We Sell And Install Standby And Other Generators
Utah residents who are in need of whole-house or portable emergency generator should visit the T-Rex Generators online showroom today. View our selection of tractor-driven or power takeoff, installed standby, and industrial and work-site portable units. For convenience during a power outage or natural disaster, automatic standby generators are unmatched. Once installed, these machines require no hook-up or preparation to restore electricity to your home or business. PTO or tractor generators, thousands less than standby units with comparable output, provide anybody with a PTO-equipped vehicle an economical means of creating end-user electricity for projects or backup. Or consider taking one of our ultra quiet inverter models on your next camping or hunting trip! These quiet and lightweight generators can be perfect for running the rooftop AC of an RV, and, unlike many conventional generators, are safe for sensitive electronic devices and tools.
Anyone who is purchasing a motorized generator (especially true of small-engine powered portable and residential standby units) for use in the state of Utah needs to be cognizant of two factors that can adversely affect the product's performance: elevations and summer temperatures. Utah is composed of altitudes that far exceed sea level. For instance, our capital has an average elevation is 4327 feet (above sea level). Other areas are higher. Park City has a base elevation, according to Wikipedia, of 6900 feet. Provo's is 4551, while Cache Valley registers an elevation of roughly 4450. All residents are also keenly aware that summer temperatures here can easily meet or exceed 90 degrees Fahrenheit. Some (especially southern) locations can regularly beat 100 degrees Fahrenheit. Why are these numbers important? Continue reading....
Altitude and temperatures have an impact on generator performance because manufacturer ratings of running and surge watts are made at sea level, and in moderate to warm temperatures (no higher than 85 degrees). Any deviation from these idyllic conditions will erode output. For every five-degree temperature increase (over 85 degrees F), output tapers off by a consistent 1%. An increase of one or two degrees normally won't be tangible. If outside temperatures reach 100 degrees or more, load performance can certainly suffer, especially if a generator is also being operated at high altitude. For high-altitude generator operation, the rule of thumb is 3.5% loss of output (includes both running and surge watts) for every 1000 feet gained in elevation (above sea level). Power loss at any elevation can be calculated like this: altitude of location (let's use Park City's robust 6900 feet above sea level for this example) multiplied by the projected power loss (3.5%) divided by 1000 feet (6900 x (3.5/1000) = 24.15%). In Park City, you can expect a portable generator to lose one quarter of its power. In Park City, a 5500-watt generator will produce approximately 4200 watts.
Heat and elevation don't always require a more-powerful generator. If you know in advance, however, that the load you will be running requires full generator capacity (or if all available surge watts are needed to start an electric motor - such as the motor in an RV air conditioning unit), then you will have a choice - between obtaining a larger machine than you would need at sea level or simply not running the load. Any time your intended load is considered critical (you can't afford to have it fail), if it consumes all of a generator's rated (sea level) capacity then you will have no choice but to seek a larger model.
