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 a nutshell, the Powerhorse 9000ES is a portable generator mostly geared towards food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power.

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's core is the 420 cc (12.5 hp) OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 7250W and a peak wattage of 9000W.

The generator is rated for a noise of 75 dBA (just slightly more noisy than a vacuum cleaner). Its starting mechanisms include a conventional 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.

As the 9000ES produces a clean sine wave, with a <5% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the following 10 AC outlets:

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

Furthermore, it has 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease.

This Powerhorse 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 9000ES is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The dimensions of the Powerhorse 9000ES, which are L29.3 x W26.6 x H26.4 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 206 pounds. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the Powerhorse 9000ES

The 9000ES's control panel

The control panel of the 9000ES includes a handy voltmeter that allows you to easily monitor power output anytime, helpful for the monitoring of its status and activity.

In addition to this info, the device’s light indicator will display if its oil levels are insufficient.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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.

Along with the aforementioned features, from an accessory standpoint, the Powerhorse 9000ES's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

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.

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. If weight is your top priority, one of the champions in this power category is the Sportsman GEN85KIDF, weighing just 133 pounds.
  • As this generator can emit noise as low as 75 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are one of your priorities, you may be interested in the Powerhorse 7500i, one of the least noisy generators similarly powerful as this one, rated for 55 dBA.
  • As the 9000ES offers around 9.6 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Generac XC6500, boasting with around 14 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. 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Lifan ESI 7000iER-EFI. With a fuel consumption of as little as 0.38 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 6500-7500W generators, the Powerhorse 9000ES is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

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.
