Ultimate Protection, Ultimate Performance
Keeping America Powered for Over 20 Years
Pros and homeowners who want the best trust NorthStar generators' proven history of providing utility-grade electricity for reliable backup power, job sites, home projects, recreation and more. For over 20 years, NorthStar has set the portable power standard by engineering, assembling and rigorously testing all generator models at our state-of-the-art facility in Faribault, MN. Only premium quality components are used and each generator is backed by an industry-leading warranty. Trust NorthStar for dependable power in every situation, performance you can count on in emergencies and on the job.
Trusted in Emergencies
Powered by Honda Reliability
This NorthStar generator uses a top-of-the-line, commercial-grade Honda engine. This amazingly reliable, smooth-running engine provides everything you need on the job or in emergencies — easy-start convenience, improved power, greater fuel efficiency, longer run times and quieter operation.
Backed by Honda Durability
With an outstanding 3-year limited warranty, the Honda GX engine adds even more value to your NorthStar generator. You get smooth, robust performance plus years of worry-free dependability.
Clean Power Keeps Electronics and Appliances Safe
Today's appliances and electronics need clean power to run effectively. Clean power is smooth, steady power with low harmonic distortion. With less than 5% harmonic distortion at full load — the same as electricity from the utility company — this NorthStar generator provides reliable performance whenever you need it. Other brands advertise no load distortion levels yet actually have distortion levels as high as 20-30% at full load. Be sure to compare distortion levels at full load rating.
Engineered To Perform
Copper Heads Are Worth their Weight in Gold
Generator heads are often overlooked when it comes to choosing a generator. But their importance is key. NorthStar generators use oversized generator heads with 100% copper windings to provide the ultimate reliability and performance. Unlike other brands that use aluminum heads, we use copper-wound heads to allow your generator to run at full load continuously for weeks, if necessary, without the risk of overheating.
Less Vibration Means Less Wear, Longer Life
Excessive vibration is enemy number one to generators, causing premature wear and failure of generator components. Our advanced V-mount vibration isolation system helps create a solid foundation to extend generator life, adding optimum flexibility and support. Captive vibration isolation mounts protect the generator when being transported and an optimized vibration control system provides smoother operation and less metal fatigue.
More Outlets Handle More Jobs
When you're facing a power outage or a demanding project, it's good to have options and this NorthStar generator gives you plenty. A full bank of up to 10 outlets allow you to power more tools, appliances and essentials than other brands. Plus, a built-in volt meter and hour meter provides feedback at a glance.
Fully Equipped
High Performance, Low Maintenance
This NorthStar generator is designed with all the extra features you need to keep power going in tough times. An extended run fuel tank reduces refilling and power interruptions. Variable Timing Digital CDI ignition offers excellent starting and high-power output. Tubular full steel roll cage construction with anti-rip V-mounts provide rock-solid protection. Locking plug outlets allow for easy connection to a transfer switch to get power up and running in minutes. You can also add a wheel kit for maximum portability.
Built To Last
Engineered to Last Up to 8 Times Longer
When it comes to quality, we're in a class of our own. NorthStar generators are designed and manufactured to last up to eight times longer than other brands.
Over 1000 Hours of Testing
Nobody tests generators more than we do. NorthStar engineers test each generator design to the point of failure to make sure your generator won't fail you. Thousands of hours of rigorous real-world testing situations in our Faribault, MN testing facility ensure optimum performance and maximum life. A test report is included with every generator to verify it is as good as the one we tested.

When using the four(4) 120v 20amp outlets, which outlets are on which hot leg of the power circuits? For the sake of keeping the load as balanced as possible, is it 'X' on the left & 'Y' on the right? or perhaps every other one? Thanks!

On the generator panel the four 120 volt 20 amps outlets on the left are 1 leg and the 4 outlets on the right are 1 leg.
