How the Symphony® II Power Management System Works

  1. During a power outage, the transfer switch senses it and notifies the generator to switch your home to backup power. This maintains your home’s fundamental power needs.
  2. The Symphony® II assesses its own power output and automatically turns on high-wattage appliances as power becomes available for use.
  1. The Symphony® II will wait for the excess power needs of robust appliances, like central AC units, to dissipate before turning on other high-wattage devices.
  2. The Symphony® II will automatically connect your home to utility power upon its restoration. The generator will then continue to monitor your home’s connection to this utility power to prepare for future outages.
