The high point of the unit is its surge/continuous power capabilities, which greatly exceeds the standard of residential backup power generators. In other words, the 9,375W surge power ensures that you will experience no problems in starting up more pretentious appliances, whereas the typical 7,500W running power is more than you will ever need to run them at optimal capacity for up to 8 hours.

  1. I own two Generac devices.

    Like all Wisconsin-built equipment, they function forever, or at least as long as you’re kind and generous with the oil changes.

    The first is a 1500 watt “Niagra” series with B&S Vanguard 6.5 HP OHV. The alternator was manufactured in 1980. It’s the second engine. It’s almost *too*easy to start. Pull the rope until it reaches the compression stroke, and a 6-inch tug start. It’s on the second engine, having worn saw commercial service for 15 years, then got a new engine. (Cylinders aren’t worth re-boring on such a small engine). After 35 years service, it’s still running strong.

    It says “1500 watts” and it *MEANS* 1500 watts. It easily handles running 4 space heaters at 1500 watts each, for a minute, demonstrating a lengthy 25 percent surge. Dandy!

    The second is only 22 years old, and its first engine is nearly broken in.
