4kW Small Diesel Generator

If you are living off the grid, you know the sun does not always shine, and the winds don't always blow.  Many find that their power needs often exceed the capability of even a well-designed system, so they turn to generators.   The problem with most generators is they are only designed for short term use and offer no warranty for any off-grid application.  Not so with this small diesel generator.   The engine is made by Perkins who has a well-earned reputation for after-sale onsite service and support.  Between Perkins  warranty and our own 5 Year warranty, you can operate your generator for weeks at a time knowing that your covered.     

Since it has an engine life of over 15,000 hours and uses less expensive diesel fuel, your investment quickly pays off.   If you need more power, consider our 8kW Generator instead. It is the same size but produces double the power. 

  • Engine - Small engine with the same exceptional performance and long life as the larger Perkins engines. Liquid cooled, two cylinder, 0.5-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.
