You’ll find Northern Lights generators wherever prime power is needed. We began building Northern Lights sets to power the Alaskan bush country in 1963. Today our sets and dealers are at work world-wide.

Designed for farm tractors, the long stroke engines that power the NL843NW3 have the low end torque needed to start big electric motors. Dependable too; some sets have logged over 25,000 hours with just routine maintenance. All operate at 1800 rpm (1500 rpm for 50 hz). This is half the speed of light duty 3600 rpm sets. Half the wear and tear, too.

This set meets US EPA Tier IV emission standards. The built-in muffler reduces exhaust noise so well that an additional muffler is not needed.

Economical operation is a necessity in remote areas where fuel is expensive. These diesel sets use less fuel than comparable gasoline sets. Diesel is also less expensive and much safer to transport and store.

Northern Lights are easy to install, operate and maintain. Each has a self-venting fuel system, mounted control panel and is ready for connection to your electrical distribution system. Just add a battery and fuel, and you have power at the touch of a button.

Service is easy, too. All the maintenance points are on one side. Low oil pressure and high coolant temperature shutdowns protect your investment.

Every Northern Lights has been fully load tested before shipment. This is part of a quality control program that assures your satisfaction and years of service.

Let them show you the set that is right for you. They will also explain the options available to customize the set to meet your special power requirements.
