Model PG4500iSR | 4,500W Starting / 3,700W Running | 224cc OHV | Remote + Electric Start | ~64 dB | RV-Ready TT-30R | CARB & EPA Compliant
The Pulsar PG4500iSR is a portable inverter generator delivering 4,500 starting watts and 3,700 continuous running watts from a 224cc 4-stroke OHV air-cooled engine — engineered for RV travel, campsite use, jobsite power, and residential backup applications where quiet, clean inverter-grade AC output and the convenience of remote start matter. Operating at approximately 64 dB, the PG4500iSR runs quietly enough for campsite environments while providing enough power to start and run an RV air conditioner (with soft-start kit), refrigerator, lights, electronics, and power tools simultaneously. Three start modes — remote key fob (up to ~80 ft), electric push-button, and recoil pull — ensure reliable starts in all conditions, while a 3.2-gallon fuel tank supports up to 7–11 hours of runtime at 50% load. A TT-30R 30A RV outlet, 20A duplex, 12V DC, and USB-A port cover every connection need, and parallel capability with Pulsar's PGiPAIR/PGDiPAIR kits doubles total output when a second compatible unit is available. CARB and EPA compliant, backed by a 3-year limited warranty.
Remote Start Up to ~80 Feet — Three Start Modes: The PG4500iSR includes a remote key fob that starts or stops the generator from up to approximately 80 feet away — a practical advantage when the generator is stored in a compartment, outside the RV, or at a distance on a jobsite — backed by an electric push-button start for convenient close-range starting and a recoil pull-start as a no-fail mechanical backup when the battery is depleted, ensuring you always have a reliable way to start the generator regardless of conditions or battery state.
RV-Ready TT-30R Outlet + Full Outlet Array: A dedicated 120V 30A TT-30R RV outlet makes the PG4500iSR a direct plug-in power source for standard RV shore power connections — capable of starting an RV rooftop air conditioner when paired with a compatible soft-start kit — while the additional 120V 20A duplex (5-20R), 12V DC 8A output, and 5V/2.1A USB-A port simultaneously serve tools, appliances, battery chargers, and device charging across a single generator, eliminating the need for adapters or power strips for most common RV and campsite loads.
Quiet ~64 dB Inverter Operation — Campsite Friendly: The PG4500iSR's inverter-based power generation produces clean, stable AC output with low total harmonic distortion suitable for sensitive electronics including laptops, TVs, routers, and battery chargers — while its ~64 dB operating noise level keeps it within typical campsite noise guidelines and significantly quieter than conventional open-frame generators of comparable output, making it a practical choice for campgrounds, RV parks, and residential neighborhoods where generator noise is a meaningful consideration.
Parallel Capable — Double Output with a Second Unit: Using Pulsar's compatible PGiPAIR or PGDiPAIR parallel connection kit, two PG4500iSR units can be linked together to combine their output — effectively doubling available running wattage for high-demand applications such as larger RV systems, multi-tool jobsites, or extended home backup scenarios — without requiring a larger, heavier single generator, and preserving the portability and storage advantages of two separate compact units over one large conventional generator.
CARB & EPA Compliant — 3-Year Limited Warranty: The PG4500iSR meets both California Air Resources Board (CARB) and federal EPA emissions standards — making it legal for sale and use in all 50 US states including California — and is backed by a Pulsar 3-year limited warranty covering manufacturing defects in materials and workmanship, providing a meaningful assurance of quality and long-term support for a generator that may serve as critical backup power for years after purchase.
The PG4500iSR's 224cc 4-stroke OHV air-cooled engine drives an alternator that produces raw AC power, which is then rectified to DC and re-inverted to clean, stable 120V/60Hz AC output through the inverter module — a two-stage conversion process that produces lower total harmonic distortion than conventional generators and allows the engine speed to vary with load rather than running at fixed 3,600 RPM, reducing fuel consumption at partial loads and contributing to the lower noise level during light-duty operation. The 3.2-gallon fuel tank provides up to 7–11 hours of runtime at 50% load, and the included wheel kit makes the ~102–109 lb unit manageable for repositioning without a second person.
224cc OHV Engine & Inverter Power Generation: The overhead-valve (OHV) engine design delivers better fuel efficiency, lower emissions, and longer service intervals compared to side-valve engines of equivalent displacement — with the air-cooled configuration eliminating the complexity and maintenance requirements of liquid-cooled systems while providing reliable thermal management across the full operating temperature range the generator will encounter in RV travel, outdoor jobsite, and residential backup applications.
What It Can Power: At 3,700 running watts, the PG4500iSR comfortably sustains a residential refrigerator (150–400W running), LED lighting, router, TV, multiple laptop chargers, and a window AC unit simultaneously — with the 4,500W starting capacity handling the high inrush current of motor loads like refrigerator compressors, power tools, and RV rooftop air conditioners (with a soft-start kit reducing the startup surge), making it a capable single-source power solution for most RV electrical systems and common home backup scenarios during outages.
Parallel Operation & Accessories: When connected via the Pulsar PGiPAIR or PGDiPAIR parallel kit to a second compatible inverter generator, the combined system output scales proportionally — with the parallel kit providing a single output interface that distributes combined power across a 30A or 50A connection point for high-demand RV systems or jobsite distribution. Recommended accessories include a 30A RV power cord (TT-30P to RV panel), an in-line surge protector to guard sensitive RV electronics and appliances, and a parallel kit matched to the output configuration required by the application.
