Description

This Powerhorse Portable Generator with Electric Start combines 9,000 Watts of clean electricity, electric start convenience and a full bank of outlets in one rugged, portable package. 100% copper-wound head and low harmonic distortion (less than 5%) provide safe operation of sensitive electronics.

Zoom on the Powerhorse 9000ES

In summary, the Powerhorse 9000ES is a portable generator especially useful for:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners in need of an emergency backup power for their essentials

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 Powerhorse 9000ES in use

The Powerhorse 9000ES

The Powerhorse 9000ES houses a 420 cc (12.5 hp) OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 7250W along with a peak wattage of 9000W.

The generator is rated for a noise of 75 dBA (just slightly more noisy than a shower). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery not included).

The 9000ES can operate for around 9.6 hours at 50% load with a full tank (fuel consumption around 0.69 GPH), due to its fuel capacity of 6.6 gallons.

Delicate electronics can be plugged in an AC outlets safely, as the 9000ES generates a clean sine wave, reaching a <5% Total Harmonic Disruption (THD).

Outlets

The control panel features the upcoming 10 AC outlets:

Four Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

Additionally, it features 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which charging your batteries is made easy.

This Powerhorse 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, due to the featured twist-lock L14-30R receptacle, the 9000ES is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The Powerhorse 9000ES has the following dimensions: L29.3 x W26.6 x H26.4 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 206 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Powerhorse 9000ES

The 9000ES's control panel

The 9000ES's control center features a handy voltmeter that allows you to easily monitor power output anytime to aid you with the monitoring of its status and activity.

In addition to this info, a light indicator serves to show you when its oil levels are insufficient.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Besides the features previously mentioned, accessory-wise, the Powerhorse 9000ES comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.

Emissions

The Powerhorse 9000ES is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, which makes it suitable for use in forested areas.

Product Video

The Powerhorse 9000ES versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powerhorse 9000ES compare to generators of similar power (between 6500 and 7500 W).

  • Since the generator weighs in at a dry weight of 206 lbs, the Powerhorse 9000ES belongs in the expected weight range for devices which can produce between 6500 and 7500 rated watts. Regarding dry weight, one of the champions in the same power range is the Sportsman GEN85KIDF, with a dry weight of only 133 lbs.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 75 dBA can be judged as noisy. For those who are looking for a less noisy device, we suggest the Powerhorse 7500i. With just 55 dBA, it is one of the most quiet devices in this power range.
  • The 9000ES, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 9.6 hours at a 50% load and a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Generac XC6500E, reaching around 14 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. As this generator uses an estimated 0.69 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to further improve in the area of fuel efficiency, the Lifan ESI 7000iER-EFI, which boasts with a gas consumption of only 0.38 GPH, may be the right generator for you.

The bottom line

STRENGTHS:
  • Electric start
  • Clean sine wave
AVERAGE SPECS:
  • Decent weight (206 lbs)
  • Decent run time
  • Decent fuel efficiency
WEAKNESSES:
  • No 50-amp output
  • Battery not included
  • No remote start
  • Not CARB-compliant
  • On the noisy side (75 dBA)

What does the throttle control switch do? Should I have it on? Couldn’t find information in manual. I have the powerhorse 9000E (Asked October 30, 2020)

This feature senses the load on the generator. With no load on the generator the engine speed drops to idle, which saves fuel and lengthens engine life. When a load is applied, the engine speed returns to maximum RPMs. Turning the switch off disables the sensing device and the generator will run at maximum RPM whether or not a load is applied.

Will it run a hot water heater (Asked November 14, 2020)

Most likely, yes. But it's always better to check your appliance's data plate to know its actual power needs.

How do I get a replacement throttle control switch for 9000? (Asked March 17, 2021)

Replacement parts can be ordered from Northern Tool.

Is this an inverter generator? (Asked March 18, 2022)

The unit is not an inverter generator, but it has a low THD.
