Most gen sets say that. I have 2 & never a problem. They have the HA Jet, here's a you tube on how to install. Imaginary problem solved!
How does altitude affect a generator’s performance?
All generators operate on the combustion that requires oxygen. But at high altitudes, the oxygen available in the air becomes lower and lower so much so that the generator no more runs fine and faces operational difficulty.
Without proper combustion, the generator can lose power, and its performance efficiency can drop by 3 percent at a higher altitude. To counter this issue, some generators come with a high altitude kit for enhanced operation above sea level, which offers a simple method of adjusting the air/fuel ratio by injecting a limited amount of fuel into the carburetor.
How do I estimate generator power loss at high altitude?
Any motor will create a given measure of force dependent on how much fuel and air it burns-through. High power burdens and RPMs burn-through more fuel. Since fuel and air are in a to some degree consistent proportion, the motor will require more air at higher power yields. Lamentably, as we drive our RVs up into higher rises, the air gets more slender and the motor loses it’s capacity to deliver it’s greatest evaluated power. This outcomes in a comparing drop in generator yield wattage.
Various motors will respond in differing sums. For example, the yield wattage of the Onan Marquis Gold series of gas fueled generators will lose 3.5% for each 1,000′ in height gain more than 3,000′. The Onan QuietPower Diesel 10,000 watt will derate 3.5% for each 1,000′ more than 500′ and it further derates by 1% for each 10 degrees F expansion in temperature more than 85 degrees F. A decent guideline for most gensets is that you will lose 10% of the appraised yield each time you gain 3,000′ in elevation. This implies that a 7,500 watt generator running at 9,000′ of elevation may be fit for creating somewhat more than 5,000 watts at that height.
Diesel motors are really well ready to deal with the fuel infusion prerequisites at higher heights yet carbureted gas controlled motors don’t have that extravagance. The Onan Marquis Gold series of generators utilizes carburetors. These gensets do have a height pay change on the carburetor. By dialing in a higher height you will incline out the combination to forestall flash fitting fouling and exorbitant smoke. It is vital that you additionally dial it back when slipping to bring down heights or probably the motor will run lean and you will consume the motor’s valves.
What are the other environmental factors that impact the performance of a generator?
Apart from high altitudes, temperature fluctuations, and changes in humidity levels also impact a generator’s performance. High temperatures also mean thinner air causing similar problems as caused by the high altitude. Meanwhile, water vapors present in the environment with very high humidity can displace oxygen resulting in impaired combustion. Be it altitude, temperature, or humidity, all these factors impact the availability of oxygen in the air and result in inefficient combustion.
