Features

Enclosure

  • ALUMINUM WEATHER PROTECTIVE ENCLOSURE: Ensures protection against mother nature. Electrostatically applied textured epoxy paint for added durability.
  • ENCLOSED CRITICAL GRADE MUFFLER: Quiet, critical grade muffler is mounted inside the unit to prevent injuries.
  • SMALL, COMPACT, ATTRACTIVE: Makes for an easy, eye appealing installation.
  • SAE: Sound attenuated enclosure ensures quiet operation.

Features

  • The best liquid cooled engine packs more power into a smaller footprint - ideal when space is a premium. The neutral styling, color and small footprint fits unobtrusively into landscaping. Clean burning, continuous fuel choice of natural gas to LP.
  • TRUE POWER™ TECHNOLOGY: Delivers best-in class power quality with less than 5% total harmonic distortion (THD) for clean, smooth operation of sensitive electronics and appliances.
  • EVOLUTION™ CONTROLLER: A cutting-edge, intuitive control. The Evolution controller features a multilingual, two-line LCD text display with color-coded, backlit buttons. It has received upgrades, including USB flash capability, smart battery charging, voltage adjustment, and backlit membrane pad-style buttons.
  • 5-YEAR LIMITED WARRANTY WITH EXTENDED WARRANTY OPTIONS AVAILABLE: We are proud of our innovative product design, high quality and first-class reliability so we stand behind them with a strong 5, 7 or 10-year limited warranty.
  • CAN BE INSTALLED JUST 18" FROM A STRUCTURE: Capability to be installed 18 inches away from a structure, ideal for areas with tight lot lines. Generac is the only manufacturer of standby generators to have 18” offset on most of its residential lineup.
  • TOUGH, DURABLE All-ALUMINUM ENCLOSURES: Our RhinoCoat™ powder-coated finish helps make corrosion-resistant aluminum perfect for all weather conditions.
  • QUIET-TEST™: All backup generators run a weekly test to ensure the system is running properly. Thanks to Quiet-Test, your Protector Series home generator runs its self-test at a lower, quieter RPM, which can be programmed to run weekly, bi-weekly, or monthly.
  • MOBILE LINK™ CONNECTIVITY: Mobile Link™ Connectivity allows you to monitor the status of your generator from anywhere in the world using a smartphone, tablet or PC. Easily access information such as the current operating status and the generator's maintenance schedule.
  • ADDITIONAL FEATURES: Improved stub ups and electrical connection access decrease installation costs. All connections are dual conductor rated, and the implementation of quick connects for the control wires, completely eliminates the need for crimping or lugging.Improved customer connection access, which decreases installation costs.
  • INNOVATIVE DESIGN & PROTOTYPE TESTING: are key components of GENERAC’S success in “IMPROVING POWER BY DESIGN.” But it doesn’t stop there. Total commitment to component testing, reliability testing, environmental testing, destruction and life testing, plus testing to applicable CSA, NEMA, EGSA, and other standards, allows you to choose GENERAC POWER SYSTEMS with the confidence that these systems will provide superior performance.
  • TEST CRITERIA: Prototype tested, NEMA MG1-22 evaluation, System torsional tested, Motor starting ability.
  • SOLID-STATE, FREQUENCY COMPENSATED VOLTAGE REGULATION: This state-of-the-art power maximizing regulation system is standard on all Generac models. It provides optimized FASTRESPONSE to changing load conditions and MAXIMUM MOTORSTARTING 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 TRANFER 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.
