Sales & Installation Of Standby & Other Units
A generator dealer serving Salt Lake County and other northern and central Utah locations, T-Rex carries a comprehensive lineup of portable units for everything from recreation and the outdoors, to backup power for residences and small businesses, to construction and contracting work. In addition, T-Rex Generators supplies permanent standby units to Salt Lake County homes and commercial entities. Whether you're in search of a portable model to run the rooftop AC in an RV, or a standby generator to provide backup electricity in the event of an outage or natural disaster, we have a machine that will fit your needs. In addition to portable and standby units, T-Rex also carries tractor-driven or PTO generators, the most economical means of producing end-user electricity for anybody with a tractor or PTO-equipped vehicle.
Anyone who is purchasing a motorized generator for local use should be conscious of altitude and summer temperatures when models for a given application are being considered. According to Wikipedia, Salt Lake City's average elevation is 4327 feet above sea level, and other parts of the County can be slightly higher or, in the case of mountainous regions, significantly higher. July, the county's warmest month, can easily boast temperatures of 95 degrees Fahrenheit. Why are these numbers important? Let us explain it....
Altitude and temperatures have an impact on generator operation across Utah because manufacturer ratings of running and surge watts are always made at sea level, and in moderate to warm temperatures (no higher than 85 degrees). Any deviation from these idyllic conditions will begin to erode a generator's 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 begin to suffer, especially if a generator is being operated at an altitude like ours. 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 (using Salt Lake City's 4327 feet as an example) multiplied by the projected power loss (3.5%) divided by 1000 feet (4327 x (3.5/1000) = 15.14%). In Salt Lake City, a 3000-watt generator will produce roughly 2550 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.
