Features

  • INFOHUB™ WIRELESS MONITORING: Lets you monitor your generator's status on your computer, tablet or smartphone sending maintenance reminders so your generator is always ready for the next power outage. Sold separately.
  • SYMPHONY® II POWER MANAGEMENT: Manages the distribution of power to your selected appliances automatically. Load management ensures the generator won't overload and shutdown so your family can continue with its daily routine. Transfer switch and modules sold separately.
  • BEST IN CLASS WARRANTY: Covers parts, labor and travel for the full-length of the warranty. See operator's manual or BRIGGSandSTRATTON.com for complete warranty details.
  • ASSEMBLED AND ENGINEERED IN THE USA: With domestic and foreign parts.
  • CORROSION RESISTANT DURABLE ENCLOSURE: Made from automotive-grade galvanneal steel to resist rust. Its advanced powder coat paint process results in years of protections against chips and abrasions.
  • FLEXIBLE PLACEMENT OPTIONS: With the ability to install your generator as close as 18 inches from your home.* (*Installations must strictly comply with all applicable codes, industry standards, laws, regulations and provided installation manual. Running engines give off carbon monoxide, an odorless, colorless, poisonous gas so it is important to keep exhaust gas away from any windows, doors, ventilation intakes or crawl spaces. The installation manual contains specific instructions related to generator placement in addition to NFPA 37, including the requirement that carbon monoxide detectors be installed and maintained in your home or business.)
  • SUPERIOR CUSTOMER SUPPORT: Our product is backed by our nationwide dealer network and call center experts.
  • FINANCING SOLUTION: We have partnered with Synchrony Bank to provide financing solutions that fit your needs. Special financing* is available on qualified Briggs & Stratton Standby Generators only with the Standby Power Credit Card. *Subject to credit approval. Minimum monthly payments required.
