St. George, UT Generator Warehouse
Sales & Installation Of Standby & Other Units
Residents of St. George, Utah who need a 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 for local use should be conscious of altitude and summer temperatures when models for a given application are being considered. The average elevation of St. George is 2860 feet above sea level. In the middle of summer, temperatures here can easily surpass 100 degrees Fahrenheit. Why are these numbers significant?

Altitude and temperatures have an impact on local generator operation 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 generator conditions will begin to 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 begin to 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 (2860 feet in St. George) multiplied by the projected power loss (3.5%) divided by 1000 feet (2860 x (3.5/1000) = 10.01%). On a typical summer day in St. George, you would expect to lose around 13% of your unit's rated output or sea level capacity (losing 10% for altitude, and another 3 - 4% for ambient temperatures).
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.
