s

NorthStar e18000s is equipped with a 824 cc NorthStar e825 OHV 4-stroke engine, running on gasoline and providing 120/240V, boasting a running wattage of 15,000W alongside a starting wattage of 18,000W.

With a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), the generator features a convenient and efficient electric starter (battery included).

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.

Featuring a 12 gallons fuel tank, the e18000s can provide power for around 7.9 hours at 50% load on a full tank (with fuel consumption averaging 1.52 gallons per hour).

Thanks to its low <5% Total Harmonic Distortion (THD), the e18000s produces a clean sine wave output, making it safe for your sensitive electronics when utilizing the AC outlets.

Outlets

The control panel features the following 9 AC outlets:

Three Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 60A (14-60R) receptacle

This NorthStar 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, due to the featured twist-lock L14-30R receptacle, the e18000s is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

Measuring L43 x W36 x H35 in, the classic open frame construction of the NorthStar e18000s provides stability while enabling convenient maintenance access to components and adequate air cooling. The device has been designed for tough environments and demanding outdoor use.

While weighing 423 lbs, the generator is classified as 'portable,' indicating its mobility, albeit its heftiness may limit portability in specific situations. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.

Features

Panel of the NorthStar e18000s

The e18000s's control panel

To help you monitor the e18000s'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 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.

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.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, NorthStar also included a funnel in the e18000s's packaging.

Full-Featured Display

The Home, Service, and Diagnostic screens of the 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 e18000s versus other generators

The following charts are provided to give you an idea of how some of the key specs of the NorthStar e18000s compare to generators of similar power (between 14000 and 20000 W).

  • In terms of its dry weight, the NorthStar e18000s stands at only 423 lbs, meaning that is one of the lighter devices of the 14000-20000 rated wattage category In terms of weight, one of the champions in their power range is the Westinghouse WGen14500TFc, standing at just 348.3 lbs.
  • At just 74 dBA rated noise level, this generator is positioned as one of the quietest choices among devices delivering similar power.
  • The e18000s's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 7.9 hours at 50% load on a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse WGen20000, reaching around 11 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. As this generator uses an estimated 1.52 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you are concerned with gasoline efficiency, having a fuel consumption of just 1.05 GPH, the Westinghouse WGen14500TFc is a device you could look out for.

Price comparison

As you can see from these interactive charts, when compared to other 14000-20000W generators, the NorthStar e18000s 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.
