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. Roy's elevation is 4541 feet or 1384 meters above sea level. July, the city's warmest month, boasts an average temperature of roughly 90 degrees Fahrenheit. Why are these numbers significant? Let us explain....
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 (4541 feet above sea level here in Roy) multiplied by the projected power loss (3.5%) divided by 1000 feet (4541 x (3.5/1000) = 15.89%). Here in Roy, a 5000-watt generator will produce in the neighborhood of 4200 watts (having been robbed of nearly 800 watts by high-altitude operation).
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.
