  • Three phase output in a variety of voltages
  • High power nodes
  • Steel or aluminum enclosures (select units)
  • Continuous fuel with choice of LP or natural gas
  • Remote monitoring with GenLink® software available on 70 kW units and above

8-20 KW
Ideal for small to medium sized businesses or residences that require essential circuit coverage, the Guardian Series is designed specifically for high demand power generation needs. Features include:

  • Generac OHVI® engine provides reliability and long life
  • Continuous fuel with choice of LP or natural gas
  • Composite mounting pad included
  • External GFCI outlet on 17 & 20 kW
  • All-steel enclosures with RhinoCoat™ finish
  • Optional aluminum enclosure available on 17 kW, standard on 20 kW
  • Unbundled models also available
  • 8 - 17 kW systems include 100 amp NEMA 1 automatic transfer switch with load center for essential circuit coverage
  • 20 kW systems provide whole-house coverage
  • 20 - 60 kW systems provide automatic standby power protection for applications such as restaurants, gas stations, offices and large homes

Modular Power Systems (MPS)
The Generac Modular Power System is designed for large industrial applications that require superior system reliability and redundancy. Functions traditionally performed by numerous, multiple-manufacturer controllers are integrated into an exclusive Generac PowerManager® control system, providing a cost-effective, simple, single-source system with the benefits of parallel generation. Features include:

  • Scalable, flexible
  • Built-in redundancy
  • Reliability from redundancy of a multiple genset configuration
  • Cost effective - with prices comparable to, or less than, a large single genset
  • Built-in redundancy
  • Easy installation
  • Serviceable without critical system interruption


Gemini by Generac Power Systems features two gensets within a single, sound-attenuated, weather-resistant enclosure. As part of the Generac MPS system, up to seven Gemini gensets can be paralled without additional switchgear, for a total output as high as 7000 kW. Features include:
  • Twin gensets packaged in a compact 1000 kW unit
  • Critical load redundancy within a common generator platform
  • Single, electrical termination point for easy connection
  • Quiet, sound-attenuated operation


Bi-Fuel Generators increase run times, starting with diesel fuel and adding natural gas as load is applied. In an outage, Generac Bi-Fuel generators typically operate on a mixture of up to 90% natural gas and 10% diesel fuel; if the natural gas supply is interrupted, the generator switches automatically to 100% diesel–without a power drop during the transaction. Features of the system include:
  • Simultaneous use of diesel and natural gas
  • Reduced fuel storage with increased run times
  • Reduced cost per kilowatt, compared to larger, natural gas units
  • Redundant on-site fuel source
  • Available in the Generac Modular Power System
