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 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

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 Powerhorse 9000ES in use

The Powerhorse 9000ES

The Powerhorse 9000ES is powered by a 420 cc (12.5 hp) OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 7,250W as well as a peak wattage of 9,000W.

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 convenient and easy-to-use electric starter (battery not included).

With a full tank, the 9000ES can operate for around 9.6 hours at 50% load (fuel consumption around 0.69 GPH), thanks 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 Distortion (THD).

Outlets

The control panel includes the following 10 AC outlets:

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

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

Even if this Powerhorse generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, because the 9000ES is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The Powerhorse 9000ES has a conventional, open frame design, of the following dimensions: L29.3 x W26.6 x H26.4 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 206 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Powerhorse 9000ES

The 9000ES's control panel

The 9000ES and its control panel include a handy voltmeter that allows you to easily monitor power output anytime. This feature comes handy when monitoring its status and activity.

In addition to this info, a light indicator allows you to instantly see if the oil level is too low.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

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 and therefore, can be used 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).

  • Having a dry weight of 206 lbs, the Powerhorse 9000ES belongs in the expected weight range for generators which produce 6500 to 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.
  • As this generator has its lowest possible noise of 75 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If you are concerned with noise, check out the Powerhorse 7500i, which is one of the least noisy generators in its power range, with a noise rating of just 55 dBA.
  • Given that the 9000ES reaches an autonomy of around 9.6 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. 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.
  • 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. Standing at an estimated 0.69 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV7500, with a fuel consumption of 0.45 GPH could be in your good books.

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.
