Description

Zoom on the Pulsar PG4500iSR

In a nutshell, the Pulsar PG4500iSR is a portable inverter generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

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 Pulsar PG4500iSR in use

The Pulsar PG4500iSR

The Pulsar PG4500iSR's engine, 224 cc OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3700W and reaches a peak wattage of 4500W. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.

At a noise rating of 64 dBA (just slightly more noisy than background music), this inverter generator can be started via a conventional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). To add further convenience, the PG4500iSR can be remotely started (key fob included).

The PG4500iSR can operate for around 7 hours at 50% load with a full tank (fuel consumption around 0.46 GPH), due to its fuel capacity of 3.2 gallons.

As the PG4500iSR produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

It also sports 2 DC outlets: there's a 5V USB port allowing you to conveniently charge electronics such as mobile phones and tablets and a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease.

This Pulsar generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

Thanks to its closed inverter generator design (L26 x W24 x H28 in), the Pulsar PG4500iSR, is more esthetical than a typical, open frame generator. The design follows the contemporary trends and is perfect for recreationally generating power.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 102 pounds. However, its challenging mobility is solved by its set of 2 wheels (⌀5") and its telecospic handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Pulsar PG4500iSR

The PG4500iSR's control panel

The device’s light indicators will display if the oil level is too low, the generator is ready and the generator is on overload.

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

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Pulsar also included a key fob in the PG4500iSR's packaging.

Emissions

The Pulsar PG4500iSR is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Pulsar PG4500iSR versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Pulsar PG4500iSR compare to generators of similar power (between 3500 and 4500 W).

  • As its weight is 102 pounds, the Pulsar PG4500iSR falls in the expected weight range of the devices in the 3500-4500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • This inverter generator has a somewhat average expected noise for its power range, rated at 64 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 52 dBA.
  • Autonomy-wise, with around 7 hours on a full tank at a 50% load, the PG4500iSR is on the low end when compared to other generators of a similar power output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 4375, which is able to run for around 16 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. This inverter generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.46 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 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 3500-4500W generators, the Pulsar PG4500iSR is on the average side of the price range.

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