Symphony II Power Management

Whole-house power is now a whole lot more affordable with Briggs & Stratton’s new Symphony® II Power Management system. As the most customizable Power Management system anywhere, this patented technology is the easiest way to give your family unprecedented peace of mind and protection during a power outage.


What Symphony® II Does

Symphony® II Power Management automatically balances the power needs of your home’s electrical loads — including high-wattage items like air conditioning units, electric stoves and electric dryers — to give your family uninterrupted, whole-house power with a more affordable home generator.


How Symphony® II Works

With Symphony® II Power Management, you can select up to eight high-wattage appliances based on your family’s specific power needs. It then manages the distribution of power from the generator to those appliances — automatically. This load management ensures the generator won’t overload so your family can continue with its daily routine uninterrupted.


Additionally, the Symphony® II Power Management transfer switch is wired into your home’s existing wiring, where it monitors your home’s electrical circuits, so you save even more on the cost of installation.


How You Save with Symphony® II

Symphony® II Power Management lets you purchase a smaller, more affordable home generator system while maintaining the comfort of whole-house power. With Symphony® II Power Management, you’ll benefit from:


·         A reduced initial investment

·         Lower fuel costs

·         Lower installation costs
