Symphony II®

Thanks to Symphony® II Power Management System, a smaller home generator system by Briggs & Stratton can meet all your needs and save you money in the process.

Now 60% Quieter

Powered by our high-quality Vanguard engine, improved muffler design and re-engineered alternator intake ducting, the new 12kW is 60% quieter than our old 12kW.

Streamlined, Space-Saving Design

With the streamlined, compact design, the new 12kW is 50% smaller than our previous 12kW generator.

Durable Enclosure

Designed to weather the elements, the system’s enclosure is made from automotive-grade Galvanneal steel to resist rust. Its advanced powder coat paint process results in years of protection against chips and abrasions.

Flexible Placement

Have a tight lot line? Worried about your curb appeal? Install your generator as close as 18″ from your home. Our generators are in compliance with the stringent National Fire Protection Agency 37 standard.
