  • Our Quietest Generator Yet

    Featuring unique air-flow technology, our 20kW1 standby generator is our quietest generator yet. And because it is 50% quieter than many portable generators, this 20kW1 is the best choice to keep your neighbors happy.

  • Natural Gas Pressure Requirements

    Rated for operation in areas with low natural gas pressure. This standby generator can operate at 5'' to 7'' water column.

  • Designed Around Your Protection3

    Thoroughly tested against rigorous National Fire Protection Agency standards, this is the only 20kW1 standby generator with an all-steel enclosure and all-steel base, so it can withstand temperatures more than double that of aluminum and far beyond that of plastic. With an external, automatic gas shut-off valve, low pressure regulator and the only internal thermal protection system found on any 20kW1 standby in the industry, we’ve raised the bar on protecting your home and family.

  • High-Performance Engine

    Proven to deliver non-stop reliability, our 20kW standby generators are powered by premium-grade Vanguard™ engines that are developed for tough commercial applications.

  • Symphony® II Power Management

    The patented Symphony® II power controls provide a managed power solution that gives you access to every powered item in your house, just not at the same time. By using power management modules, appliances become prioritized and turn on and off based on need and the electrical load placed on the standby generator.

    Includes a wireless monitor for inside your home, so you know your backup generator is working without having to go outside.
