Generator Overview

While smaller generators can power your most essential items during an outage, this size generator can backup your entire home. It runs very clean, quiet and last an incredibly long time. Since it is powered by a Perkins engine, it can run for up to three weeks without needing an oil change. The longer run time diesel standby generators like this one provide makes them ideal for backup power.

Traditional generators are not able to run full time. They often require an oil change every 100 hours.  This generator can operate up to 500 hours before it needs service.  The next time the power fails, you can continue living normally and enjoy all the comforts of your home.

This 20,000 watts whole home generator uses a four-cylinder engine that works in perfect balance. Four strokes, four cylinders, this type of engine design results in lower vibrations, steady, consistent power and efficiency. ; Our Perkins engines provide 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.

This generator is available with the canopy enclosure.  The difference is the protection it provides and the lower noise level.

Generator Controller - Features & Functions

For clear generator instrumentation, protection and control, this generator uses a DynaGen TG350 Controller. 

DynaGen Generator Controller TG350

Main Features

  • Designed for Extreme Shock and Vibration
  • Easy to use front panel buttons
  • Manual or Automatic Starting
  • Exerciser Clock
  • Maintenance Counter
  • Passcode Protected
  • Automatic shutdowns and warnings
  • Pre-heat and post-heat timers

  • 5 Year Manufacture Warranty
  • Load Monitoring (TG410 Model Only)

There are two versions of this controller. The TG350 is included. The TG410 is an optional upgrade. With the TG410, current sensors can be used to monitor generator loads / power consumption.  One other feature is the "Can Bus" port. Like a vehicles ODBII connector, it lets you communicate with the generator for remote monitoring and control.  You will need the TG410 if you wish to use this in the future. 

Monitoring Functions

Engine Temperature

Engines normally use an engine coolant temperature switch and oil pressure switch. They only turn on or off when there is a fault and do not let you read actual engine temperature. We feel it is important to know how hot the engine is running and detect an issue before it becomes necessary to shut down the engine. For this reason, we include an additional sensor to monitor the coolant temperature so that if it ever reaches a warning level it will notify you and log the condition. If a critical level is reached the generator controller will shut down the generator. For added protection the generator controller is additionally set to log four set points. High and Low warning levels and failure levels.

Radiator Coolant Level

Aurora Generators are equipped with this additional sensor in the radiator to eliminate low coolant level. It is engineered from high quality corrosion-resistant materials to accurately and reliably alert the generator controller to low coolant level and shut down the generator. Engine temperature sending units/sensors alone are supposed to detect overheating. However, if coolant level is low, temperature sending units/sensor's cannot measure the coolant temperature. When coolant level in an engine is low, the cooling system cannot adequately remove excess heat from the engine.

Oil Pressure

Oil pressure is an important factor in the longevity of an engine. Oil pressure ensures that the metal parts moving in the engine, never touch each other. An oil pressure switch is standard on every engine / generator. Should oil pressure ever be lost, the engine controller will shut down the motor.

For some installations, customers maybe required to keep track and log the actual oil pressure.  For this, another optional oil pressure sending until is available. Knowing the actual oil pressure will help you know if the engine has warmed up, oil is flowing as it should, filters are not plugged, oil is breaking down or engine wear is happening and service is required.  

Fuel Level

Aurora fuel tanks have a fuel level sensor installed. The controller can display a warning when fuel level is low. The generator can be set to shut down before its empty. Shutting down before it is empty helps prevent difficult starting caused by air that enters the fuel pump and fuel injectors.

Generator Output

The generator controller monitors the power generated by the alternator. From the output voltage it can determine the engine speed in rpm, alternator frequency and voltage output are correct.  If they start to fall outside of set normal ranges, it will warn you and log it for future reference. Any critical errors will cause the generator to safely shut down.

Diesel Engine

This generator uses a small and compact yet powerful four-cylinder diesel engine from Perkins.  Perkins engines offer exceptional performance and long life.  Perkins engines are radiator cooled, slow turning engines that can run full or part-time.  Perkins engines require less oil, air, and fuel filter changes (every 500 hours depending on load factor). The low fuel consumption and ultra-compact engine offer all the customer benefits experienced from larger engine sizes. The engine has a proven record and has been in use worldwide for many years in providing power for homes, business and construction equipment.
