Briggs & Stratton Develops New P4500 PowerSmart Series™ Inverter For RV Market

New inverter generator features innovative CO Guard™ Technology

MILWAUKEE, Wisconsin (April 30, 2019) – RV enthusiasts will look no further for an efficient and innovative product to power their traveling adventures with the new Briggs & Stratton® P4500 PowerSmart Series inverter generator. The new unit is equipped with CO Guard Carbon Monoxide Shutdown technology, an industry-leading technology designed to shut down the generator if harmful levels of CO accumulate in the generator's operating area.

"Avid RV travelers told us they're not happy with current on-board generators because they're very loud and use a lot of fuel," said Michael Fritz, senior global product manager for Briggs & Stratton portable power. "That same group told us that they are impressed by the quietness of the P4500, which runs 60% quieter1 than a standard generator. It also provides up to 16 hours of runtime2 and produces the power of a typical 30A campground utility connection."

Engineered to be compact, lightweight, and quiet, the new P4500 inverter generator has a protective hard shell to safeguard the unit from dirt and debris, never-go-flat wheels, and a telescoping handle to make moving it around an RV site a breeze. A convenient push-button electric start turns on the Briggs & Stratton 224cc engine to deliver 4500 starting watts3 and 3700 running watts4. Its multifunctional digital display panel allows operators to monitor power usage, fuel level and run time. Four household 120-volt outlets, one 120-volt 30-amp RV outlet, and two USB adaptors offer the operator flexibility to power a combination of lights, kitchen appliances, and smart devices. Innovative inverter technology automatically adjusts the engine speed to lower the noise level and reduce fuel consumption. The P4500 also features Quiet Power Technology® and is backed by a three-year limited warranty5.

Briggs & Stratton's patent-pending CO Guard technology monitors the presence of carbon monoxide and will shut down the generator if harmful levels accumulate in the generator's operating area. An LED light display on the unit will alert the user of the shutdown trigger, and a nearby instruction decal will provide guidance on next steps. Operators will not be able to continue with normal power until CO Guard's sensor has determined the presence of CO has diminished.  

All portable generators, including inverter generators, emit carbon monoxide and are dangerous if not operated properly. The only safe place to operate a portable generator is outside and at least 20 feet from any RV, tent or home with exhaust pointing away.

This is the latest addition to the Briggs & Stratton PowerSmart Series of inverter generators, which are designed for any outdoor recreation activity where a reliable and quiet power source is expected.
