Whole Home Power Generator

While smaller generators can power your most essential items during an outage, this size generator can backup your entire home. Clean, quiet and incredibly long life engine that is designed to run for up to three weeks without an oil change. The next time the power fails, you can continue living normally and enjoy all the comforts of your home.;

This 20,000 watt whole home generator uses a four-cylinder engine that works in perfect balance. Four stroke, four cylinders, this type of engine design results in lower vibrations, steady, consistent power and efficiency. ; Our Perkins engines provide for a super long life and incredible durability. Automatic start controller, direct drive alternator, built-in fuel tank, and advanced genset controllers are used.  We build using only stainless steel hardware, and we build them to outlast all other comparable generators.  Aurora generators are so strong we even offer double the warranty of any other brand generator.


  • Engine - Small engine with the same exceptional performance and long life as the larger Perkins engines. Liquid cooled, four cylinder, 2.2-liter engine is suitable for both prime and standby power use. Enjoy fewer oil, air and fuel filter changes (every 500 hours depending on load factor). The low fuel consumption and ultra-compact engine offers all the customer benefits experienced from larger engine sizes. The engine has a proven record for hard working reliability in transport truck auxiliary power units to refrigeration units.
  • Generator Alternator - Aurora industrial class alternators are highly reliable and produce clean, stable power even in harsh conditions. Automatic Voltage Regulated to 0.5% precision. The alternator is brushless and requires no maintenance. The generator head is directly driven by a heavy engine flywheel. The large rotating mass helps to reduce fluctuations in power when heavy loads are applied.
  • Fuel tank - Integrated generator fuel tank helps to simplify installation and reduce generator footprint. Fuel tank uses a mechanical fuel gauge for quick checks between usage and a second electronic gauge. The electronic gauge is monitored, and fuel levels is displayed by the generator controller. If the fuel level is low and / or a safety shutdown occurs before the tank is empty, the display will show you.  This feature helps reduce downtime or service calls by preventing the engine from running dry.
  • Digital Generator - Clear generator instrumentation, protection, and control. 150 event logging, fuel level display and alarm, maintenance and exercise clock, and much more. The controller is built to withstand severe duty, extreme shock, and vibration. Easy to use and configure via front panel buttons. Can be used manually or with fully automatic starting with a transfer switch or wireless remote control. Accepts additional customer sensors and switched outputs.

  • Preheating & Post-heating- Pre and Post glow plug heating phases can be used in this generator. Preheating helps with the initial starting. Post-heating is used after the engine has started to help reduce false starts, rough idling, lower start-up emissions and warm up your engine faster. False starts are detected, and automatic recovery will restart if necessary. If required, this feature makes automatic starting simple.
  • Maintenance and Exercise Clock - It is easy to lose track of how long your generator has been running without it. The maintenance clock keeps track of your run time and is set to remind you when it is time to do an oil change. The exercise clock is also programmable as is the low battery voltage detection that can also trigger an exercise cycle if desired.
  • Acoustical Sound Enclosure - Weather resistant enclosure is constructed out of galvanized steel and assembled with high strength stainless steel fasteners. Tough powder coated finish, acoustic sound insulation, and chrome lockable doors are just some of the great features. The neutral gray color is cosmetically appealing and easy to care for.
  • “Canada Proof Battery” - Canadian Energy commercial battery is built to withstand severe duty, perform in the toughest conditions, and endure repeated shock and vibration.
  • Engine Warranty - Perkins engines come with a two-year or 3,000-hour warranty
  • Generator Warranty - Aurora Generators come with a five-year limited warranty.
  • Beyond The Standard Engine Warranty - There is also an option to buy a Perkins Platinum Protection policy to cover you beyond the standard warranty period. Up to 100% components covered, transfer coverage to a new owner adding value to your generator if you wish to sell it, and you can buy the extended coverage anytime before your standard warranty coverage expires.
