Briggs & Stratton Symphony Choice Power Management

The Briggs & Stratton Symphony® Choice Power Management is a smart load-management system that works with PowerProtect™ standby generators and a standard Automatic Transfer Switch (ATS) to keep your most important appliances on — without oversizing the generator. It continuously monitors whole-home demand, then prioritizes circuits so essential loads get power first while preventing overloads or backfeed risks.

• Smart, prioritized loads — Assign priority to large appliances (A/C, oven, dryer, sump pump, etc.) so essentials stay on during an outage.
• Protects the system — Actively manages demand to help prevent generator overloads and electrical backfeeds.
• Pairs with PowerProtect™ 10–26 kW generators — Use for managed whole-home backup with 10–12 kW units; optional with 17–26 kW units.
• All-in-one simplicity — Kit integrates with the revised, improved standard ATS that ships with PowerProtect™ home standby generators.
• Between-stud mounting — Standard ATS footprint installs cleanly between studs for a tidy, low-profile setup.
• Flexible for new or existing installs — Add power management during a new install or retrofit it to an existing generator system.
• Available ATS ratings & models — 100 A (71210), 150 A (71250), 200 A (71270), 200 A with 10-Year Warranty (71272), 100 A CA (71130), 200 A CA (71230).
• Long coverage — 6-Year warranty on the standard ATS.

Seamless, automatic protection

During an outage, the generator starts and the ATS transfers power to your home. Symphony® Choice senses total demand in real time and temporarily locks out lower-priority loads so critical circuits stay powered. As capacity frees up, deferred loads are automatically restored — no manual switching required.

All-in-one simplicity

By pairing load management with the standard ATS, you get fewer SKUs to stock and a cleaner install. Homeowners can often choose a smaller generator while still enjoying whole-home coverage thanks to priority control.

Adaptable for any home

Whether you’re installing a new PowerProtect™ generator or upgrading an existing system, Symphony® Choice drops in easily. Two sets of lockout contacts give installers flexibility to manage high-draw appliances.

Installer-friendly details

The updated standard ATS is designed for fast, clean wiring and secure between-stud mounting. A compact Symphony® Choice control board simplifies placement in tight spaces.
