Features

  • QUIET-TEST™ SELF-TEST MODE: Runs at a lower, quieter RPM for a five-minute test, to ensure the system is running properly while consuming less fuel. Quiet-Test Self-Test Mode can be programmed to run weekly, biweekly, or monthly.
  • TRUEPOWER™ TECHNOLOGY: Delivers best-in-class power quality with less than 5% total harmonic distortion for clean, smooth operation of sensitive electronics and appliances.
  • CONTROLLER SELECTABLE FUEL: Fuel type selection using only the controller simplifies generator installation.
  • BUILT IN THE USA: Generac generators and engines are engineered and built in the USA* (*Assembled in the USA using domestic and foreign parts.)
  • SURGE CAPACITY: Designed to start and power large electrical loads for homes and businesses.
  • GENERAC DESIGNED & BUILT ENGINE: Purpose-built exclusively for generator use. Utilizes the first in class, dual-valve ultra-low pressure fuel delivery system and intelligent proprietary engine controls that manage over 100 performance functions to ensure peak efficiency in all temperature ranges and elevations.

Easily access information such as the current operating status and maintenance alerts. Users can connect an account to an authorized service dealer for fast, friendly, and proactive service. With Mobile Link, users are taken care of before the next power outage.
  • SOLID-STATE, FREQUENCY COMPENSATED VOLTAGE REGULATION: This state-of-the-art power maximizing regulation system is standard on all Generac models. It provides optimized FAST RESPONSE to changing load conditions and MAXIMUM MOTOR STARTING CAPABILITY by electronically torque matching the surge loads to the engine. Digital voltage regulation at ±1%.
  • SINGLE SOURCE SERVICE RESPONSE: from Generac’s extensive dealer network provides parts and service know-how for the entire unit, from the engine to the smallest electronic component.
  • GENERAC TRANSFER SWITCHES: Long life and reliability are synonymous with GENERAC POWER SYSTEMS. One reason for this confidence is the GENERAC product line is offered with its own transfer systems and controls for total system compatibility.
