Backup Generators are just that. They ready to run on demand, run intermittently and their output rating is higher

than that of a Prime power generator because the generator can be run "harder" for periods of time rather than

continuously at their prime rating.

Premium grade generators can be run both as backup or as prime power (see Prime). However, if your purpose is

backup and if you do not require the generator to run full time day in and day out, these more cost effective options

presented to you at the left side of this page are available.

A permanent hook-up to Natural Gas or Liquid Propane provides a safe, virtually continuous automatic fuel supply

eliminating the inconvenient connection steps required with portable generators.
