Residential Home Standby Emergency Power Generator Sets

Natural Gas Home Standby Generators

Cummins Onan diesel generator setClean, quiet, and neighborhood friendly, all residential generator models run on either natural gas or propane.

Why use an residential generator instead of a portable for home standby emergency power? A permanent residential generator set includes many additional features, including a more complex control system, and usually has more power capacity. It also has a weather protective enclosure that is also designed for sound reduction.

Advantages of using natural gas to fuel your home standby system:

  • Usually unlimited fuel source - refueling not necessary
  • Clean burning
  • Almost always available during power outages
  • No unsightly tank required

Disadvantages of using natural gas to fuel your home standby system:

  • May be unavailable during natural disasters (earthquakes, etc.)
  • Lower power output (30% less BTU's per unit than gasoline)
  • Larger tanks are not aesthetically pleasing (unsightly)
  • Fuel system plumbing results in higher installation cost
  • Not available in many areas
