Description

Zoom on the Pulsar PG4500iSR

In summary, the Pulsar PG4500iSR is a portable inverter generator especially useful for:

  • RV travellers looking for even more independence
  • 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
  • Camping and tailgating hobbyists looking for a portable power source

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 Pulsar PG4500iSR in use

The Pulsar PG4500iSR

The Pulsar PG4500iSR houses a 224 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3700W along with a peak wattage of 4500W. In addition, the device is parallel capable (PGiPAIRB3 parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.

The inverter generator is rated for a noise of 64 dBA (just slightly more noisy than an office). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included). To add further convenience, the PG4500iSR can be remotely started (key fob included).

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

The PG4500iSR produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel provides the upcoming 3 AC outlets:

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

Furthermore, it has 2 DC outlets: there's a 5V USB port with which you may charge electronics, for example mobile phones or tablets, conveniently and a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries.

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.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 102 lbs make it incredibly difficult to manually lift and transport. However, this lack of maneuverability is compensated by its set of 2 wheels (⌀5") and its telecospic handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Pulsar PG4500iSR

The PG4500iSR's control panel

When the generator is on overload, its oil levels are insufficient and the generator is ready, you will be informed by the featured light indicators.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

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. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

Product Video

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 inverter generators of similar power (between 3500 and 4500 W).

  • At a weight of 102 pounds, the Pulsar PG4500iSR places in the expected weight range of the inverter generators in the 3500-4500 rated wattage range. 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.
  • Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 64 dBA can be judged as noisy. If noise emissions are one of your priorities, you may be interested in the Cummins Onan P4500i, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • As far as autonomy is concerned, providing around 7 hours of runtime with a full tank at a 50% load, the PG4500iSR falls into the low end in comparison with other inverters of a comparable power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Cummins Onan P4500i, as it provides around 15 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 rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.46 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Cummins Onan P4500i, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W inverter 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.
